Risk of heat-related health problems increases with age
Summer often brings excessive heat, which can lead to heat-related problems caused by hyperthermia, an abnormally high body temperature. Older adults and people with chronic medical conditions are particularly susceptible to hyperthermia and are at high risk for heat-related death. The National Institute on Aging (NIA), part of the National Institutes of Health, has some tips to help older people avoid the hazards of hot weather.
Hyperthermia is caused by a failure of the heat-regulating mechanisms of the body to deal with the heat coming from the environment. Heat fatigue, heat syncope (sudden dizziness after prolonged exposure to the heat), heat cramps, heat exhaustion and heat stroke are forms of hyperthermia. These conditions can pose special health risks for older adults, and can increase with the combination of outside temperature, general health and individual lifestyle.
Factors that may increase hyperthermia risk include:
Lifestyle factors increasing risk for hyperthermia in hot weather can include not drinking enough fluids, living in housing without air conditioning, lack of mobility and access to transportation, overdressing, visiting overcrowded places and not understanding how to respond to the weather condition. Older people, particularly those with chronic medical conditions, should stay indoors on hot and humid days, especially when an air pollution alert is in effect. People without air conditioners should go to places that do have air conditioning, such as senior centers, shopping malls, movie theaters and libraries. Cooling centers, which may be set up by local public health agencies, religious groups and social service organizations in many communities, are another option.
If you suspect that someone is suffering from a heat-related illness:
Heat stroke is a life-threatening form of hyperthermia. It occurs when the body is overwhelmed by heat and unable to control its temperature. Heat stroke occurs when someone’s body temperature increases significantly (generally above 104 degrees Fahrenheit) and has symptoms such as mental status changes (like confusion or combativeness), strong rapid pulse, lack of sweating, dry flushed skin, faintness, staggering or coma. Seek immediate emergency medical attention for a person with any of these symptoms, especially an older adult.
The Low Income Home Energy Assistance Program (LIHEAP) within the Administration for Children and Families in the U.S. Department of Health and Human Services helps eligible households pay for home cooling and heating costs. People interested in applying for assistance should contact their local or state LIHEAP agency or go to: http://www.acf.hhs.gov/

The NIA leads the federal effort supporting and conducting research on aging and the medical, social and behavioral issues of older people. The Institute’s broad scientific program seeks to understand the nature of aging and to extend the healthy, active years of life. For more information on research and aging, go to www.nia.nih.gov.
About the National Institutes of Health (NIH): NIH, the nation's medical research agency, includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. NIH is the primary federal agency conducting and supporting basic, clinical and translational medical research, and is investigating the causes, treatments and cures for both common and rare diseases.
