This is the viral moment a personal trainer shares a “mind-blowing” technique for falling asleep in only two minutes at any time and in any place.

Justin Agustin, age not disclosed, explained the method, which he says is often used in the military, in a video shared on TikTok on 19th January.

In the video, which has notched up almost 5 million views, Justin explains: “Sleep for a soldier is crucial… Even on the battlefield, when the environment is extremely uncomfortable and there’s a lot of noise happening.

“Now according to my research, this was developed mainly for fighter pilots who need 100 percent of their reflexes and focus, which we all know decreases with the lack of sleep.”

He explained the technique as follows: “First, you need to calm your body and systematically relax and shut down each part of your body from head to toe, literally.

“Start by relaxing the muscles in your forehead. Relax your eyes, your cheeks, your jaw and focus on your breathing.

“Now go down to your neck and your shoulders. Make sure your shoulders are not tensed up. Drop them as low as you can and keep your arms loose to your side, including your hands and fingers.”

He then said to imagine a warm sensation travelling down from your head to your fingertips.

He added: “Now take a deep breath and slowly exhale, relaxing your chest, your stomach down to your thighs, knees, legs and feet.

“Again, imagine this warm sensation going down from your heart all the way to your toes.

“To do this, think of two scenarios. One, you’re lying in a canoe on a calm lake with nothing but a clear blue sky above you. Two, you’re lying in a black velvet hammock in a pitch black room.”

In case the person starts getting distracted or cannot control their thoughts, then, according to Justin, they need to spend 10 seconds repeating the words “don’t think”.

Justin concluded: “So that’s the technique, you’re supposed to practice every night for six weeks.”
