Advice from Quironsalud: Taking care in high temperatures

Heart failure, diabetes, kidney disease and COPD are chronic pathologies that are most aggravated by high temperatures. If you feel dizzy, tired, weak and have cramps, it is advisable to go to a medical centre.

During the summer period and especially with extremely high temperatures, a multitude of chronic pathologies can worsen. “Among the diseases that can worsen are cardiovascular problems such as heart failure and hypertension, diabetes mellitus, respiratory problems such as COPD or asthma, nephrological issues, cerebrovascular issues such as strokes or multiple sclerosis. Even dermatological problems such as acne, rosacea and lupus, and other problems”, explained Dr Jose Luis Lasaga, head of the Quironsalud Alicante Emergency Service.

“The symptoms of this aggravation,” says Dr Fulgencio Molina, head of the Quironsalud Murcia Emergency Service, “can range from a feeling of tiredness, weakness, and cramps, to those that are potentially more dangerous, such as dehydration and ion imbalance. In the face of these symptoms, it is very important to consult a specialist.”

How heat affects each of these diseases

Within cardiovascular diseases, patients with high blood pressure may suffer from hypotension due to heat, with the possibility of dizziness, sweating and loss of consciousness. “In addition,” adds Dr Juan Costell, head of the Quironsalud Torrevieja Emergency Service, “in summer time when routines change, we can be inconsistent with taking medication to treat our illnesses, which can cause an increase in blood pressure.” For his part, adds Dr Lasaga, “patients suffering from heart problems can suffer from dehydration and hypotension since the heart has less reserve capacity to eliminate excess heat from the body and can become overloaded and enter into acute pulmonary oedema. It is important to take into account the medication that patients take, which usually include diuretics and beta-blockers, and adjust them for summer to avoid these problems”.

For their part, diabetic patients are more sensitive to heat. They are at a greater risk of suffering from dehydration and can suffer issues that prevent the sweat glands from regulating body temperature. “This dehydration,” says Dr Molina, “can prompt an increase in glucose in the body, which can cause increased thirst, dry skin, fatigue, blurred vision.” The vasodilation produced by the heat also causes an increase in the speed of insulin absorption, which can lead to hypoglycemia with the onset of dizziness, altered level of consciousness, agitation…”, emphasizes Dr Lasaga.

People with respiratory diseases such as COPD, asthma or bronchitis may have their symptoms aggravated during the summer season due to the increased heat and environmental dryness that increase the amount of work that our body has to do to maintain normal body temperature. “which means an increase in oxygen requirements. In addition to the fact that the increase in heat and pollution increase the concentration of ozone and can trigger an asthma attack”, indicates the head of emergency at Quironsalud Alicante.

Finally, Dr Costell points to an increase in mortality and hospitalizations in patients with end-stage kidney disease.

Advice for chronic patients in the face of high temperatures

Quironsalud specialists recommend following the guidelines below:

• Avoid sudden changes in temperature as far as possible. In the home, the air conditioning must be between 24-26 degrees
• Do not expose yourself to the sun during peak hours of the day.
• Always stay well hydrated and avoid excessive consumption of sugary drinks and alcohol as they can cause problems such as dehydration or arrhythmia
• During long trips, avoid prolonged immobilization and if this is unavoidable in some selected patients, the use of anticoagulants may be prescribed
• Avoid destinations with very hot climates and altitudes above 3000 meters as it causes an increase in oxygen consumption.
• Wear light and breathable clothing.
• Perform moderate exercise only in the hours of lowest temperature.
• It is very important to take care of the diet, increase the consumption of fruits and vegetables and moderate consumption of alcohol, fats and sugar.
• It is also very important not to forget to take the medication and always travel with a medical report.
