Struggling to get to sleep at night is something every one of us has experienced.
Daily stresses take their toll and despite advice, it can be extremely difficult to put down your mobile an hour before bedtime.
But according to recent reports there is a technique that could help you nod off in under two minutes – and its tried and tested by the Army.
A book titled Relax and Win: Championship Performance features a secret US military method that can help anyone get to sleep in just 120 seconds.
It was originally published in 1981 but the method has resurfaced in recent days after being published online.
The technique is said to have a 96% success rate after six weeks of practice and was reportedly developed to eliminate mistakes made by pilots because of tiredness.
A survey in 2011 found that a third of people in the UK are severely sleep deprived.
Insomnia can be caused by stress, anxiety or depression with alcohol, nicotine and caffeine also affecting sleep patterns.
Everyone needs different amounts of sleep but according to the NHS, adults should get between seven and nine hours a night.
Chronic lack of sleep has been linked to health problems including diabetes, heart disease and strokes.
So how does the technique work?
Relax the muscles in your face, including your tongue, jaw and the muscles around your eyes.
Drop your shoulders as low as theyll go before relaxing your upper and lower arm on one side, and then the other.
Breathe out, relax your chest and then, finally, relax your legs, starting with your thighs and moving to your lower legs.
Once youve relaxed your body for ten seconds, you must attempt to clear your mind of all thoughts.
There are three methods that may help with this – according to the book.
1. Picture yourself lying in a canoe on a calm lake with nothing but blue sky above you
2. Picture yourself snuggled in a black velvet hammock in a pitch-black room
3. Repeat the words dont think, dont think, dont think in your mind for ten seconds
