How people woke up before alarm clocks

> "In many pre-industrial societies, daily life followed the rhythm of sunrise and sunset, which naturally shaped circadian rhythms."

Having an office job that allows for flexible hours, I start my working day at different times during the year. Setting the alarm to the latest hour that I can start to work it never wakes me up, but it is there just in case.

Overall, I feel that I am less stressed, sleep better and have more energy that if I force myself a schedule to wake up. What I have is a schedule to go to sleep, the rest I leave to nature.
