The document summarizes environmental conditions and survival strategies in Antarctica. Temperatures can drop as low as -129°F with winds up to 200 mph and less than an inch of precipitation annually. To survive, it is crucial to wear many loose layers of thermal underwear, jackets, pants, and a parka. Additional necessities include a high calorie diet, lip balm, sunscreen, and sunglasses. Physiologically, the body responds to cold by shivering to generate heat, pumping blood faster to the core, and limiting circulation to limbs to retain core warmth. Layers trap air for insulation so heat is not lost through the head and limbs, preventing frostbite.
