HOW SLEEP LOSS AFFECTS YOU You know firsthand that sleep loss is not just a “night-time” problem. Its impact can extend far into the next day, limiting how well you can function physically and mentally. The table below lists just a few ways that a sleep deficit becomes a “daytime" deficit. And while there is clearly no substitute for a good night’s sleep, there are ways to increase your chances of staying alert. Are you sure you’re not tired? Most of us are extremely poor judges of our own fatigue levels. Tips for staying alert If you’re dealing with a sleep deficit, these tips may help get you through a sluggish day: Eat breakfast. You’ll need the energy it provides. Avoid a “sugar rush.” You might get a lift from eating candies, cakes, and other high-sugar foods, but you’ll crash pretty quickly. Instead, eat meals and snacks that combine complex carbohydrates and protein. Move around. Stimulate your body by taking a brief walk outside or around the office; you’ll feel more alert. Vary your activities. Don’t focus on the same task for long periods of time. Get chilly. A surge of cold air might perk you up. Depending on the season, you could turn on the air conditioning, open a window, or take a brisk walk outside. Do Our Sleep IQ Test>>
