If you need a quick burst of stamina – forget the energy drink. Try this instead...

The next time you feel the urge to yawn – don’t stifle it!

That simple yawn is a valuable boost of energy and stamina. Yawning can improve mental alertness, cool the brain and help us transition – even between time zones. A yawn first thing in the morning can help you wake up faster - and one before bed can help you feel sleepy.

Patt Lind-Kyle, author of “Heal Your Mind, Rewire Your Brain,” says we don’t have to sit around and wait for that yawn. The easiest way to trigger a yawn is to fake one. After 2 or 3 tries, you’ll be yawning like a pro. Just be sure you’re in a yawn-friendly environment before trying it – because it really works.
