Hidden Signs of Dehydration That Aren't Just Thirst

41. Weakened Hair and Hair Loss

Your hair is a visible indicator of your internal health, and dehydration can have a surprising effect on its strength and appearance. Your hair follicles require a steady supply of nutrients and moisture to produce healthy hair. When you're dehydrated, your body prioritizes vital organs over less critical functions, like hair growth. This can lead to a reduction in blood flow to the scalp, causing hair to become brittle, dry, and prone to breakage. In some cases, it can even contribute to hair loss. Adequate hydration is a simple, foundational step for a healthy scalp and strong, vibrant hair.

42. Dry or Sticky Gums

Another subtle sign of dehydration is the condition of your gums. When you're well-hydrated, your gums should appear pink, firm, and moist. However, when you're dehydrated, your salivary glands can't produce enough saliva to keep your gums hydrated. This can cause them to become dry, sticky, or even inflamed. Dry gums are a perfect breeding ground for bacteria, which can increase the risk of gum disease and other oral health issues. Noticing this sticky sensation is a clear signal that your body is in need of fluid.
