Comparative study of medicinal values and negative effects of sunlight

Sunlight is not a much appreciated natural element. Mothers are always cautious that their children are not exposed to too much sunlight. But are we aware that sunlight has quite a lot of medical benefits? In fact, some of the benefits are applicable to children. Find out more from this article.


Women, especially teenage girls fear too much exposure in sunlight. It is due to the reason that over exposure in sunlight causes sunburns, redness of skin and dark spots. There are many more bad effects of over exposure in sunlight. All such effects are clinically tested and proven. But what about the positive impact of sunlight. If you bask yourself in sunlight before noon, there are a lot of health benefits of that. Read on to find out more about that.

Effects of overexposure in sunlight

  • Overexposure in sunlight leads to sunburns and redness of skin. This redness will eventually lead to a dark patch over the skin.
  • In this fast working lifestyle people can't afford to stay at home and avoid sun exposure. A lot of labors who work under prolonged sun rays run a risk of skin cancer.
  • Before cancer can strikes in, people working under overexposure of sunlight also run under the risk of heart disease and stroke. Sun a stroke is also called sunstroke.
  • As I already mentioned, mothers always warn their children of the sun's rays and call them inside the house if they tend to play after 12 noon. This is because children don't have a strong immune system. They complain of severe headache after prolonged exposure in the sun. Children can develop migraine at a very small age due to strong exposure in ultraviolet rays.
  • Lastly, children can have a tendency to vomit whenever they come under excess exposure to sun rays.

Medicinal benefits of sunlight

  1. Optimum basking in sunlight helps in increasing the serotonin level in the body. Serotonin secretion helps in proper brain functioning. Lack of proper serotonin secretion causes poor brain development and brain diseases like dementia.
  2. If you let your infant child bask in sunlight for even half an hour, their bones develop well. Infants gain vitamin D from sunlight. But here I would like to reinstate what our mothers have said. Keep your infant in sunlight until before noon. When noon struck in the concentration of ultraviolet rays increase and it is very harmful for your child.
  3. If you are an asthmatic patient, then your doctor must have suggested you to sit in sunlight in the wee hours of morning. Although sunlight has anti-asthmatic ingredients, it will not remove this evil from your body completely. But, it highly reduces the harmful effects of asthma in the body.
  4. As sunlight has immense amount of vitamin D, it helps in improving teeth health.
  5. Although the strong ultraviolet rays of the sunlight cause skin cancer, it is good for curing other cancers. Patients suffering from ovarian cancer or prostrate cancer can take the help of mild sunlight for improving their health. Research has shown the good effects of sunlight during the early morning hours for such cancer patients.
  6. Believe it or not sunlight can cure pimples. Pimples grow from pollution and the bacteria evolving out of pollution. Exposure to sunlight kills bacteria.
  7. In fact, just like an anti-bacterial soap, sunlight has a good effect against killing the bacterial growth in the body. It is due to this reason infants are kept in sunlight for a while.
  8. You must have heard from your grandmas that during the monsoon children catch diseases easily.What is the reason behind this? The reason is that during the monsoon the amount of sunlight received by the children is very less. This leads to the increasing effect of virus. Hence they fall into quite a lot of diseases. During the summer, sunlight can be received in its optimum level. Therefore, the breeding of viruses of influenza, cold is restricted to a great extent during this time. Hence children remain healthy in summer.


So now you see that contrary to the popular belief, sunlight has a lot of positive effects. After reading this article you must be surprised to know many unknown facts about sunlight. Especially, many of us usually know or associate sunlight with cancer risks. But how many of us knew that mild sunlight has such anti-carcinogenic properties? So what are you waiting for? Open your windows, go to the balcony and bask in this boon from the God.

1. Most Indians are protected from the ill effects of cancer-causing UV rays because our bodies produce ‘melanin’ a protective pigment that combats its effects. The incidence of skin cancer is more in light-skinned people, who do not produce enough melanin. Melanin is the body’s natural defence against the harmful effects of the sun. Using sunscreen is a good way to fight the sun’s harmful rays.

2. “Over exposure of sunlight…risk of heart disease and stroke”. This is the first time I am seeing sunlight being mentioned as a cause for heart disease and stroke. Is this bit of information based on any studies? Request the author to cite a reference please. I do not think there is any association between heart disease and stroke. These are serious medical conditions and have to do with arteries and valves etcetera.

3. Stroke and sunstroke are different medical conditions. Never heard of ‘sun a stroke’. Sunstroke is also called heatstroke.

4. It is not just children, but everyone should avoid exposure to the sun between noon and around four in the evening because the sun is the sharpest during this period.

5. Vitamin D is essential for all ages, and hence exposure to early morning sun and the setting sun is advised for people of all ages.

6. Sunlight does not have “immense amount of vitamin D”. The body converts sunlight into vitamin D.

7. Sunlight curing pimples is a myth. Exposure to the sun in fact accelerates breakouts.

I came across this article, which talks about the relation of excess exposure to sunlight possibly leading to strokes or a heart attack: (refer to the opening sentence). Search results will also bring up other sources of this possibility.

I read the article, beyond the opening sentence. I must add here that the opening line is misleading. To be understood, the article must be read in its entirety. I am putting things into perspective here –

1. The opening sentence does not corroborate any study. It is an introduction, the author’s interpretation of what they understood. It is not what the research mentions
2. The study is done on Danes – Denmark doesn’t get too much sun, and people there rely on supplements to meet their body’s requirement
3. The article does not mention the professor as having referred to the sun or too much sun as being the cause of deaths. The professor refers to vitamin D as a supplement
4. I quote the professor - "These are very important results, because there is such great focus on eating vitamin D. We should use this information to ask ourselves whether or not we should continue to eat vitamins and nutritional supplements as if they were sweets. You shouldn't simply up the dose to feel better. We should only consume such vitamins in close coordination with our GP."
5. The research is clearly relevant to the intake of supplements
6. Did I miss something?

I want to add here that vitamin A is excellent for our skin and eyes, but too much of it, in its synthetic variant, can cause mental disorders and severely harm the growth of foetus, even in mothers who take the supplement a few years before they get pregnant. Studies warn us against vitamin A supplement, but not against eating carrots or vitamin A rich foods.

A good number of our people toil in the sun – we still have manual labour working the fields, laying roads etcetera. Africa being on the Equator receives excessive sunlight. People are exposed to sun round the year. There should be a dramatic increase in cardiovascular deaths in our villages and on our roads and in the African continent.

My research led me to some very interesting studies –
1. “The lowest rates of heart disease are found in the sun-drenched Mediterranean coast and in southern versus northern European countries” Southern Europe gets more sun! (
3. This article links exposure to sunlight to lowering of blood pressure and prevention against cardiovascular diseases. (
These are independent reports, and there plenty more similar studies.
