Summer brings longer days, warmer evenings, and plenty of reasons to celebrate — but for many, it also means restless nights. When the sun stays out late and temperatures stay high, getting a good night’s sleep can feel like an impossible challenge.
“Heat and light are two of the biggest disruptors to our natural sleep cycle,” explains Dr. Sarah Mitchell, a sleep specialist based in London. “Our bodies rely on a drop in temperature and darkness to signal that it’s time to wind down. When those cues are missing, falling asleep and staying asleep becomes harder.”
One simple but effective strategy is to keep your bedroom as cool as possible. “Using fans or air conditioning can help regulate the temperature,” says Dr. Mitchell. “If you don’t have air conditioning, try keeping windows open at night to create a cross breeze, and close curtains during the day to block out heat.”
Light pollution is another culprit. The longer daylight hours can confuse your body’s internal clock. Sleep expert Tom Reynolds recommends blackout curtains or even a sleep mask to create darkness inside your room. “Melatonin, the hormone that controls sleep, is released in response to darkness. Without it, your body struggles to feel sleepy.”
Other tips include sticking to a consistent bedtime routine, avoiding caffeine and heavy meals late in the day, and limiting screen time before bed, as blue light from devices can interfere with melatonin production.
“Summer is a great time to enjoy outdoor activities, but try to avoid vigorous exercise close to bedtime,” adds Reynolds. “Your body temperature rises during physical activity, making it harder to cool down for sleep.”
While the summer months may present challenges, small changes can make a big difference in helping you get the rest you need, so you can wake up refreshed and ready to enjoy the season.
