All hail the 10-15 min toilet nap and locks on bathroom doors. Yes our country as a whole underestimates and stigmatizes healthy sleep patterns. People and companies which recognize the great benefits of short mid-day brain resets/toxin flushes (naps) are excellent but uncommon. Two cups of coffee won't accomplish what one 10-15 min afternoon nap achieves. It also matters what and how much you eat for lunch because the wrong foods or amounts can cause drowsiness even in well-rested people. I find that vegetarian meals make me less sleepy than meat-heavy meals.
