Can You actually Grow Taller in Your Sleep? The Science of Decompression

It's not just for teenagers. Spinal decompression during deep sleep can add up to an inch to your height. Here's exactly how it works.

The Gravity Problem

Gravity compresses your spine all day. By 9 PM, you are literally shorter than you were at 9 AM. The intervertebral discs lose fluid and shrink.

Rehydration & HGH

To regain that height (and potentially grow if your plates are open), two things must happen:

  1. Spinal Decompression: Lying flat allows discs to rehydrate.
  2. HGH Release: Growth Hormone thickens cartilage and bone density.
📏 The "Morning Inch"

Deep Delta sleep maximizes disc fluid uptake, making you measurably taller upon waking.

The SleepHack "Stretch"

By ensuring you remain in a paralyzed, deep sleep state for longer blocks of time, SleepHack prevents the tossing and turning that interrupts spinal rehydration. Wake up at your maximum potential height every day.
