Our core temperature needs to drop to trigger our sleep hormones. If we’re too hot, our body doesn't think it’s time to go to sleep yet, so it keeps our brain alert. Ideally, the bedroom should be 19 degrees (67F) - the optimal temperature for sleep.
I have an air conditioner in the bedroom mostly for the sound so I don't hear anything in the night but the temperature gets to about 66°. If it gets 70 or above I wake up a sweaty mess ! ...Nytol! 55 days ago
