A new study shows that keeping your bedroom at 24°C can help older adults sleep better and reduce stress. The research was led by Dr. Fergus O'Connor from Griffith University.

This study found that maintaining a bedroom temperature of 24°C overnight can lower stress responses during sleep in older adults. This is important because heat can increase the heart rate, which creates stress and limits our ability to recover from the previous day's heat exposure.

The researchers tracked the participants' sleep patterns using fitness activity trackers and temperature sensors installed in their bedrooms. They found that higher bedroom temperatures directly affect heart rate and stress responses during sleep.

This study is especially relevant as nighttime temperatures continue to rise due to climate change. The findings suggest that keeping your bedroom at 24°C can help reduce the risk of cardiovascular morbidity and mortality by impairing sleep and autonomic recovery.

Why It Matters

As India faces rising temperatures, this research highlights the importance of maintaining a comfortable bedroom temperature for better sleep and overall health. This is especially crucial for older adults who may be more susceptible to heat stress.

Key Facts

• The study found that keeping your bedroom at 24°C overnight can lower stress responses during sleep in older adults.
• Higher bedroom temperatures directly affect heart rate and stress responses during sleep.
• Climate change is increasing the frequency of hot nights, which may contribute to cardiovascular morbidity and mortality by impairing sleep and autonomic recovery.
• The study suggests that maintaining a bedroom temperature of 24°C can help reduce the risk of cardiovascular morbidity and mortality.

Key Terms
