According to the World Health Organization, up to 80% of the sun's UV rays can still penetrate light cloud cover. This means that even on overcast days, there is still an opportunity for your skin to produce vitamin D from sunlight exposure. However, the amount produced and the efficiency of this process are affected by several factors, including the type and thickness of the clouds.

Studies indicate that even on an overcast day, a significant portion of UV rays can penetrate cloud cover. This surprising fact means that yes, you can still get vitamin D on a rainy day, but the process is far less efficient than on a clear day.

According to the US National Weather Service and Environmental Protection Agency, up to 89% of UV rays can penetrate thin cloud cover. This surprising fact reveals that even when the sky is overcast, it is still possible to get vitamin D from the sun. However, the amount produced and the time required are both affected by the density of the clouds and other key factors.

According to the U.S. Environmental Protection Agency, thin or broken cloud cover can still allow up to 90% of UV rays to pass through. But do you still get vitamin D when it's cloudy? The surprising answer is yes, but the efficiency and amount of UVB radiation reaching your skin are significantly reduced depending on the cloud type and thickness.

Even on a cloudy day, where 90% of UV rays can still pass through, your body's ability to produce vitamin D from sunlight is significantly reduced. This often leads people to question: **can you get vitamin D if it's not sunny**? The good news is that there are several reliable ways to maintain healthy vitamin D levels without relying on direct sunlight.

According to the U.S. National Weather Service and Environmental Protection Agency, even with overcast conditions, about 32% of UV rays can still penetrate. This statistic directly answers the question, "Can I get vitamin D on a cloudy day?" but the full picture is more complex and depends on a variety of influencing factors.

Approximately 1 billion people worldwide have a vitamin D deficiency, a condition often linked to insufficient sunlight exposure. So, can you get vitamin D when there is no sun out? The answer is yes, and understanding the alternative sources is crucial for your health.
