Lack of sunlight is as harmful as smoking.

Sunlight seems to have become a "phobia" for modern people because of its harmful warnings. However, this is an essential element in life because it not only provides vitamin D but also helps people live longer and healthier.

In addition, sunlight also helps prevent many diseases such as obesity, cardiovascular disease, stroke, asthma, multiple sclerosis...

The human body produces vitamin D through sun exposure. This vitamin helps strengthen bones and teeth and prevents intestinal diseases.

In addition, the latest research also shows that healthy sunlight has many other benefits. For example, the body will produce nitric oxide to help protect the cardiovascular system and the happy hormone serotonin.

Sunbathing properly has many health benefits. Illustration.

1. Lack of sunlight is as harmful as smoking

A 20-year study of 30,000 women found that excessive sun avoidance was as bad as smoking. 1.5 out of 100 women who died in the past 20 years died from UV rays, compared with 3 out of 100 women who avoided the sun completely.

People who have the habit of sunbathing significantly reduce the risk of death from cardiovascular disease and cancer-related diseases.

2. Older people need more sunlight

Older adults who lack sunlight have lower blood levels of vitamin D and are less active outdoors. Sun exposure lowers blood pressure and reduces the risk of stroke and heart attack because the skin releases nitric oxide into the blood, which lowers blood pressure and causes blood vessels to dilate.

3. Sunlight helps reduce inflammation

Research shows that in winter the activity of inflammatory genes increases in the immune system to fight disease, and in summer the activity of anti-inflammatory genes increases.

Chronic inflammation is linked to many diseases, including heart disease, diabetes, and cancer. Sunlight can help the body regulate its natural inflammatory response. There is a correlation between sun exposure and diseases like multiple sclerosis and atherosclerosis.

4. Sunlight helps fight obesity

Scientists have discovered that sunlight also helps people become slimmer and healthier. People who are exposed to sunlight can reduce the development of obesity and symptoms of type 2 diabetes. This is the effect of nitric oxide in the blood, making insulin unable to "run rampant", helping to reduce diabetes.

Sun exposure also helps reduce the risk of stroke. People often feel brighter when exposed to sunlight, which regulates the body's levels of the sleep-inducing hormone melatonin. This hormone can also cause depression, Alzheimer's disease and Parkinson's disease.

5. Helps children's eyes better

Lack of sunlight has obvious consequences for children. Children who do not spend enough time playing outside have a significantly increased risk of nearsightedness. The neurotransmitter dopamine inhibits the excessive growth of the eyeball that causes nearsightedness. Sunlight causes retinol to release dopamine.

Sunscreen should be used properly to avoid losing the benefits of sunlight.

6. Helps male ability

Sunlight can also increase male libido. The male hormone testosterone increases in August, decreases in winter, and drops significantly in the month with less sunlight.

7. Helps you live longer

Although excessive sun exposure is dangerous and we should avoid the sun between 11am and 3pm, people who get reasonable sun exposure live longer.

Avoiding the sun completely can increase the risk of heart disease. We should also use sunscreen properly so as not to completely lose the benefits of sunlight.
