Thirst is the body's initial signal of dehydration. Feeling thirsty means that the body has already started to dehydrate.
When dehydrated, urine output decreases, and the color of the urine may become darker, ranging from deep yellow to amber.
Dehydration may cause the skin to lose its elasticity, making it slower to return to its normal position after being pinched.
Inadequate hydration can affect energy levels, leading to feelings of fatigue and weakness.
Severe dehydration can impair cognitive function, resulting in mental confusion or difficulty concentrating.
Due to an imbalance in electrolytes, dehydration may cause muscle cramps or spasms.
To compensate for the drop in blood pressure, the heart may beat faster to maintain circulation.
