When is the best time to get vitamin D from the sun in California?
Midday, especially during summer, is the best time to get sunlight. At noon, the sun is at its highest point, and its UVB rays are most intense. That means you need less time in the sun to make sufficient vitamin D ( 5 ). Many studies also show that the body is most efficient at making vitamin D at noon ( 6 , 7 ).
Do I need vitamin D if I live in California?
Your body needs vitamin D to absorb calcium. Calcium keeps your bones and muscles—including your heart—healthy and strong. People who do not get enough calcium and vitamin D throughout life have an increased chance of having thin and brittle bones ( osteoporosis) in their later years.
Can vitamin D be delivered through direct sunlight?
How do we get vitamin D? Our body creates vitamin D from direct sunlight on our skin when we’re outdoors. From about late March/early April to the end of September, most people should be able to get all the vitamin D we need from sunlight.
How much vitamin D do you get from the sun in California?
Goodman says exposing 5 percent of a person’s uncovered body surface to the sun twice a week for 15 minutes will generate the equivalent of 400 IUs of vitamin D a day. Research also shows that fat tissue stores vitamin D during sunny days so that enough is released on cloudy or rainy days.
Does vitamin D cause dark spots?
Although vitamin D is essential for skin health, its primary role is the promotion of melanin formation, which may cause more skin darkening.
Does vitamin D tan your skin?
What does seem to be the general consensus though, is that whilst it’s probably unlikely that vitamin D supplements darken the skin, being exposed to sunlight helps us to manufacture vitamin D, and in this process, we may also get a tan.
Is vitamin D good for hair?
Share on Pinterest Vitamin D stimulates hair follicles, so a deficiency may lead to hair loss. There is some evidence that having a vitamin D deficiency does cause hair loss and other hair problems.

Is it possible to get vitamin D from the Sun?
If you are in your car or behind a glass window Vitamin D production isn’t possible. UVB rays have to strike your exposed skin to make Vitamin D creation possible. Sunscreen lotion also blocks the production of Vitamin D.

Is it possible to get vitamin D in the winter?
And follow your doctor’s advice. In North America (and anywhere in the northern hemisphere) during the winter, the farther north you are, the lower in the sky the sun is during the day. In fact, in much of North America it isn’t even possible to produce Vitamin D in the winter—even in the middle of the day when the sun is at its highest point.
How does the time of day affect vitamin D production?
The time of day (midday has the highest potential to stimulate Vitamin D production), altitude (higher altitudes increase production potential), and cloud cover and pollution (both decrease production potential) also impact the time it takes to produce Vitamin D.
