Most healthcare professionals recommend moderate your caffeine in coffee, tea or caffeine consumption to limit the risks of chronic health problems. If you can’t get by without your morning cup of joe to keep you awake, don’t worry - you don’t need to ditch it. As long as you stick to no more than five 8-ounce cups of coffee per day, you shouldn't have to worry about too many adverse effects. That being said, if you don’t drink coffee yet, there’s really no reason to start. If you are having difficulty sleeping because of your afternoon coffee, it may be time to rethink your caffeine consumption habits to help you develop a more natural sleep routine.
