Zi and Chou Hours: Why TCM Wants You Asleep Before 11 p.m.

Grove Flow

From 11 p.m. to 3 a.m., the Gallbladder and Liver meridians take their turn at peak time. Miss that window, and no amount of catch-up sleep the next day feels quite the same.

CDC data shows that about 30% of American adults get less than 7 hours of sleep a night. For many, it isn’t that they don’t want to sleep. They just can’t fall asleep, or they wake up in the small hours.

The Zi and Chou Hours

Zi hour (11 p.m.–1 a.m.) is Gallbladder meridian time, and Chou hour (1–3 a.m.) is Liver meridian time. In TCM, these four hours are when qi and blood return to the Liver and Gallbladder to restore and replenish.

Moving Your Bedtime Earlier

1. Go to bed 15 minutes earlier each night, shifting a little at a time over a week. It’s far easier to stick with than jumping two hours at once.

2. An hour before bed, dim the lights, put your phone away and soak your feet for 15 minutes.

3. Once you’re lying down, press Shen Men on the ear (auricular Shenmen) and take 10 slow breaths, making each exhale longer than the inhale.

If your insomnia lasts more than three weeks, or it seriously affects your work or mood during the day, please consult a doctor.
