Summer sun fails to fix vitamin D gap in at risk groups

Article excerpt

Even during summer months, people in high-risk groups across England maintain persistently low vitamin D levels, contradicting the common assumption that warm-season sun exposure alone can restore their stores. The finding challenges public health messaging that has long relied on seasonal sunlight as a natural remedy for deficiency. Researchers tracked vitamin D concentrations year-round in vulnerable populations, likely including older adults, those with darker skin tones, and people with limited outdoor access, and found the shortfall doesn't disappear when the sun is strongest. The discovery suggests these groups need additional interventions beyond relying on seasonal variation to maintain adequate vitamin D, which plays a crucial role in bone health, immune function, and overall wellness.
