Sunlight is important for keeping the body healthy. Being in the sun produces vitamin D in the body, which helps strengthen bones and muscles as well as maintain a normal immune system. However, excess sunlight can be harmful to the skin and eyes. Therefore, experts recommend taking it in moderation rather than avoiding the sun completely.
Vitamin D is produced in the skin when exposed to the sun’s ultraviolet rays. However, not everyone produces this vitamin at the same rate. Its amount varies depending on age, skin color, geographical location and season. According to Professor Rebecca Mason of the University of Sydney, vitamin D does not require prolonged exposure to the sun. A short period of sunlight may be sufficient in many cases. Since darker skin has more natural protection, it may take a little longer to produce vitamin D.
Sunlight is not only important for producing vitamin D, but also for sleep and mental well-being. Natural light, especially in the morning, helps regulate the body’s biological clock, or circadian rhythm. Not getting enough light can lead to sleep disturbances as well as problems like depression or anxiety.
However, there is no specific time limit for how long you should be in the sun every day. This is because the level of ultraviolet rays or UV index of the sun changes with the region, season and weather. Therefore, it is important to consider not only the time but also the intensity of the sun. People with fair or sensitive skin should be especially careful. If the sun is strong, they should cover their skin and use sunscreen as needed.
The body cannot produce much vitamin D in excess sunlight. On the contrary, prolonged exposure to sunlight can increase the risk of sunburn, premature aging, and skin cancer. The eyes can also be damaged. Therefore, it is better to use protective sunglasses when going out in strong sunlight.
On the other hand, vitamin D deficiency can occur even if you stay away from the sun for a long time. Especially in children, there is a risk of weakening bones due to this effect. However, it is possible to meet the need for vitamin D from food and supplements as needed, in addition to sunlight. However, additional vitamin D supplements should not be taken without the advice of a doctor, because excessive doses can damage the kidneys.
Harvard Medical School professor Joan Manson also warned against prolonged sun exposure. Experts advise not to avoid the sun altogether, but to get as much sunlight as needed and to protect your skin and eyes from the harmful effects of ultraviolet rays.
