The Two-Minute Sleep Exercise

You stretch out and find a posture that is comfortable for you. Then start relaxing the body from top to bottom.

Face: Relaxing the face is particularly essential as facial expressions are closely linked to emotions. Close your eyes and then relax the jaw muscles, tongue and mouth one after the other.

Upper body and arms: One after the other, relax the shoulders, the neck, then the arms and hands.

Legs: First relax your right thigh, then calf and foot. Then relax the left leg in the same way.
