Takeaway
Coffee has endless benefits (preventing the development of type 2 diabetes, improving physical performance, or promoting heart health) when consumed in moderation. Try to stick with the recommended amounts (no more than four cups of coffee a day) to enjoy its benefits.
If you have bad coffee habits, try to change them gradually, as an abrupt change can have serious consequences on your overall health.
Also, if caffeine is not the culprit of the signs and symptoms we’ve listed, but you still experience one or two, talk to your doctor as soon as you can.
