Underarmour® and Nike® have flatly misled the world through their marketing campaigns about their products’ hydration through “wicking” and thermo-regulation benefits (the way the body stays cooled and core temperature stabilization). They represent that by “wicking the sweat away from your skin to the outside of your shirt you will gain a cooling effect and improve performance”. This could not be further from the truth.
In fact, the opposite is true. It is important to understand that when sweat appears on the body and then moves through fabric fibers to the outside of a shirt, the sweat vaporizes through the ambient air and body heat is released. (Even if the sweat is removed from the skin by wiping sweat from the body using your hand or a towel, evaporation cannot occur, and heat will be retained). Sweating will subsequently further increase, leading to an even greater loss of body fluid and further increased dehydration. Cooling is not accomplished by the evaporation of sweat. Exercise significantly increases fluid loss which can reach levels of up to 4 liters per hour during heavy work-outs.
A loss of body weight through dehydration of as little as 2% significantly impairs performance which emphasizes the importance of the maintaining hydration, especially during exercise”. (Armstrong et al 1985). Thus maintaining the sweat next to the skin actually provides the best mechanism to accomplish the “cooling effect” and only Dry Defense® technology provides for this to occur. Cooling is caused by air circulating within clothing (a shirt) and “impacting upon the body by cooling it down”. The more sweat against the skin and the more air, the better the "cooling effect".
Only Dry Defense® with it’s undetectable chemical technology provides for optimum performance through its improved heart efficiency, superior cooling and core temperature stabilization. Dry Defense® allows the fabric to pass through the air but will not allow the fluids to exit the point of “cooling effect”. No other product can make this claim.
The physiological internal effect of air cooling the body is the creation of oxygenated blood plasma (the nutrient rich proteins in the blood-which circulates within the body stabilizing the heart rate as well as the core temperature. The greater the “cooling affect” the better the performance for any athlete from 10% to 15%.
Additionally, blood plasma is 92% water, and therefore, dehydration reduces the volume of blood in the body which makes the cardio-respiratory system work harder to pump the blood around the body and deliver sufficient oxygen to the working muscles. Exercise feels much harder when your body’s systems aren’t working as efficiently as they do with good hydration.
As dehydration progresses, nausea and vomiting may be experienced. By a 5% reduction in total body weight, performance will drop by 30%. Fluid losses greater than this creates weakness, confusion and dizziness leading ultimately to coma and death if fluid isn’t replaced immediately.
The Patents and Science Behind Dry Defense®Technology
Hygienics Industries LLC. Is the parent company of Kleinert’s. It owns three mechanical and design patents covering the application and science around thermo-regulation and clothing. Effectively, the science of clothing keeping the wearer cooler thus providing better hydration and thus better performance.
Imagine Lebron James performing 10% to 15% faster or any other performance seeking athlete looking for the edge that will separate him from his competition.
Dry Defense® offers water-repellency, stain-repellency and odor/bacteria repellency. Dry Defense® is hypoallergenic and has been a commercial success for people worldwide for over ten years with no complaints. It will not wash out over 100 machine washings with proper care. The chemistry is protected by patents and only offered on an exclusive basis by Hygienics Industries LLC.
Only Hygienics Industries and Kleinert’s produces the Dry Defense® compression roll fabrics and also the sublimated roll polyester fabrics with Dry Defense®.
Physical exertion is very taxing to our bodies, and this effect is multiplied exponentially when under extreme environmental conditions. Performing in hot and cold environments places a heavy burden on the mechanisms that are designed to regulate body temperature. These mechanisms are incredibly effective in maintaining homeostasis in vivo; however, they can be severely taxed or strained when the external conditions change.
Body temperature is kept constant by balancing both heat gain and heat loss. Humans need to maintain a constant body temperature of about 37°C. To maintain this temperature at a constant point throughout the body’s internal systems, mechanisms must be in place to accurately measure present body temperature, and to regulate as needed. This system is known as the thermo-regulatory system. The metabolic heat generated by oxidation of food in the visceral organs and tissues (body core) is a constant source of heat. Core body temperature can also be dramatically increased with muscular activity, nervous and hormonal factors (such as sympathetic nervous activity), catecholamines, and thyroid hormones.
Body temperature can vary in different regions. The tissues of the extremities and the skin are far from the core (the core consists of the brain and visceral organs and tissues in the trunk), and they are in direct contact with the external environment. These tissues tend to have slightly lower temperatures.
For example: In a room temperature of 21°C, hand, foot and skin temperatures are about 28 °C and 21 °C respectively.
Even core temperature is not a constant 37°C at all times. A circadian (diurnal) cycle exists, core temperature being the lowest in morning (36.7 °C) and highest in the evening (37.2°C).
