8. Nobody sleeps through the night
We all wake up several times throughout the night, mostly without even realising, whether that’s due to being too hot or cold, partner movement, kids or noise. Waking through the night isn’t anything to worry about, according to The Sleep Council; we go through different stages as we sleep and these are peppered with brief awakenings.
9. Altitude affects sleep
When you're at altitude (approx. 13,200 ft plus), there is less oxygen which makes it much harder to go to sleep.
10. Our sense of smell decreases when we’re asleep
Studies have shown that noise can wake us up as we slumber, but smells won’t, which is one of the reasons fire alarms were invented.
