Question

What is the best temperature for sleeping in winter?

Answer from HVAC IQ

The ideal bedroom temperature for winter sleeping is between 60-67°F (15.5-19.5°C), with most sleep experts recommending around 65°F (18°C) for optimal rest.

Your body naturally drops its core temperature as you prepare for sleep, and a cooler room helps facilitate this process. When your bedroom is too warm, it can interfere with your body's natural temperature regulation and lead to restless, interrupted sleep. The 60-67°F range allows your body to cool down properly while still maintaining comfort under blankets.

Individual preferences vary within this range. Some people sleep better at the cooler end (60-62°F), while others prefer it slightly warmer (65-67°F). Factors like your bedding, sleepwear, and personal metabolism all play a role. If you share a bed, you might need to compromise or use separate blankets to accommodate different comfort levels.

In Ottawa's winter climate, maintaining consistent bedroom temperatures can be challenging with our extreme cold snaps and fluctuating outdoor temperatures. A programmable thermostat can help you automatically lower the temperature at bedtime and raise it before you wake up. This approach can also save on heating costs - lowering your home's temperature by just 7-10 degrees for 8 hours can reduce your heating bill by up to 10%.

Keep safety in mind - never let your home get so cold that pipes could freeze (generally below 55°F). If you're having trouble maintaining consistent temperatures in your bedroom, or if some rooms are much colder than others, this could indicate issues with your heating system, ductwork, or insulation that should be addressed by an HVAC professional.

Consider using extra blankets or adjusting your sleepwear rather than cranking up the heat, as this approach promotes better sleep while keeping energy costs manageable during Ottawa's long winter months.
