Hidden Signs of Dehydration That Aren't Just Thirst

33. Unexplained Change in Body Odor

If you've noticed a change in your body odor, even with good hygiene, dehydration could be the surprising reason. When your body is properly hydrated, sweat is mostly water. When you're dehydrated, the concentration of waste products and bacteria in your sweat increases, leading to a stronger, more pungent odor. It's a clear signal that your body's natural detoxification and cooling systems are not running efficiently. Before reaching for a new deodorant, try increasing your water intake. Sometimes, the issue isn't the product—it's your internal chemistry.

34. A Lack of Appetite

Your body's signals for hunger and thirst are regulated by the same part of the brain. When you're dehydrated, these signals can get crossed, and your brain might prioritize survival functions, suppressing feelings of hunger to conserve water. This can lead to a decreased interest in food and a feeling of being full even after eating very little. Before you skip a meal, try a glass of water. It might be the only thing your body is truly asking for.
