With brand-name bottle fads and gallon-a-day water challenges trending on TikTok, hydration is in, and that’s good news for health. The average human body is more than 60% water. Water makes up ...
But a 2022 study published in Science casts doubt on whether people need to drink that much water. “Most people will find that they don’t need eight glasses per day,” Herman Pontzer, co ...

Research involved people drinking a glass of water in which some of the hydrogen molecules were replaced by a stable isotope of the element called deuterium, which is found naturally in the human ...
Overview. The water molecule, in the gaseous state, has three types of transition that can give rise to absorption of electromagnetic radiation: Rotational transitions, in which the molecule gains a quantum of rotational energy. Atmospheric water vapour at ambient temperature and pressure gives rise to absorption in the far-infrared region of ...
