Hot Weather and Sleep: How High Temperatures Impact Your Rest

High temperatures can disrupt the body’s sleep cycles, leading to health problems. Can knowing strategies and remedies help manage sleep quality?

Hot Weather Sleep

Sleep is important for refreshing the mind and body and being productive in school, work, relationships, and overall health. With record-breaking temperatures becoming the norm, consistently sleeping healthy is becoming difficult as forecasters predict another scorching summer with above-average temperatures. 2023 was the hottest year ever recorded. (National Oceanic and Atmospheric Administration. 2024) Studies show that high temperatures make it hard to fall asleep and stay asleep, which can negatively affect the immune system, cardiovascular system, cognitive performance, and mood. (Zheng, G., Li, K., and Wang, Y. 2019) (Obradovich, N. et al., 2017) Throughout the night, the body cycles through different sleep stages. (National Heart, Lung, and Blood Institute, 2022)

Because the body’s temperature regulation is less effective during certain stages, a hot environment can cause waking so the body can thermoregulate. The right temperature is imperative for a healthy night’s sleep. For optimal sleep, it is recommended that the bedroom temperature be between 65 and 69 degrees Fahrenheit. However, this isn’t always possible without air conditioning, which increases electricity bills. Here are other strategies to help keep the body cool for better sleep in hot weather.

Cooler Sleeping Environment

Thinking creatively about sleeping arrangements can help. Try to find the place that is the coolest and has the most airflow. Shutters or curtains during the day can help keep the room dark and cooler, and opening the windows can increase airflow. (Fergus Nicol, 2019) Using a fan can help improve air circulation, and putting ice behind the fan can blow cooler air for improved sleep.

Cooling Pillows and Breathable Pajamas

Pajamas and bedding made from breathable fabrics can help keep the body cool, and cooling mattress toppers or pillows can also help. Cooling pillows have gel overlays that absorb body heat and cool the head and neck. Keep an ice pack on the bedside table and a towel and ice to keep the body cool.

Take a Slightly Warm Shower

Taking a cold shower can cool the body down quickly, but studies have shown that showering in warm water before bed can make it easier to fall asleep. (Tai, Y. et al., 2021) The warm shower signals the body into cooling mode, which can help promote sleep as the body temperature falls at night. However, the water shouldn’t be too warm, which could exacerbate sweating.

Sleep Hygiene

It can be difficult to create the perfect sleep environment in hot weather. A healthy going-to-bed routine is essential in the summer, as stress and anxiety can significantly affect sleep quality. Avoid eating close to bedtime, avoid alcohol, and add some time to relax and unwind before going to bed. Sleep experts suggest general sleep hygiene habits like keeping a consistent bedtime and turning off screens an hour before bed can help improve sleep, even in hot weather. (Baranwal, N., Yu, P. K., and Siegel, N. S. 2023)

Chiropractic Treatment

Chiropractic care, massage, and decompression therapy can help improve sleep. Treatment retrains the body to relax; stretching and pulling the muscles increases blood circulation and advanced and improved brain signals telling the body to relax. A chiropractor will evaluate the individual’s sleeping patterns and recommend various strategies. Benefits include:

• Muscle tension relief.
• Stimulates nerve and blood circulation.
• Relaxes the whole body.
• Enhances central nervous system function.
• Relieves pain and discomfort.
• A chiropractor will also provide:
• Sleeping position recommendations.
• Postural stretches and exercises.
• Recommendations on supportive mattresses.
• Ergonomics for work, home, and bed.
