Heat exhaustion is less dangerous, but can present with muscle cramps, headaches, dizziness, weakness, fatigue, nausea and vomiting. There are other heat illnesses, too, not to mention Below, Dr. Waters shares ways you can prevent heat exhaustion and heat stroke by recognizing the symptoms and responding appropriately. Are heat stroke and heat exhaustion the same? “People often talk about heat exhaustion and heat stroke as though they are separate things. But they exist on a spectrum from not-so-serious to a significant and life-threatening emergency,” Dr. Waters says. The spectrum of heat-related illnesses includes: • Heat rash: Also known as prickly heat, • Heat cramps: Painful muscle cramps can strike when you’re • Heat exhaustion:More serious than heat rash or cramps, heat exhaustion occurs when your body can’t cool itself through sweating. Untreated, it can progress to heatstroke. • Heat stroke:Sometimes called sunstroke, heatstroke is the most severe heat-related illness. During...

What Are The Causes Of Heat Syncope? Heat Syncope as stated is caused due to excessive dilation of the blood vessels in order to cool the body in a hot environment causing reduced blood flow to the brain. Apart from this, Heat Syncope can also be caused as a result of blood collecting in the legs if an individual is standing for an extended period of time in the hot sun or as a result of doing rigorous physical activity for an extended amount of time out in the sun. The risk for developing magnifies if the individual has not had proper fluid intake before going out in the sun or has not adjusted to the hot climatic condition. The recovery period from Heat Syncope is rather fast after the affected individual is shifted to a cooler place. Sometimes, Heat Syncope is caused as a result of some type of What Are Treatments For Heat Syncope? Heat Syncope basically does not require any aggressive treatment. Simple basic steps as mentioned below can be followed to treat Heat Syncope: • Lie down at a cool place, preferably in an air conditioned area. • Keep the feet elevated. • Drink fluids rich in electrolytes to maintain electrolyte balance. • Avoid strenuous activities in hot weather. Some Measures Which Can Be Taken To Prevent Heat Syncope Are: • Try and avoid extremely hot weather condition especially if not appropriately acclimatized. • If affected with Heat Syncope, immediately move to a cooler place so that the body cools down. • Try and avoid • Maintain adequate intake of f...

There are many types of heat injury, ranging from mild heat cramps to life-threatening heat stroke. A growing number of children and young adults are playing sports during late summer and early fall. According to the Centers for Disease Control and Prevention, heat illness during practice or competition is a leading cause of death and disability among U.S. high school athletes. As more people exercise in warm conditions, it's essential to take proper precautions. © Thinkstock 2016 Heat-related illnesses are preventable. Prevention begins with understanding the causes of heat illness, and making sure to stay cool and hydrated during hot weather. In addition, knowing the signs of heat injury and being able to treat it immediately will reduce the number of severe cases. Cause When we exercise, our bodies cool off by sweating. As we perspire, we lose necessary body fluids. If we do not replace these fluids, we become dehydrated. This makes it difficult to sweat and cool down, which can result in a heat injury. During regular exercise, 70 to 90% of the energy our bodies produce is released by heat. Many factors can hinder heat release and perspiration. These include: • Environment. Air temperature, combined with humidity, wind speed, and sun affect how well our bodies cool themselves. Humidity influences how easily sweat can evaporate. High humidity (greater than 60%) makes sweat evaporation very difficult. • Clothing. Dark clothing absorbs heat. This can dramatically increase ...

What Is Syncope? Syncope is the medical term used for fainting or passing out. An abrupt, transient reduction in blood supply to the brain causes syncopal episodes, which results in loss of awareness and motor control. The person subsequently collapses or falls, allowing blood to flow back to the brain. The person can regain consciousness once blood flow has been restored. What Is Heat Syncope? Heat What Are the Causes of Heat Syncope? Heat syncope occurs when blood pressure drops as the body dilates small blood vessels or arterioles present in the skin to radiate heat in a warm climate. Before the blood volume expands, this state continues for five days during heat acclimation. When a person stands up rapidly or for a long time, blood flow to the brain is diminished, resulting in light-headedness and fainting. Those who do intensive work outside in hot temperatures are more vulnerable to heat syncope. What Are the Signs and Symptoms of Heat Syncope? Heat syncope is different from • Lightheadedness or dizziness. • A brief • • • Weakness. • The pulse rate has increased. • Sweaty or pale skin. • • Vomiting. • When shifting positions, such as from a lying to a standing position, one may feel lightheadedness (orthostatic hypotension). How Is Heat Syncope Diagnosed? A physical examination is used to make the diagnosis of heat syncope. During the physical examination, the medical practitioner will check the patient's blood pressure and pulse. If the patient is suffering from hea...
