Everyday health

Why do I wake up tired even after 8 hours of sleep?

Because sleep duration and sleep quality are different things. Eight broken hours restore less than six unbroken ones. The usual culprits are an irregular sleep time, alcohol, late heavy meals, a warm room, and untreated snoring. If you snore loudly with pauses in breathing, that needs a sleep study rather than better habits.

People count hours because hours are easy to count. What actually determines how you feel is whether you cycled properly through deep and REM sleep, and how many times you surfaced without remembering it.

The things that most often break sleep quality

  • A sleep time that moves by more than an hour between weekdays and weekends — the body treats it as jet lag
  • Alcohol, which shortens the time to fall asleep and then fragments the second half of the night
  • A heavy meal within three hours of bed, which is common when dinner is at 10pm
  • A bedroom above roughly 26°C — core temperature has to drop for deep sleep to happen
  • Caffeine after about 2pm, which has a half-life of five to six hours in most adults

When it is not a habits problem

Loud snoring with pauses in breathing and daytime sleepiness may indicate sleep apnoea, which no amount of sleep hygiene will fix and which needs a sleep study.

Persistent fatigue with weight loss, fever, breathlessness or swollen glands needs medical investigation before it is treated as a lifestyle problem. Fatigue has causes that must be ruled out, not managed.
