Winter Sunlight and its Effects on Our Well-being – NBC Boston

As New England enters the late fall season and prepares for winter, we notice the days becoming shorter and the sun appearing lower in the sky. This shift in sunlight angle poses a challenge for individuals living in northern altitudes, particularly those residing in Boston, which is located at 42 degrees N, well above the 37th parallel.

During the winter months, the sun only rises 25 degrees above the horizon in December, compared to its 70-degree angle from the horizon during the summer months. This lack of direct sunlight between November and February can make it difficult for individuals to absorb enough vitamin D through their skin.

Vitamin D plays a crucial role in various bodily processes, including immune system support and brain function related to mental health. Inadequate levels of vitamin D can lead to Seasonal Affective Disorder (SAD) or seasonal depression, making it essential to maintain optimal levels during winter.

To address this deficiency, individuals residing in regions with limited sunlight can explore alternative sources of vitamin D, such as dietary supplements or vitamin D-rich foods. Additionally, consulting with healthcare professionals about taking vitamin D supplements may help maintain optimal levels and prevent potential health issues associated with low levels of vitamin D during winter.
