Tag: Sugar and thirst

According to health experts, the reason sweet treats make you thirsty is a spike in blood sugar levels. The simple and direct answer is yes, sugar makes you drink more by triggering a series of physiological responses that signal dehydration to the brain. This effect is a vital part of your body's complex system for maintaining balance.

According to research, a mere 2–3% increase in blood osmolality is enough to trigger the brain's thirst mechanism. This often explains why you find yourself reaching for a glass of water after enjoying a meal, as the composition of certain foods directly affects your body's fluid balance.
