Heat in Fall Football, and the Infallible, Young Athlete 0
Every year young athletes die from heat stroke. In 2015, high school fall football practice alone resulted in two (2) heat stroke deaths in Indianapolis, Indiana and Brownsville, Tennessee. There are no statistics for those who experienced heat stroke and lived, and no statistics for those who were close to heat stroke before cooling down. With a heat wave sweeping the nation, this season’s fall football practices could be much worse for heat illnesses, including heat stroke.
Heat illness problems with young athletes, especially in fall football practice, are multifaceted, but they can be broken down into the following areas: 1) Young athletes are not conditioned to the heat due to spending much time in air-conditioned spaces over the summer. 2) Many athletes lose physical conditioning over the summer as well, which may or may not include a weight gain, which adds to exertional heat stress (EHS). 3) Some young players coming out for football for the first time have never been through any physical conditioning before their first football practice 4) Fall football practices occur during one of the hottest months of the summer. In the south, especially, that can also mean periods of higher humidity, which increases heat stress. 5) Dehydration from sweating adds to heat stress on the body. It is especially important for the young athlete to stay hydrated throughout exercise and not to wait until a feeling of being thirsty is evident before taking a hydration break. 6) Last, but of greater importance in young athletes, as opposed to older, professional athletes, is the feeling of being infallible.
Medical science has proven that the ability to reason in the human brain does not fully develop until the early twenties. For the young athlete wanting to prove himself to his teammates and coaches, this means he may wait until he is in serious physical trouble before notifying anyone of his physical problems.Young athletes often dismiss the heat illness symptoms they are experiencing because they believe they are physically strong enough to keep going without any significant consequences. It is this feeling of infallibility that can get a young athlete into trouble before anyone else recognizes there is a problem.
In the heat stroke death cases of many young football players, the athlete simply collapsed before anyone became aware that there was a problem. The symptoms of heat stress, followed by heat exhaustion, were most certainly evident to the young athlete, but not acted upon. The athlete’s body was screaming that he was in trouble, but he pushed on until his body could no longer handle the heat and a heat stroke occurred.
Individual athlete physical evaluation is one of the major reasons it is so important for coaches to have training in recognizing the signs and symptoms of heat stress, heat exhaustion, and heat stroke. Coaches monitor the development of skills and the physical conditioning of each athlete so they should be aware of physical and mental changes in each athlete.
Even when athletic trainers are present, the responsibility falls on the coaches. Individual evaluation is also why it is important to teach every athlete to recognize heat illness symptoms. Each athlete is in a position to recognize changes in teammates as well as in himself. Teammates look after each other. When it comes to young athletes who feel infallible, having a teammate intervene when serious heat illness is recognized, allows an outside observer to override the infallibility complex.
When the athlete himself ignores the serious messages from his body, and keeps it hidden from his coaches, his teammates become the last line of defense in the prevention of heat stroke. They are training next to each other, interacting with each other, and, if they know what to look for, they should notice serious physical and mental changes in each other. If the athlete in heat trouble does not remove himself from training to cool down, any teammate should be able to notify a coach or trainer that he suspects a serious heat illness problem.
Uninterrupted physical exertion in hot, humid weather can quickly escalate heat stress to heat stroke. The human body will continue to heat up after activity is stopped because it is working hard to rid itself of heat. The only way to stop the increasing heat is to immediately start the body cooling down through any means possible.
Hydration should occur throughout the exercise, but if the athlete is in serious heat trouble, he may not be able to drink. The body needs water and electrolytes to replace what it has used in sweat trying to cool itself down and to continue in the cooling process, so as soon as the athlete can drink, hydration should begin. Waiting for professional medical help is NOT an option. The prevention and treatment of heat stroke are the same, “Don’t wait! COOL DOWN and HYDRATE!”

Understanding Heat in Work Environments 0
Understanding Heat in Work Environments
There are three types of hot work environments: 1) weather dependent - outdoor or indoor environments affected by the weather, 2) non-weather dependent - those environments due to the nature or place of the work to be performed, and 3) a combination of both - when the non-weather dependent environment becomes part of the weather dependent environment.
The hot work environment is only one contributing factor leading to heat illnesses in healthy workers. The degree of physical effort and dehydration are also two major contributing factors to heat related illnesses.
Weather Dependent Hot Work Environments
Heat, humidity, and direct sunlight contact are three factors presented by Mother Nature that are beyond human control. It is not enough to understand the significance of hot temperatures on the worker, one must also consider the humidity and the increase in overall temperatures when work is done in direct sunlight. The human body can withstand higher temperatures when humidity is low because body sweat evaporates quickly to cool the body. As humidity goes up, the air becomes less absorbent, and the ability of the body to cool itself through sweat evaporation, decreases. Any person working in hot weather when humidity is high is at a higher risk for developing a heat illness than when humidity is low.
Link to the National Weather Service Heat Index Calculator and find the heat index for the specific temperature and humidity for any weather related work environment at any time: http://www.wpc.ncep.noaa.gov/html/heatindex.shtml
The temperatures in the heat index chart above are “air” temperatures, which are taken in the “shade“. Direct sunlight contact will raise the temperature index by as much as 15F. Just as direct sunlight contact with innate surfaces raises those surface temperatures, it raises the temperature of the human body. For example, the surface of a black car in direct sunlight will be hotter than the surface of a white car in direct sunlight, and both will be hotter than the temperature of the air. Just as surface heat is transferred to the inside of each car, the heat of direct sunlight on the surface of the human body is transferred through the skin to warm the body’s core. Also, as with the white car, the heat effect can be lessened with the use of light colored, lightweight clothing.
Non-weather Dependent Hot Work Environments
Non-weather dependent hot work environments are created by the heat generated and/or contained within the environment, or due to the task being performed, or both. These include places where heat-generating equipment is used, such as bakeries, foundries, etc., or wearing heavy, protective clothing that holds in heat, such as that worn by welders, hazmat crews, fire-fighters, and others.
Hot work environments that are created by the nature of the job itself require frequent monitoring of the worker. Take for example, a worker making repairs on a very large, hot, metal tank. The radiant heat from the tank itself may literally pull moisture away from the worker’s body. Because the worker’s clothes do not show significant signs of sweating, to others, the worker may not appear to be hot, when in fact, his body temperature may have risen to a dangerous level. Dehydration in this type of situation can also rapidly occur.
Combination Hot Work Environments
When the work to be performed creates a hot work environment, and this work is done in a hot weather environment, the chances of a worker developing a serious heat illness become greater. Take for example, hazmat crews working an outdoor chemical spill in full protective gear. Even with cooling vests worn under their suits, workers generally work on a 30-minute rotation, 30 minutes of work followed by 30 minutes of hydration and rest in a cool environment, usually an air-conditioned trailer or vehicle. This cooling time allows for full heat recovery before the next rotation begins. The hazmat suits create a closed, non-weather related work environment that heats up due to body heat and which is exacerbated by weather related heat. If the weather is very hot, shortened work periods may be required.
Exertional Heat Stress
The term “work environment” implies physical exertion. Physical exertion is required to perform any task. It is the degree to which it is required in performing the task that becomes a factor in heat illnesses. A desk clerk, even in a hot work environment, is not likely to be at risk of a serious heat illness. A laborer performing physical tasks in that same hot work environment would be at risk according to the degree of
his physical exertion. It is this physical exertion that introduces another factor in heat illnesses known as Exertional Heat Stress or EHS.
Even on a day when environmental temperatures are pleasant and humidity is low, a worker can become overheated from strenuous, physical work. Just as in athletes, the duration of the physical effort also affects body heat. The greater the physical effort and the greater the duration of the physical effort, the greater the body heat generated. Add EHS to any type of hot work environment and additional monitoring for heat illnesses is required, especially if the work is in direct sunlight or humidity is also high.
Dehydration is the loss of water from the body, which occurs mainly through urination and sweat. It almost always accompanies heat illnesses.
The human body is around 70% water, with the brain being made up of 73% water. As dehydration progresses, the brain loses the water it needs to function at its best. As body heat rises, the body produces sweat for evaporation to cool itself. Too much sweating causes dehydration, which in turn lessens brain function, decreases the body’s ability to cool itself, lessens toxins removal, causes low levels of sodium, potassium, chloride and other needed minerals, and deleteriously effects other body functions.
Staying hydrated only requires the worker to regularly drink cool fluids, preferably water and electrolyte replacing drinks. Hydration isn’t only easy, it is essential on all levels for keeping workers safe and efficient in their tasks.
Stopping Heat Stroke
A hot environment, physical exertion, and dehydration can lead to heat illnesses that require immediate attention. Heat stroke is 100% preventable. Every employer and employee subject to a hot work environment should know the signs and symptoms of heat illnesses and know how to prevent and treat them.
It is important to understand that heat stroke occurs when body temperature reaches 104F. Because the body can no longer adequately cool itself, the body temperature will very likely continue to rise, and without immediate intervention, death can occur shortly afterward. When heat stroke occurs, the first 10 minutes are critical for preventing brain and other organ damage, and death. Lowering the body temperature becomes essential for survival. The quicker the body temperature is lowered, the less likely damage to the brain and other body organs will occur.
While hydration is also needed, if the person is in heat stroke, he or she may not be able to drink. Once the body temperature is down and the person can drink, start giving cold fluids.
To get the person’s temperature down quickly, move the person away from the heat source. If in the sun, shade the person and immediately apply cold therapy. Cold therapy is any method of lowering body temperature by applying continuous cold to the body in any safe form - ice, ice water, cold water, cool water, cold blankets, cold packs, and vigorous fanning. In short, by whatever cooling application is available. Moving the person away from the heat source, shading, and waiting for emergency medical services to arrive is NOT an option to prevent or treat heat stroke. Cooling the person down is the only option to prevent and treat heat stroke.
Whenever heat stress has escalated to heat exhaustion, medical services should be called, and on-site cooling of the person should immediately begin. Heat Stroke can occur suddenly, without any symptoms of heat exhaustion. As previously stated, heat stroke is 100% preventable. When a heat illness occurs on the work site, the single over-riding rule is “COOL DOWN and HYDRATE”. Don't wait for medical services to begin cold therapy. Doing so could result in death. If every employer and employee learned and executed “COOL DOWN and HYDRATE” by any means possible while waiting on medical services, heat stroke in the work place could be eliminated.

Heat And The Private Investigator! 0
Anyone who has a car knows how hot it can get when left parked in the sun. All of us look for the shady spots whenever possible, but if you’re a private investigator, you choose the best spot for surveillance, in the shade or not.
PIs should use light colored vehicles with light interiors because dark vehicles get hotter than light vehicles….well, maybe not. It takes a little longer for cars with lighter interiors to heat up than it does for those with dark interiors, but they all heat up. Glass windows insulate the vehicle and hold heat inside the vehicle where the temperature can jump to above 120F in less than 10 minutes on a sunny, hot day anywhere, and can approach 200F in 30 minutes in the arid U.S. southwest. Now imagine you have to be in a vehicle for hours without anyone knowing you are there.
What are the options for PIs?
- Tinted windows
- Reflective windshield shades
- Side window shades
- Park in the shade whenever possible
- Insulate the vehicle interior as much as possible.
- Portable 12V fans
- Wicking clothing
- Seat cushions which allow air flow
- An ice chest of cold water, frozen gel pads, and wet towels
- A thermometer visible at all times
One amazing option for PIs is a 12V Go Cool, the only patented, portable, ice-water, air conditioner on the market! Go Cool dehumidifies, does not produce heat, does not need exhausting, and only pulls 1.6 amps! One private investigator liked it so much he permanently installed it into his vehicle.
The Best Portable Air Conditioner For Camping 0
Today we're discussing how our portable air conditioner makes your camping experience much more comfortable! While family camping tents offer a lot of screen mesh in doorways, windows, low vents and ceilings to take advantage of breezes and convection, family campers sometimes need assistance with the conditions inside the tent body. Campers who live in very warm, humid climates, such as the southeastern U.S. states, may realize that neither ventilation nor a fan will be enough to make the tent comfortable. The humidity in the air may be worse than the air temperature itself.
Fortunately, the GoCool portable air conditioner can make a family tent quite comfortable, even on a very warm, humid day. It is the only device that can transfer both heat and humidity out of the tent body! A GoCool portable, battery powered air conditioner is perfect for camping. "If you start the fire, I'll start the breeze" can be the next thing said at your family camping adventure and you'll never look back.
With summer underway, it’s not just time to think about vacations and baseball. The arrival of the summer days means the arrival of summer heat, and that’s not a topic you should regard lightly. It’s not just a matter of your comfort. It’s also about your health. Don't sweat the heat this summer, cool off with GoCool!
Great Situations For Portable Air Conditioners 0GoCool's portable air conditioner is the original portable, battery operated air conditioner. Portable air conditioners are great options when other cooling methods aren't available or insufficient. So who needs portable air conditioners? Here are some examples of people who need them:
- Apartment tenants: These are perhaps the largest group of people who buy portable air conditioners. In most cases, the landlords have not made it easy for them to install a permanent air conditioner. Maybe the landlords simply didn’t allow the installation of permanent air conditioners. Or there is one already, but its cooling capacity is insufficient.
- Home owners: Some homeowners also don’t want the bother of installing air conditioning. Maybe they're already planning to buy a new home and installing one isn’t worth the expense or perhaps some rooms are not used often so it’s not worth it to install air conditioning for them.
- Office workers: Many offices use air conditioning ever since it became common knowledge that the temperature is perhaps the most important factor that affects worker productivity. When it’s too hot, people can’t concentrate and creativity decreases. More mistakes are made, and tempers can flare. Even computers need cooler temperatures so that they don’t overheat.
- Camping: Camping is great, and usually you don’t need air conditioning when you go camping overnight. Most of the time, it is cooler in the outdoors at night. Sometimes the tent comes with lots of screen mesh to take advantage of the evening breeze. Others use fans or evaporative coolers to keep comfortable. Sadly, all these solutions don’t really work all the time, especially if you’re in an area where it’s both hot and humid.
