As summer finally shows its sunny rays, temperatures are rising each day and bedroom temperatures get warmer each night. A summer heat wave can result in the loss of 15 to 20 minutes of quality sleep each night. During a 2016 summer heat wave, Sleep Number's proprietary SleepIQ® technology reported that for every 10 degrees that the temperature rose above the national average, people lost an average of 3 to 4 minutes of sleep.

While there's not much you can do about the outside temperature, adjusting bedroom temperature can help you get the most out of your nightly zzz's…unless your sleep partner doesn't agree on a comfortable temperature! A recent national Omnibus survey by Sleep Number showed:

-- This topic makes millennial couples especially HOT - 44% of them (18-34 years old) discuss bedroom temperature at least once a week, while 30% of couples in other age groups report a weekly temperature discussion.

-- Summer is the season when couples most often discuss bedroom temperature, followed by Winter.


So, who is right? Sleep Number data shows we sleep best when the bedroom temperature is set around 65 degrees. Beyond just the room temperature, consider these tips for keeping both partners comfortable:

-- Take a shower before bed to warm your skin - this actually lowers your internal body temperature, which can help bring on sleepiness.

-- Swap your bedding - if you find the bed to be too warm, try 100 percent cotton bedding. Many people prefer an open weave cotton blanket.

-- Skip exercise and large meals before bed - exercising or eating before bed can raise internal body temperature, making it harder to fall asleep.

-- Take the necessary steps to keep outside heat from getting in. This might include using blinds to keep out the sunlight, or keeping the windows shut.

-- Try adding a DualTemp™ layer under the sheets. This can help both partners keep a steady temperature throughout the night.
