Chronic dehydration can have several health implications, including reduced cognitive function, impaired physical performance, and increased risk of kidney stones. Dehydration can lead to issues such as fatigue, headaches, and decreased exercise endurance. In severe cases, it may cause electrolyte imbalances, heat-related illnesses, and more serious complications. Maintaining proper hydration is critical for overall health, focusing on consistent fluid intake throughout the day, especially in hot climates or during intense physical activity.
