TCM perspective on sleep duration
Is it necessary for optimal health that everyone gets 7–9 hours of sleep each night?
I know many people seem to function well on less than that while still waking up at a consistent time every day.
For example, my father wakes up around 5–6am daily and usually gets less than 6 hours of sleep.
Some of my friends who wake up early to train at the gym also regularly sleep only 5–6 hours and say that’s all they need.
I’m just wondering whether TCM views shorter sleep duration as a concern in the same way Western medicine generally does.
