Our body’s physiological processes oscillate on a 24-hour cycle known as the circadian rhythm. Circadian rhythms in blood pressure and heart rate, among other functions, are crucial for cardiovascular health and preventing cardiovascular disease. In general, light exposure increases nighttime blood pressure and heart rate.

As we age, we have lower levels of nitric oxide (NO), leading to endothelial dysfunction , arterial stiffening, and a rise in blood pressure (hypertension) — three of the primary causes of cardiovascular disease. Some studies have shown the potential of NR in particular to reduce blood pressure and arterial stiffness.
