It is common, especially when you’re new to meditation, to fall asleep. Always meditate sitting up, and if you fall asleep, consider it well-needed rest. With practice, you’ll benefit from the deep, rejuvenating rest meditation offers, without nodding off. If you continue to fall asleep every time you sit down to meditate, you probably need to consider whether or not you’re getting good quality sleep and enough of it. Adequate sleep is crucial for optimum health.
