Just 16 percent say they don’t feel sleepy at all in a typical week (this excludes sleepiness at bedtime and when waking up). About half, by contrast, feel sleepy anywhere from three to seven days a week. That includes a big gender gap: Women report feeling sleepy 3.4 days a week, on average; men, 2.7 days.

Among the approximately three in 10 Americans who have feelings of sleepiness on five to seven days a week, 52 percent report often or sometimes experiencing irritability when sleepy; 40 percent, headaches; and 34 percent, feeling unwell apart from headaches.
