Hidden Signs of Dehydration That Aren't Just Thirst

61. Difficulty Regulating Body Temperature

Dehydration can paradoxically lead to issues with both hot and cold sensations. When you're dehydrated, your body's ability to sweat—a crucial mechanism for cooling down—is compromised. This can cause your core body temperature to rise, making you feel uncomfortably hot and flushed. At the same time, a lack of fluid can impair circulation, causing you to feel colder than usual in your hands and feet. If your body's internal thermostat seems out of whack, a lack of water is a very likely culprit.

62. Chronic Bad Breath

Bad breath, or halitosis, is an unpleasant condition that can be directly linked to dehydration. Saliva is your body's natural mouthwash; it helps wash away food particles and bacteria that cause foul odors. When you're dehydrated, your salivary glands can't produce enough saliva, leading to a dry mouth where bacteria can thrive and multiply. If you've tried brushing, flossing, and mouthwash without success, your breath may be a signal that you need to increase your fluid intake to restore proper saliva production.
