☀️ Vitamin D: The Winter Deficiency No One Feels—Until They Do
Vitamin D plays a critical role in bone health, muscle function, immune response, and nervous system regulation. Yet during winter months, reduced sunlight exposure makes deficiency increasingly common—especially in northern climates.
Low vitamin D levels have been associated with increased muscle tension, slower recovery, joint discomfort, and decreased neuromuscular efficiency. When levels are insufficient, the body’s ability to adapt to physical stress—training, work posture, or winter sports—can be compromised.
Supplementation can be a useful tool during low-sun months, but vitamin D works best as part of a bigger picture: proper movement, spinal mobility, sleep, and nervous system balance.
Sunlight builds it.
Movement uses it.
Alignment helps the body respond to it.
Winter health isn’t about one fix—it’s about supporting the systems that keep you resilient.
