Hidden Signs of Dehydration That Aren't Just Thirst

45. Reduced Tolerance to Cold

While we already mentioned cold hands and feet, a more general sign of dehydration is a reduced tolerance to cold temperatures. Water is crucial for thermoregulation, helping to hold and distribute heat throughout your body. When you're dehydrated, your blood volume drops, and your body can't circulate heat as efficiently. This can make you feel colder than usual and more sensitive to chilly environments. If you're constantly shivering or reaching for a sweater while others are comfortable, it's worth considering your fluid intake.

46. Increased Body Weight

This one seems counterintuitive, but a rapid, unexplained increase in body weight can be a signal of dehydration. When your body is in a state of fluid conservation, it holds onto every drop of water it can. This leads to water retention, which can cause bloating and an increase in your weight. This is often the body's attempt to protect itself from more severe dehydration. While it may seem like you're gaining weight, it's actually just fluid that your body is storing. Rehydrating can help your body release this excess water and return to its normal weight.
