Over two-thirds of the human body is composed of water, highlighting its critical role in maintaining bodily functions. A lack of thirst, a condition known as adipsia or hypodipsia, can disrupt this essential balance and lead to severe dehydration and health complications.

According to the National Academy of Medicine, most men need about 13 cups and women 9 cups of fluid per day, yet many find themselves wondering, "Why doesn't my body crave water?". A blunted thirst response can be surprisingly common and result from various physiological and behavioral reasons, not all of which are cause for alarm.

According to research, the human body is comprised of approximately 55% to 65% water, yet many people do not drink enough fluids daily. A significant health concern arises when you find yourself asking, "Why do I not feel thirsty anymore?". This loss of a fundamental bodily signal can lead to chronic dehydration and serious health complications if not addressed properly.

According to the National Academies of Sciences, Engineering, and Medicine, daily fluid intake recommendations vary widely by age, gender, and other factors, affirming that the question 'Does water intake depend on age?' has a definitive 'yes' as its answer. While the average adult needs about 11.5 to 15.5 cups of fluid daily, an infant's requirements are vastly different, highlighting how hydration needs change throughout the lifespan. This guide will explain why this is the case and what you should know for each life stage.
