S WE MOVE INTO SUMMER WHEN WORKING AND
playing in the heat are unavoidable, let’s
examine how dehydration affects our
bodies and make adjustments.
Dehydration is a condition in which ;uid
leaves the body faster than the body can absorb
it. We lose water when we breathe, sweat and
urinate. Disease and certain medications can
contribute to ;uid loss, as can variations in diet.
Humans can survive a month or so without
food, but without water to drink, human survival
time plummets to about a week.
That makes sense, given that the average
human body is 75 percent water. Broken down,
blood is 92 percent, bones are 22 percent and
muscles are 75 percent water. Human existence
depends on water intake.
Water is one of the most vital energy sources
available. Dehydration slows enzyme activity
within the body and, in extreme cases, causes
enzyme activity to shut down completely. This
lack of enzyme production leads to tiredness and
fatigue. It’s not just the lazy days of summer.
Many people don’t realize that a fully hydrated body is essential for heart health.
