Unraveling the Significance of Circadian Rhythms for Health

Modern humans are experiencing more disturbances in biological rhythms than in human history. The biological rhythm of modern humans is assumed to be quite different from that of our ancestors in the past. This phenomenon is due to the disturbances in the biological rhythm caused by artificial light and the lifestyle patterns adopted by us. Therefore, it is crucial to investigate the influence of circadian rhythm disturbances on human health. Recently, several interesting papers have shown that circadian rhythms are important for human health; a recently published paper particularly requires attention [1]. Eating and sleeping are two essential behaviors that humans engage in, on a daily basis [2]. Caloric restriction is known as one of the ways to live a long life. Several studies and experiments have shown that eating less increases the lifespan of animals by reducing the rate of aging. Reducing calorie intake reduces weight, in addition to lowering blood pressure and inflammation levels, and also regulates blood sugar in a better manner [3]. Furthermore, another study added that along with the amount of food eaten, the timing at which it is eaten is also important for extending the life span. Acosta-Rodríguez et al. [1] reported that a four-year experiment on hundreds of mice showed that eating only during active hours of the day contributes to an increase in life expectancy. The researchers examined these mice by dividing them into six groups and used an automatic feeder to control the amount of food and meal times. One group allowed them to eat as much as they wanted, while the other five groups were given 30%–40% Unraveling the Significance of Circadian Rhythms for Health
