Final answer:
To assess hydration status, weighing before and after exercise, monitoring saliva production, and observing the color of urine are effective indicators. Physical changes in the body as a response to dehydration trigger thirst and involve ADH in regulating kidney function.
Step-by-step explanation:
When it comes to assessing hydration status, certain indicators can provide valuable information. The correct statements regarding how to assess hydration status are:
- Weighing the body before and after exercise can be used to detect overhydration and dehydration due to changes in body water content.
- Reduced saliva production can be an indicator of dehydration, signaling a decrease in serous output and an increase in thicker mucus, resulting in a dry mouth sensation.
- Dark urine can be an indicator of a water imbalance, as the kidneys concentrate or dilute urine based on the body's hydration levels.
These methods are part of a broader understanding of dehydration and hydration management. Dehydration occurs when water loss exceeds intake and is signalled by physiological responses such as increased blood osmolality, which triggers the thirst response. Also, the antidiuretic hormone (ADH) plays an essential role in the regulation of body water levels by signaling the kidneys to recover water from urine.
