Risk Factors Of Heat Stress

Doctors warn of heat exhaustion, heat stroke during surging temps

A number of physical and environmental conditions increase the risk of experiencing heat stress and even developing serious or life threatening medical problems in hot weather. Any of the following physical conditions increase the risk:

  • Pre-existing heart disease

A most critical environmental condition is humidity. Humidity greatly increases the risk of heat stress by directly interfering with the evaporation of sweat. Hot and humid weather is much more dangerous than hot, dry weather.

The use of certain prescription drugs which depress or interfere with the body’s natural temperature control system can also increase your risk of suffering heat stress. If you take medicine for high blood pressure, nervousness, depression, poor blood circulation, or sleeping, ask your doctor or pharmacist for advice.

Risk Factors For Heat Exhaustion

Heat exhaustion is strongly related to the heat index, which is a measurement of how hot you feel when the effects of relative humidity and air temperature are combined. A relative humidity of 60% or more hampers sweat evaporation, which hinders your body’s ability to cool itself.

The risk of heat-related illness dramatically increases when the heat index climbs to 90 degrees or more. So it’s important — especially during heat waves — to pay attention to the reported heat index, and also to remember that the heat index is even higher when you are standing in full sunshine.

If you live in an urban area, you may be especially prone to develop heat exhaustion during a prolonged heat wave, particularly if there are stagnant atmospheric conditions and poor air quality. In what is known as the “heat island effect,” asphalt and concrete store heat during the day and only gradually release it at night, resulting in higher nighttime temperatures.

Other risk factors associated with heat-related illness include:

Check with your doctor to see if your health conditions and medications are likely to affect your ability to cope with extreme heat and humidity.

Can Hot Weather Cause Diarrhea

Hot weather affects the body in several ways. The normal response is to sweat and feel mildly uncomfortable. But sometimes, the effects can be worse especially when the weather is hotter than usual such as during a heat wave.

Some people experience bouts of diarrhoea which dont seem to be linked to something they ate. Could it be related to the hot weather?

Can Medications Increase The Risk Of Heat

The risk for heat-related illness and death may increase among people using the following drugs: psychotropics, which affect psychic function, behavior, or experience medications for Parkinsons disease, because they can inhibit perspiration tranquilizers such as phenothiazines, butyrophenones, and thiozanthenes and diuretic medications or water pills that affect fluid balance in the body.

 25+ Best Memes About Heat Exhaustion

The signs of heat exhaustion include:

  • feeling sick or being sick
  • excessive sweating and skin becoming pale and clammy or getting a heat rash, but a change in skin colour can be harder to see on brown and black skin
  • cramps in the arms, legs and stomach
  • fast breathing or heartbeat
  • being very thirsty

The symptoms of heat exhaustion are often the same in adults and children, although children may become irritable too.

If someone is showing signs of heat exhaustion they need to be cooled down and given fluids.

Who Is At Risk For Heat Exhaustion

Heat exhaustion usually affects people who are working or exercising in a hot environment, and those who do not have access to adequate water. Those at risk for heat exhaustion include:

  • Infants and young children are at risk because their temperature regulation mechanisms are not fully developed. They also are dependent upon others for water and appropriate clothing.
  • The elderly are similarly at risk because of underlying medical conditions that limit the ability to sweat including poor circulation, skin changes, and chronic medication usage.
  • Socioeconomic issues increase the risk of heat exhaustion if access to air conditioning is limited. During heat waves, large cities often open cooling centers to help minimize the risk of large numbers of people succumbing to heat-related illness.
  • Certain medications such as antidepressants, antipsychotics, and tranquilizers may impair the ability of the body to sweat.
  • Alcohol consumption
  • The overweight or obese

The body has the ability to acclimate to hot weather but if heat waves come suddenly, or if a person travels from a cooler environment to a hot environment, the risk of heat exhaustion increases. It takes about 7 to 10 days for the body to adapt to hot weather. A non-acclimated person can produce a liter or almost a quart of sweat in an hour to assist in cooling the body. A person who is acclimated to the heat can produce 2 or 3 liters of sweat per hour, doubling or tripling the cooling potential for the body.

How Common Is Heat Exhaustion

Heat exhaustion and other types of heat illness are more common than you might think. Heat exhaustion from exercise happens more often on hot, humid days. Risk factors of heat exhaustion include:

  • Age: Older people and young children have a higher chance of getting heat exhaustion. People over 65 and children under four cant regulate their body temperature as easily. They are also more likely to get dehydrated .
  • Alcohol use: Dehydration can result from drinking excessive amounts of alcohol. Dehydration increases the risk of heat exhaustion. Alcohol also makes it difficult for you to control your body temperature.
  • Lifestyle: Physical activity in a hot, humid environment puts you at a higher risk of heat illness. The risk increases if you wear heavy clothing or equipment. People who arent used to working in hot conditions have a higher chance of heat exhaustion.
  • Medications: Side effects of some prescription drugs include vomiting, diarrhea and dehydration, which can lead to heat exhaustion. Diuretics to treat heart failure reduce the amount of fluid in your body and can cause dehydration. Chemotherapy drugs and beta blockers can also increase the risk of heat illness.
  • Weight and general health: People who carry extra weight have a higher chance of heat exhaustion. Obesity and certain health conditions increase the risk.

What Are The Effects Of Heat On The Body

When the air temperature or humidity rises above the range for comfort, problems can arise. The first effects relate to how you feel. Exposure to more heat can cause health problems and may affect performance.

As the temperature or heat burden increases, people may feel:

  • Increased irritability.
  • Loss of concentration and ability to do mental tasks.
  • Loss of ability to do skilled tasks or heavy work.

In moderately hot environments, the body “goes to work” to get rid of excess heat so it can maintain its normal body temperature. The heart rate increases to pump more blood through outer body parts and skin so that excess heat is lost to the environment, and sweating occurs. These changes place additional demands on the body. Changes in blood flow and excessive sweating reduce a person’s ability to do physical and mental work. Manual work creates additional metabolic heat and adds to the body heat burden.

Do Dogs Bleed On Their Period

However, the most obvious recognizable sign of heat in dogs is vaginal bleeding. This may not become apparent until a few days after the female has come into estrus. Some female dogs experience heavy vaginal bleeding during estrus, while other dogs have minimal bleeding. If you are concerned, consult your veterinarian.

It’s Best To Take Your Chances

Now it should go without saying that you need to be smart about what you do. You don’t want to go run a marathon in 110°F weather with the sun beating down on you Or at least most people don’t want to do that because their bodies are nowhere close to being used to it.

But the heat, in most cases, isn’t something you should be avoiding like the plague. Be smart but don’t let it ruin your chances of getting outside and living a healthy enjoyable life.

When To See Your Doctor

It is quite normal to occasionally experience diarrhea after working out, but persistent diarrhea needs further evaluation. You can always change your diet and lifestyle to see if it resolves the issue, but see your doctor if the problem persists. Sometimes, there is a parasite or bacteria in your gut that needs to be eliminated. This is when you require medical assistance. Your diarrhea may also indicate a medical condition, such as ulcerative colitis, Crohnâs disease, microscopic colitis, celiac disease, or irritable bowel syndrome. Talk to your doctor and follow their advice to treat these problems.

Importance Of Gi Manifestations With Exercise

Severe heat exposure simulates hemorrhage and intestinal ischemia because blood pools in the cutaneous capacitance vessels, central blood volume and splanchnic blood flow decline, and mean arterial pressure falls because increased heart rate cannot fully compensate for a declining stroke volume that causes cardiac output to fall. Hemorrhage and intestinal ischemia increase capillary permeability and have been reported to produce mucosal lesions in the small intestine of humans , dogs , rats , and cats . The pathogenesis of the rise in capillary permeability has been attributed to the production of superoxide radicals , and the pathogenesis of the mucosal lesions has been attributed to hypoxia . Thus, it has been hypothesized that severe hyperthermia produces mucosal lesions in the small intestine from tissue hypoxia, increases capillary permeability, and results in endotoxemia . Systemic endotoxemia has been shown in human heat stroke victims , in ultramarathon runners who collapsed during competition in the heat , and following strenuous exercise .

Warning Signs: Thirst And Heavy Sweating

Extreme heat brings higher heat illness risk

“Heavy sweating is a sign that your body is producing a lot of heat,” said Bergeron, which could lead to heat exhaustion if conditions don’t improve or if they worsen. According to a research article published in 2020 in Medico Legal Journal, heat is more dangerous on humid days because sweat can’t evaporate off the skinwhich normally produces a cooling sensationas easily as it can with dry or breezy weather.

Feeling thirsty is also a sign that your body needs more water. Even if you don’t feel parched, it’s important to sip water frequently on hot days. If you’re out in the heat for more than an hour, a sports drink can also help replenish lost electrolytes.

Can Dogs Die From Heat

Dog Heat Stroke

Dogs do not sweat in the same way humans do and can easily become overheated, which can lead to heat stroke and severe medical complications, including death.

This virus can affect humans of all ages.

The virus can be found in the gastrointestinal tract and consequently in the feces or diarrhea of the infected dogs.

It can be transmitted from contaminated food or water to humans and the infection can rapidly spread in the human population by fecal oral rate.
