Recent scientific research suggests that avoiding the consumption of coffee and alcohol before bedtime can help improve sleep quality during periods of hot weather. Both coffee, which contains caffeine, and alcohol can interfere with the body's natural sleep processes. Caffeine is a stimulant that can delay sleep onset and reduce sleep duration, while alcohol, although it may initially induce drowsiness, can disrupt sleep cycles later in the night. In addition to modifying beverage intake, scientists also recommend taking cool showers before bed as a way to lower body temperature and promote better sleep. Studies have shown that higher nighttime temperatures, which are becoming more common due to climate change, are associated with reduced sleep quality and duration. These findings highlight the importance of adapting sleep habits in response to rising global temperatures.
