9 Energy Boosters

Get an Energy Boost From Drinking Fluids

Your body needs water to transport oxygen to your cells. Deprive yourself of sufficient liquids and you may feel tired or get headaches. While there’s no magic number for the amount of liquid to consume in a day, experts say you should try to drink at least four tall glasses of water or low-calorie beverages, such as Propel or Crystal Light.
 
Caffeine gets a bad rap, but used judiciously, it can give you a lift. The trouble is “many people drink too much in the morning, so their energy is bunched up early in the day, and they need more later to keep going,” says Weil. Try to limit yourself to one cup of coffee in the morning and, if you must and it doesn’t interfere with falling asleep at night, a half cup after lunch. Consider switching to green tea, which contains caffeine but also theanine, a calming substance that counteracts the jitters from caffeine.
