How many cups of coffee can you drink in a day?

Well, there's good news for your daily coffee habit. According to a November 2017 review published in Food and Chemical Toxicology, you can safely consume up to 400 milligrams of caffeine in a day (that's about 4 8-oz. cups of coffee or 6 shots of espresso). After reviewing 15 years of conflicting data, the study confirmed that consuming four cups of coffee doesn't have a negative effect on bone health, calcium intake, heart health or behavioral health, nor does it have a negative effect on reproduction and development.

In fact, regularly drinking up may ease depression in some women while possibly protecting against type 2 diabetes. An October 2018 study in Frontiers in Neuroscience identified compounds in coffee that may help protect against Alzheimer's and Parkinson's diseases.

So if you feel like drinking another cup, go ahead and indulge. Just bear in mind the side effects may be different person to person depending on your tolerance, weight and height. For example, overdoing it may actually cause anxiety, irritability, insomnia and migraines, according to the Mayo Clinic. At the very least, too much coffee can cause the jitters, which are no bueno before an important work meeting.

Finally, we recommend you curb your intake as the day progresses. Caffeine can disrupt your sleep up to six hours after consuming it, leading to an hour or more lost in rest, one study found. So stick to decaf after 3 or 4 p.m.

We know you love coffee, but on some mornings, why not change it up and try Yogi's Coffee, an energizing wakeup by Tamal Dodge, on the Yoga Wake Up app. It may leave you feeling as refreshed as you would if you'd had that cup...without the jitters.
