Take a Cold Shower
Katharine Hepburn swore by cold showers, and she had an epic energy level. If you can't commit to an all-together cold one, take your usual shower but turn off the hot water completely for the last two minutes to invigorate you. If you still can't handle it (come on, try it!), or if you want a mid-day alternative, splash some ultra-cold water on your face. We recommend keeping a spritz bottle in the fridge for moments such as these.
