A hot summer day can leave anyone feeling drained. The lack of energy, difficulty sleeping and constant search for shade are experiences many people know well.
But for millions of people living with chronic health conditions, extreme heat may pose challenges that go far beyond simple discomfort.
According to health experts cited by organizations including the Cleveland Clinic, Cedars-Sinai, the American Migraine Foundation and the World Health Organization (WHO), prolonged exposure to high temperatures can place additional pressure on the body and increase the risk of complications for certain medical conditions, reports Unilad.
When the body works harder
During periods of intense heat, the body must work harder to regulate its temperature. Blood vessels widen, sweating increases and the cardiovascular system takes on extra demands to prevent overheating.

For some individuals, this added strain can affect heart health. Elevated temperatures may contribute to changes in heart rate and blood pressure, particularly among those who already have underlying cardiovascular issues.
Four conditions to watch
Medical experts say these health problems may become more difficult to manage during heatwaves:
- Heart conditions
- Kidney stones
- Gout
- Migraines and recurring headaches
Dehydration is a common factor linking many of these conditions. When the body loses fluids faster than they are replaced, urine becomes more concentrated, increasing the likelihood of kidney stone formation.
Fluid loss can also contribute to gout flare-ups and trigger headaches in susceptible individuals.

Staying safe in hot weather
The WHO recommends limiting outdoor activity during the hottest hours of the day, seeking cool environments whenever possible and paying close attention to hydration.
Experts also advise keeping living spaces cool by reducing direct sunlight indoors and improving airflow during cooler evening hours.
As temperatures continue to climb across parts of the United States and other regions worldwide, health professionals say understanding how heat affects the body could help people reduce risks and avoid preventable medical problems.
