De ce ne trezim uneori cu câteva minute înainte să sune alarma. Explicația simplă

Waking up just before an alarm is often due to the body's internal clock, which anticipates wake-up times based on a consistent sleep schedule. The circadian rhythm, regulated by the suprachiasmatic nucleus in the brain, plays a crucial role in this process. As the usual wake-up time approaches, cortisol levels rise while melatonin decreases, preparing the body for waking. Factors like light exposure can also influence this timing. However, waking up too early can be problematic if it disrupts daily functioning, potentially requiring medical advice if it becomes frequent.
