I found this on WebMD and thought under the circumstances I should post it:
"What are the symptoms of heat exhaustion?
Individuals with heat exhaustion tend to have symptoms such as:
profuse sweating,
weakness,
muscle cramps,
headache, and
nausea and vomiting.
As dehydration increases from the loss of body water, lightheadedness may occur and fainting (syncope) may occur especially, if the affected individual stands up quickly (orthostatic hypotension). A low grade fever also may be present.
When should an individual seek medical care for heat exhaustion
Heat exhaustion usually can be treated at home as long as the affected individual can maintain proper hydration. Water, electrolyte replacement solutions or sport drinks are appropriate to consume. If nausea and vomiting prevent rehydration, the individual should seek medical attention.
Muscles cramps can be severe and if stretching and rehydration cannot relieve recurrent cramps, medical care may be necessary.
It is important to recognize that if the person stops sweating, becomes confused, or has a seizure, heat stroke, a life-threatening condition, may be developing. Emergency medical services should be activated immediately (call 911 if available) and move the affected individual to a cooler place, remove their clothing, and try to cool the body with cold compresses, ice, and oscillating fans.
How is heat exhaustion diagnosed?
Diagnosis of heat exhaustion is made by circumstantial evidence:
1.history (exercising or working in a hot environment)
2.symptoms (excess sweating, headache, weakness, nausea and vomiting)
3.physical examination (signs of dehydration)
Laboratory tests are not mandatory unless the health care practitioner is concerned about electrolyte imbalance or significant dehydration.
However, it is important for the health care practitioner to consider other diagnoses, since there are many infectious illnesses that accompany a fever, weakness, nausea and vomiting. This is especially the case in the elderly and very young. In these groups, heat exhaustion may be a diagnosis of exclusion, meaning that other more serious illnesses should be considered before settling on heat as the cause of the problem. Careful history and physical examination may be all that is needed."
On the worst day in June I also noticed along with leg cramps, I didn't need to use the rest room. I think my body used all the liquid I drank to rehydrate and sweat(My clothes were WET with sweat... not damp WET). It wasn't until I was home and had cooled off for a few hours and drank more Gatorade that I needed to "go". SO, if you aren't used to the heat, read the above symptoms and keep a close eye out on your loved ones if possible. And keep your sense of humour... the heat can't last. If you Google Heat Exhaustion on WebMD you can find the entire article. Might be a good read for all of us in this heat wave.
