Studies show that chronic sleep loss can disrupt blood sugar levels and cause the body to produce less leptin, a hormone that curbs appetite, and more ghrelin, the hormone that stimulates hunger. Because of these physiological changes, you may be more likely to overeat when you skimp on sleep and the food you pick probably won't be either nutritious or a lasting source of energy. Tired people tend to be particularly drawn to sugars and other simple carbohydrates, because the body is looking for a quick pick-me-up. Sleep deprivation also tends to erode self-control, making you more likely to choose a brownie over carrot sticks. Here are some ways you can suppress daytime fogginess, and possibly get better sleep.
- An early morning walk will help you sync up your internal clock to the sun, avoiding an energy slump in the afternoon.
- A power nap of 20 to 30 minutes may help ward off fatigue. Try to take a siesta after lunch, when your energy levels are particularly low.
- Work on something interesting. Even tired people pay better attention to tasks they find mentally stimulating.
- Big meals and high-sugar foods can cause blood sugar to spike, then plummet, so every few hours eat a snack (about 100 calories), or try smaller meals (of no more than 400 calories) that contain complex carbohydrates, some protein, and a small amount of healthy fat. Try a handful of nuts or reduced-fat cheese and whole grain crackers at low-energy times of the day, typically, early morning and late afternoon.
