📚 The study

A recent study conducted by Baniassadi et al. (2023) sheds light on the crucial relationship between bedroom temperature and sleep quality in older adults.
The objective was to explore how varying indoor temperatures affect sleep patterns, with 50 participants monitored in their homes over several months.
The findings revealed a striking correlation: as the indoor temperature increased from approximately 25 to 30 °C, sleep quality declined by up to 10%, a statistically significant change (p < 0.05).
This decline in sleep quality underscores the importance of a cooler ambient environment, which not only promotes deeper sleep but also enhances mood resilience.
Why does this matter? Improving sleep quality by just 10% can lead to significant improvements in daily functioning and mood.
In fact, better sleep can result in a remarkable 20% reduction in daytime fatigue and irritability.
For older adults, maintaining an optimal bedroom temperature is not just a comfort issue; it may also decrease the risk of sleep disorders, paving the way for healthier, more restorative rest.
Therefore, adjusting your bedroom temperature could be a simple yet effective strategy to enhance overall well-being and quality of life for older adults.
