The science, gently
- A hibernating ground squirrel's heart can slow from hundreds of beats a minute to just a few.
- Bears live all winter on stored fat, and some do not eat or drink for months.
- Hibernation is not ordinary sleep; it is a deeper energy-saving state called torpor.
Wonder together
- If you could hibernate, what would you want to wake up to?
- What does your body do in winter that it skips in summer?
- How slow do you think your breath can comfortably go?
Tonight's calm-down
Dim yourself like a lamp on a dial: soften your jaw, then your shoulders, then your hands, then your breath, each one a notch lower. You do not need winter's slowness, just tonight's.

There's so much more to explore.
The episode is a whole story on its own. But if the wondering keeps going after the audio ends, the Family Guide opens this one all the way up: the same calm voice, turned into something you can do together at the table the next morning.
