Why Does Blood Pressure Change in Summer

2025-07-21

How does heat affect blood pressure

  • In hot weather, the body tries to cool itself down. As a result, blood vessels dilate, and blood pressure may drop.
  • High temperatures increase heart rate, which puts extra strain on blood pressure.
  • Sweating leads to loss of fluids and salts, which can alter how medications are absorbed and how effective they are.

 

Possible consequences

  • Sudden drop or spike in blood pressure
  • Weakness, dizziness, arrhythmia
  • In some cases – emergency intervention

 

How to protect yourself from blood pressure fluctuations in summer

  • Monitor your blood pressure regularly, especially in the morning and evening
  • Drink plenty of water
  • Avoid direct sun exposure during peak hours (12:00 – 17:00)
  • Do not take medications without consulting a doctor
  • Avoid skipping meals, as low blood sugar can worsen your condition

 

When to seek medical advice

  • If your blood pressure is unstable
  • If you take multiple medications
  • If you have chronic diseases such as diabetes or kidney problems
