What is the connection between vitamin D and sunlight?

natural production of vitamin D in the skin that is carried out by radiation from the Sun is the primary connection between vitamin D and sunlight. Vitamin D production is one of the primary skin functions, along with more apparent features such as feeling and insulation. When the skin is affected by ultraviolet light from the Sun, it creates a substance that the body can convert to vitamin D. In areas with sufficiently strong sunlight, regular exposure to the sun rays can produce enough vitamin D to meet the requirements of the body. Due to the connection between vitamin D and sunlight, this vitamin is often informally called the sunlight vitamin.

Vitamin D synthesis in the skin begins when a modified type of cholesterol naturally present in skin cells is exposed to sunlight. Specifically, the molecule is exposed to the invisible type of light, known as ultraviolet B (UVB), which converts it into a substance called cholecalciferol. Cholecalciferol is then transmitted by the bloodstream to the liver and iceVIN, where it is further modified to become an active form of vitamin D, also known as calcitriol. The relationship between vitamin D and sunlight helps the body to perform a number of important functions. The most important of these is maintenance of healthy bones and teeth.

various geographical places can affect the relationship between vitamin D and sunlight. In northern latitudes, the weaker and less frequent sun reduces the opportunities to produce vitamin D precursor. Also, because such a climate is colder, people are more likely to wear heavy clothes and spend more time in the interior, which further reduces the time spent in the sun.

pollution and clouds can also reduce the amount of ultraviolet light that reaches the ground surface. Yet, five to 15 minutes -day unprotected exposure to sunlight is likely to meet the need for vitamin most people D. The longer period of exposure to the sun rays increases RIGIko skin cancer. It also increases the age of the skin faster, increasing the occurrence of wrinkles and stains.

While environmental factors can disrupt the relationship between vitamin D and sunlight, this vitamin can also be obtained through food sources or supplements where it is absorbed in the intestine. Good sources of vitamin D food include cold water fish, egg yolks and fortified foods such as milk or breakfast cereals. Vitamin D can also be purchased as a supplement and is usually part of multivitamin formulas.
