A new study has found that men who are in their sixties are likely to die from a heart attack during warmer nights. University of Toronto scientists say that an increase in temperature by one degree Celsius can lead to a 4% increase in the number of deaths due to blood and heart diseases.

Heart disease is the leading death cause in the US

Heart illness is the leading cause of death in the United States, accounting for over 659,000 fatalities each year. Previous research has looked into whether hot spells in the summer are linked to an increase in deaths from blood and heart problems. However, when the gender and age of the participants were taken into account, the results were mixed.

Now scientists have discovered that an increase in temperatures can be the difference between life and death for those men in their 60s.

In a media release, the study authors stated, “The present findings should stimulate similar investigation of exposure and event rates in other populous mid-latitude to high-latitude regions. Furthermore, considering the growing likelihood of extreme summers in Western USA and UK, our results invite preventive population health initiatives and novel urban policies aimed at reducing future risk of CVD events.”

Temperature rise led to deaths in northern hemisphere countries  

Between 2001 and 2015, researchers looked at data on persons who died in the summer from cardiovascular disorders. The bulk of heatwaves in Wales, England, and other Northern Hemisphere nations, are expected to occur during summer. The team also gathered information from King County, Washington, which is located on the same latitude as Wales and England. The region likewise has comparable atmospheric characteristics, with only a small percentage of residents having access to air conditioning at home.

Over the period of study from 2001 through 2015, 39,912 deaths occurred due to heart disease in England and Wales, with 488 fatalities reported in King County. Increases in summer evening temperatures of 1 degree Celsius were linked to a 3.1% increase in deaths among men aged 60 to 64.
