Sleep quality depends not only on how long you rest but also on your environment — especially temperature.
When your room is too hot or too cold, it can disrupt your body’s natural sleep cycle and reduce restfulness.
Experts recommend keeping the bedroom between 60 and 67°F (15–19°C) for optimal sleep. This range supports your
body’s natural cooling process, helping you reach deeper, more restorative stages of rest. However,
many people rely on fans, which don’t actually lower room temperature — they just circulate air.
On warm nights, fans may leave you overheated and sweaty; on cooler nights, they can make the
room uncomfortably cold, preventing proper temperature regulation during deep or REM sleep.
To create the ideal sleep environment, use breathable materials like cotton or linen and consider
a cooling mattress that improves airflow. If you enjoy the sound of a fan, try a white noise machine
or humidifier instead. These provide soothing background noise or moisture without disturbing temperature balance.
By adjusting your surroundings for comfort, you’ll promote deeper, more consistent sleep — waking up feeling refreshed, energized, and ready to start the day.
