Get a comfortable bedroom temperature range to try, based on the widely cited ~60–67°F guideline and adjusted for how hot or cold you tend to sleep.
Many sleep resources point to a comfortable bedroom range of roughly 60–67°F (about 15.6–19.4°C) for adults, with the mid-60s°F often cited as a common starting point. This tool centers on that range and nudges it cooler or warmer depending on whether you sleep hot or cold, then gives you a target range to experiment from.
Temperature preference is personal and also depends on bedding, sleepwear, humidity and airflow. Use the suggestion as a starting point, not a strict rule, and adjust based on how you actually feel over a few nights.
A widely cited comfortable range for most adults is roughly 60–67°F (about 15.6–19.4°C), with many sources pointing to the mid-60s°F as a common sweet spot. Personal preference and bedding matter, so treat it as a starting point to experiment from.
Nurseries are often kept a little warmer, commonly around 68–72°F (20–22°C). Always follow current pediatric safe-sleep guidance and dress the baby appropriately rather than relying on temperature alone.
Your body temperature naturally dips as you fall asleep, and a cooler room supports that process for many people. This tool is educational and offers general comfort guidance, not medical advice.
Try breathable, moisture-wicking bedding and sleepwear, reduce heavy layers, improve airflow, and keep the room dark. Our cooling-bedding guide covers practical options for hot sleepers.
