Robert Bradshaw explains: "High temperatures and humidity can be a bad combination for anyone who suffers from high blood pressure, as the hot weather causes the heart to beat faster, circulating twice as much blood around the body. Also, some blood pressure medications like beta blockers and diuretics can affect the body's ability to stay hydrated or respond to high temperatures."
He encourages anyone with a background of high blood pressure to consume adequate fluids to remain hydrated. He also recommends avoiding the sun and remaining in a cool setting where feasible, and wearing a hat if going outside.
When temperatures rise, your body must work harder to sustain a normal core temperature, which can place extra pressure on your heart, lungs, and kidneys. This can heighten your risk if you already have a cardiac condition.
It's essential to keep cool and maintain hydration. Remaining properly hydrated by consuming sufficient fluids can help compensate for the additional perspiration you lose and prevent your blood pressure from falling too low.
The pharmacist added: "You should also monitor your blood pressure regularly during the heatwave. If it's high or you are experiencing any worrying symptoms like extreme tiredness or confusion, a rapid pulse, excessive sweating, headaches, swelling in your arms and legs or nausea, seek urgent emergency medical advice."
