Does Sunlight Through Glass Provide Vitamin D?

Q. Does sunlight through window glass provide vitamin D?

A. Sunlight doesn’t actually “provide” you with vitamin D. Rather, your body produces vitamin D when skin can be exposed to the sun’s ultraviolet rays, which trigger vitamin D synthesis. The liver as well as kidneys convert This kind of biologically inert form of vitamin D into biologically active forms the body can use to promote calcium absorption as well as bone health.

although sunlight consists of both ultraviolet A, or UVA, which penetrates deep within the skin layers as well as can cause premature aging; as well as ultraviolet B, or UVB, which causes the redness of sunburn. which’s the UVB rays which trigger the synthesis of vitamin D.

Many people can derive the vitamin D which their bodies need through direct exposure to sunlight during the summer months. As little as 10 minutes a day of sun exposure can be typically adequate. although for many, particularly those living in northern climes, production of vitamin D will be inadequate during the winter months.

as well as you can’t get adequate UVB exposure sitting indoors or in a car. Virtually all commercial as well as automobile glass blocks UVB rays. As a result, you will not be able to enhance your vitamin D levels by sitting in front of a sunny window, though much of the UVA radiation will penetrate the glass as well as may be harmful.
