Ever feel exhausted but wide awake because you’re too warm at night?
It’s not just discomfort. It’s biology.
Your brain needs a small drop in core body temperature to fall asleep. When you’re too warm in bed, that signal gets blurred. 🌡️
Heat can increase heart rate and nervous system arousal, making your brain feel alert instead of sleepy.
That’s why sleep can feel harder when:
- You’re overheating under blankets
- Hormones trigger night sweats
- Anxiety raises body temperature
- The room stays too warm
Here’s the nuance:
Warmth on the outside can support sleep, while a cooler core helps your brain switch off. 💛
Think warm socks, a cozy blanket over your legs, or a warm shower as long as your body has time to cool down afterward.
