Some of you may wonder why I haven’t posted much over the past week. It’s simple–I caught a touch of the flu and have needed to rest.

As a massage therapist, wellness coach, and small business owner, I work a lot of hours. And in my work, I come in contact with many people every day. Some of my clients see me when they are sick or are getting over an illness but are still contagious. Being self employed, I don’t get paid sick time.  Therefore, I do all I can to avoid catching colds and flues. However, there are still times when my immune system can’t handle the fight and an infection or flu bug gets me. Luckily, living healthy keeps me well most of the time and helps me get over most illnesses relatively quickly. In those times when I do get sick, one of the principle methods I use to get over an illness is one you can’t buy in a store: it’s rest.

The definition of rest, according to education.yahoo.com here is:

  1. Cessation of work, exertion, or activity.
  2. Peace, ease, or refreshment resulting from sleep or the cessation of an activity.
  3. Sleep or quiet relaxation.
  4. The repose of death: eternal rest.
  5. Relief or freedom from disquiet or disturbance.
  6. Mental or emotional tranquillity.
  7. Termination or absence of motion.

Looking through this list, how many times the past week have you been able to achieve the definitions cited in point 1, 2, 3 or 5 above? When I think of rest, I don’t only think of sleep. I also think of relaxing, having quiet time to contemplate my navel or meditate or watch clouds pass overhead. Resting to me is a time to let the worldly concerns go and just relax my mind and body. Which is tough to do in today’s fast paced culture. But rest is ever more important in today’s world. Most people do not even get the required 7-8 hours of sleep. Then they spend the day working on computers, meeting with other people, traveling and commuting, going to the gym or home to spend time with family. In all the hours we spend working and meeting outside obligations, rest is often confined to the hours of sleep we can sandwich into  the rest of our lives. But studies show that rest is an important tool in our wellness arsenal. Napping is a common event in many cultures (just not in the U.S.!). Read more from my post on Daytime Naps here. And meditation is an effective way to rest our minds as well.

NASA is currently doing a study on how bed rest effects human subjects in space travel. Read more about the study here.

Harvard Health Publications has the latest word on napping and your health. Read the article below from Harvard Health Letter to find out why short daytime naps may be good for business’ bottom line!

Napping may not be such a no-no

Research is showing that the daytime snooze may have benefits and not interfere with nighttime sleep.

At work, if you get caught napping, it could get you into trouble or, more mildly, sully your reputation for diligence. In studies, naps have been linked to ill health, although usually as a consequence, not a cause. And in sleep recommendations, naps have taken a back seat — or been cast as a threat to nighttime sleep.

But lately, naps have been shedding some of their bad-for-you image. Researchers are finding benefits. A few employers have become accommodating of the quick snooze. And some research suggests that instead of fretting about napping more as we get older, we should plan on adding daytime sleep to our schedule as a way to make up for the normal, age-related decay in the quality of our nighttime sleep.

Getting over the hump

Naps, of course, can be an antidote to daytime sleepiness, and we get sleepy during the day for a wide variety of reasons. There is, in fact, a biological clock located in a cluster of cells in the hypothalamus of the brain. Those cells orchestrate the circadian (that is, daily) ups and downs of many physiological processes (body temperature, blood pressure, secretion of digestive juices), including sleep and wakefulness. As you might expect, the usual circadian pattern is wakefulness during the day followed by gradually increasing sleepiness in the evening, but it’s also common to have a little “hump” of midafternoon sleepiness programmed into the circadian schedule. An afternoon nap is one way to accommodate that hump.

In 2008, British researchers reported results of a study that compared getting more nighttime sleep, taking a nap, and using caffeine as ways to cope with the afternoon hump. The nap was the most effective.

Another factor in daytime sleepiness is the number of hours you’ve been awake. After about 16 consecutive hours without sleep, most of us will start to feel tired. Ideally, this homeostatic sleep drive, as it is called, is in sync with the one set by our circadian rhythm, so they’re mutually reinforcing. But if you work a night shift, or have problems sleeping at night, your 16-hour allotment of wakefulness may begin — and end — earlier, which can set you up for grogginess in the late afternoon or early evening. A short nap won’t completely reset the timer, but it can buy you some time before the grogginess sets in again.

How to take a good nap

Keep it short. The 20- to 30-minute nap may be the ideal pick-me-up. Even just napping for a few minutes has benefits. Longer naps can lead to sleep inertia — the post-sleep grogginess that can be difficult to shake off.

Find a dark, quiet, cool place. You don’t want to waste a lot of time getting to sleep. Reducing light and noise helps most people nod off faster. Cool temperatures are helpful, too.

Plan on it. Waiting till daytime sleepiness gets so bad that you have to take a nap can be uncomfortable and dangerous if, say, you’re driving. A regular nap time may also help you get to sleep faster and wake up quicker.

Time your caffeine. Caffeine takes some time to kick in. A small Japanese study published several years ago found that drinking a caffeinated beverage and then taking a short nap immediately afterward was the most restful combination because the sleep occurred just before the caffeine took effect. We’re not so sure about that approach — the mere suggestion of caffeine, in the form of coffee taste or smell, wakes us up. Regardless of the exact timing, you need to coordinate caffeine intake with your nap.

Don’t feel guilty! The well-timed nap can make you more productive at work and at home.

On the job

Since 2000 or so, researchers at Harvard and elsewhere have conducted dozens of experiments that have shown that sleep improves learning, memory, and creative thinking. In many cases, the edifying sleep has come in the form of a nap. For example, several studies have shown that if people are asked to memorize something — say, a list of words — and then take a nap, they’ll remember more of it than they would have if they hadn’t taken the nap. Even catnaps of six minutes (not counting the five minutes it takes to fall asleep on average) have been shown to make a difference in how well people retain information.

Robert Stickgold, a Harvard sleep researcher, says napping makes people more effective problem solvers. His research group has shown that taking a nap seems to help people separate important information from extraneous details. If the nap includes REM sleep — the phase during which dreaming occurs — people become better at making connections between seemingly unrelated words.

Stickgold says his and others’ findings argue for employer policies that actively encourage napping, especially in today’s knowledge-based economy. Some companies have set up nap rooms, and Google has “nap pods” that block out light and sound.

Understandably, employers are concerned about abuse: employees catching up on sleep they should be getting on their own time. But there may be a place for “strategic napping,” especially among people who work a night shift. Results from a New Zealand study published in 2009 showed that air traffic controllers working the night shift scored better on tests of alertness and performance if they took advantage of a planned nap period of 40 minutes. Researchers in the Harvard Division of Sleep Medicine are working with fire departments to improve sleep policies. One of their recommendations is that firefighters on the night shift take a nap in the late afternoon before their shift starts.
