The United States is experiencing record-breaking heat waves that are putting millions of people at risk, particularly those with chronic health conditions. Extreme heat is a growing concern, especially in the South and Southeast regions of the country, where conditions such as heart disease, diabetes, and kidney disease are prevalent. This blog will explore how extreme heat exacerbates these chronic health conditions, the regions most affected, and the role of healthcare systems in managing the impact.
The Impact of Extreme Heat on Chronic Health Conditions
As temperatures rise, the human body’s natural cooling mechanisms can become overwhelmed, particularly in individuals with underlying health conditions. Extreme heat, defined as prolonged periods of high temperatures, can worsen the symptoms and complications of chronic diseases. For millions of Americans, this creates a life-threatening situation.
Effects on Heart Disease
Heart disease is one of the most common chronic health conditions affected by extreme heat. The body attempts to cool itself by dilating blood vessels, which increases the workload on the heart. For people with heart failure, the heart is already struggling to pump enough oxygen-rich blood throughout the body. The added strain from high temperatures can lead to dangerous consequences, including heart attacks and exacerbation of heart failure symptoms.
According to the Centers for Disease Control and Prevention (CDC), older adults on Medicare living in Southern and Eastern states have the highest rates of hospitalization for heart failure during heatwaves. Dr. John Sherner, chair of medicine at MedStar Washington Hospital Center, emphasizes that people with chronic heart conditions are especially vulnerable to extreme heat due to their bodies’ inability to regulate temperature effectively.
Effects on Diabetes
Diabetes, particularly type 2, is another chronic condition that is aggravated by extreme heat. People with diabetes often have impaired circulation, which hinders their bodies’ ability to cool down. Additionally, certain medications used to manage diabetes can dehydrate the body, which increases the risk of heat exhaustion and heat stroke.
In states like Alabama, Georgia, and Mississippi, where diabetes rates are among the highest in the U.S., residents are at higher risk of heat-related complications. Dehydration, dizziness, and even heat-induced changes in blood sugar levels are common occurrences in diabetic patients during heatwaves.
Effects on Kidney Disease
Kidney disease is another major health condition worsened by extreme heat. The kidneys play a crucial role in regulating fluid levels in the body, but high temperatures can disrupt this balance. Heat causes dehydration, which puts additional strain on the kidneys, potentially leading to acute kidney failure or exacerbating chronic kidney disease.
Many people living in Southern states have high rates of kidney disease, making them particularly vulnerable to heat-related kidney complications. Dehydration is a key concern for these individuals, as it can quickly lead to life-threatening conditions if left untreated.
States Most Affected by Extreme Heat
While the entire U.S. is experiencing rising temperatures, certain regions are more vulnerable due to their climate and the prevalence of chronic health conditions. The National Weather Service has issued heat warnings across Southern and Southeastern states, including:
– Florida
– Georgia
– Kentucky
– Mississippi
– Oklahoma
– Texas
– Virginia
– The Carolinas
These states have some of the highest rates of chronic diseases in the country, making residents particularly susceptible to heat-related illnesses. The combination of extreme heat and prevalent chronic conditions creates a dangerous situation, especially for older adults and people with compromised health.
The Role of Hospital Systems in Managing Heat-Related Illnesses
Healthcare systems in the Southern states are under immense pressure during extreme heat events. Hospitals are seeing increased numbers of patients suffering from heat-related complications such as heart failure, dehydration, and heat stroke.
Dr. Joanne Skaggs, associate chief medical officer of adults at OU Health University of Oklahoma Medical Center, reports a significant increase in patients coming to emergency departments with heat-related symptoms, including dizziness and dehydration. This surge in cases puts a strain on hospital resources, especially in regions where healthcare access is already limited.
Long-Term Consequences of Heat on Health
The long-term effects of extreme heat on people with chronic conditions are profound. Prolonged exposure to high temperatures can cause lasting damage to the heart, kidneys, and other organs. Repeated heat stress can also lead to a decline in overall health, increasing the likelihood of hospitalizations and even death.
In the future, as climate change continues to drive up temperatures, the frequency and intensity of heat waves are expected to rise. This will place even greater strain on individuals with chronic diseases and the healthcare systems that care for them.
Conclusion
Extreme heat is more than just an uncomfortable inconvenience—it is a serious health threat, particularly for the millions of Americans living with chronic conditions such as heart disease, diabetes, and kidney disease. As temperatures continue to rise, especially in the South and Southeast regions, healthcare systems must be prepared to manage the growing number of heat-related health complications.
The importance of preventive measures, such as staying hydrated, avoiding strenuous outdoor activities during peak heat, and seeking medical care at the first sign of heat-related illness, cannot be overstated. For those with chronic conditions, managing heat exposure is a matter of life and death.

Frequently Asked Questions (FAQs)
1. How does extreme heat affect people with heart disease?
A. Extreme heat increases the workload on the heart, making it harder for people with heart disease to maintain a healthy body temperature. This can lead to heart failure or heart attacks.
2. Why are people with diabetes more vulnerable to heat?
A. People with diabetes often have poor circulation, which makes it difficult for their bodies to cool down. Medications used to treat diabetes can also increase the risk of dehydration during heatwaves.
3. What can people with chronic kidney disease do to protect themselves during extreme heat?
A. Staying hydrated is essential for people with chronic kidney disease. They should also avoid strenuous activities in hot weather and seek medical help if they experience symptoms of dehydration.
4. Which regions in the U.S. are most affected by extreme heat?
A. Southern and Southeastern states, including Florida, Georgia, Mississippi, and Texas, are most affected by extreme heat, as these regions have both high temperatures and high rates of chronic disease.
