Active vitamin D can exert biological effects in multiple tissues and organs such as intestines, kidneys and bones, which can not only promote the absorption of calcium and phosphorus, but also directly adjust bone metabolism, and is an important basic preparation for the prevention and treatment of vitamin D deficiency rickets and osteoporosis in children.

Yes, humans need to be in the sun a lot.

As the saying goes, everything grows by the sun, and the healthy growth of human beings is inseparable from the sun, so human beings should ensure that they can effectively bask in the sun every day, which has a positive effect on promoting the balance of trace elements in the body and physical and mental health.

Do humans need to be in the sun a lot? What are the dangers of getting too much sun?

The bad of sun exposure, just a little sunlight every day is enough to meet our body's need for vitamin D, too much sun exposure can easily have adverse effects on **.

Exposure to the sun or exposure to the sun for too long can easily lead to various diseases caused by sun exposure, such as sunburn, polymorphic sun rash, etc., which will increase the chance of developing **cancer. Therefore, it is best to wear sunscreen or parasol with a high SPF when outdoors for a long time, wear a wide-brimmed hat, wear sunglasses, and wear long sleeves.

Overexposure to sunlight can cause acute and chronic inflammation and aging, and may also induce precancerous lesions and even cancer. Acute inflammation caused by prolonged exposure to sunlight and UVB in excess of the tolerable amount, leading to necrosis of epidermal cells. Phototoxicity:

**Acute or chronic sunburn itching reactions that occur after exposure to or ingestion of certain photosensitive substances and exposure to specific wavelengths (mainly UVB) for a certain period of time.

Wear yellow or green sunglasses. The best sunglasses to wear in the sun are yellow or green lenses. Sunglasses with yellow lenses filter 100% of UVA waves, allowing infrared light and 83% of visible light to pass through the lenses.

Sunglasses with green lenses filter 99% of UVA waves, and green is a natural calming agent that can keep you refreshed on hot days. It is recommended not to choose pink sunglasses when basking in the sun. Pink lenses only filter out 95% of UVA waves and some shorter wavelengths of visible light, making them only suitable for rainy days when UV rays are not as strong.

1. The sun feeds us human beings, and if there is no light and heat from the sun, then what awaits mankind is undoubtedly the fate of extinction. It is only because of the sun that plants can carry out photosynthesis and the synthesis of organic matter.

2. Plants will use sunlight to carry out photosynthesis, and photosynthesis will inhale carbon dioxide and expel oxygen. This alone brings life to humans and animals.

3. The heat of the sun will evaporate the water, and then the water vapor will form a cloud in the air, and when the water vapor of the cloud reaches a certain value, it will rain. This has many benefits for agriculture. Of course, it also indirectly benefits mankind.

4. Sunlight shining on the ** will dilate the subcutaneous blood vessels, increase the blood flow, increase the excretion and resistance of toxic substances, increase the secretion of saliva and gastric juice, strengthen gastrointestinal peristalsis, and promote appetite and digestion.

5. It can be ...... with solar energy, solar cars, and solar watchesThese save electricity, water, and the environment.

The sun feeds us human beings, and without the light and heat of the sun, humanity is undoubtedly doomed. Spending time in the sun can replenish the vitamin D needed by the body.

The sun has many benefits for the human body, specifically the following:

1. Prevention and treatment of ** disease: the medium wave ultraviolet rays contained in sunlight, ** appropriate irradiation, can enhance ** resistance, the more common psoriasis, eczema, can be alleviated by moderate sun irradiation.

2. Calcium supplementation: The human body and sunlight contact can promote the synthesis of vitamin D, which is conducive to the absorption of calcium and phosphorus, and is beneficial to the prevention and alleviation of osteoporosis and fractures, and also helps children's height growth.

3. Promote metabolism: The infrared rays in the sunlight can enter the subcutaneous tissue, play a warming role, speed up blood circulation, and increase metabolism, especially for pregnant women and other people who are inactive.
