Feeling Tired?…Skip the Coffee and Put Your Head in the Freezer

It's a tip from a recent book called "The Sleep Prescription".

If you’re feeling tired and need a boost this afternoon, don’t reach for that third cup of coffee. Instead, just stick your head in a freezer. It’s a tip from a recent book called “The Sleep Prescription”. It’s by a neuro-scientist at the University of California, San Francisco. He says yes, you could just have that extra cup of coffee, and the caffeine will wake you up. But, if it’s late in the day, it could also keep you up at night. Sticking your head in a freezer offers a more immediate boost of energy, and it won’t mess with your bedtime routine. The scientific reason is the “brief shock of cold activates your arousal system.” You can get the same effect from a quick walk, or focusing on a non-work-related task for ten minutes.
