De ce ne este mai greu să adormim atunci când știm că trebuie să ne trezim devreme. Ce se întâmplă în creier

Anticipating an important day can lead to difficulty falling asleep due to anticipatory anxiety, which heightens alertness instead of promoting rest. This phenomenon occurs not only before stressful events but also before exciting ones, as the mind becomes preoccupied with thoughts about the upcoming day. The pressure of limited sleep time can exacerbate this issue, making it harder to relax. Additionally, treating sleep as a task to accomplish can increase anxiety, while checking the clock repeatedly reinforces the urgency of falling asleep. Adjusting bedtime suddenly may also disrupt the body's natural sleep rhythm.
