The 36 libraries across the county offer the devices for free to members, who can use them at home to check their blood pressure daily. They come with a guide on how to measure blood pressure, interpret the results, and a diary to log them. High blood pressure is often called ‘the silent killer’ as it usually presents no symptoms, making regular blood pressure checks crucial for early detection and management. There may not be a single cause for high blood pressure in many people, but maintaining a healthy weight, reducing salt intake, being physically active, keeping alcohol consumption within recommended guidelines, and stopping smoking can all help reduce blood pressure. "A blood pressure check can be done at your GP surgery, local community pharmacy or through initiatives like the library blood pressure monitor loans in West Sussex."
