Being a night owl, I was joking around with a friend of mine that dentists like to schedule morning sessions to kick up a notch on the torture factor.
However, someone mentioned that pain tolerances are actually lower in the morning.
Is there any evidence for this?
Why would pain tolerance be lower in the morning than in the afternoon? Shouldn't it be the opposite, since your nerves are all rested, and more ready to take the beating of the day to come?
