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.

Simultaneously, physiological responses essential for stress adaptation are triggered in the body. Cardiovascular regulation, including changes in blood pressure and heart rate, is a critical stress response. Under stress, animals change their behavior, such as through "fight or flight" or "freezing" response.
