As the days are longer and the desire to work outside in the garden, yard and even at the beach it is important to recognize the symptoms of dehydration.
The human body is 70% water and as little as 2% loss of water can result in problems in humans (animals as well).
Our bodies need water for lubrication, digestion and expelling toxins. If the body lacks water, all systems of the body are affected.
The average adult uses 2 - 3 liters of water a day due to non-exercise, normal use. The more activities a person dies, the more liquids will need to be replenished. Each body is different, so one person might need more water than another.
Symptoms appear initially are as mundane as thirst and dry mouth. Other symptoms include loss of appetite, dark colored urine, fatigue, chills and headache.
It the dehydration continues further to 5% water loss, serious effects include increased heart rate, decreased sweating, muscle cramps, increased body temperature and nausea.
Heatstroke is the next on the list of problems.
One test to see if you are dehydrated is to pinch the skin on the top of your hand. If it stays in place (pinched and doesn't return to 100% normal shape) you are dehydrated. This test can be used on children as well.
By the time you feel thirsty, you are already dehydrated, so try to drink more fluids on hot days, as well as before you start physical activity.
