Progressive muscle relaxation is a technique that's meant to reduce physical tension and break up the obsessive thoughts that are preventing you from falling asleep.
The simple technique involves tensing the muscles all over your body, one by one, and then relaxing them again.
While there hasn't been a lot of scientific investigation into it, an older study found that self-proclaimed insomniacs were able to reduce the time it took to fall asleep by engaging in 20 minutes of progressive muscle relaxation each day.
Researchers from another study that monitored burn patients who were having trouble falling asleep found that progressive muscle relaxation could reduce anxiety and improve sleep quality.
Next time you're lying in bed awake, start at the top of your body and tense each muscle group and then let it relax.
Keep going down your whole body until you reach the muscles in your feet. While it may feel awkward at first, eventually you may be able to fall asleep more quickly.
