The debate on the optimal sleeping environment has gained attention with the focus on health implications and rising energy costs. Doctor Elizabeth Hawkes raised concerns about the adverse effects of central heating, including its impact on the body’s production of melatonin and cortisol. Research cited by the National Library of Medicine underlines the health, mood, and ageing benefits of cooler sleeping conditions.

Sleeping in cooler rooms is associated with increased melatonin production, which has potential benefits for menstrual cycles, mood, weight loss, and cancer prevention. Moreover, a cooler sleeping environment allows the body’s core temperature to decrease, facilitating better quality sleep phases like REM and deep sleep.

Additionally, cooler sleeping conditions may contribute to stress reduction by lowering cortisol production. Chronic stress can lead to serious health issues, underscoring the importance of quality sleep. Cooler room temperatures are also linked to enhanced insulin sensitivity and improved tissue health, which may decrease disease risk. However, experts advise caution in excessively cooling rooms for the elderly or individuals with specific health conditions.
