Along with diet, exercise and a healthy lifestyle, getting enough sleep is one of the foundations for good health.
According to new research in the journal Science of the Total Environment , temperature affects the quality of your sleep. Adjusting the temperature to the right level can help you sleep better and be healthier.
The optimal sleeping temperature in the bedroom of the elderly is between 20 and 25 degrees Celsius.
Temperature and sleep quality
Ambient temperature is an important factor in helping you fall asleep and stay asleep.
"At the onset of sleep, ambient light and temperature send signals to the body to release neurotransmitters that influence the process of falling asleep," says sleep neurologist Dr. Sudha Tallavajhula. "During sleep, our body temperature fluctuates at different levels."
What does the new research find?
In a study published in the journal Science of the Total Environment , participants wore sleep trackers and environmental sensors that tracked sleep duration, efficiency, and sleepiness. Researchers collected data from 50 older adults and information about their sleep environments.
Findings showed that sleep efficiency decreased by 5 to 10 percent when the temperature increased from 25 degrees Celsius to 30 degrees Celsius.
Research highlights the impact of climate change on sleep quality in older adults.
"Both climate change and global warming can significantly increase night-time temperatures. Meanwhile, our study found that sleep quality declines rapidly as night-time temperatures rise above 25 degrees Celsius. Therefore, we predict that sleep quality will decline as cities get warmer," the researchers point out.
Based on research results, scientists believe that the optimal sleeping temperature in the bedroom of the elderly is from 20 to 25 degrees Celsius.
Habits to improve sleep
Practicing good habits regularly can improve the quality of sleep. These habits include: sleeping and waking up at fixed times during the day, maintaining low light, low temperature, keeping the body relaxed before sleeping...
