Thermal stress is among the most common physical hazards in various work sectors.
Indeed, the exposure to extreme temperatures can lead the worker to a state of heat stress, which occurs when the body is unable to maintain its temperature between 36 and 37 C . Heat syncope, heat exhaustion, heat stroke, dehydration, heat cramps, miliary eruptions, hyponatremia, and rhabdomyolysis are among the diseases or health disorders due to heat exposure. Hypothermia, immersion feet, and frostbite are the most significant injuries and illnesses caused by exposure to extreme cold.
Therefore, the prevention of thermal stress risks should be a priority in order to avoid any negative effects on workers’ health and safety. Adequate prevention of heat stress risks not only provides a sense of comfort for the worker toward his work environment, but it can also
have a positive impact on the productivity rate and result in a decrease in the employer’s number of injuries.
The materials used in the design of several types of PPE tend to avoid the adequate dissipation of body heat. It is essential to develop new tools and equipment to ensure thermal risk management adapted to the individual situation of the worker and his or her work environment. In such a context, graphene based smart textile technologies integrated into personal protective equipment have a very great potential to respond to many issues related to thermal risks.

The coating with graphene coating formulation it is applied on the outside layer of the textile and not inside as often reported by other
competitors. The reason, verified also by technical test, is due to the fact that in this way the high absorption rate of far infrared ray by
graphene allows to extract the heat from the body. If the coating with graphene would be applied inside there would be not real heat
extraction and dissipation because the coating would only keep the heat inside the body. We do not want to distribute the heat from the
body, we want to extract and reduce the sweat rate!
