As a health educator at GreenLite Medicine, many of my discussions with our patients address the more “obvious” aspects of weight management such as dietary choices, physical activity, and behavioral triggers when it comes to food consumption. 

All of these issues are very important, but there is another one that is often overlooked and is just as crucial in weight management and overall health — sleep. 

An estimated 50-70 million Americans suffer from some form of insomnia, with the affliction most common among the obese population and those with hypertension (high blood pressure), anxiety, and depression. Numerous studies have linked sleep loss with weight gain, as sleep duration may be an important regulator of body weight and metabolism. Lack of sleep disrupts the body’s balance of hormones such as insulin, leptin, and ghrelin. Leptin is responsible for regulating energy intake and expenditure, and acts on receptors in the brain to suppress appetite. Ghrelin, on the other hand, is known as the “hunger hormone,” playing a role in promoting meal initiation and lowering feelings of satiety after meals. A recent study conducted at the Howard Hughes Medical Institute at Stanford University concluded that people with short sleep cycles (less than 6 hours a night) showed increased levels of ghrelin and reduced levels of leptin in their morning blood samples. Translation? It’s a recipe for weight gain.

Insufficient sleep can also affect body weight on a less clinical level. When we’re deprived of sleep, we often feel lethargic and are too tired for exercise. Being tired can also make us feel depressed and moody, making us more susceptible to increased carbohydrate cravings and using food as a tool for cheering us up.

Sleep medication may be one solution to severe or chronic sleep problems, but here are a few organic approaches to achieving a good night’s sleep:

  1. Reduce caffeine. Over 55% of the U.S. adult population drinks coffee daily. Aside from coffee, caffeine is found in some teas, soft drinks, chocolate, and certain over-the-counter medications. Caffeine is a central nervous system stimulant which takes effect, in part, by allowing the adrenal glands to release adrenaline into the bloodstream. A moderate amount of caffeine will make you feel more alert and energetic, but excessive amounts can result in anxiety, agitation, and restlessness, ultimately disrupting sleep patterns. Additionally, your ability to excrete caffeine decreases with age, according to Dr. Arthur Spielman, a leading scientist in neurology and sleep disorders. So as we get older, we may need to cut back on our caffeine intake, especially later in the day.
  2. Increase exercise. A study published in the journal Sleep Medicine reports that as little as 20-40 minutes of moderate aerobic activity 4 times a week improved sleep quality in the participants. Researchers state that the participants, after maintaining a regular exercise schedule for 16 weeks, raised their status from “poor” to “good” sleeper, and also reported increased energy, fewer depressive symptoms, and less drowsiness and lethargy in the daytime. Just remember not to exercise too close to bedtime, as this may increase body temperature, heart rate, and endorphins, leading to poor sleep quality.
  3. Herbal teas. A warm cup of tea before bed can do wonders for relaxing the body and calming the mind. There are many blended “sleep” formula teas on the market, but common herbs to promote tranquility are chamomile, valerian, lemon balm, and passion flower. Find one that appeals to you and incorporate it into your nighttime ritual.
  4. Melatonin. Melatonin is a hormone produced in the brain that regulates the body’s circadian rhythm, or your sleep-wake cycle. Studies have shown that melatonin, taken as a supplement, decreases the time it takes to fall asleep, increases feelings of sleepiness, and may enhance sleep duration. Taking 0.1 to 0.3 milligrams of melatonin before bedtime can help induce a good night’s sleep.
  5. Relaxation techniques. There are many practiced relaxation techniques that can help calm the body and mind before bedtime. These range from meditation to deep breathing to guided imagery. There are a wealth of CD’s and downloads available on this subject, as well as short courses offered at many schools and medical centers. When practiced regularly, relaxation techniques not only help promote better sleep, but often reduce daily stress and anxiety levels.
  6. Sleep environment. Ultimately, you can’t sleep well if you’re not comfortable. Achieving the best quality sleep might be as easy as adjusting your sleeping environment. Make sure your mattress is supportive; if it has dips, lumps, or if you wake up stiff and sore, it might be time to replace it. Over or under-stuffed pillows may affect breathing patterns, and unclean sheets may harbor allergens. Reduce or eliminate as much noise and light as possible, and turn the tv and lights off when you get into bed. Set your climate control to a pleasant temperature.

Hopefully, employing one or a few of these tips will help you push the “reset” button on your sleep quality. After all, as W.C. Fields said, “The best cure for insomnia is to get a lot of sleep.”

  • […] As a nation, we’re out of control and most of us know it, but we can’t seem to stop the trend towards obesity. As we’ve moved from a hunter gatherer, farmer herder society to one with modern conveniences and an industrialized food source, we’ve disconnected ourselves from our own bodies. We’ve developed some unhealthy habits that are now generational—eating enormous portions, lots of processed, high-sugared foods, little movement or exercise, and not enough time in sweet slumber.
