It'll Give You a Stiff Upper Lip
Surplus sleep is more effective than painkillers—a surprise discovery by researchers at the Sleep Disorders and Research Center at Henry Ford Hospital. When drowsy people were allowed to sleep for up to 10 hours, four nights in a row, they were 25 percent less sensitive to pain (more effective than 60 milligrams of codeine!) and more alert, compared with those who slept their normal hours. The lesson: While any sleep helps decrease pain sensitivity, an extra one to two hours for several nights before a surgery or procedure may steel you even more.
