Sideline Cooling for Heat Stress, Performance & Recovery
WElkins' Sideline Cooling System is a portable personal cooling device designed to combat heat stress, improve performance, enhance safety and accelerate recovery for athletes of all ages and sports—from running to football to endurance cycling. The System's non-invasive surface microenvironment cooling technology is easy to use, deploys in seconds, and delivers highly efficient cooling to the wearer’s head and neck. Intuitive controls simplify operation, while rugged design and internal power provide superior durability, reliability and portability for easy use on the sideline, in the locker room and even at home.
Cold therapy is effective for combating heat stress and improving performance by optimizing %V02 max, lowering heart and sweat rates, and increasing blood flow to the muscles. In addition, selective head cooling may help manage the pain and inflammation associated with mild traumatic brain injury (mTBI, or concussion), which could improve player safety and accelerate recovery.
WElkins Sideline Cooling System combines patented, NASA-spinoff technology with battlefield-proven design:
COOLING FOR PERFORMANCE
Despite accounting for ~10% of body surface area, the head does double duty as major heat exchanger & thermostat for the body.
Precooling is a popular strategy to combat heat stress and improve endurance, with studies demonstrating its efficacy in lowering pre-exercise core temperature, increasing heat storage capacity, and improving exercise performance in humid and hot conditions. Indeed, even in moderate temperature, cooling can have a significant impact: in one study, subjects were asked to cycle as hard as possible for 1 hour at 65°F with and without pre-cooling. With pre-cooling, cyclists increased their work rate by 7% and extended time to exhaustion by 12%, while reducing both sweat and heart rates.
Cooling can also be effective during exercise, to reduce heart and sweat rates, decrease %V02 max consumed for evaporative cooling, and increase the supply of oxygen-rich blood to the muscles. Active cooling can be effective even in short intervals, making it well-suited for repetitive, routine cooling implemented throughout exercise, i.e. between periods, innings, quarters, or heats. If severe heat stress occurs during exercise, external cooling is a fast and effective intervention: "If you cool someone right away, on site, they don't die—period." (Dr. Casa, UConn)
COOLING FOR HEAD INJURY / CONCUSSION
Athletes ice every other part of their body after an injury, so why not cool the brain?
There is no universally accepted, proven effective treatment for mTBI/concussion in modern science, despite the scale and scope of the issue (1.6-3.8 million sports-related concussions in the US each year). Emerging science suggests that, in cases of concussive or sub-concussive injury, selective brain cooling may help prevent tissue damage by reducing intracranial pressure and maintaining cell membrane integrity. Moreover, cooling may help proactively address the known destructive synergism between brain hyperthermia and mTBI by delaying or reducing brain hyperthermia elevation during physical activity.

Given its long track record (dating back to Hippocrates of Ancient Greece) of safe use in both clinical and non-clinical settings, cold therapy holds great promise for prevention, intervention and management of head injury on and off the field of play. Mild brain cooling won't hurt, and it may very well help injured athletes. That said, be aware that cooling alone is no substitute for proper medical advice and treatment; WElkins urges you to seek immediate medical attention from a clinician if you suspect experience or suspect head trauma.
WElkins Sideline Cooling System Overview
The Sideline Cooling System is a portable personal cooling device designed to combat heat stress, improve performance and accelerate recovery for athletes of all ages and sports–from contact football to endurance cycling. The system consists of a lightweight, flexible Cooling Cap through which ice-chilled coolant is circulated from a Mobile Cooling Unit:
