Meditation can help with sleep—but it is not a substitute for sleep.
Especially in the evening, meditation can help you notice thoughts and tension without becoming increasingly caught up in them. For some people, mindfulness-based programmes can improve subjective sleep quality and difficulties associated with sleep problems.
The evidence is not conclusive, however. Results differ depending on the people, meditation programmes, and comparison treatments being studied. In the case of a genuine chronic sleep disorder, meditation is therefore not automatically the best treatment.1
And no matter how relaxed you feel after meditating, it cannot perform the biological functions of sleep.
