What's the difference between the inductions in the sleep app?
The Tension Release induction is the original, default induction. The script in this induction guides you through a progression of tensing and relaxing parts of your body. This is a very effective and well studied approach to relieving tension and treating insomnia.
If you prefer a more passive induction, the new Relaxing Color induction uses mental imagery to help you relax.
You can select the induction in the Settings tab.
