Why do I feel sleepy or fall asleep when I meditate?
Short Answer
Meditation sleepiness occurs because relaxation activates the parasympathetic nervous system, which naturally promotes rest, especially when the body is already fatigued.
Why This Matters
The meditative state closely resembles the brain's preparation for sleep, with reduced cortical activity and increased alpha waves. This physiological similarity causes the nervous system to interpret meditation as a cue for sleep, particularly when practitioners are already tired or practicing in comfortable positions. The phenomenon demonstrates the powerful connection between relaxation techniques and the body's natural sleep mechanisms.
Where This Changes
Sleepiness typically decreases with regular practice as the brain learns to distinguish between meditative awareness and sleep preparation. Alert postures and meditation during naturally wakeful hours reduce this tendency.
