Pros: Dr. Natalie Dautovich from the National Sleep Foundation says we humans feel vulnerable in bed and while we’re sleeping… So having an animal nearby can make us feel more secure. Pets also lower our blood pressure and calm our nerves, so we have an easier time drifting off. Plus, if you’re single, snuggling up with a pet provides the same feel-good dose of oxytocin that we get from cuddling with a partner.

So what about the cons of sleeping with your pet? On the relationship front, animals create a physical barrier between you, so you’re less likely to kiss and cuddle each other – and more likely to cuddle your pet. That’s according to marriage and family therapist Dr. Kat Van Kirk. Plus, if you have allergies, you’re getting up close and personal for 8 hours with dirt, dander, pollen, mold and dust mites – all from your pet’s fur. Which can greatly increase your allergy symptoms.
