A hot spring is a natural spring of water that is heated by geothermal energy from the Earth's interior. These springs often contain minerals that can be beneficial for health and wellness. The temperature of the water can vary, but it is typically warmer than the surrounding environment, making it a popular destination for relaxation and therapeutic purposes. Hot springs can be found in various locations around the world, often in volcanic regions. They are commonly associated with geothermal activity, which occurs when magma heats underground water. Many cultures have historically used hot springs for bathing and healing, contributing to their popularity as tourist attractions.
