Always wake up early at 5AM, Why? Due to TSH or not?

[Guest guest]

Hi, folks.

Recently I have the same " symptom " every day. I always wake up at around

5AM early in the morning, and after a while, I either get up to do

things, or go for sleep again. I am confused about the reasons for it.

I read an article about TSH secretion, it said that " a nocturnal surge

beginning after 1900h, and higher concentrations between 2200 and

0400h. Peak TSH levels between 2200 and 0400 h are followed by a

gradual decline between 0400 and 1000 h to nadir TSH levels. Small

frequent pulses occur as an overlay on this overall sin wave-shape

circadian pattern. Thus, at least one-third of trophic influence of TSH

on the thyroid gland occurs during the hours of sleep. "

Would it be caused by TSH levels?
