Sleep specialist Dr. Cathy Goldstein says it’s worse to be too hot!
That’s because our core temperature needs to drop to trigger our sleep hormones. So if we’re too hot, our body thinks it’s not bedtime yet, so it keeps our brain alert. And if you do fall asleep when you’re too hot, you’ll miss out on slow-wave sleep – the most restorative kind. Ideally, the bedroom should be between 60 and 67 degrees. That’s the optimal temperature for sleep.
