If you’re reading this in the morning, it’s likely you’re cradling a steaming cup of coffee in your hands.
While putting in long hours at work causes many entrepreneurs to nurse the coffee pot, studies show caffeine has some serious side effects that can hinder your performance at work.
Push the cup of joe aside and decide whether you still want it when you finish reading this.
Caffeine can take a while to leave your system. If your first cup is at 8 a.m., 25 percent of caffeine will still be in your body at 8 pm. Any amount of caffeine left in your body will result in reduced REM sleep – the deep sleep your body needs to recharge. Research by Wayne State University published in the Journal of Clinical Sleep Medicine showed drinking coffee on the way home from work can impair sleep quality. Caffeine consumed six hours before bed reduced sleep by at least one hour.
