A new study has found that the optimal bedroom temperature for a restful night's sleep is between 68 and 77 degrees Fahrenheit. Researchers monitored the sleep patterns of participants aged 65 and over and discovered that temperatures above 86 degrees Fahrenheit led to the most restless sleep. The study suggests that creating a comfortable home environment with the right temperature range could improve sleep quality, especially for older adults. Another study highlighted the importance of getting seven hours of sleep for optimal cognitive function and mental health, emphasizing the significance of quality sleep at all stages of life.
