Cardiologist Explains: How to Sleep Without Air Conditioning During a Heatwave?

Spanish cardiologist José Abellán has shared important advice on how to get healthy and quality sleep during these days when high temperatures persist. He emphasized that it is possible to lower body temperature naturally, especially in situations where cooling devices like air conditioners or fans cannot be used. He noted that heatwaves severely disrupt sleep patterns, which can have negative effects on heart health. The expert had previously warned the public about the health risks of certain daily consumed foods. This time, he focused on the key tips for resting during hot summer nights.

According to Abellán, sleeping in a hot room can cause stress hormones to increase and the heart to beat faster. This situation leads to frequent awakenings during the night and starting the day without feeling refreshed. He stated that for those who do not have access to air conditioning or prefer not to use it, the most basic rule is to keep the bedroom cool during the day. Keeping curtains and windows tightly closed when the sun is at its peak angle largely prevents the room from heating up. This simple method helps maintain a cooler environment in the room during the evening hours.

The cardiologist noted that pre-bedtime preparations directly affect sleep quality, recommending taking a warm shower before going to bed. Although a warm shower initially raises body temperature, the subsequent sweating process triggers a mechanism that rapidly cools the body down. This allows the person to feel much more comfortable and cool when getting into bed. Additionally, he emphasized that bed sheets and pajamas should be chosen from breathable natural fabrics like cotton or linen. Synthetic fabrics can trap body heat and increase sweating, making sleep impossible.

Another important point highlighted by the expert is the food and beverages consumed during the day and right before bed. It is vital to keep the body hydrated during heatwaves, but consuming large amounts of fluids close to bedtime can lead to frequent trips to the bathroom at night. Therefore, it is recommended to spread water consumption throughout the day. Similarly, consuming heavy and fatty meals late at night strains the digestive system, increasing body temperature and interrupting sleep. Abellán also added that stimulants like caffeine and alcohol should be further avoided during hot periods.

In conclusion, Abellán emphasized that sleep problems caused by heatwaves are not unsolvable, noting that small lifestyle changes can make a big difference. Properly ventilating the bedroom, keeping curtains closed during the day, and establishing the right nighttime routine are the keys to sleeping comfortably without air conditioning. Healthy sleep is an indispensable necessity for both heart health and overall body functions. It is noted that starting to try these methods tonight can provide significant relief during hot summer nights. The doctor's recommendations serve as a highly practical guide, especially for those who do not have cooling devices or wish to save energy.
