The Effects of High-Temperature Weather on Human sleep Quality and Appetite

This study evaluated how high temperatures (28°C, 32°C, 36°C, and 38°C) influence sleep quality and appetite. sleep at 32°C resulted in the best quality, with the longest total sleep duration and minimal disturbances, while 36°C and 38°C led to significant declines in sleep quality, including reduced total sleep time and increased shallow sleep. High temperatures also suppressed appetite, particularly at lunch, with lower food intake and shorter meal durations. These findings highlight the impact of thermal environments on rest and nutritional behavior, vital for maintaining cognitive and physical health.

To improve sleep and appetite in hot weather, maintain room temperatures close to 32°C with ventilation or air conditioning. Adjust mealtimes and stay hydrated to mitigate heat effects on appetite. Tailor strategies based on local climate and individual comfort.
