The intense heat and humidity of May-June are affecting the sleep of many people at night, a condition medically known as summer insomnia. This problem is not solely dependent on the weather but is also linked to physiology. For good and deep sleep, it is necessary for the body's internal temperature to decrease, but high room temperatures and humidity during summer disrupt the body's thermal regulation system. Additionally, the longer days and late sunsets confuse the brain's natural clock, causing the sleep hormone melatonin to be released late. Dehydration due to sweating at night also increases restlessness, leading to interrupted sleep. To combat this issue, bathing with lukewarm water before sleeping helps immediately lower body temperature. Furthermore, it is important to avoid caffeinated beverages after 6 PM and have a light, non-spicy dinner.
