And a Little knowledge about How humans regulate body temperature in essence a review of the owner s manual can help prevent a breakdown in the. Less than perfect Cooling systems with which we be been endowed. A first to be Clear the body has no interest in making us comfortable it strives to keep us from overheating As a. Purely practical matter because the enzymes that regulate life s critical chemical reactions work Only within a narrow temperature Range. Quot cells work Best at about 98 degrees fahrenheit Quot said Terry Kowalenko an emergency room specialist at Henry Ford Hospital in Detroit. Quot if you get too Low reactions Stow Down. Too High and you re breaking Down proteins and cellular functions break  maintain internal temperatures within a degree or so of optimal the body has a control Center in the front part fihe hypothalamus deep within the brain. Monitored Here Are temperature signals from inner organs the skin and outer extremities. And from Here Are. Sent various electrical and chemical signals to the blood vessels endocrine glands sweat glands and musculature that instruct the body How to compensate for temperature shifts. A a. A a a As perverse As it May seem during a hot summer the body is constantly generating heat a the result of various metabolic reactions and muscle contractions. Heat is carried by the blood from the steamy streets of the body s. Interior to the cooler suburbs of the skin where it radiates naturally to surrounding air. A. That s Fine As Long As the air around the body is actually cooler than the body. But As the outside temperature climbs closer to 98 degrees meat leaves the body Ever More slowly. A the hypothalamus picks up on the problem said 1  Hamlet director of research plans and operations at the army research Institute of environmental Medicine in Natick mass. Quot it says hey the blood coming Back to the brain is warmer than it was a minute ago Quot and it sends out orders. Quot it says first i la raise the heart rate and dilate blood vessels to the skin to radiate More heat away and to give a larger surface area for heat loss Quot Hamlet said. That helps for a while. But if the outside temperature is equal to or greater than 98.6, there is simply no place for body heat to go. At that Point Hamlet said the hypothalamus tells the sweat glands to get serious. Sweating is both the key to super efficient Cooling and the first step toward collapsing from heat exhaustion. On the positive Side sweating brings to the body s refrigerate be armament rim a process known As evaporative Cooling which works even when air temperatures exceed body temperature.

But there is also a Downside to sweating the body can afford to lose Only so much water before it begins to shrivel Quot As you sweat you lose juice Quot Hamlet said. Quot the juice that s left to be pumped by the heart becomes viscous and it s not going too fast and it can t get through the Small tubes near the  in essence the body s Radiator becomes clogged and sluggish. The. Sheer Lack of fluid volume makes your blood pressure drop. Low blood pressure from water loss a exacerbated by the propensity toward lethargy in hot. Weather which eliminates the Arm and leg movements \ that would otherwise help pump blood to the brain adds up to a Lack of oxygen above the neck. And after a. While you faint. A fainting is hardly the worst thing that can happen in the heat. It s just the body s Way of getting the head on the same horizontal plane As the heart easing the Supply of blood and oxygen to the brain. The bigger problems triggered by profuse sweating Are caused not just by the loss of water but also by the loss of salts that come out with that water. 5odium, Chloride and potassium gradually get depleted As the body sweats and the body s delicate chemical and electrical balances go increasingly awry. The combination of water loss and Salt depletion can Lead to three degrees of distress hot lips for summer Here Are some tips for coping with hot weather. A drink lots of fluids preferably water or juices. Avoid caffeinated and alcoholic beverages because they reduce fluid retention. A stay indoors from midday to late afternoon the hottest time of the Day. If you must go outdoors do so in the Early morning and evening.

A Scripps Howard news services amps file a heat cramps Are an Early sign of Salt loss. Common in athletes Yho work too strenuously in hot weather the symptoms can be quickly resolved by drinking slightly salted water one Salt Tablet in a quart of water is plenty. A heat exhaustion also known As heat prostration is a More serious stage of dehydration and Salt loss symptoms include nausea vomiting and dizziness. Body temperature is generally not terribly elevated and the person is usually sweating profusely. A Teaspoon of Salt in. A quart of water May prompt recovery but a trip to the Hospital where intravenous fluids can be administered a especially if there is the possibility that the person has. Actually suffered from the More serious heatstroke a. Should be considered. \ a a a heatstroke is a life threatening collapse of major body systems in response to severe Salt and water loss and dangerously High internal temperatures. Body. A temperature is generally above 105 degrees and people a. May display bizarre behaviour ranging from irritability to combativeness. They May also lose consciousness. A a at these temperatures proteins begin to coagulate like eggs on a hot Skillet. The liver especially which stays a about one degree warmer than the rest  body s. Interior begins to break Down releasing toxins into the blood. Cell membranes and mitochondria the Energy plants inside cells collapse and fluids meant to be kept separate in the body leak into the wrong compartments. Quot almost every body system is affected Quot said Kowalenko. Quot the kidneys the liver the blood system. Immediate medical help should be summoned. In the meantime first Aid should include immediate Cooling preferably by wetting Down the body and fanning it. "but1 you Don t want to get them so cold that you make their blood vessels constrict Quot Kowalenko said which will interfere with the body s Effort to radiate heat trapped within. Quot and you Don t want to make them shiver which produces  fever busting aspirin and acetaminophen tylenol. Don t work against heatstroke Kowalenko added.
