Feeling sleepy after that lunch out with your officemates? According to Business Insider, that's perfectly normal. It's a sign that your internal clock is working and that your blood sugar levels are responding well to the food that you ate.
But even if you didn't come from lunch, an afternoon slump is still natural. The New York Times reports that it's normal to want to fall asleep seven hours after waking up.
"First, the 24-hour cycle of the body, or its circadian rhythm, is naturally in a resting phase at this time. In the afternoon, it happens to converge with another physiological cycle—known as homeostatic—that measures the amount of time spent awake and that is also pushing for a rest."
Can't afford to take a nap? Here's what you can do to wake yourself up:
Eat at regular times.
Having late lunches may be par for the course at the office, but try to avoid eating at unhealthy times. According to WebMD, this "prevents energy deficits during the day that will aggravate your sleepiness."
If your office has a gym, try light aerobic exercises to ward off sleepiness and boost productivity, reports Greatist. Don't have time to hit the walker? Do desk exercises instead!
Sugar can give you a temporary high, but binge on sweets and you'll definitely find yourself crashing sooner or later. Stick to whole grains and protein, suggests New York Magazine.
Time your coffee break right.
Your body produces cortisol to keep you alert and awake at specific times. Avoid drinking coffee around the same period and stick to these time slots: 9:30 a.m. to 11:30 a.m and 1:30 p.m. to 5:00 p.m.
