Q. With reference to Heat waves, consider the following statements:
1. An increase in humidity will worsen the impact of a heat wave.
2. India does not recognize heat wave as a disaster under the Disaster Management Act.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Both statements are correct.  

  • The presence of humidity in the environment prevents the thermoregulatory mechanism of evaporative cooling of the body through the process of perspiration, which can cause heat stress thus exacerbating the impact of a heat wave. 
  • The Indian government does not recognize heat waves as potential threat to human lives. The National Disaster Management Act and the National Policy on Disaster Management do not include heat wave fatalities in their list of natural calamities and so no budgetary allocation is made to address the problem.
