Summary:
- Thirst is not a reliable indicator of dehydration. Thirst is a subjective sensation that can be influenced by various factors, including age, medications, and underlying health conditions.
- Factors like urine color, skin elasticity, and heart rate may provide more objective measures of hydration status. However, these can also be affected by factors other than just dehydration.
- The best way to assess hydration is through a combination of different measures, including thirst, urine output, and blood tests. Relying solely on thirst can lead to under- or over-hydration.
