The Basics of Hydration and Dehydration

The causes of dehydration may be different between athletes and astronauts,
but human physiology and the results are the same. . .   
So, The Right Stuff
® is outstanding for both! 

Dehydration Basics:
  • We all have hydration receptors throughout our body (both within the cells and extra-cellular)
  • These receptors ensure our bodies maintain homeostasis or  equilibrium (prevent dehydration)
  • There are many causes of dehydration including, but not limited to: exercise, altitude, low humidity environments, heat exposure and illness
  • There are three, generally accepted, stages of dehydration:
    • Mild (loss of 3-5% of body weight)
    • Moderate (6-9%)
    • Severe (10% or more)
Various scientific studies suggest that as little as a 2% decline in hydration can result in up to a 10% reduction in athletic performance.

With moderate dehydration (which includes changes in sodium levels), side effects can include:

  • Headaches, dizziness or light-headedness
  • Muscles cramping
  • Thirst or dry mouth
  • Fatigue 
  • Deep or rapid breathing
  • Low blood pressure and/or weak pulse
  • Temperature drop (especially the extremities)
  • Dry eyes
  • Confusion
The Right Stuff can help prevent and alleviate the symptoms  associated with dehydration!
