Why is it that we feel guilty for taking naps? Ever been sound asleep during the daylight hours when a ringing phone jolts you out of your slumber? I have. And when my caller asks after hearing my groggy voice, "Were you sleeping?" I'm ever so quick to announce, "Sleeping? No, I'm not sleeping."

It's too bad naps are not more socially acceptable. Because they sure are beneficial.

"Napping should not be frowned upon at the office or make you feel guilty at home," says Dr. James B. Maas, psychologist and sleep expert at Cornell. "It should have the status of daily exercise."

I like how this guy thinks. Forget jump-starting our tired bodies with caffeine and sugar. These tactics don't work anyway. Instead, let's embrace the restorative nap. Some companies offer time -- and reclining chairs too -- so sleep-deprived employees can get a little shut-eye. And some self-employed folks are taking mini-siestas throughout their work days. These people have the right idea.

The 24-minute nap is what experts recommend. It improves alertness and performance, increases energy and brain activity, and if it takes place about eight hours after you wake in the morning and occurs at the same time each day, napping can do wonders for your health.

Really, it's OK.

Sweet dreams.
