What Is the Ideal Sleeping Temperature for My Bedroom?

The short answer from a sleep psychologist

Q: What is the optimal sleep temperature, and why?

A: Typically it is suggested that the temperature in the bedroom for adults should be between 60 and 67 degrees Farenheit for optimal sleep. Your body temperature decreases as part of the sleep initiation process, and this range of temperature is thought to actually help facilitate this decrease.

It can be useful to think of the bedroom as your “cave” — it should be cool, dark and quiet to enhance your sleep.

If the bedroom becomes uncomfortably hot or cold, you are more likely to wake up, and the comfort level of the bedroom temperature especially impacts the quality of rapid eye movement (REM) sleep, the stage in which one dreams.

The best sleeping temperature for babies and toddlers is a bit higher, between 65 and 70 degrees.
