The temperature of the bedroom at night could affect heart health<\/a> \u2014 particularly in older adults.<\/p>\n

Heat places extra demands on the cardiovascular system, according to lead study author Dr. Fergus O’Connor from Griffith University in Queensland, Australia.<\/p>\n

When the human body is exposed to heat, its reaction is to work harder to try and circulate blood to the skin surface for cooling, he noted.<\/p>\n

“However, when the heart works harder and for longer, it creates stress and limits our capacity to recover from the previous day’s heat exposure,” O’Connor stated in a press release.<\/p>\n

Researchers aimed to understand how real-world bedroom temperatures affected older adults<\/a>.<\/p>\n

When the heart works harder and for longer, it creates stress and limits its capacity to recover from the previous day’s heat exposure.<\/p>\n

The team followed 47 adults living in southeast Queensland averaging 72 years of age.<\/p>\n

While many sleep observations are conducted in special clinics, this was a “free-living” study, meaning the participants carried on with their normal activities and sleep schedules.<\/p>\n

Scientists monitored the participants throughout an entire Australian summer, from December to March. Each person wore a high-tech fitness tracker<\/a> to monitor their heart rate from 9 p.m. to 7 a.m., according to the release.<\/p>\n

While many sleep observations are conducted in special sleep clinics, this was a “free-living” study, meaning the group carried on with their normal activities and sleep schedules.<\/p>\n

Sensors were then placed directly in participants\u2019 bedrooms to record the temperatures, monitoring over 14,000 nighttime hours of sleep in total.<\/p>\n

Sleep Timing Could Directly Impact Chances Of Heart Attack Or Stroke, Study Suggests<\/a><\/p>\n

The temperature at which the heart began to show signs of disruption was a little more than 75 degrees Fahrenheit.<\/p>\n

Between 75 and 79 degrees Fahrenheit, the odds of a “clinically relevant” drop in heart recovery<\/a> rose by 40%, the researchers found.<\/p>\n

Between 79 and 82 degrees Fahrenheit, the odds doubled. Above 82, the risk was nearly triple compared to cooler rooms.<\/p>\n

Between 75 and 79 degrees Fahrenheit, the odds of a “clinically relevant” drop in heart recovery rose by 40%.<\/p>\n

“For individuals aged 65 years and over, maintaining overnight bedroom temperatures at 24 C (75.2 F) reduced the likelihood of experiencing heightened stress responses during sleep,” O’Connor said.<\/p>\n

While the study shows a strong link between heat and heart stress, its observational design means that it doesn’t definitively prove heat is the only cause, the researchers acknowledged.<\/p>\n

As the study only focused on older adults in Australia, it may not apply to other populations.<\/p>\n

Also, while the wearable devices are advanced, they are not as precise as the medical-grade ECGs<\/a> used in clinical settings.<\/p>\n

O\u2019Connor emphasized a gap in temperature guidance \u2014 while there are guidelines for maximum daytime indoor temperature, there are no equivalent recommendations for nighttime conditions.<\/p>\n
