To improve sleep quality, keeping your room at the right temperature is essential. According to Dr. Kelvas, extreme heat or cold disrupts hormone regulation and leads to restless nights. The Sleep Foundation recommends a temperature between 60°F and 68°F (15.5°C–20°C). This range supports the body’s natural thermoregulation process.

As bedtime approaches, your core body temperature naturally drops, signaling it’s time to sleep. A cooler room helps this transition and promotes deeper rest. Dr. Valerie Cacho explains that cool environments increase melatonin production. This hormone is key in helping the body wind down.
