At the Atlanta Science Festival, me and my team members, Ashmita and Claudia, had the pleasure of getting to talk about Heat Stroke to a large audience of individuals and explain the seriousness of it, and why it’s so important to pay so much attention to it and take so much initiative to prevent it. Not only did I enjoy this experience because it gave me experience speaking in public in front of a large group of family members! But, in doing so, I myself actually became more interested in the topic and its political, social, and economic implications. Being a Biomedical Engineer, this topic also hit close to me as it reminded me of a pressing global problem, where the solutions still have significant limitations in their capabilities and how accessible they are all around the world, an issue that I commonly learn how to tackle throughout my degree. In this post, I hope to do two things. I hope to share the information and insight I learned about heat stroke with those who were unable to come to the Atlanta Science Festival. Second of all, I hope I can share with you some of the ways I have thought about solving this pressing problem of Heat Stroke and my thought process to go about solving it!
First of all, many of you are probably wondering, haven’t we all dealt with Heat Stroke? After all, Atlanta is perpetually hot all the time! Heck, it’s just the beginning of May and it already feels like it’s 140 degrees. However, as miserable as that might have been, I promise you that that was not Heat Stroke! What you likely dealt with was Heat Exhaustion, which is extremely uncomfortable, but I promise you that it is not nearly as bad as Heat Stroke! With Heat Exhaustion, at least your homeostatic mechanisms are still working. You know your Homeostatic Mechanisms, the ones that ensure that your body is still in balance, even with changes in the environment to prevent you from developing diseases or dying?! Do you remember how, for instance, when you have gone and exercised quite a bit or you have been outside in the hot sun for some time, you have sweat quite a bit? These are examples of your homeostatic mechanisms kicking in, so you do not have a detrimental response to these environmental changes. The problem, though, is that like everything in life, these mechanisms designed to protect you can fail. Eventually, the hypothalamus, which is responsible for maintaining this homeostasis gets worn out. When that happens, you are basically exposed to this significantly increasing temperature, without any defense mechanism to fight back (Garcia 6). At that point, you are essentially overheating like a computer which is something that can lead to significant consequences, including death, which I will discuss as we go forward!
So now that you know the difference, the next thing that you are probably doing is, what can we do to better deal with the increasing incidence of Heat Stroke in our society? First of all, healthcare providers in our society have to do a better job of treating Heat Stroke with the same level of urgency as other critical illnesses and have to treat it more like diseases, such as Appendicitis, where you will immediately die if you do not get the necessary surgery. This is extremely similar to that. In the case of Heat stroke, not getting treatment immediately can lead to muscle, kidney, heart and even brain damage. The other side of this argument is that more effort has to be taken by the individual to prevent the detrimental consequences of heat stroke and take early action before it is too late, and there are significant, everlasting effects. Simple steps may seem inconvenient, but they can ensure prevention of the worst outcomes from heat stroke. For instance, steps, such as drinking enough fluids, looking out for health related problems with medications, applying sunscreen, and avoidinging overworking in the heat can go a long way. Additionally, significantly more funding has to be spent by the government in investing in the protective equipment necessary to effectively prevent heat stroke as investing money in vaccines, and treatments for other diseases. While two solutions, besides just protective equipment, Neck Fan and the Ice Pack, have gone a long way in attempting to prevent and mitigate Heat stroke by helping to constantly blow cold air around a person’s neck, so as to help that person cool off and bring their body temperature down and reducing body temperature by promoting the contraction of blood vessels; thereby, ensuring that joints are less stiff and that muscle spasms are less likely to occur, these solutions have limitations in the long-term. Eventually, an issue will arise with long-term use of these interventions and something more will need to be done to prevent a significant rise in temperature in just a short period of time. This is especially true for individuals who are in jobs that exposes them to significant amounts of heat on a chronic basis (Kim 4). Additionally, while current PPE are effective in preventing certain infections, they also add to the problem of heat exhaustion and heat stroke (Steps to Put on Personal Protective Equipment (PPE).” World Health Organization, World Health Organization).
This is where research from Georgia Tech and other universities in this area has come to extremely significant use in helping to create longer-lasting and more effective solutions. The solution from Georgia Tech researchers resulted from a way of thinking that was completely outside the box of the problem, but got to the heart of what was necessary! Tech researchers have found that with the creation of a sensor system, through the utilization of a cloud based sensor system, not only can heat stroke be treated effectively, but its incidence can be significantly reduced to begin with (GTRI Helps Develop Wearable Sensor System to Prevent Heat Injuries among Soldiers). Trust me, this technology is way too much for me to understand! However, the gist is that researchers will be able to obtain information about changes in soldiers’ temperatures over significantly large distances. Too large of a heat increase in too short a time will still be a problem. Make no mistake! However, the hope is that if a rapid heat increase is detected before it becomes an extreme issue, a soldier can get the help that they need to prevent complications (Foy 2). This is especially true with the use of local networks, which should be able to tell a soldier whether there are any soldiers in close proximity to them that can assist them. In the long-term, I hope that I can build upon this work to create an internal cooling mechanism to bring down the temperature and a method to help predict baseline normal temperature, based on the thickness of the suit and the environment an individual is working in. For now, though, I hope I have at least been able to better provide insight into why Heat Stroke is such a big problem and why it is one that both more individual and societal effort is needed to solve!
