A recent study has shown that people over the age of 60 are the most vulnerable to heat waves, with 82% to 92% more deaths than average occurring in this age group.
Based on the research, risks for heat-related illness or injury such as heat stroke, heat exhaustion and heat cramps are also
heightened in people with obesity, heart disease, diabetes and respiratory conditions as these decrease the body’s ability to adapt to temperature changes.
The researchers said physicians and their patients must be aware of the risk factors for older people and people with chronic disease in excessive heat conditions and counsel and manage accordingly.
According to the researchers, laboratory-based physiologic studies show that the ability to detect heat is reduced, and the physiological response to heat with adequate blood distribution and sweating to cool the body is slower, in otherwise healthy older individuals compared to younger people.
The research team explained their ability to respond to thirst is also delayed and they take longer to recover from dehydration.
Moreover, the study has also shown that people of lower socio-economic groups, lower levels of education and those who are socially isolated have a greater risk of mortality.

The elderly need to be careful since they are at higher risk from suffering from heat stress.

The researchers said air conditioning is associated with a risk reduction of 80% and working fans with a 30% reduction.
The researchers added housing may be a factor as lower income people often live in crowded or poor-quality housing, with inadequate ventilation and cooling systems.
They revealed homeless people are at risk because of lack of shelter from extreme heat and often also by underlying physical or psychiatric issues.
Dr. Glen Kenny from the Faculty of Health Sciences at the University of Ottawa and his co-authors said the new research should focus not only on filling these gaps in the science-based information but also on developing clinical guidelines for health professionals to facilitate the giving of advice to patients.
