Sunlight travels to Earth as a mixture of both visible and invisible rays, or waves. Long waves, like radio waves, are harmless to people. But shorter waves, like ultraviolet (UV) light, can cause problems. The longest of these UV rays that reach the Earth’s surface are called UVA rays. The shorter ones are called UVB rays.

Too much exposure to UVB rays can lead to sunburn. UVA rays can travel more deeply into the skin than UVB rays, but both can affect your skin’s health. When UV rays enter skin cells, they upset delicate processes that affect the skin’s growth and appearance.

The Dark Side of Sun Exposure

Our bodies were built to make good use of the sun. Sunlight helps keep our sleeping patterns on track so we can stay awake by day and sleep soundly at night. Getting too little sun, especially in winter months, can leave some people prone to a form of depression known as seasonal affective disorder. Sunlight also helps our skin make vitamin D, which is needed for normal bone function and health. Yet sunlight can also cause damage.

Sunlight travels to Earth as a mixture of both visible and invisible rays, or waves. Long waves, like radio waves, are harmless to people. But shorter waves, like ultraviolet (UV) light, can cause problems. The longest of these UV rays that reach the Earth's surface are called UVA rays. The shorter ones are called UVB rays.

Too much exposure to UVB rays can lead to sunburn. UVA rays can travel more deeply into the skin than UVB rays, but both can affect your skin's health. When UV rays enter skin cells, they upset delicate processes that affect the skin's growth and appearance.

Over time, exposure to these rays can make the skin less elastic. Skin may even become thickened and leathery, wrinkled, or thinned like tissue paper. "The more sun exposure you have, the earlier your skin ages," says Dr. Barnett S. Kramer, a cancer prevention expert at NIH.

Your skin does have ways to prevent or repair such damage. The outermost layer of skin constantly sheds dead skin cells and replaces them. You might have noticed this type of skin repair if you've ever had a bad sunburn. Your skin may peel, but it usually looks normal in a week or 2.

"When you're exposed to ultraviolet radiation, there's a repair process that goes on constantly in each one of your exposed cells," says Dr. Stephen I. Katz, director of NIH's National Institute of Arthritis and Musculoskeletal and Skin Diseases. Still, long-term damage to your skin can remain.

As you get older, it becomes harder for skin to repair itself. Over time, UV damage can take a toll on your skin and its underlying connective tissue. As a result, your skin may develop more wrinkles and lines.

Too much sun exposure can also raise your risk for skin cancer, the most common type of cancer in the United States. When UV light enters skin cells, it can harm the genetic material (called DNA) within.

DNA damage can cause changes to cells that make them rapidly grow and divide. This growth can lead to clumps of extra cells called a tumor, or lesion. These may be cancerous (malignant) or harmless (benign).

Skin cancer may first appear as a small spot on the skin. Some cancers reach deep into surrounding tissue. They may also spread from the skin to other organs of the body.

Each year, more than 2 million people are treated for 2 types of skin cancer: basal cell and squamous cell carcinoma. These cancers are seen in both older and younger people, and they're rarely life-threatening.

Melanoma is a less common but more serious type of skin cancer that's diagnosed in more than 68,000 Americans each year. Another 48,000 are diagnosed with an early form of the disease that involves only the top layer of skin. Melanomas arise from the cells that provide pigment (color) to the skin.

Your risk for melanoma is higher if members of your family have had skin cancer or if you've already had melanoma or other skin cancers. A major risk factor for melanoma is having a large number of moles, or having large flat moles with irregular shapes. Sunburns, especially during childhood, may also raise your risk for melanoma.

"If you've had skin cancers in the past, then you're at a particularly high risk for developing another skin cancer," Kramer says. "Over the long run, there is a high rate of new lesions developing."

"One of the major factors affecting skin health is genetics, which determines the pigment content of your skin. This affects how much protection you have from natural sunlight," explains Katz. Although darker-skinned people have a lower risk for sun-related damage and disease, people of all races and skin color can still get skin cancer.

"Certain genetic mutations contribute to melanoma onset in certain people. You find much less non-melanoma skin cancer in African Americans, people from the Middle East, or even Asians from the Near East," Katz says.

The best way to protect skin health and prevent skin cancer is to limit sun exposure. Avoid prolonged time in the sun, and choose to be in the shade rather than in direct sunlight. Wear protective clothing and sunglasses, and use sunscreen between 10 a.m. and 4 p.m. Sunscreen is especially important at that time, when the sun's rays are most intense.

"The time to really start sun protective behavior is not when you reach adulthood, but years before," Kramer says. "The message to parents is, now is the time to start protecting your child against skin damage from sun overexposure, when your child is developing sun exposure habits and when they have many more years of potential sun exposure ahead of them." Among other skin-protecting habits, teach children and teens to avoid the use of tanning beds.

Sunscreens come labeled with a sun protection factor (SPF), such as 15, 30, or 50. A sunscreen labeled SPF 15 means it will take you 15 times as long to get a sunburn as it would if you had no sunscreen on. A sunscreen labeled SPF 30 means it would take you 30 times as long to burn.

The effectiveness of sunscreens is affected by several factors. A sunscreen's active ingredients can break down over time, so be sure to check the expiration date on the container. The amount of sunscreen you use and how often you use it affects your protection from the sun. Perspiration and time spent in the water can also reduce sunscreen effectiveness.

Some people look to the sun as a source of vitamin D, but it takes just a brief time in the sun to do the trick. "You need very little exposure-something like 10 to 15 minutes a day to the backs of your hands, arms, and face-to get enough," Katz says.

Several factors-like cloudy days or having dark-colored skin-can reduce the amount of vitamin D your skin makes. But you can also get vitamin D from foods or dietary supplements. Check with your health care provider about whether you should be taking vitamin D supplements.

Limit time in the sun to protect your skin against early wrinkles, damage, and disease. "Being sun smart is a good thing," Katz says. And if you spot a suspicious mark on your skin, Kramer advises, be sure to get it checked out.

The Dark Side of Sun Exposure Our bodies were built to make good use of the sun. Sunlight helps keep our sleeping patterns on track so we can stay awake by day and sleep soundly at night. Getting too little sun, especially in winter months, can leave some people prone to a form of depression known as seasonal affective disorder.

# data[].attributes.body
One of the best (and easiest) ways to get vitamin D is by being outside. Our bodies produce vitamin D when exposed to sunlight—about 15 minutes in the sun a day is adequate if you’re fair skinned. And since Vitamin D helps your body maintain calcium and prevents brittle, thin, or misshapen bones, soaking in sun may be just what the doctor ordered.

# data[].attributes.attachment_link.readable_text
Scientifically, sunshine has a lot of benefits for our bodies. Here are seven great reasons to get outside and soak in the sun.

1. Improves your sleep

Your body creates a hormone called melatonin that is critical to helping you sleep. Because your body starts producing it when it's dark, you usually start to feel sleepy two hours after the sun sets, which is one of the reasons our bodies naturally stay up later in the summer.

Research indicates that an hour of natural light in the morning will help you sleep better. Sunshine regulates your circadian rhythm by telling your body when to increase and decrease your melatonin levels. So, the more daylight exposure you can get, the better your body will produce melatonin when it's time to go to sleep.

2. Reduces stress

Melatonin also lowers stress reactivity and being outside will help your body naturally regulate melatonin, which can help reduce your stress level. Additionally, because you're often doing something active when you're outside (walking, playing, etc.), that extra exercise also helps to lower stress.

3. Maintains strong bones

One of the best (and easiest) ways to get vitamin D is by being outside. Our bodies produce vitamin D when exposed to sunlight-about 15 minutes in the sun a day is adequate if you're fair skinned. And since Vitamin D helps your body maintain calcium and prevents brittle, thin, or misshapen bones, soaking in sun may be just what the doctor ordered.

4. Helps keep the weight off

Getting outside for 30 minutes sometime between 8 a.m. and noon has been linked to weight loss. There, of course, could be other factors to this, but it seems there's a connection between sunlight in the early morning and weight loss.

5. Strengthens your immune system

Vitamin D is also critical for your immune system, and with consistent exposure to sunlight, you can help strengthen it. A healthy immune system can help reduce the risk of illness, infections, some cancers, and mortality after surgery.

6. Fights off depression

It's not just in your head; there's a scientific reason being in the sunshine improves your mood. Sunshine boosts your body's level of serotonin, which is a chemical that improves your mood and helps you stay calm and focused. Increased exposure to natural light may help ease the symptoms of seasonal affective disorder--a change in mood that typically occurs in the fall and winter months when there are fewer hours of daylight.

7. Can give you a longer life

A study that followed 30,000 Swedish women revealed that those who spent more time in the sun lived six months to two years longer than those with less sun exposure. More research needs to be done in this area, but it's something scientists are continuing to study.

5 Effective Ways to Soothe Sunburns At Home

Of course, a little sunshine can go a long way (and too much is harmful for our skin). Depending on the shade of your skin, scientists estimate your body can produce vitamin D in about 5 to 30 minutes in the sun. If you're wearing sunscreen, you may not produce as much vitamin D. If you're outside for some much-needed vitamin D, don't expose bare skin longer than 5 to 30 minutes.

7 Health Benefits of Sunlight | Select Health

Er is bewezen dat de zon goed is voor de aanmaak van vitamine D, een vitamine die het lichaam helpt bij het aanmaken van calcium en het voorkomen van zwakke botten.

Daarnaast is er ook bewezen dat de zon goed is voor depressie. Men heeft het vaak over een winterdepressie en dergelijke. De zon helpt het lichaam met het aanmaken van serotonine, het geluk hormoon.

Toch is de zon niet geweldig voor mensen met weinig tot geen pigment. Ik ben zelf zo wit als sneeuw, heb veel moedervlekken en verband snel. Ik ben de perfecte kandidaat als het gaat om huidkanker of zonbeschadiging.

Vitamine D kun je bijnemen en voor de aanmaak van serotonine zijn ook vele andere oplossingen te vinden. Ik vraag me af waarvoor wij (als organisme) de zon eigenlijk nog nodig hebben? Wegen de nadelen in deze tijd nog wel op tegen de voordelen?

Humans get our energy from the food we eat, and all of that food is derived from the energy of the sun. So, we need the sun to survive. But do humans need direct exposure to sunlight to survive, not counting our food and heat sources?

A study published in the Archives of Internal Medicine, stated that humans need sunlight for vitamin D. The study shows that those with the lowest vitamin D levels have more than double the risk of dying from heart disease and other causes over an eight-year period compared with those with the highest levels of vitamin D.

Sunshine vitamin D may protect against a host of diseases, including heart disease, cancers, osteoporosis, prostate cancer and colon cancer. Sunlight vitamin D also has other health benefits, like protecting against depression, insomnia, and an overactive immune system. Submariners have gone without sunlight for periods exceeding 6-months, using vitamin D supplements.

It is unlikely, though, that an adult could die directly and exclusively from prolonged darkness. Most likely a person would become ill and die from a range of chronic diseases caused by lack of sunshine, such as diabetes, high blood pressure, and tuberculosis.

So, yes, I would say that humans need sunlight to survive. Maybe it’s no coincidence that there are over 5 billion entries on Google under the search, “the sun.”

Let’s talk about daily doses of Vitamin D. Supplements can greatly help to those who are severely deficient and wants to overcome it rapidly. Once a person overcomes deficiency, it’s better to not remain dependent on supplement entirely for rest of the life if he/she can get enough Vitamin D from food and sunlight. Natural sunlight is always the best to induce plenty amount of Vitamin D. Also, some of the positive effects of sunlight exposure can’t be replicated by supplements.

A truly sincere doctor, dietitian, nutritionist and therapist wouldn’t recommend to depend on supplement if a person is capable of getting sunlight regularly and most importantly - doesn’t have issues in converting sunlight induced Vitamin D into active form of vitamin D. Vitamin D produced through sunlight exposure stays longer inside body compared to its administration through supplements.

In mijn vorige bericht vroeg ik me af of we de zon nog wel nodig hebben. Online las ik veel over vitamine D en serotonine, maar dit kan je bijnemen of op andere manieren aanmaken.

Shit,balen. Ik was er van overtuigd dat we de zon niet meer nodig hebben. Het wordt toch sterk afgeraden om afhankelijk te zijn van vitamine D supplementen.

Toch kreeg ik van mijn onderzoek een nieuwe vraag. Hebben we ONZE zon nog wel nodig? Kunnen we onze zon controleren? We zijn afhankelijk van zonnebrand, kleding en pigment om ons te beschermen voor de zon, maar is hier niet een andere manier voor?

Ik kan mij herinneren dat in het artikel Sun and Skin werd benoemd dat 15 minuten zon op de handpalmen al voldoende zou zijn. Is er een manier dat ik mijzelf kan beschermen van de zon, maar toch zonlicht krijg op een veilige en controleerbare manier?
