To know if you are dehydrated, look out for these common signs and symptoms:
- Thirst and dry mouth, which is often the first signal of dehydration.
- Dark-colored urine or a lower amount of urine output; ideally, urine should be pale yellow.
- Fatigue or feeling unusually tired.
- Lightheadedness, dizziness, or muscle weakness.
- Dry skin, cracked lips, and reduced skin elasticity.
- Nausea or vomiting, which can worsen dehydration.
- No sweating, lack of tears, or very little urination as dehydration becomes severe.
- In severe cases, symptoms can include confusion, rapid heartbeat, rapid breathing, sunken eyes, and fainting.
Checking urine color and volume is a practical way to assess hydration. Mild dehydration makes you thirsty and tired, while severe dehydration is dangerous and needs medical attention immediately.
