Body melt: sink into the mattress

Heavy shoulders. Heavy arms. Let the mattress take all of your weight. Start at the top of your head and imagine a warm, slow heaviness, like honey, melting down until you are fully held.

What it is

A short guided heaviness practice of just under two minutes. The voice starts at the top of the head and pours a warm, slow weight down over the forehead, eyes, cheeks and jaw, then the shoulders, arms and hands, through the chest and belly, and out through the legs and feet. It ends with the simple idea that there is nothing left to hold up: the bed has you. Stars drift quietly overhead. This Short points to our 8-hour deep brown noise as the longer video to leave playing afterwards; the music under the voice here is a separate, original pad, not that brown-noise track.

How to use it for sleep

This one works best already lying down. Let each area get heavy as it is named, without trying to force anything to relax. When the voice ends, put the brown-noise video on and turn the phone face-down, or try the shorter sinking into the mattress Short if you want the same idea in under a minute. Keep the brightness low so the stars stay soft.

Best for

Physically tired but mentally busy nights, people who like sensations more than imagery, and anyone whose shoulders are still up by their ears at bedtime. For a thought-first alternative from this same set, set each thought adrift gives each worry a lantern.

Sound design note

Under the voice is an original, slow procedural pad made by SleepBetter, with no binaural tone, so it plays fine on a speaker. Keep the volume low.

Transcript

The full narration, as spoken. Pauses are left out.

Heavy shoulders. Heavy arms.
Let's let the mattress take all of your weight.
Start at the top of your head... and imagine a warm, slow heaviness, like honey, melting down.
It flows over your forehead... softening every line.
Down over your eyes... your cheeks... your jaw.
It pours over your shoulders... and they sink. Lower... and lower.
Down your arms... into your elbows... your wrists... all the way to your fingertips. Heavy. Warm.
Now it flows through your chest... and your breathing slows.
Down into your belly... your hips... sinking deeper into the bed.
Through your legs... your knees... your calves... and out through your feet.
You are heavy... warm... and fully held.
There is nothing to hold up anymore. The bed has you.
Just sink... and sink... and let go into sleep.
