Water is vital for each process within our body. From controlling body temperature to aiding digestion and ensuring well-functioning organs, water is essential to overall well-being. If the body is losing much more fluids that it absorbs, it causes dehydration. Even mild dehydration can impact your physical endurance, the level of energy, and mental focus. Severe dehydration could be hazardous and requires immediate medical attention.
Knowing how dehydration affects your body can help you avoid serious health issues and boost your general health and well-being.
What is Dehydration?
Dehydration occurs when the body doesn’t have enough water to function normally. The body constantly loses fluids by sweating, urinating, breathing, and digestion. The body must replenish these fluids frequently with water and other healthy liquids.
