How your body cope with the change of water intake?

When water intake changes, the body adapts by regulating fluid balance through mechanisms like thirst and urine production. Increased water intake prompts the kidneys to excrete more urine to maintain homeostasis, while decreased intake leads to reduced urine output and heightened thirst to encourage hydration. Hormones such as antidiuretic hormone (ADH) also play a crucial role in managing water retention or release based on hydration levels. Overall, these responses help maintain the body's optimal fluid balance.
