Part 11/14:

• Migration and mismatch: Rapid movement of populations away from their ancestral environments has created mismatches, leading to deficiencies in some groups (e.g., Black Americans at higher risk of vitamin D deficiency) and damage in others (e.g., increased skin cancer risk among light-skinned populations due to overexposure).

Strategies for Reintegrating Sunlight into Our Lives

• Moderate sun exposure: Short periods (about 10-15 minutes) during peak UVB times can suffice, especially for lighter skin tones.
