During the summer months, sweltering heat not only makes daily life difficult but also poses significant health risks for people with chronic conditions. In particular, people with high blood pressure may experience unexpected fluctuations in their blood pressure levels due to the effects of hot weather.

People with high blood pressure are among the highest-risk groups most affected by extreme heat during the summer months. Dr. Selim Özgül, a physician of internal medicine at Medline Adana Hospital, issued warnings and recommendations, stating that simple precautions taken when temperatures rise significantly can help prevent serious health problems.

 Those with chronic conditions are most at risk

In hot weather, blood vessels dilate to help the body cool itself. This can cause blood pressure to drop more than usual in some people. Fluid and mineral loss through sweating can also negatively affect blood pressure balance. Older people, those with heart or kidney disease, and those taking blood pressure medication are particularly susceptible to these changes. A severe drop in blood pressure can lead to symptoms such as dizziness, weakness, a feeling of faintness and loss of balance. In some patients, however, blood pressure readings may actually rise due to the stress caused by hot weather and fluid loss.

Medication should not be altered without a doctor’s advice

Some patients who notice changes in their blood pressure during the summer months may decide to reduce their medication or stop taking it altogether. However, this is a highly risky course of action. The dosage of blood pressure medication should only be adjusted by a physician following an assessment, and only if necessary. It is important for patients to measure their blood pressure regularly, record their readings and consult their physician in the event of any unusual changes. Stopping medication or changing the dose on one’s own can lead to uncontrolled rises in blood pressure and very serious health problems.

Care should be taken regarding water intake and protection from the sun

Drinking sufficient amounts of water in hot weather is of great importance for people with high blood pressure. Drinking water at regular intervals throughout the day, without waiting until you feel thirsty, helps maintain the body’s fluid balance. Avoiding going outside during the hottest parts of the day, staying in the shade, choosing light-coloured, loose-fitting clothing, and avoiding excessively salty foods are among the simple yet effective precautions that can be taken. It is also recommended that strenuous physical activities be carried out early in the morning or in the cool of the evening.

Dietary habits can affect blood pressure

Changes to dietary habits during the summer months can also affect blood pressure control. Whilst excessively salty and processed foods can cause blood pressure to rise, going without food for long periods can trigger low blood pressure. In hot weather, light and balanced meals should be preferred over heavy ones, and daily fluid requirements should be met primarily with water.

Risk symptoms must not be ignored

If symptoms such as severe dizziness, fainting, chest pain, shortness of breath, palpitations, confusion, or very low or very high blood pressure readings occur, you should seek medical attention without delay. Not underestimating the effects of summer heat, keeping up with regular medical check-ups and maintaining healthy lifestyle habits will help people with high blood pressure get through this period more safely.
