You're Tired...But Only Just Before (and the First Day Or Two of) Your Period
That pre-flow dragginess is due to a hormone-induced dip in levels of the brain chemical serotonin, leaving you feeling sluggish. It might also be the result of cramps interrupting your sleep. Keep the cramps under control with pain relievers, and make sure you don’t skip the gym as working out will pump your energy.
You're Tired...But the Exhaustion Only Strikes Within an Hour After You Eat Lunch
You’re in a carb coma. White-flour breads and other starchy lunch staples get turned into sugar by your digestive system quickly, which causes your bloodsugar levels to spike.

Stay alert by aiming for seven to eight hours of uninterrupted quality shut-eye a night. Avoid caffeine after 4pm, and turn off your gadgets before bed.

The human body normally hits a wall for about two hours in the late afternoon, and the sloth-y feeling gets even worse when you instinctively down a bag of greasy chips that leave you feeling full and lazy. Here’s the right way to fight the fatigue: get up from your chair and start stretching, take a relaxing 10-minute walk outside for a fresh-air fix, and/or have a glass of cold water or a highprotein snack, like a handful of nuts, which will revive you.
