|Researchers find best temperature for sleeping well
The key for older people to sleep well at night could be how hot or cold their room is. Researchers say the best way to get a good night's sleep is to make sure the bedroom is between 20-25º Celsius. The researchers are from Harvard University and the Hinda and Arthur Marcus Institute for Aging Research in the USA. They asked 50 people aged 65 and older to wear a sleep monitor for a year and a half. The researchers found that the quality of sleep worsened when the room temperature was outside the 20-25-degree range. They also observed that 20ºC was the best temperature. The lead researcher said: "Sleep tends to come easier and is often deeper and more restful in a cooler environment."
