Squirrels That Can Sleep for 6 Months Without Water – The True Masters of “Do Not Disturb” Mode

 If you think you’re good at sleeping in on weekends, let me introduce you to your ultimate rival: the striped ground squirrel of North America. These little furballs can snooze underground for six to eight months straight—without eating, without drinking, and without even checking Instagram once. Legendary.

The Winter Hideout

While we humans panic-buy snacks and blankets the moment temperatures drop, ground squirrels simply dig themselves a cozy bunker and activate what can only be described as Ultra Sleep Mode. During this time:

• Their body temperature drops to a chilly 2–4°C, basically turning them into fluffy ice cubes.

• Their metabolism slows so much you’d think they were auditioning for a role as Sleeping Beauty’s stunt double.

• Most importantly, they completely skip meals and drinks for half the year. Not even a sip of pumpkin spice latte.

No Water, No Problem

Here’s the wild part: scientists discovered these squirrels don’t just avoid food; they also suppress the feeling of thirst. Their brains literally turn off the “I’m thirsty” alarm that keeps the rest of us chugging water bottles. Hormones like oxytocin and vasopressin help them store water like pros, and instead of heading out for a drink, they just keep snoozing.

Why? Because going outside in winter equals instant danger. Hungry predators are lurking, and no one wants to become “fast food” for a coyote while searching for a sip of water.

Tiny Scientists in Disguise

During hibernation, squirrels alternate between long naps (2–3 weeks at a time) and short wake-ups. But even when they’re awake, they still don’t touch water. Instead, researchers found they actually prefer salty solutions—it’s their body’s way of balancing fluids without diluting important ions. Translation: they’re better at chemistry than most of us were in high school.

Why Should We Care?

Beyond being adorable overachievers at napping, these squirrels might help humans someday. If we could copy their tricks:

• Medicine: Surgeons could “pause” patients during transplants or heart surgeries.

• Space Travel: Imagine astronauts snoozing their way to Mars instead of awkwardly floating around playing chess for six months.

The Real Lesson

So next time someone calls you lazy for sleeping in, tell them you’re just “practicing advanced squirrel biology.” After all, if squirrels can sleep half the year and still survive, maybe the rest of us deserve an extra Sunday nap without guilt.
