Saliva helps clean your mouth and fight bacteria. When you’re dehydrated, saliva production drops, leading to dry mouth and an increase in bad breath.
DARK YELLOW URINE
One of the easiest ways to check for dehydration is by looking at the color of your urine. Dark yellow or amber urine typically means your body is low on water.
FATIGUE AND LOW ENERGY
Even mild dehydration can cause tiredness, sluggishness, and lack of focus. Your body needs adequate fluids to maintain energy levels and regulate internal systems.
DIZZINESS OR LIGHTHEADEDNESS
Lack of water can lower your blood pressure, reducing the flow of oxygen to the brain and causing dizziness or feeling faint.
HEADACHES
Dehydration is a common trigger for headaches and even migraines. If you frequently experience unexplained headaches, try increasing your water intake.
DRY SKIN AND EYES
When dehydrated, your skin may lose elasticity and become dry or flaky. Your eyes might feel irritated, dry, or appear sunken.
CONSTIPATION
Water is essential for healthy digestion. Insufficient hydration slows bowel movements and can cause constipation and bloating.
INCREASED HEART RATE
Dehydration reduces blood volume, forcing your heart to work harder to pump blood. This may result in a rapid heartbeat or palpitations.
