You land in your body with a start, or else it slowly comes into groggy focus: either way it’s night-time, but you are now awake. Why? Alice Gregory, a psychology professor at Goldsmiths, the University of London and the author of Nodding Off, says it’s quite normal to wake up during the night.
After dropping off, we move through different stages of sleep, a cycle that takes the average adult about 90 minutes to complete and speeds up towards morning.
“The night is also punctuated by brief awakenings,” says Gregory. “Typically, people return to sleep without realizing that they had ever been awake.” But sometimes we might at least be more aware of it, or pulled entirely awake. Reasons range from the fairly obvious (being too hot or cold, needing the loo, having a nightmare, a crying baby) to the medical (disordered breathing such as sleep apnea, or nocturia: excessive night-time urination).
