Sunlight is the primary way for people to get vitamin D. In fact, the UV rays in the sun stimulate the skin to produce vitamin D. But that's not all.

We all know that exposure to a lot of ultraviolet (UV) from the sun can cause skin cancer and premature aging. However, that is no reason to deny the benefits of sunlight. This natural light source not only provides energy, but also offers many important health benefits.

Let's see how sunlight works in the following article.

20 reasons why you should expose yourself to the sun daily

1. Good for mental health

Sunlight has the ability to boost the production of serotonin - a chemical transmitter that plays a role in stabilizing mood. Therefore, designing a living space with plenty of natural light will be very good for the homeowner's mental health. In addition, many studies show that serotonin also works to treat depression and anxiety.

2. Prevent cancer

In fact, excessive sun exposure can cause skin cancer. However, if you are exposed to this light in moderation, it will bring many benefits. Including the effect of preventing some types of sun cancer.

According to one study, people living in areas with little sunlight during the day are more likely to develop cancers such as Hodgkin's lymphoma, colon cancer, and ovarian cancer.

3. Strengthen the immune system

When the body is exposed to the sun, the number of white blood cells (lymphocytes) tends to increase. These cells play an important role in protecting the body against infections and disease.

4. Sunlight helps keep the bones strong

The UV rays in the sun promote vitamin D production, stimulating calcium absorption. This helps in enhancing bone health. Children who don't get enough vitamin D can develop rickets. Meanwhile, the elderly who lack vitamin D from the sun are susceptible to osteoporosis and osteoarthritis.

5. Heal skin diseases

Light therapy using UV radiation is an extremely effective treatment for a number of skin conditions such as psoriasis, eczema, jaundice and acne.

6. Improved vision

Sun exposure has been shown to reduce myopia in children. Studies have also shown that nearsightedness often develops in people who regularly stay indoors and rarely participate in outdoor activities.

7. Enhance brain function 

Vitamin D not only promotes bone health, but also plays an important role in maintaining brain function. Studies have shown that sunlight can help stimulate the growth of cells in the hippocampus - the part of the anterior brain responsible for the formation of organelles and keep memories.

8. Reduce the amount of cholesterol in the blood

Sunlight has the ability to convert blood cholesterol levels into steroid hormones and other hormones needed for reproduction. If the body doesn't absorb enough sunlight, the reverse process will take place. This causes substances to be converted to cholesterol, increasing cholesterol in the blood.

9. Stimulate growth in children

Exposure to the sun for a sufficient amount of time (15–30 minutes from 6 to 8 a.m.) will help stimulate baby's growth and height development, especially in the first years of life. Reports show that the amount of sunshine a baby's body absorbs in the first few months of life has an effect on a baby's height as an adult.

10. Lower blood pressure

When sunlight hits the skin, a compound called nitric oxide is released into the bloodstream. This compound helps to lower blood pressure. This will reduce your risk of heart attack and stroke.

11. Sunlight helps improve sleep quality

Sunlight has the ability to affect the production of the hormone melatonin. This hormone plays an important role in the regulation of sleep and circadian rhythm of the body.

When sunlight hits your eyes, a message is sent to your brain to stop the production of the hormone melatonin. This helps you stay awake to study and work during the day.

When it gets dark, signals are sent to the brain to initiate the production of melatonin, making it easier to fall asleep and sleep better.

12. Helps keep your teeth strong

Vitamin D created during sunlight exposure promotes calcium production - the main building block of both teeth and bones. Not only that, but this vitamin has also been shown to help control gum disease by encouraging healthy and anti-inflammatory growth of the gums.

13. Prevent multiple sclerosis

People with a family history of multiple sclerosis should develop a healthy, nutritious diet. In particular, they need to ensure they get the full amount of vitamin D their body needs. A healthy immune system will help you increase the ability to prevent multiple sclerosis.

14. Increase the concentration of oxygen in the blood

Sunlight provides energy and vitamin D to the body's cells. This helps to speed up the signaling to retain or burn fat. According to research, the sun can help promote weight loss up to 70% faster.

16. Improve atherosclerosis condition

Sunlight penetrates deep into the skin tissues, helping to clean the blood vessels. Many studies done in Europe have demonstrated that people with atherosclerosis show signs of improvement after they are exposed to sunlight.

17. Sunlight helps relieve asthma symptoms

According to experts, spending time in the sun is the best way to treat asthma. This is because vitamin D can help reduce the symptoms of the disease. Likewise, studies have also shown that low vitamin D levels can make asthma symptoms worse.

18. Helps relieve muscle aches and pains
