IS Ultraviolet LIGHT Good for Your Body? Sunlight is a Treasure for Us!
Nowadays, most people sit inside the office all day long, not always contact with the sun, and have little physical activity. If things go on like this, it will be really bad for our health. Almost all living things grow by the sun, and human cannot live without the sunlight!
Ultraviolet LIGHT SOURCES OF VITAMIN D
Medical research has shown that everyone should be exposed to sunlight for at least 20-30 minutes per day. An appropriate amount of ultraviolet light can promote calcium absorption and prevent osteoporosis and rickets. Sun exposure is beneficial to increase the blood circulation of human skin and internal organs and improve the function of hematopoietic, especially in the prevention and treatment of rickets for children and osteoporosis for adults.
As the sunlight is the main source of vitamin D for the body, so sun exposure can help the body obtain it. Vitamin D is also called “sunshine vitamin”. The source of vitamin D3 contained in human skin is produced by obtaining ultraviolet rays from the sun and converted into vitamin D. Vitamin D can help the body to absorb calcium and phosphorus, make sure the children’s have stronger bones, prevent infant rickets and rickets, and prevent adult’s osteoporosis and rheumatoid arthritis.
ULTRAVIOLET LIGHT IS BACTERIA KILLER
Sun exposure can also prevent some skin diseases. Appropriate exposure of the skin to ultraviolet rays can effectively kill bacteria on the skin and increase the skin’s resistance. Sun exposure can also enhance the body’s immune function and increase the vitality of phagocytes. The ultraviolet rays in the sun have a strong bactericidal ability. Generally, bacteria and certain viruses will be killed if they are exposed to the sun for half an hour or several hours.
Daylight also plays a role in mediating the rhythm of human life and psychology. The infrared rays in the sun can penetrate the skin to the subcutaneous tissues, play a role in warming, dilate blood vessels, promote blood circulation and metabolism of the whole body, regulate the central nervous system, and make the human body feel comfortable. The ultraviolet rays in the sun can also stimulate the bone marrow to produce red blood cells, improve hematopoietic function, and prevent anemia.
Sunlight, air, water and movement have always been regarded as the four major sources of human existence. Sun exposure can prevent cancer. The American Association for Cancer Research also confirmed this conclusion. This is because the skin can only produce vitamin D after receiving ultraviolet radiation, and vitamin D can eliminate the blood environment formed by tumors and prevent colorectal cancer and prostate cancer. Some studies in the United States even believes that there is no nutrient that can be comparable to vitamin D in the prevention and treatment of cancer.
ENOUGH IS ENOUGH FOR ULTRAVIOLET LIGHT
Of course, too much of sun exposure can also cause damage to the body. There are two periods of the day that are best for sunbathing. The first segment is from 6 am to 10 am. At this time, infrared rays occupy the peak and the ultraviolet rays are low, which makes people feel warm and soft, which can promote blood circulation and remove blood stasis.
The second segment is 4-5 pm, at this time The A beam in the positive ultraviolet rays has the upper hand, which can promote the absorption of calcium and phosphorus in the intestine, which is beneficial to strengthen the physical fitness and promote the normal calcification of bones. Regardless of the season, between 10 a.m. and 4 p.m., especially between 12 noon and 4 p.m., it’s best not to spend a long time in the sun, because at this time, the ultraviolet rays in the sun are the B beam prevailing, and it will Damage to the skin.
WHAT SHOULD PREPARE BEFORE A SUN EXPOSURE
It is best to wear red clothing when basking in the sun, white clothing is the second choice, and black is taboo. Infants and young children have delicate skin, and the sun exposure time should be controlled within 30 minutes. Drink plenty of water and rub some baby moisturizer after the sun exposure.
If the baby is too young to be exposed to the outdoors directly, it is generally 3-4 weeks after birth before the newborn can be carried outside to bask, and the initial time should be short, only part of the exposure, and then slowly increase the time and extend the scope. Outdoors, do not let the newborn blow the air for too long, or it will be easy to catch a cold. Do not irradiate the head and face directly.
You can put it in the shade or wear a hat. People who are prone to allergies should avoid sun exposure. The best way to prevent skin allergies is to reduce contact and try to protect themselves when going out. People who have had solar dermatitis and seasonal dermatitis in the past should also avoid sun exposure as much as possible, and avoid using alkaline cosmetics and soaps.
