How to Get a Good Night’s Sleep During Hot Weather

How to get a good night – As the UK experiences a prolonged heatwave this week, temperatures are expected to surpass historical records for both daytime and nighttime warmth in June. While the sweltering conditions can disrupt sleep, practical adjustments can help restore restful nights. Experts emphasize that heat affects the body’s ability to regulate temperature, leading to fatigue and reduced alertness during the day. However, nighttime rest can still be salvaged with intentional strategies.

Adjusting Daytime Habits for Better Sleep

When the weather is stifling, the body expends extra energy to maintain its internal balance, which can leave you feeling sluggish. This phenomenon is often overlooked, but it’s crucial to avoid daytime naps if nighttime sleep is compromised. “Sleepiness during the day is a precious resource,” says Lisa Artis of the Sleep Council. “It should be reserved for bedtime to ensure you’re fully rested.”

Keeping the Bedroom Cool

One of the most effective ways to combat heat-related sleep issues is to create a cooler bedroom environment. Closing curtains or blinds during the day can block sunlight, reducing indoor temperatures. On the sunny side of the home, ensure windows are tightly shut to prevent hot air from entering. As night falls, open all windows to allow a steady breeze. For added comfort, consider replacing heavy bedding with lighter layers, while keeping covers within reach for quick adjustments.

Cotton sheets are recommended for their ability to wick away moisture, but loose-fitting clothing made from natural fibers like linen or silk can also contribute to a cooler sleep. “Even in a sweltering room, the body naturally cools during the night,” explains Prof Kevin Morgan, former director of the Clinical Sleep Research Unit at Loughborough University. “Wearing breathable fabrics helps facilitate this process.”

Managing Hydration and Fluid Intake

Staying hydrated is essential, but timing matters. Drinking adequate water throughout the day helps counteract the effects of heat, yet consuming large amounts close to bedtime can lead to frequent trips to the bathroom. “Striking the right balance is key,” notes Artis. “You don’t want to wake up parched, but you also need to avoid disrupting your sleep cycle.”

Soft drinks and alcohol should be limited, especially in the evening. While these can initially induce drowsiness, they often result in early awakenings and poorer sleep quality. “Alcohol may help you fall asleep faster, but it interferes with the deep, restorative stages of sleep,” Morgan adds. “This can leave you feeling unrested, even after a full night.”

Calming Activities for Restless Nights

If sleep proves elusive, engaging in soothing activities can help. Reading, journaling, or folding laundry are gentle options that distract the mind without overstimulating it. However, the glow of electronic screens should be avoided. “The blue light emitted by phones can trick the brain into thinking it’s still daytime,” warns Artis. “This may delay the onset of sleep and reduce its quality.”

Children and babies, though typically resilient, are especially vulnerable to environmental changes. Maintaining their usual bedtime routines is vital, even during warm spells. The NHS UK website advises lukewarm baths as part of the evening ritual, but warns against excessively cold water, which could raise their body temperature instead of lowering it.

Monitoring Temperatures for Babies

For infants, whose ability to regulate body heat is limited, room temperature is critical. “A baby’s optimal sleep environment lies between 16°C and 20°C,” says Morgan. “Use a thermometer to track conditions and adjust accordingly.” Parents should remain vigilant, as babies cannot communicate if they’re too hot or too cold. This vigilance is even more important during heatwaves, when temperatures can easily exceed comfortable ranges.

The Science of Sleep During Heat

Despite the challenges, the human body has mechanisms to adapt. During the night, core body temperature naturally drops, which is why some people wake up feeling chilly even in a warm room. This physiological shift is key to initiating and maintaining sleep. To enhance this process, using a small fan or placing a cold water bottle near the bed can promote airflow and aid in temperature regulation. “A fan’s gentle breeze can accelerate sweat evaporation, making it easier for the body to cool down,” Artis explains.

Expert Insights and Practical Advice

The advice offered here is rooted in scientific research and expert recommendations. Prof Kevin Morgan and Lisa Artis, both affiliated with the Sleep Council and Clinical Sleep Research Unit, stress that consistent habits are more effective than quick fixes. “While hot weather may tempt you to deviate from your routine, small changes in sleep practices can yield significant results,” Morgan says.

Though most adults can function after a couple of sleepless nights, the cumulative effects of heat on sleep should not be ignored. Prioritizing rest during hot periods ensures better daytime performance and long-term health. As the article was first published in July 2019, it continues to offer relevant guidance for navigating summer heatwaves.

“Sleep is a vital component of health, and maintaining it during extreme weather requires adaptability and attention to detail,” says Lisa Artis.

Conclusion: Adapting Without Compromising

While the heat may challenge traditional sleep patterns, proactive measures can help. By focusing on environmental adjustments, mindful hydration, and preserving bedtime rituals, individuals can mitigate the impact of rising temperatures. Children and babies, in particular, benefit from structured routines that provide stability in uncertain conditions. As Morgan highlights, even minor changes—like using a fan or switching to breathable fabrics—can make a meaningful difference.

Remember, the goal is to maintain a balance between comfort and rest. With patience and small adjustments, a good night’s sleep is still achievable, even in the heart of summer.
