Your spine’s health depends on more than posture and exercise, hydration plays a critical role too. The spinal discs, which sit between your vertebrae, act as natural cushions absorbing daily pressure. Each disc has a gel-like center surrounded by a tougher outer ring, and the inner part is packed with water, keeping it plump, flexible, and shock-absorbent.
When your water intake is low, your body prioritises essential organs, and the discs receive less fluid. As a result, the gel center shrinks and loses its cushioning ability, reducing the space between vertebrae. This extra strain on the outer ring increases the risk of small tears and adds pressure on nearby joints and ligaments, leading to stiffness and discomfort.
