We usually feel thirsty after eating salty food; because salt is a solute and after consuming lots of salt, our cells become concentrated with salt, which triggers the process of thirst. Osmosis plays a major role in the chemistry of living things and also has applications in medicine and technology. If you store contacts in distilled water, the salt concentration is higher in the eye fluid and water flows out of the contacts; slowly drying them out. AJNR Am J Neuroradiol.
