Why does meditation help you fall asleep at all
The dominant model of insomnia is not tiredness deficit, it is hyperarousal. The body stays in a low grade alert state, heart rate a little high, thoughts scanning for problems, and sleep cannot start on top of that. Meditation works on exactly this layer. A slow breath and attention placed in the body shift the balance toward the branch of the nervous system that handles rest and digestion. Nothing gets switched off, and that matters: the moment you try to force thinking to stop, you add effort, and effort is arousal. The practical goal for the night is different and much kinder. You are not chasing sleep. You are lowering the volume until sleep can walk in on its own, and lying quietly without struggle already counts as rest.

How do you do a body scan in bed, step by step
Lie on your back or your side, arms loose, and let the mattress hold your weight. Bring attention to the soles of your feet and stay there for three or four breaths. Notice temperature, contact, pressure, whatever is there, including nothing. Move up slowly: ankles, calves, knees, thighs, hips, belly, chest, hands, arms, shoulders, throat, jaw, eyes, forehead. Give each area a few breaths. Where you find holding, especially jaw, tongue and the space between the eyebrows, let the exhale carry it out. You will lose track and start planning tomorrow. That is not failure, it is the practice: notice, return to the last place you remember, continue. Most people never reach the forehead awake, which is the point. If you do reach it, start again at the feet.
