Topic: Nitric Oxide

UVA light exposure on the skin stimulates the production of nitric oxide (NO), a vasodilator essential for cardiovascular health and the prevention of hypertension. The body expresses Neuropsin, a specific UVA light detector, in the skin, eyes, and testes, where it influences testosterone production and local circadian regulation. Avoiding UVA through excessive sunscreen use or clothing may contribute to NO deficiency and related conditions like erectile dysfunction.

Jolie explains the specific physiological benefits of sunlight, such as the release of nitric oxide to lower blood pressure and the use of cholesterol to synthesize Vitamin D. She warns that artificial blue light at night keeps cortisol levels elevated and suppresses melatonin. This hormonal disruption contributes to chronic conditions like diabetes, high blood pressure, and obesity.

Heart attacks are described as a result of a nervous system imbalance that forces heart cells to burn carbohydrates instead of fat, leading to a buildup of lactic acid. This process causes cellular swelling and tissue necrosis, independent of arterial clots, as evidenced by the work of researcher Giorgio Baroldi.
