Greenhouse gardening can be a beneficial method for controlling environmental climate, growing plants for multiple purposes, and controlling sunlight and heat penetration. However, it is important to consider the potential risks associated with tanning in a greenhouse. Sunburn can occur due to UV rays, while burning is mostly from infrared radiation. Glass acts as a filter, taking out all non-ironizing radiation. In greenhouses, the transmission of UV depends on the glazing material. Ordinary glass transmits 65 to 75 percent of UV-A but 3 percent or less of UV-B.
Greenhouse workers may be susceptible to risks associated with ultraviolet (UV) radiation in skin and eyes. To avoid getting a sun tan, it is recommended to use sunscreen and avoid the sun’s strongest rays, which could cause burns. A polytunnel covered with a standard or Thermal Anti Drip polythene cover can help achieve a suntan.
In summary, greenhouse gardening can provide an ideal environment for plants, controlling environmental climate, and reducing the risk of burns. However, it is crucial to use sunscreen and avoid the sun’s strongest rays when tanning in a greenhouse. Additionally, greenhouse workers may be susceptible to risks associated with UV radiation in skin and eyes, even if they are in a space beneath a plastic cover.

Where is the best sun position for a greenhouse?
To maximize light and plant growth, it’s recommended to have one of the longest walls facing south or within 20 degrees of south. This orientation provides morning, mid-day, and afternoon sun. Standard Sturdi-Built Greenhouse features include exterior glazing, thermal option, bayliss solar vent openers, orchid gardening, cannabis greenhouse, and all ability greenhouses. Other options include Deluxe Glass-to-Ground, Garden Deluxe, Nantucket, Solite, Trillium, Tropic, and Tudor.
Is sitting in a greenhouse good for you?
Greenhouses offer excellent air quality due to the presence of plants, which improves lung health and strengthens immunity. This is particularly beneficial for patients in cities exposed to poor air quality and high pollution levels. Solar Innovations, Inc. offers multiple vent and fan options for any glass structure, ensuring adequate air circulation. Plants and flowers provide a calming environment for recovering patients, and incorporating a koi pond and other water features can further enhance the rehabilitation facility’s soothing qualities. Solar Innovations’ greenhouses are ideal for rehabilitation centers of all types, and more information on popular uses and customization options can be found on their website.
Does sunlight penetrate greenhouse?
A greenhouse is a trap for the sun’s radiation energy, which penetrates through transparent walls. As sunlight reaches darker surfaces of plant leaves or soil, it is partially absorbed and converted into heat and partially reflected. The heat builds up inside the greenhouse, causing temperatures to rise. To prevent overheating, selective ventilation or cooling systems can be used. Glass or transparent plastic film walls are not necessary, but plastic films are easier and more flexible.
Mulch films, used on about 4, 000 hectares of arable land in Germany, are black films that cover the soil around field-grown crops like vegetables, strawberries, or sweet corn. Under these conditions, no weeds grow, moisture is retained more effectively, and fertilizer is not leached out quickly. In the cool spring season, they raise the soil temperature by at least two degrees Celsius and function as a mini greenhouse for the roots, allowing earlier planting in vegetable plots.
Light stabilizers are used in various industries, including the coating industry, adhesives and sealants, and photovoltaic cell production. They retard the degradation of materials and their embrittlement, providing a longer life time for these products.
Do greenhouse gases absorb UV rays?
The greenhouse effect is a phenomenon where the Earth’s atmosphere heats up its surface to higher temperatures than normal due to the radiatively active gases in the atmosphere, such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. These gases radiate heat energy in all directions, some of which is directed towards the Earth’s surface, leading to surface heating. The rate of heating depends on the temperature of the atmosphere and the amount of greenhouse gases present.
The sun releases UV, infrared, and visible radiation, which is received by the Earth. The atmosphere and clouds redirect most of the incoming solar radiation, some of which is absorbed by the clouds and atmosphere, while the rest is absorbed by the Earth’s surface. This part of the radiation absorbs, heats up the Earth, and converts it into heat, leading to global warming.
The greenhouse gases contribute differently to the greenhouse effect, with water vapor contributing 36-70%, carbon dioxide 9-26%, methane 4-9%, and ozone 3-7%. The greenhouse effect can be natural or man-made, with human activities leading to increased concentrations of greenhouse gases. This leads to global warming, depletion of the ozone layer, smog and air pollution, and acidification of water bodies.
Can you get vitamin D through a greenhouse?
A conservatory greenhouse offers numerous benefits, including increased vitamin D production, stress reduction, and therapeutic benefits. Sunlight exposure is crucial for vitamin D production, which is essential for bone health, immune function, and overall well-being. Gardening activities can also promote relaxation and mental health by fostering a meditative state and lowering blood pressure. The rhythmic nature of gardening can also lower muscle tension and improve mental health.
Additionally, a conservatory greenhouse strengthens our biophilic connection with nature, boosting creativity, productivity, and cognitive function. The presence of plants in our surroundings nourishes our innate need for connection with the natural world. Overall, a conservatory greenhouse provides a perfect environment for these benefits.
Is a greenhouse full sun?
The greenhouse, as a sunbathing spot for plants, benefits from full sun exposure, allowing it to absorb all the warmth it can get. This leads to a significant solar heat gain, creating a cozy microclimate beneficial for plant growth in cooler climates. Additionally, sun-drenched greenhouses have reduced humidity levels, providing a unique advantage in terms of air quality and overall greenhouse performance.
Can you get tan through a greenhouse?
Greenhouses provide a comparable tanning environment to that of solar radiation, thus facilitating a similar tanning effect. Nevertheless, it is of the utmost importance to utilize sunscreen and to avoid exposure to the sun’s most intense rays in order to prevent the occurrence of burns, as these rays have the potential to cause such injuries.
How do I reduce the sun in my greenhouse?
Shading is a cost-effective method for cooling greenhouses, often applied outside over the glazing or with screen systems inside. It can result in lower electric bills if fans are used. Shading compounds, which are applied in the spring, wear off before the first frost. Some growers add additional layers of shading as the sun’s intensity increases during summer or the shade material wears off.
An alternative is woven or knitted shade fabrics made from materials like polypropylene, saran, polyethylene, and polyester. These lightweight, easy-to-apply fabrics are available in various degrees of shade and are typically custom-fabricated to fit the greenhouse. Most materials are ultra-violet stabilized and have a lifespan of about 10 years. Costs range from 10-40¢/sq ft. Polypropylene is strong, tough, and resistant to flexing, abrasion, and chemical attack.
Saran is fireproof and shrinks about 3 when installed, while lock-stitched, knitted polyethylene netting is fire and mildew resistant. Metalized materials like Aluminet (GREEN-TEK) can moderate both day and night temperatures.
Should you use a greenhouse in the summer?
Greenhouse seed starting is crucial for gardeners to prepare for their second growing season in the greenhouse. Starting plants early in late summer or early fall allows for sufficient light and mature plants to grow in the greenhouse through the colder months, providing a year-round harvest. Starting seeds too late can result in reduced light levels and spindly plants. Growers can start crops in trays or directly in the soil, depending on their planting plan.
The seeds planted for the second growing season depend on the local climate and greenhouse design, so they should be planned well in advance. For guidance on growing in a greenhouse in summer, check out the Year-Round Greenhouse Planting Calendar. For more information on climate control during warmer months, visit the blog “How to Keep My Residential Greenhouse From Overheating?” or “How to Reduce Heat in Your Greenhouse with Shade Paint”.
Can greenhouses trap some of the sun’s rays?
A greenhouse is a glass structure used for controlling temperature and humidity for plant cultivation or protection. It traps heat from the sun’s rays inside, keeping plants warm even in cold weather. The Earth’s atmosphere absorbs Earth’s heat, causing the greenhouse effect, which traps some of that energy. Greenhouse gases, such as carbon dioxide, water vapor, methane, ozone, nitrous oxide, and fluorinated gases, are responsible for this effect.
These gases absorb heat and release heat energy, which is often absorbed by another greenhouse gas molecule. Although greenhouse gases don’t have a hard surface like glass, they have a similar effect on keeping the planet warm. The greenhouse effect keeps temperatures mild and suitable for living things, and the greenhouse effect is a significant concern for our planet.
Do you need UV in a greenhouse?
UV-C and UV-B are high-energy wavelengths used to decontaminate water and surfaces, killing micro-organisms. They could also be delivered to plants to kill pathogens on leaves. UV is also used by insects to help navigate to flowers, making it difficult for pollinators and pests to locate flowers in a greenhouse. However, excessive UV doses can damage and kill plants, and can cause skin cancer and temporary or permanent eye damage. To ensure safety, all UV devices should have warning labels and extreme precautions should be taken to prevent people from being exposed to UV treatments without protective equipment.
📹 Can You Get a Sunburn Behind a Window?
If you’re not lounging on the beach on a hot summer day, why would you think to put on sunscreen? Well, you might need …
1:58 you might want to edit this part, the UV-B that hits the window is about 0.5% of the total energy from the sun while around 50% is infrared. So while it’s technically true that UV-B rays heat the window, the infrared light heats it up around 100 times more. It’s a bit like saying that a sauna gets hot because your body heat heats it up. It’s technically true that yout body heat warms the sauna, but the vast majority comes from the stove/electric heater.
There was a case with a woman that worked in a sewing workshop (if my memory serves me right), and she had a window on one side of her that exposed only half of her face to sunlight every day. After many many years of her working there, on that same spot and layout, you were able to visually see which side of her was exposed to the sun all these years from the aging of her skin being noticably more advance on one side.
Thank you, this explains my furry, cute, kitty housemate! He was getting sunburn on his adorable little ears, and it still happened when I was keeping him inside due to injury. I thought glass blocked all UV, so I was a bit confused. Now the vet recommends I give his ears a little sunscreen every day. He’s really not a fan but he’s a good little floofball so he lets me.
Nutritional scientist here to answer the 49 comments asking “but can you get vitamin D through windows?” No. UVB rays facilitate vitamin D production in your body, and glass blocks most UVB. “Then should I take vitamin D supplements?” Yes, probably. This is still a bit debatable as the problem with swallowing a supplement is ensuring that your body utilizes it properly. But we tend to agree that supplements don’t hurt and likely help. What we ultimately assume is this: people are not good at wearing sunscreen. They tend to under-apply if they wear it at all. Thus, we recommend sunscreen with this assumption in place – after all, you don’t need copious amounts of UVB exposure in order for your body to make vitamin D. If you are the rare person who applies sunscreen properly/reapplies even if indoors, then please do talk with your doctor about monitoring your vitamin D levels.
As a cautionary note, if you live in a region of the world that doesn’t get much sunlight year round, not getting enough UV light can interfere with your body being able to synthesize vitamin D and also not getting enough natural sunlight can worsen seasonal affective depression. This is especially true if you spend most of your time indoors.
My grandmother told me you can get burnt on a cloudy day. She had to get treated a number of times for skin cancer. She was blonde. I used to get painful sunburns that hurt for days and the skin peeled a lot. I try to stay out of the sun but I can still get a burn. Since I read about a burn study done on vitamin E, I have started using it on my burns. I was surprised to not have the pain for days. Usually by the next day the pain was gone. And the peeling is minimal. It works better than anything else I’ve tried. It also works on burns I have gotten in the kitchen and when I worked with a blow torch. Got some really horrible burns that by the next day did not hurt and did not blister much. Healed fast too. Can’t really see the scars. But you have to use it right away. You have to use the oil you squeeze out of the vitamin capsules. Any other vitamin E is too diluted. It helps if you not only put it on the burn but also put some on gauze and bandage that onto the burn for a few hours. Re apply as needed.
Being allergic to the sun, I rash through everything. I’ve always burned through my car window. Left arm always got bad, and I had a rash on my forehead all the time just from driving back and forth to work. A few years ago I was put on a medication that made my allergy a lot worse. Just jumping into the back seat of an SUV and then running into my doctor’s office for an appointment made me burn. No one should ever take for granted the damage the sun could be doing, especially if they’ve recently been put on new meds.
Sunlight is important for stimulating many processes in the human body. As is, we receive low amounts of important Sunlight through our indoor lifestyles. Our regular window glass blocks out some of the important visible and especially invisible wavelengths, solar films and other coatings can further reduce the passage of these wavelengths. Similarly, sunscreen blocks out some of the important wavelengths and in doing so prevents the stimulation of some important processes in the skin. For example, our skin needs specific wavelengths of Sunlight to produce “Vitamin D”, a deficit of Vitamin D is partially responsible for many modern diseases. If we block these wavelengths out from reaching our skin, with windows, sunscreen, solar films and other coatings, we risk interfering with some of the important processes in our skin.
Odds are though that any light passing through the window to reach you in your home is early morning or late evening light where the solar angle is very shallow, making the UV index much lower. That coupled with the partial blockage from the glass will make that 20 to 30 minutes of exposure basically harmless. I wouldn’t worry about that short time warming up under the sunlight because the positive effects on mental health probably outweigh the negatives. However, if your in window light for hours or have sunroof windows, having a film over them probably would be smart.
Whether you get sun exposure, when (at noon or after UV light is mostly gone), how long, etc, as well as your skin tones, determine whether you should wear sunscreens or not. Vitamin D deficiency is a huge problem, and supplements have NOT been shown to result in better health, just higher Vit-D levels. (They’re different structurally from natural Vit-D produced by the body from ultraviolet exposure). Some people don’t use enough sunscreen while others use way too much.
Personally, as someone that is white as a ghost, I think we might be going a bit overboard if we are starting to apply sunscreen indoors. I agree if you happen to be suffering from sunburns or such effects. But it seems like we are going a bit insane here with very minor risks. Here is a thing that might scare people a bit. But I think is important to understand. Your lifestyle effect your chance of getting cancer. But a lot of it is still just random. So it is better to focus on the lifestyle choices that has great effect on your health than the minor ones. Since a lot of those minor ones will not really have a greater impact on you then random cellular mutation that is pretty much impossible to avoid. Therefore, I think we should put more effort in to finding treatments for cancer, since it will be enviable. And the longer people live, the great chance there will be. Ageing itself will be the greatest contributor to cancer. Preventive measures can not be the only thing we focus on. But detection and treatment is equally if not more important. But do wear sunscreen outside and do not smoke. Like I said. There are high-risk factors you should avoid. It is the minute things you do not have to stress about.
If that applies to door auto glass it may explain the weirdest sunburn I ever had. Helping my sister move from Seattle back to San Diego one summer by driving the U-Haul for her I burned my upper left arm. It was two clear sunny days of driving south down I-5 with the windows up and A/C on with my arm resting on the door sill up against the glass. Growing up in SoCal I was no stranger to sun burns but this seemed different in the way it looked, felt, and healed. It actually left a discoloration in the damaged area that you can still see 40 years later. I wonder now if it was a deep tissue UV-A burn as opposed to a UV-B burn I was used to?
I recently got new windows. Double pane, Low E, Smart Sun, Anderson windows. Even though I’m in a cold climate where some people want to let some warmth from the sun in during winter, I wanted to block all the sun. I kid you not, stand in front of the old windows, feel the heat from the sun beating in and heating everything up. Stand in front of new windows, feel nothing, I love it.
“Can You Get a Sunburn Behind a Window?” well this is a question no Aussie needs a article to learn the answer to lol Very common to have the right arm browner than left, due to it being closer to the window on the driver’s side of a car & even with air con on & window closed, the browning & burning is still normal
Certainly HOME windows are pretty safe since the sun angle usually means it’ll only shine in at low angles, so before 10am, or after 4pm in the summer, so the atmosphere is blocking a lot more radiation then, even without window glass to help. OTOH, it does make sense maybe all of our windows should be tinted if it helps block unwanted frequencies.
I am allergic to UV light and still have reactions indoors if in a room with sunlight coming through closed windows. So yeah, UV light gets through. I keep the curtains closed in the room in which I spend most of my time so I don’t have to wear sunscreen all the time. I’d much rather be in a dark room than wear sunscreen.
I’m photosensitive and break out in hives after about 30 minutes. Once after napping in front of a shaded window the sun was shining through the blinds and left a line of hives across my arm. I keep it pretty dark in the house and can’t go outside without sun glasses or long sleeves and a preemptive benadryl. Tell me a vampire joke bc I’ve never heard that one before… My life is not fun sometimes. 😐
Yes you can I don’t need to watch the vid. My wife and i went to Florida for a week and on the way to the airport to leave we had the windows up and ac on she had short ma on and by the time we got timo the airport she had a sun burn on her upper right leg due to sun coming thru the passenger windows
Sunscreen is greasy and has ingredients which are not water soluble (which is why you can still feel it on your skin after a shower), I can’t imagine it’s something you want to get on your furniture because it will probably make your furniture greasier and greasier until you can’t take it anymore and have to throw it out
Looking out a window? Hah! I keep all my windows covered with heavy blankets year round and use artificial light day and night. The thermal advantages of keeping windows insulated and covered, by retaining heat or coolness, heavily outweigh the the minimal cost of using artificial light, day-in, night out. My parents didn’t believe me for the longest time, till they realized my electric bill was a small fraction of theirs all year round. Now I live in a 200 year old, 3 story house. Much of it, never had any insulation in the walls either. Same deal. Wool blankets over the single pane windows, year round, relatively small electric bill, even while primarily heating with electric, in the great northeast.
UVA sucks!!! Washington & Lee rocks though. I am not at all bitter that I applied to UVA from out of state didn’t get in. Actually, I completely forget I applied there until after the UVA sucks joke popped into my head. I didn’t apply to law school there though. But no joke, W&L was a great law school experience. That was 25 years ago, but I am guessing applications may be down a bit the last few years…
I’ve seen stories about truck drivers that show more aging on the side of the face corresponding to the side of the vehicle they are on… Honestly, I’m of the philosophy that if I’m outside regularly, my body will make enough melanin to protect me. (for vacations and extended periods in the sun, wear sunscreen)
I take issue with this. There is much more to this issue than is covered in this article. In the interests of providing suitably nuanced advice, you need address the issue of Vitamin D deficiency in a separate article. Skin exposure to the sun is the principle way we obtain this vitamin and due to to our current aversion to the sun, whole sectors of the population are vitamin D deficient. Vitamin D is vital for the correct function of our immune systems and a lack inhibits our ability to mount a robust defence to many disorders than can kill. Sunburn is undoubtedly a bad thing, but we all need some regular exposure to sunlight (without sunscreen).
In the early days of my sun allergy, I always thought only direct sunlight would hurt me. But booooy, I was wrong. Once I was at school and there was a window behind me. I didn’t thought that the UV could reach my skin, so when it started to burn, I freaked out because I didn’t know what would have caused that. And this is how I learned that a lot of windows do not protect my skin from UV.
But isn’t the sun in spring-/autumn-/winter-time much lower all day anyway, so the light needs to take already a longer way through the atmosphere and is already much weaker than during summer-time and therefore the time we need to spend in order to get sun-burned (overwhelm our body-cells’ repair-abilities), is already a lot longer? And what’s with the Vitamin-D-Production, that UV-Light is supposed to stimulate in certain skin-cells? And, of course, the mood-enhancements from the sheer brightness-levels (Light-Temperature) during the day, that affect the Circadian Rhythm, too. So, I think the risk of getting burned and develop skin-cancer needs to really be mitigated depending on the time spent outside packed in warm(ing) clothes and the amount of skin surface subjected to the sun’s light- and electromagnetic spectrum… Proportionality matters as always and knowing our skin’s limits (which differs depending on the amount of melanin it contains) when it comes to UV-radiation “mitigation”…
I don’t know what doctors recommend this nonsense. In Summer my skin always gets more healthy with sun exposure. The not exposed parts don’t. People did get out without sunscreen for our whole existence. And now everybody worries about such tiny risks. This is just over the top caution. Skin can tan and adapt, if you let it get used to the radiation. Food choice and your level of physical exercise are far more important when it comes to health. When you are not as white as ghost like a redhead and live in a high latitude, there is not much to worry at all. If you are in a region closer to the equator and especially in Australia, sure sunscreen is important.
This is just like the behaviour of nuclear radiation: alpha particles are big and heavy and they crash into everything immediately – you can stop them with a piece of paper and they can’t make it past the very outer layer of your skin; beta particles don’t have as much energy individually, but since they’re small enough to penetrate into your skin they’re more harmful and can cause radiation burns; and most gamma radiation will go right through you without interacting at all, but that does mean that if you get a big enough dose to cause damage, that damage can happen anywhere in your body including vital organs.
Or just do what I do and not open the curtains ever. Then your arms won’t be covered in oily greasy sun screen and won’t stick to your cheap imitation leather computer chair. I only have to put up with the discomfort of oily greasy sunscreen on my skin when I’m abroad on holiday actually spending a lot of time outside and when I’m not on holiday, I spend most of my time going to indoors places like work, home, the gym, the mall, and the cinema so I just don’t bother with sunscreen. It’s so dull and overcast and the days are so short here for half the year, you probably should be taking vitamin D supplements even if you work outside here…
“so, dermatologists, other doctors and other health agencies have started recommending you wear sunscreen, even if you are indoors”. I recommend you drink chocolate milk, find these dermatologists, other doctors and health agencies, and hold them down while you dangle a really sticky loogie over their face, to remind them what happens when nerds get cocky.
