Why Do We Fall Asleep When We Stay Still? The Explanation from the Programme "Realitatea medicală"

Why does drowsiness occur when we stay still for long periods? Is it simply fatigue, or is the body sending us a particular signal? The topic was discussed by Nicole Păcuraru on the programme "Realitatea medicală", where she explained the mechanisms behind this state and the circumstances in which it may actually indicate a health problem.

According to the explanations provided, drowsiness sets in more quickly when the body remains motionless, regardless of whether we are sitting at a desk or on the sofa. The lack of movement has a direct effect on energy levels: blood circulation slows slightly, and the amount of oxygen reaching the brain decreases. Furthermore, when it receives no stimuli, the brain remains in a state of reduced activity.

Movement, on the other hand — even minimal movement — has the opposite effect: it activates the nervous system and increases alertness. This is why simply standing up from a chair sometimes helps more than an extra cup of coffee.

The programme's conclusion is clear: the human body is not designed for prolonged immobility. Energy does not come from sitting still, but from movement.
