Conversely, a warmer room can hinder REM sleep, where dreaming occurs, and slow-wave sleep (SWS), which is vital for physical recovery, by increasing wakefulness and disrupting sleep.
Research indicates that a cooler sleeping environment might also support weight management by activating brown fat, which burns more calories, and could lower the risk of metabolic conditions like type 2 diabetes. Additionally, a cool room ensures access to all restorative stages of sleep, which is essential for overall health.
For those without a thermostat, taking a warm bath or shower before bed can help lower body temperature, thereby improving sleep quality. Incorporating these practices can lead to better rest and overall well-being.
