We all smile when the sun comes out.
Sunlight can boost our moods and also help treat a lot of illnesses.
In fact, it’s not just planted that absorb and metabolize sunlight, human beings do too.
There may be a disadvantage to people with pale skin as too much exposure to the sun can lead to skin cancer.
However, according to research, the positive effects of the sun for our health outweigh the disadvantages.
Here are eight ways the sun is important to our health:
Prevents Heart Disease
According to a study by a British medical journal, people in the United Kingdom are likely to die of heart-related problems during the winter season due to lack of Vitamin D.
A compound in the sun called nitric oxide helps reduce blood pressure and heart-related problems once it is in contact with skin. This is according to Dr. Richard Weller, a senior lecturer in dermatology at the University of Edinburg.
These advantages far outweigh the risk of skin cancer.
Improves Brain Function
A study (https://www.scientificamerican.com/article/does-d-make-a-difference/) by Neurologist David Llewellyn of the University of Cambridge proved that Vitamin D from the sun improves brain functionality.
The study examined over 1700 men and women and assessed their Vitamin D levels.
This is what they noticed: those with lower Vitamin D levels performed poorly on mental tests than their counterparts who had higher Vitamin D levels.
Prevents Multiple Sclerosis
Multiple sclerosis is a serious disease which affects the central nervous system. In advanced stages, it leads to tremor and paralysis.
The cause of this disease is not yet identified but countries which are sunnier have lower cases of multiple sclerosis.
It has also been noted children who are exposed to Vitamin D while young have a lower risk of getting this disease.
Improves and Boosts Fertility
The sun drastically reduces the hormone that suppresses fertility. This hormone is known as melatonin.
There are higher chances that you will conceive during the summer period and not during the winter period.
Not only does it increase the chances of fertility but it also lengthens the fertility period. A study done in Turkey showed that women who are exposed to less than an hour of sunlight each day are likely to reach menopause earlier.
Builds Immune System
When exposed to sunlight, the white blood cells in the body are reproduced. These white blood cells are very important to fight against diseases and infections.
Gives You More Energy
Melatonin regulates sleep and helps you feel more lively and energetic. Being awoken by natural light, rather than an alarm clock, makes you feel more productive.
Here is how it works.
When the sun hits our eyes, the pineal gland and production of melatonin which helps us feel drowsy and induces sleep is shut down.
The message sent to the pineal gland in our brain helps you feel ready for the day and energizes you at the same time.
Heals Some Skin Disorders
According to this study (https://www.ncbi.nlm.nih.gov/pubmed/18755366), an exposure to sunlight for four weeks reduced the subjects’ symptoms of psoriasis.
However, this should be done under strict medical supervision to prevent the side effects of UV rays.
