Why does our energy drop in the afternoon despite good sleep?

You may feel drowsy and experience a decline in concentration in the afternoon, even after getting a good night’s sleep. However, the cause is not necessarily related to your lunch; it may be part of the natural circadian rhythm that regulates the body’s activity throughout the day.

A report by the British newspaper “The Mirror,” based on research references, explains that alertness levels tend to dip in the mid-afternoon for many people, typically between 2 p.m. and 4 p.m., before rising again later in the day.

Research suggests that this dip can occur even without consuming a traditional lunch, reinforcing the role of the biological clock in this phenomenon.

Nevertheless, the quality of food, sleep, physical activity, and exposure to light can influence energy levels. Experts recommend that lunch be balanced, combining protein, fiber-rich carbohydrates, vegetables, and healthy fats.

Movement, exposure to light, and taking a short break can help restore energy, while a brief nap may improve alertness and performance for some individuals.
