The Best Time Of Day To Drink Coffee

Steven Miller:

Although your cortisol levels peak between 8 a.m. and 9 a.m., there are a few other times where–on average–blood levels peak again, like between noon and 1 p.m., and between 5:30 p.m. and 6:30 p.m. In the morning then, your coffee will probably be the most effective if you enjoy it between 9:30 a.m. and 11:30 a.m., when your cortisol levels are dropping before the next spike.

Right about when I need a cup of joe.
