Adjust bedroom temperature
A cooler room promotes faster sleep onset and improves mood.
What You'll Do
Set your bedroom thermostat to 18 °C (64 °F) to create an optimal sleep environment.
Scientific Basis
Ensuring ambient temperature drops 1–2 °C before bedtime shortens sleep onset by ~20 minutes (~25%), supporting mood via entrained circadian cooling.

Improving sleep onset time can enhance overall sleep quality, leading to better cognitive function and mood.
A reduction in sleep latency by 20 minutes can significantly improve emotional well-being and daily functioning.
Facilitating natural cooling in the bedroom may reduce insomnia symptoms in individuals with sleep disorders.
Pro Tips
Set your bedroom thermostat to 18 °C (64 °F) for optimal sleep conditions.
Use breathable bedding materials to enhance cooling effects during sleep.
Limit screen time at least 1 hour before bed to support natural circadian rhythms.
