Did some research on whether it's normal to wake up once at night. So it's actually common! - continuous sleep experienced in childhood/teens is not typical for adults - most people wake 2-3x during the night - historically, humans don't sleep 8h. The terms "first sleep" and "second sleep" is hundreds of years old. - industrialisation / electric light made waking activity encroach further into the night - we wake in night due to sleep cycles, a normal sign of body's internal clock and sleep mechanisms working well https://sleephub.com.au/wake-up-at-night/
