As extreme temperatures are likely to continuously increase as climate change strengthens its grip on the world, studies like this are important as we seek to mitigate the effects of such volatile weather patterns. Since this is a global issue, medical professionals around the world need to account for these environmental factors when dealing with their patients. Climate change and public health are deeply linked.
While this study may prompt discussions around climate change, more research is needed. One cannot simply lay heart disease deaths at the feet of heat waves and cold snaps when so many other factors in the developed world — such as lifestyle choices like diet which lead to obesity and diabetes — also play a significant role. The climate isn't the common denominator of everything.
