1) GO OUTSIDE AND INTO THE SUNSHINE - Light deprivation is one reason that people feel tired. Research suggests that light stimulates brain chemicals that improve mood. For an extra boost, get your sunlight first thing in the morning.
2) LAUGH - Laughter's a proven stress-buster, but studies suggest laughing can boost energy levels too. (Feel free to use this as permission to go on YouTube for the next 30 minutes.)
3) GO FOR A QUICK WALK - Aside from the fact that moving throughout the day is beneficial in so many ways, one study found that even a ten-minute walk was enough to supply a feeling of energy and decreased tension.
4) TAKE A POWER NAP - Take a quick midday power nap. Studies show the optimal amount of sleep is 10 to 20 minutes to get through the day without throwing off the night's sleep.
5) EAT REGULARLY - The body needs fuel to function, and without it our energy levels can plummet. However, regular healthy meals and snacks can improve cognitive function. But keep in mind not sleeping enough can also cause us to eat when we're not actually hungry, so check in with that stomach before munching down.
6) LISTEN TO AN UPBEAT SONG - Hearing stimulating music gives an instant lift and is one of the quickest, most reliable ways to affect your mood and energy level. I’m always surprised by the effectiveness of this strategy.
7) STRETCH & BREATHE - Just a few desk stretches may be enough, but studies have suggested a little yoga could help to increase your energy and motivation. Deep and controlled breathing can also help. Nope, it's not just the key to resisting the urge to scream at that stupid driver. Deep "yoga breathing" from the diaphragm gets your blood moving and your body awakened which can help increase your energy all day long.
8) LEAVE THE DESK - Getting away from the desk at lunchtime (or anytime) could help you to refocu and get reenergized. Whether it's a quick walk or a long lunch, take some time to wake up away from the glowing screen. Those emails can wait a few minutes. Really.
9) TURN UP THE HEAT - Being too cold may cause the body's temperature to drop, which tells it "time to sleep!" Throw on a sweater or turn up the heat to fight off that drowsy feeling.
10) CHUG CHUG CHUG - Whether at the gym or just dealing with the daily grind, it can be hard to remember to drink enough water. But even the most mild dehydration can cause groginess, so try chugging a glass or two when fatigue strikes. Or, better yet, stay hydrated all day long! Carry a big tumbler cup or water bottle with you to make it easier to keep up on your water intake.
