Why do they start so insanely early though every teacher knows that first period is a waste of time
Because if they didn’t the students’ sleep cycles would shift further and people like you would be complaining that the new first period (former second period) is a waste of time.
every parent knows what happens to teenagers’ circadian rhythms?
So what happens to them. I believe they tend to stay up late and be extremely night shifted. Wouldn’t starting school late only make the problem worse?
The phase-response curve of the circadian rhythm to light shifts with age, with the equilibrium position of the wake point latest in the late teens and earliest in early childhood and old age.
