How Polar Bears Stay Warm in -50°F - Arctic survival adaptations

Dr. Joe, M.D. on Instagram: "The ‘death triangle’ is the area between your nose and the corners of your mouth. The veins here connect back to a space at the base of your skull called the cavernous sinus. Because these veins don’t have valves, infection from a popped pimple can spread backward, leading to clots, meningitis, or even brain abscesses. Safer options? Pimple patches, warm compresses, or seeing a dermatologist. Hands off this zone. 🚫👆 #MedicalFacts #SkinHealth #pimplepopping #acne"
