Reduced sleep quality during heat waves
According to sleep experts, "tropical nights" are harmful. Deep sleep is a pipe dream if the temperature does not drop below 20 degrees at night. Studies have shown that it is often more difficult for people to fall asleep. Also, the waking phases are longer at night. The so-called "REM sleep" is somewhat reduced. People often dream more intensively, and their eye movements are faster. In addition, the heart beats faster.
