If you're the type of girl who can't function without a cup of joe every day, you may have already developed a high tolerance for the morning brew. This makes it less effective, causing yourself to chug down more cups. Now, according to a video by AsapScience, you've been drinking coffee wrong, and body clock is a factor with its efficiency.

Experts say that you shouldn't drink coffee from between eight and nine o'clock in the morning—the most common time everyone does a coffee run! This is because our bodies release the hormone cortisol, more commonly known as the stress hormone that keeps us up and alert all day, during this time.

So if you're aiming to get a jolt from coffee during this time, you're actually counteracting your body's natural energy boost. Other times of cortisol production are between noon and 1:00 p.m. and 5:30 p.m. to 6:00 p.m, so avoid taking in caffeine at these hours. The best times to have a coffee break? Plot these hours in your planner: 9:30 a.m. to 11:30 a.m and 1:30 p.m. to 5:00 p.m.
