Cold vs Warm Sleep: Is 68 Degrees Good for Sleeping?

Bedroom temperature can have a noticeable effect on how well you sleep. If the room is too warm, you may find yourself tossing and turning. If it's too cold, you might wake up in the middle of the night looking for another blanket. So what temperature works best for sleep, and is 68°F (20°C) a good place to start? Read on to find out what makes a comfortable sleep environment and how to achieve it at home.

Is 68 Degrees Good for Sleeping?

Yes, 68°F (20°C) can be a comfortable sleeping temperature, although the ideal setting varies from person to person. Your core body temperature naturally drops as you prepare for sleep, and a slightly cool bedroom can help your body release excess heat.

Keeping your bedroom around 68°F may also help reduce overheating and other temperature-related discomfort, helping you stay comfortable throughout the night.

Is It Better to Sleep Cold or Warm?

A slightly cool bedroom is generally more comfortable for sleep than a warm one, although going too cold can also be disruptive. For many adults, a practical approach is to keep the bedroom around 60–68°F (16–20°C) and adjust based on personal comfort, bedding, and the season. Temperatures that feel too warm or too cold may make it harder to sleep comfortably through the night.

When the Bedroom Is Too Warm

• Difficulty falling asleep: Your core body temperature naturally drops before sleep, and an overly warm room can make it harder for your body to release heat.
• Restless sleep: Overheating or sweating can make it harder to stay comfortable and may leave you tossing and turning during the night.
• Lower sleep quality: Excessive heat has been associated with poorer sleep quality and changes in sleep stages.
• Thirst and discomfort: Hot conditions can increase sweating, leaving you thirsty or uncomfortable during the night.

When the Bedroom Is Too Cold

• Difficulty falling asleep: An overly cold room can make it harder to relax and settle into sleep.
• Muscle tension and discomfort: Feeling too cold may leave your body tense or uncomfortable, especially if you're not warm enough in bed.
• Dry air: Cold outdoor air and indoor heating can lower indoor humidity, potentially causing dry skin, lips, throat, or nasal passages.
• Reduced comfort: Drafts, cold bedding, or temperature changes during the night can disturb your comfort and make it harder to stay asleep.

How to Keep Your Bedroom at the Ideal Temperature for Sleeping?

• On mild nights with good outdoor air quality, open a window to bring in fresh air and let excess heat escape.
• When outdoor temperatures are high, air conditioning can help keep the bedroom comfortably cool.
• In winter, a heater can keep the bedroom from getting too cold, especially if your central HVAC warms the rest of the house but leaves your bedroom chilly.
