The first heatwave of the summer has arrived and tado\u00b0<\/strong><\/a> reveals in a study that Spaniards were the worst sleepers in Europe last summer due to high temperatures. In addition, it has been shown that it is not necessary for the average outside temperature during the day to be very high to spend sweltering nights and that high temperatures during the night alter the body’s schedule, causing restlessness, reduction of deep waves and the REM phase.<\/p>\n\n\n\n

Last summer, Spaniards suffered the worst sleep difficulties in Europe, with indoor temperatures in homes exceeding 27\u00b0C for 18 consecutive nights. Sleep Charity experts say that a large proportion of the population suffers from night-time insomnia when bedroom temperatures are at or above 24\u00b0C(1); in the case of Spaniards, this temperature was maintained on all but four nights in the summer of 2023(2).<\/p>\n\n\n\n

Moreover, while the country is in the midst of its first heatwave, tado\u00b0 reveals that the average daytime outside temperature does not need to be very high to make for a sweltering night. In fact, according to a study of temperatures in more than 35,000 Spanish homes, it shows that the average outdoor temperature during the day can drop to as low as 19\u00b0C, while the indoor temperature at night can reach 24\u00b0C.<\/p>\n\n\n\n

Temperature significantly influences sleep quality<\/h1>\n\n\n\n

According to Sleep Charity, a bedroom temperature of 16\u00b0C to 18\u00b0C is ideal. In fact, the human body is thought to cool down at night, a sign that it is preparing for sleep, which is why it is difficult to fall asleep when it is too hot. Studies show that high night-time temperatures alter the body’s schedule, leading to increased restlessness, reduced deep-wave sleep and REM (rapid eye movement).<\/p>\n\n\n\n

In Spain, during 91 of the 95 summer nights in 2023, the average night-time indoor temperature exceeded 24\u00b0C. The highest recorded peak was in August, with 18 consecutive nights with temperatures above 27\u00b0C on average, the longest period in Europe, and two nights when the thermometer exceeded 29\u00b0C(3).<\/p>\n\n\n\n
