Exercising in the Heat by Jason Karp, PhD on May 18, 2010 ideafit.com
‘..Hot and humid days present an even greater challenge. When it’s humid, the air is already saturated with water, limiting the amount of sweat evaporating from your skin. As a result, the ability to dissipate heat is minimized and core body temperature rises rapidly, leading to hyperthermia. In extreme cases, hyperthermia can lead to heat exhaustion and heat stroke.
Heat exhaustion, the most common heat illness, is defined as the inability to continue exercise in the heat (Armstrong 2000). Heat stroke is a medical emergency and occurs when body temperature rises to a level that causes damage to the body’s tissues (> 103–104 degrees Fahrenheit, or > 39–40 degrees Celsius) (Armstrong 2000).
In an attempt to prevent body temperature from rising to dangerous levels during exercise, your central nervous system orchestrates a complex response in which blood vessels supplying your inner organs constrict, while blood vessels supplying your skin dilate, causing blood to be diverted away from inner organs and directed outward to the skin to increase cooling through the convection of air over your skin’s surface. It may seem somewhat counterintuitive that as your core body temperature is rising during exercise in the heat, skin temperature decreases as a result of convective cooling. More blood being directed to the skin means less blood (and therefore less oxygen) going to the active muscles, causing exercise intensity to decrease and the perception of effort to increase. ..

11 Hydration Strategies for Hot Weather By Chrissy Wellington M.S., C.N.S., L.D.N., C.P.T
“.. Proper hydration is achieved during exercise by consuming fluids and electrolytes at regular intervals. During training distractions may prevent athletes from recognizing their thirst, occasionally fluids are not available precisely when thirst occurs, and by the time thirst is felt an athlete may already be dehydrated. Recommendations for hydration before, during and after exercise to ensure optimal sports performance are as follows: ..”

Considerations for Exercising in the Heat
Christopher Gagliardi // Program Design, Implementation and Modification // 9/9/2013 acefitness.org
So what do you need to know as a trainer? First, it’s important to have a good understanding of the heat index chart. You don’t need to memorize it, but you do need to understand the relationship between humidity and temperature (conditions become more dangerous as humidity and heat increase)…
Here are some tips to offer your clients before they begin exercising in the heat:
Begin exercise in the heat gradually as acclimatization typically takes seven to 10 days.
Always wear light-weight, well-ventilated clothing. Wear light-colored clothing if exercising in the sun as white reflects heat better than other colors.
Never wear non-breathable clothing.
Cotton is a good choice for exercising in the heat because it readily soaks up sweat and allows for evaporation.
Replace body fluids as they are lost. Recording daily body weight is an excellent way to prevent cumulative dehydration.
Air movement is critical for adequate cooling.
Heat Exhaustion webmd.com
“..Although heat exhaustion isn’t as serious as heat stroke, it isn’t something to be taken lightly. Without proper intervention, heat exhaustion can progress to heat stroke, which can damage the brain and other vital organs, and even cause death.

Treatment for Heat Exhaustion
‘… Remove any tight or unnecessary clothing.

Treating Heat Stroke
In heat stroke, every minute counts. When core temperature is very high, body and brain cells begin to die, so fast cooling is vital. Early features are subtle central nervous system (CNS) changes — altered cognition or behavior — and core temperature over 104-105 °F (40.0-40.6 °C). When an athlete collapses, the best gauge of core temperature is rectal temperature; oral, axillary, or ear-canal temperature will not do. Advanced features are collapse with wet skin, core temperature over 106-107 °F (41.1- 41.7 °C) and striking CNS changes — delirium, stupor, seizures, or coma (Roberts, 1998).
Field treatment is fast cooling. No faster way to cool exists than dumping the athlete into an ice-water tub. Submerge the trunk — shoulders to hip joints. Research suggests ice-water immersion cools runners twice as fast as air exposure while wrapped in wet towels (Armstrong et al., 1996). The Marines also use ice-water cooling (Kark et al., 1996). Recent field research with volunteer runners suggests cold water may cool as fast as ice water (Clements et al., 2002)…’

Know the Foods That Hydrate Your Body
“…When fasting, we’re slowly being dehydrated over the course of the day, so once we break our fast and during the non-fasting period we need to have foods that put water into our body, not deplete it further. It can be difficult to eat a lot of watermelon or squash, even though they’re super-hydrating foods, but you can make juices out of the fruits and soups out of the vegetables to give your body the additional water it needs. Avoid salty spice mixes and condiments that sneak their way into our rice and meat dishes only to leave us wondering why we’re so thirsty afterwards. A great way to break the fast is to enjoy your favorite dates, of course, but also consider having coconut water, or making smoothies, coolers and fruity drinks which are super-hydrating. They can be consumed at the Suhoor (pre-dawn meal before the fasting day begins) or at the Iftar (meal at the time of breaking the fast) followed by soup to preface your main meal. Consider limiting coffee and tea which are very dehydrating to the body, to about half of what you normally drink…”
