The UK is getting its first burst of summer over the Bank Holiday, with temperatures expected to skyrocket. That's great news for our plans (and serotonin levels), but come nighttime, the heat may make it difficult to fall asleep.
Sleeping better in the heat is about keeping body temperature regulated. It plays an essential role in the sleep cycle. "Many people underestimate just how sensitive sleep is to temperature," says Omar El-Gohary, the superintendent pharmacist at IQ Doctor. "The body follows a natural circadian rhythm, and part of this process involves a drop in core body temperature of around one degree Celsius before sleep. This cooling process triggers the brain to recognise that it is time to reset."
