Sleeping in a hot bedroom, increased pressure for the elderly's heart
A recent study found that bedroom temperatures above 24 degrees can significantly increase cardiac stress in the elderly.
TL;DR
- Bedroom temperatures above 24 degrees Celsius can significantly increase cardiac stress in older adults.
- A study monitored heart rate variability in 47 adults over 65.
- Higher bedroom temperatures were linked to increased cardiovascular stress and reduced heart recovery during sleep.
- Temperatures between 24-26 degrees Celsius increased cardiac stress by approximately 40%, 26-28 degrees by 100%, and above 28 degrees by 300%.
- The body works harder to cool down in warmer temperatures, expanding blood vessels near the skin and increasing blood pumping, which strains the cardiovascular system.
