“NSDR involves listening to a guided meditation using breathing techniques and focusing the spotlight of attention on specific sensations and body parts in turn,” explains Hallissey. “It can be performed seated or lying down. Long extended exhales are used to activate the rest and digest system to induce a state of deep relaxation in both body and mind.”

If you’re new to the practice, the experts recommend following these steps:

Find a comfortable space to relax, where you know you won’t be disturbed.
Make sure you’re warm, comfortable and wearing loose clothing.
Turn off your devices and any electronics in the room so you won’t be distracted, and remove all stimulants.
While you will feel deeply relaxed, try not to fall asleep. It’s OK if you do, but you’ll gain more from the process if you’re lucid.
Now you’re ready to follow a guided meditation or breathwork practice; there are a variety of apps and tutorials available online, so get to know which ones work for you.
And relax.
