You’ve probably heard of getting unusual bruises from nowhere. No? Well let me explain.
In extreme sudden temperature changes, the capillaries just under the skin tend to burst and what results is a mess that nobody would want. Allowing your skin a 30 minute grace period solves this problem. Between bathing and going out to the frigid weather, an extremely hot and extremely cold exposure to the skin wears out our skin pretty quickly. By slowly letting your skin adjust itself to the room temperature, the gap between the two extremes is lessened and less stress is exerted on the skin’s delicate capillaries.
