How to get your energy back

Got a bad case of the Mondays? If you struggled to get out of bed this morning, or are struggling not to do a face-plant at your keyboard right now, Dr. Roshini Raj has some advice. A TODAY contributor and contributing medical editor at Health magazine, Dr. Raj offers these tips (and more in the video) for finding more energy:

Turn off the light: Avoid "blue light" from your tech devices after dinner; blue light has the biggest impact on circadian rhythm, slowing production of melatonin, a hormone that helps us sleep.

Power snack: Don't skip meals, and eat every four hours; the perfect snacks are fewer than 200 calories and include a mix of carbs, protein and fiber. Examples: One hardboiled egg and one banana; a cup of Greek yogurt with fresh or frozen blueberries; one pear and three slices of turkey breast.

Get out: It's not your imagination, going outside does energize you. Music has a similar effect, especially if you move to the beat -- even if it's just tapping your feet.

B12 shots? Probably not: Though they've become something of a fad recently, Dr. Raj says that unless you are actually deficient in vitamin B12, a shot of it won't affect your energy level.

Finally, if you're deeply fatigued all of the time and the normal advice for restoring energy seems to work, see a doctor. There could be an underlying medical problem at the root.
