Aquarian Industries offer hydration test kits which will help identify when an individual is dehydrated or becoming dehydrated. When a person does not drink enough water or loses large amounts of fluids because of diarrhoea, vomiting, sweating, or strenuous exercise, dehydration can occur. When the body becomes dehydrated, it reabsorbs fluid from the blood and other body tissues. If a person is severely dehydrated, there is no longer enough fluid in the body to get blood to the vital organs and the person may begin to go into shock. Severe dehydration and shock are life threatening.
