As the UK swelters through high temperatures, a top cardiologist has highlighted crucial warning signs that could indicate your heart is under strain in the heat. Dr. Roy Jogiya, chief medical adviser at Heart Research UK and consultant cardiologist at Kingston and St Thomas Hospital NHS Foundation Trust, underlined the importance of recognizing symptoms that may signal your heart is “struggling” in hot weather.
During periods of extreme heat, the heart has to work harder to regulate body temperature. Dr. Jogiya explained that the process of vasodilation and sweating, the body’s natural cooling mechanisms, can place additional strain on the heart by increasing the heart rate to pump blood through widened blood vessels. This heightened cardiovascular effort, particularly in vulnerable individuals, has been associated with a surge in hospital admissions for heart-related issues during heatwaves, including heart attacks and arrhythmias.
People most at risk during hot weather are the elderly and those with pre-existing heart conditions, such as high blood pressure. Dr. Jogiya noted that these individuals may have reduced heart and blood vessel function and be less able to adapt to heat stress, which makes them more susceptible to heat-related heart problems.

Recognizing the warning signs of heart strain in hot weather is crucial. According to Dr. Jogiya, key symptoms to watch for include breathlessness, dizzy spells, chest pain, and fatigue. He emphasized that while heat-related fatigue is common, heart-related symptoms are typically more severe and persistent, often accompanied by chest discomfort or pressure.
Dr. Jogiya offered practical advice for staying safe in hot weather, advising individuals to limit outdoor activity during peak heat, seek rest in a cool environment, and wear lightweight clothing. He also recommended avoiding alcohol and caffeine, which can contribute to dehydration, and using cooling methods like fans or cool showers—especially for those at higher risk.
In conclusion, Dr. Jogiya stressed the importance of remaining vigilant about heart health during extreme heat and taking proactive measures to stay hydrated and rested. Additionally, he emphasized the necessity of seeking early medical intervention if feeling unwell and continuing to take prescribed medications, consulting with healthcare professionals for tailored advice and support.
