Benefits of the sun for humans: Does sitting in the sun have health benefits?

 The sun provides light and heat to Earth and contributes to the survival of life. Sun exposure may also provide many health benefits.


Why is the sun good for your body?


The benefits of the sun for humans include the following

1- Strengthening the immune system

Exposure to sunlight enhances the production of white blood cells, which increases the health of the immune system and reduces the possibility of harmful bacteria attacking the body and causing it to develop many diseases.

2- Longevity

People with more early morning sunlight exposure have been shown to live longer, healthier lives and can delay menopause in women.

3- Strengthening bones

Exposure to sunlight in the morning provides vitamin D, which strengthens bones and prevents osteoporosis.


This vitamin protects the body from several diseases, including heart disease, diabetes, and tooth decay.

4- Reducing weight gain

Sunlight reduces the body's levels of cortisol, a hormone that causes appetite.


5- Improving sleep quality

Exposure to sunlight increases the secretion of the hormone melatonin in the body, which has a positive effect on the psychological state and increases relaxation.


Exposure to sunlight also increases the secretion of the hormone serotonin, which brings a feeling of well-being and reduces the possibility of depression and psychological problems.


The negative effects of the sun on the body

The sun can damage the body in the following ways:

1- Increased risk to eyesight

Many people do not realize how dangerous sunlight is for eye health:


Cataracts: Cataracts, where the clear lens of the eye becomes cloudy, causing blurred vision and darkening of the front of the eye, can develop after prolonged exposure to harmful sunlight.

Macular degeneration: A disease caused by damage to the retina, which can lead to poor vision and even loss of vision.

*Eye burns: Sunlight can affect the eyes in the same way they affect the skin, causing burns and inflammation of the cornea, also known as “snow blindness.”

2- Increased acne scarring.

Sunlight may help hide acne for short periods of time, but sun exposure at the wrong time or for long periods of time can leave acne scars over time.


For acne, it is best to avoid sun exposure as much as possible and use sunscreen and acne treatments.

3- The appearance of red spots and burns on the body.

Direct exposure to the sun at noon without using sunscreen causes red spots on the skin, unbearable burns, severe rashes, and blood vessels that cannot be erased.




4- Sunstroke

Heatstroke is caused by prolonged exposure to direct sunlight. It usually affects people who have to move around at work during the day and can cause headaches and fainting spells.


It also causes fatigue and distress and affects energy and mood.


5- Skin cancer

Sunlight accelerates skin aging and reduces the skin's immune system, which increases the risk of skin cancer and various cancers.
