Research highlights the crucial role of circadian rhythms in regulating the immune system and overall health. Macrophages, a type of immune cell, operate more effectively in the morning when the body faces challenges from injuries or infections. Light exposure dramatically impacts this rhythm, with morning sunlight enhancing alertness, while nighttime exposure can disrupt sleep and increase health risks, especially in older adults. Meal timing also affects organ functions, with earlier meals linked to better metabolic regulation. Consistently maintaining sleep schedules and healthy routines can reinforce these rhythms and promote well-being.
Research shows that circadian rhythms significantly influence immune system function and inflammation, with macrophages acting more actively during morning hours.
Exposure to light at night is particularly harmful for older adults, raising their risk of obesity, hypertension, and diabetes by disrupting their circadian rhythms.
