New study has found that the optimal temperature for sleep in older adults is between 15 and 25 degrees Celsius.
Moving above this temperature range can lead to a 5-10% drop in sleep efficiency.
The study was conducted on 50 older adults who wore sleep monitors and environmental sensors for 18 months.
There was a great deal of variation in the optimal sleep temperature between individuals.
Climate change could make it harder for older adults to get enough sleep as nights get hotter.
Various adaptive strategies can help older adults get better sleep in warm temperatures, such as drinking plenty of water, wearing breathable sleepwear, and avoiding screens before bed.
