Do you tumble out of bed, head to the kitchen and pour yourself a cup of coffee? Experts say you should wait an hour before drinking a cup of joe!
Why? Researchers say this is the time your body's production of cortisol is at one of its three daily peaks.
Researchers say you can think of cortisol as nature's built-in alarm system. It's your body's main stress hormone and works with certain parts of your brain to control your mood. Your body produces more cortisol when under stress to increase alertness.
Health officials say consuming caffeine while your body is already at peak cortisol-production teaches your body to produce less. So while undermining the effectiveness of the caffeine, it also works against cortisol's alertness effect.
Researchers also add that if you have more than a cup a day, try to have your other doses at other peak cortisol production times -- between noon and 1 p.m. and between 5 and 6:30 p.m.
