Space out

You might think multitasking will help you tackle your to-do list faster, but taking a few minutes to drift into space can actually do wonders for your energy level, according to Dr Jacob Teitelbaum, author of The Fatigue and Fibromyalgia Solution. “Shifting into a place that feels good through spacing out will then get you back in touch with your intuition, and you will be much more efficient,” he says. So take a quick pause to daydream, chat up a friend or co-worker, or make a cup of tea that matches your mood.
Go for a quick walk

Step away from the vending machine and take a stroll around the block instead. California State University scientists found that a brisk 10-minute walk increases your energy levels and sustains it for two hours. For an even bigger boost, take the stairs. A study published in the Physiology & Behavior, found that stair walking provided more energy than low dose caffeine in sleep-deprived young women.

Eat an energising snack

Look for a healthy bite that combines protein with complex carbohydrates, such as a hard-boiled egg with whole wheat toast, cheese on multi-grain crackers, or an apple with peanut butter. “Complex carbohydrates get digested more slowly, still giving you rapid energy by raising sugar, but not high enough to cause the rebound effect,” says Dr Teitelbaum. “The protein then maintains blood sugar over several hours, making this an excellent combination for energy.”
