Bedroom Heat Boosts Heart Stress
19 Feb
Summary
- Temperatures over 24°C increase heart stress in seniors.
- Elderly hearts work harder to cool down in warm rooms.
- Higher bedroom temps significantly raise cardiovascular risks.
New research indicates that elevated nighttime bedroom temperatures pose a significant risk to cardiovascular health, particularly for the elderly. A study involving 47 adults aged 65 and above revealed that sleeping in rooms exceeding 24 degrees C (75.2 degrees F) leads to increased heart stress and hinders recovery.
During warmer nights, the heart expends more energy circulating blood to the skin for cooling. This extra exertion places a considerable burden on the cardiovascular system, with risks escalating significantly as temperatures climb. For instance, temperatures between 26-28 degrees C nearly double the risk of heart stress.
The findings are particularly relevant given the increasing frequency of hot nights attributed to climate change. Maintaining a cooler bedroom environment, around 24 degrees C, is advised to mitigate these heightened physiological stress responses during sleep and support overall cardiovascular well-being.
