Staying indoors for a long time is not a wise choice, from time to time out of vacation to go outdoors in the sun is very beneficial to the health of the body.

The sun has these benefits:

Vitamin D is also known as the "sunshine vitamin", which can help the body to take in and absorb calcium and phosphorus, so that children's bones grow strong and sturdy, and prevent osteoporosis and rheumatoid arthritis in adults.

2. Prevent myopia

A study by the Australian National University pointed out that the lack of sunlight exposure may be one of the causes of myopia. More outdoor activities can help reduce the risk of myopia.

3. Relieve depression

The occurrence of depression may be related to three factors, including biological, psychological, and social factors, of which insufficient sun exposure belongs to the important biological factors. Experts believe that sunlight can promote the brain's neurotransmitter synthesis and secretion, so that people have a sense of pleasure, to alleviate depression has some help.

4. Enhance immunity

Georgetown University researchers found that sunlight can enhance immunity. Low-intensity blue light in the sunlight helps activate signaling channels, making immune cells T cells move quickly and stay alert to deal with germ invasion.

5. Sun exposure can prevent skin diseases

Proper exposure of the skin to ultraviolet light can effectively kill bacteria on the skin and increase the resistance of the skin.

6. Mediation of human life rhythm

Sunlight also has a certain role in mediating the human life rhythm and psychological aspects. Sun exposure can promote human blood circulation, enhance the body's metabolic ability, and regulate the central nervous system so that the body feels comfortable and stretched.

Notes on sunbathing

Sunbathing has so many benefits, but not excessive exposure to the sun, generally 3 to 4 times a week in the sun for 10 to 20 minutes of sunlight, you can meet the body's demand for the manufacture of Vitamin D. If you are sitting in the sun in the hot season, be sure to wear a sun hat.

Although the sun is good for physical and mental health, but should not choose the day just in the middle of the continuous three or two hours of exposure, otherwise, it may be heat stroke. In addition, too much exposure to the sun can easily turn moles into melanoma or skin cancer, and you should cover up the parts of moles when you are sunbathing.
