The other condition involved a hot, humid day with a heat index of 133 degrees Fahrenheit, similar to a July 1995
heat wave in Chicago.
'However, the good news is that
heat waves are also predictable and preventable.
Table-2 demonstrates the comparison of laboratory values and treatment offered among survivors and non-survivors of
heat wave period.
Since the turn of the century, it is thought that
heat waves have been responsible for tens of thousands of deaths, including regions of Europe and Russia, said study co-author, Antonio Gasparrini, associate professor at London School of Hygiene and Tropical Medicine.
We need to control air pollution, improve energy efficiency, optimize the urban landscape, green our rooftops with small plants, use highly reflective construction materials, expand urban plantation, increase public awareness about how to avoid and survive
heat waves, establish urban cooling centres and have the ability to predict imminent heat-waves.
On the other side, if people cannot adapt to future climate temperatures, deaths caused by severe
heat waves will increase dramatically in tropical and subtropical regions, followed closely by Australia, Europe, and the United States, according to a new study led by Monash University, Australia.
Among non-AC residents relative to AC residents at baseline, difference-in-differences modeling estimates showed an increase in reaction time (STROOP, 13.4 percent; ADD, 13.3 percent) and a reduction in throughput (STROOP, −9.9 percent; ADD, −6.3 percent) during
heat waves. ADD showed a linear correlation with indoor temperatures, while a U-shaped curve described STROOP, with linear effects below and above an optimum range (indoor temperature 22 to 23 degrees Celsius), with increased reaction time of 16 and 24 ms/degree Celsius, respectively.
The
heat wave has hit eastern Canada since early July, but only Quebec has recorded a rise in deaths linked to the scorching temperatures.
Climate data were obtained from meteorological department, Karachi and it coveredthe17th - 24thJune during 2015 because the
heat wave appeared during this time span.
The Pakistan Meteorological Department (PMD) issued a
heat wave alert for Karachi on Sunday, saying that 'another
heat wave of moderate/severe intensity will engulf Karachi and suburbs from Tuesday to Thursday.'
Estimates of
heat wave effects varied widely from city to city.
