We mapped CDC county estimates of adults sleeping under seven hours: from 25% in Boulder to 51% in rural Alabama, tracking inactivity closely.

The median American adult falls asleep at 11pm and wakes at 6:30am on weekdays. We pulled the CDC's survey data to see how that shifts by age and on weekends.

We ran the numbers on the CDC's national sleep survey. Adults sleep 41 minutes longer on weekends, and those who need the catch-up most get the least.

We analyzed the CDC's sleep survey for 9,693 adults. Reported trouble sleeping doubles from the twenties to the fifties, and sleepiness tracks hours slept.

We analyzed the CDC's sleep survey for 9,170 adults. 23.9% report gasping or breathing pauses at night, and they are twice as likely to be sleepy all day.

Bedtime drift is a wake-time problem. A two-week plan that uses one morning text a day to pull your schedule back, with Sleep Textapp keeping score.

Bad nights have causes, and most people guess the wrong one. A two-week morning log, done by text, finds the real culprit faster than any gadget.

We matched CDC estimates of short sleep and frequent mental distress for every US county. The link is strong, and useful to anyone tracking their mood.
