When you feel tired and sleepy, the logical reaction might be to reach for a cup of coffee. Caffeine is not always the best solution, however. Although it can provide a quick burst of energy, it will eventually cause you to crash and feel even more tired than before. Caffeine can also cause elevated heartbeat and other side effects for some people, especially if you have to drink several cups in order to stay awake. Reaching for the right food might be a healthier, more permanent solution.

Grains are a good source of energy. When you eat carbohydrates, your body converts them into energy. Whole grains break down slowly, so they provide a steady source of energy. Simple sugars, on the other hand, break down fast, so they provide a quick peak of energy, followed by a crash. When you crash, you’ll feel tired, sleepy and low in energy. To stay awake, reach for foods that provide a steady release of energy, such as brown rice, whole wheat, wild rice, barley, rye and oats.

Fruits provide a quick burst of energy, but they don’t elevate sugar as much as starches and simple sugars, so they’re an acceptable option. Cardiothoracic surgeon and author Dr. Mehmet Cengiz Oz recommends fruits such as pineapple as it contains vitamin C, which perks up the brain and will improve your chances of staying awake.

Proteins are a good source of steady, slow energy. Protein is a good source of tyrosine, an amino acid that boosts your energy levels. All animal products, including fish, meats, dairy and eggs are all good sources of tyrosine. Vegetarians can try tofu and legumes for protein.

Dehydration can make you feel tired and sleepy. To stay awake, drink at least eight glasses of water a day. Cut down on caffeine as it dehydrates, and instead focus on caffeine-free and sugar-free drinks, such as seltzer water, herbal teas and diet drinks. Try eating a small snack or meal every three to four hours rather than a couple of large meals a day. This will help steady your blood sugar and maintain your energy steady so that you stay awake and energized.
