High Latitude Adaptation

Meaning

High Latitude Adaptation refers to the complex physiological, behavioral, and genetic adjustments human populations exhibit when living in geographical regions far from the equator, which are characterized by extreme seasonal variations in light and temperature. These crucial adaptations include alterations in vitamin D metabolism, changes in skin pigmentation, and necessary modifications to the amplitude and timing of circadian hormone cycles. Understanding this adaptation is vital for managing health challenges like Seasonal Affective Disorder and optimizing vitamin D status in these low-light environments.
