Sunlight exposure boosts longevity, expert says

Dr Vassily Eliopoulos explains on Instagram that morning sunlight hitting the retina within 30 minutes of waking triggers the suprachiasmatic nucleus (master clock) to synchronize hormonal and metabolic processes.

Skipping morning sunlight causes circadian misalignment, driving insulin insensitivity, elevated inflammatory markers, and disrupted hormonal pulses.

Sunlight-driven UVB exposure synthesizes vitamin D, with insufficiency present in ~40% of adults linked to higher all-cause mortality, cardiovascular risk, immune dysfunction, and cognitive decline.

UVA light from sunlight triggers the release of nitric oxide via the skin, which supports cardiovascular health.

Dr Vass shares a protocol for sunlight exposure to help those who primarily stay indoors.
