Ever wonder why you tend to feel more tired, down, and get sick more often in the winter? A top doctor provides a key reason: a seasonal drop in Vitamin D levels due to reduced sun exposure.
The expert explains that the winter months, with their shorter days and weaker sun, make it difficult for our bodies to produce adequate amounts of this crucial hormone. This seasonal deficiency has a direct impact on our well-being.
Vitamin D is a master regulator of both the immune system and mood. When levels dip in the winter, our immune defenses can weaken, making us more susceptible to colds and flu. Simultaneously, the drop can affect neurotransmitters in the brain, contributing to feelings of seasonal sadness or the “winter blues.”
While it’s difficult to get enough from the winter sun in many climates, understanding this connection is the first step. The symptoms are not “just in your head”; they have a physiological basis in this hormonal shift.
During these months, it’s especially important to maximize any sun you can get. The doctor’s advice to seek out midday sun when possible is still relevant. For those in colder climates, this is also the time when consulting a physician about a safe supplementation dose (typically 600-800 IU) becomes most important.
