睡眠专家建议:早点起床,而不是早点睡觉。每天,包括周末,定时睡觉和起床。
I'm a sleep researcher. It does not have to be early, but one of the best ways to fix a sleep problem is to wake up consistently at the same time (even weekends or when you don't get enough sleep).
Add good sleep hygiene (good sleep environment and routines), healthy life style including exercise, and morning sunlight (drink your morning coffee outside), and you can go a long way to fixing many sleep problems.
