Scientists Determine Optimal Sleep Temperature for Elderly Individuals

Researchers conducted a study that identifies the optimal range of room temperatures for achieving quality sleep among older individuals. As reported by Healthline, this range spans from 20°C to 25°C.

Scientists gathered and analyzed data from 50 elderly participants. The study encompassed 11,000 nights of sleep and collected information about the surrounding environment. Participants utilized specialized sleep monitors and environmental sensors that tracked various aspects of sleep, such as duration, quality, and restfulness.

"Dimmed ambient lighting and appropriate temperature before sleep send signals to the body to release neurotransmitters that facilitate sleep," notes Dr. Sudha Tallavajhula, a sleep neurologist at UTHealth Houston and TIRR Memorial Hermann.

It was found that temperature fluctuations within the range of 25°C to 30°C adversely affect sleep quality, leading to a decrease in its effectiveness. According to Tallavajhula, high room temperatures during deep sleep hinder the body's ability to regulate temperature, potentially resulting in more frequent awakenings during the night.

Furthermore, this study highlights the potential negative impact of climate change on sleep quality among older individuals. Specifically, elderly individuals without adequate means to cool their living spaces may experience compromised sleep quality due to extreme temperatures.

"Both climate change and the warming effect caused by cities (urban heat island effect) can significantly elevate nocturnal temperatures. Thus, we anticipate worsened sleep quality among individuals, as urban temperatures rise," stated lead researcher Amir Baniassadi.

Additionally, researchers emphasize that individuals with lower socio-economic status are at a higher risk of poor sleep. This demographic often resides in housing structures that are prone to overheating, particularly in densely populated urban areas with limited greenery, where the intensity of the "urban heat island" effect is more pronounced. Moreover, access to proper medical assistance to address the potential health consequences of inadequate sleep is limited within this population group.
