Hot springs are natural springs where hot water rises from underground. They are formed when hot rocks deep underground allow water to be heated above normal body temperature. Taiwan has several natural hot springs, such as Reef Brook and Yangmingshan National Park. Hot springs can be of different types, like pure, sulfur, or salt springs. Visiting hot springs provides health benefits and helps prevent illness by keeping people young. Hot springs should be treasured globally so they can be enjoyed for a long time.
