HOT DOT BODY TEMPERATURE ALERT PATCH
Every football coach tries to push his players to their limits, but no coach wants to push a player too far. The Hot Dot Body Temperature Alert Patch serves as a visible heat alert that each player can wear to make it easier to detect heat-related illnesses.
ACCORDING TO A November 2014 report in USA Today, there are more deaths in football due to heat-related illness each year than those related to concussions and spinal-cord injuries combined. Every year, at least 10 children die each year from heat stroke during a game or practice, according to the National Center for Catastrophic Sport Injury Reach. In addition, more than 9,000 high school athletes are sickened by heat-related illness annually.
The innovators at Hot Dot Inc. set out to prevent heat-related illness on the football field by creating a patch that allows coaches, teammates and trainers to monitor a player’s core temperature before it’s too late.
The Hot Dot Body Temperature Alert Patch uses heat-sensitive technology to provide an early warning for potentially harmful heat illness in real time. Thermochromic crystals reflect the rise and fall of the body temperature by changing the patch color from black to yellow as a player’s body temperatures shifts to unsafe levels. This warning sign will cue coaches and trainers to remove a player in danger from the field of play. After removal the player can be assessed for potential heat illnesses. One benefit of the patch is that it will return to its black color when temperatures return to lower, safer levels. “Heat-related illness is not something people are talking about, and the awareness needs to be raised,” said Travis Meyer, CEO of Hot Dot Inc. “We did as much research as we could to create a patch to help prevent heat stroke and heat- related illness.”
The quarter-sized patch, which has been submitted to the Korey Stringer Institute for testing, should be worn on areas of the body where blood vessels are nearest the surface and the skin is exposed, such as the forehead, wrist, neck or forearm. This spring, Hot Dot Inc. is preparing to release a patch that can serve the dual-purpose of eye black. The hypoallergenic adhesive is water resistant in order to sustain heavy sweat.
Studies have found that heat stroke starts to occur at 104 degrees Fahrenheit. The innovators at Hot Dot Alert set the alert temperature at 102.5 degrees while factoring in one degree as the margin of error.
“With the soon to be released eye black patch, it will be visible to coaches without taking the helmet off,” Meyer said. “It takes away the option of self-diagnosis, but it gives the trainers and coaches the ability to assess.”
THE HOT DOT BODY TEMPERATURE ALERT PATCH ALLOWS YOU TO MONITOR YOUR BODY TEMPERATURE CHANGE IN REAL-TIME DURING PHYSICAL ACTIVITY.
The Hot Dot Alert Patch has been tested at the Korey Stringer Institute at the University of Connecticut. Douglas J. Casa, PhD, served as the principal investigator. Through his research, he found that when compared against the rectal temperature, the wrist had the closest activation temperature with the predetermined set point by Hot Dot Alert. The forehead patch had the least number of issues with adhesion and color readings.
Most importantly, the Hot Dot Body Temperature Alert Patch can notify people of the onset of hyperthermia in an exercising individual.
“Hyperthermia happens very quickly,” Meyer said. “Our product can assess temperature changes within seconds. The onset of heat stroke may occur at internal temperatures of 104 degrees or above, but the product is changing before that. There’s ample time to remove the player from the action and assess the individual to return to action when safe.”
Casa’s primary suggestion after testing was to improve the shape and location of the Hot Dot Alert Patch on a football player’s body to improve adhesion. Hot Dot Inc. has taken those steps and is excited about the development of the eye-black version.
