The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its origin in hot springs. [1] [2] Humans have made use of hot springs for bathing, relaxation, or medical therapy for thousands of years.
The general effects of radon to the human body are caused by its radioactivity and consequent risk of radiation-induced cancer. Lung cancer is the only observed consequence of high concentration radon exposures; both human and animal studies indicate that the lung and respiratory system are the primary targets of radon daughter-induced toxicity ...
Humans inhabit hot climates, both dry and humid, and have done so for millions of years. Selective use of clothing and technological inventions such as air conditioning allows humans to live in hot climates. One example is the Chaamba, who live in the Sahara Desert. They wear clothing that traps air in between skin and the clothes, preventing ...

The Latin phrase sanitas per aquam means "health through water", involving the treatment of disease and various ailments by balneotherapy in natural hot springs. [2]
Mineral dust is mainly constituted of the oxides (SiO 2, Al 2 O 3, FeO, Fe 2 O 3, CaO, and others) and carbonates (CaCO 3, MgCO 3) that constitute the Earth's crust.The composition of mineral dust, usually named in atmospheric sciences as mineralogy composition, is relevant for different physical and chemical processes in the atmosphere, for example, oxides with iron have an effect in the ...
