Circadian rhythm may influence how well medications work and how much they might harm you

All living organisms on Earth are exposed to a 24-hour day-night cycle. This cycle is the reason why people rest during the darkness of night and are active during the light of day. Consequently, all human body functions also follow this daily rhythm, and the timing of behaviors like exercise or food intake can significantly influence your health. For example, eating at night can lead to weight gain over time because while daytime food intake is used for activities, food intake at night leads to increased fat storage because the body expects to be at rest.
