In our daily life, basking in the sun seems to become a casual activity, most people take it for granted, and even some people avoid the sun.
First, the close link between sun exposure and bone health
Not getting enough sun can lead to weak bones because the ultraviolet rays in the sun cause the skin to produce vitamin D, which in turn helps the body absorb calcium and make bones stronger.
To be in the sun correctly, the time should be mastered, about 20 minutes a day, to avoid skin sunburn. The best time to bask in the sun is 6 a.m. to 10 p.m., 4 p.m. to 5 p.m., when the sun is mild, comfortable and pleasant, but also more conducive to calcium.
2. The curious connection between sunlight exposure and intellectual development
Sun exposure not only contributes to bone health, but also improves intelligence, which is especially important for children and the elderly.
Uv B in sunlight boosts the production of vitamin D, which in turn boosts levels of glutamate in the brain, which is closely linked to memory and learning.
Therefore, sun exposure helps enhance learning and memory, which is beneficial for both children and the elderly.
Third, the positive impact of sun exposure on mood
Moderate sunlight exposure can promote the release of serotonin in the brain, lifting a person's mood and helping to alleviate seasonal mood swings.
In addition, sunlight regulates the body clock and helps maintain normal sleep patterns.
However, excessive sun exposure can cause skin problems and even increase the risk of skin cancer, so it is important to pay attention to sun protection when in the sun.
Fourth, enhance immunity: the benefits of sun exposure can not be ignored
Vitamin D is an important nutrient produced by sunlight on the skin and is able to activate T cells in the immune system, boosting the body's immunity against pathogens.
In addition, sunlight increases the activity of natural killer cells, which respond quickly and destroy abnormal cells in the body, such as cancer cells.
5. The magic link between sunlight and cardiovascular health
The ultraviolet rays in sunlight promote the production of nitric oxide in the skin, which helps to lower blood pressure and improve blood flow, which is beneficial for cardiovascular health.
The potential link between sun exposure and life extension
Sun exposure helps boost vitamin D intake, reduces the risk of chronic disease and may help extend life.
In conclusion, sun exposure not only contributes to bone health, intellectual development, mood regulation, immune enhancement, cardiovascular health, but may also help prolong life.
