As Scotland prepares for its sunniest weekend of the year, with temperatures in Glasgow expected to reach a high of 30°C, health experts are urging individuals, particularly those with high blood pressure, to take precautions during the upcoming heatwave. The warm weather can exacerbate health issues, making it crucial to stay informed about how to manage blood pressure effectively.
Maintaining healthy blood pressure is vital for overall health, as it helps prevent serious conditions such as heart attacks and strokes. High blood pressure, often called a “silent killer,” frequently presents no symptoms, which can lead many individuals to remain unaware of their condition. In the UK alone, over 14 million adults are estimated to have high blood pressure, with many at risk of associated health complications, especially during extreme temperatures.
As temperatures rise, the body tends to sweat more, leading to fluid loss and potential dehydration. According to reports from the British Heart Foundation, this can cause a decrease in blood volume, possibly resulting in lower blood pressure. Such changes can increase the risk of falls and fainting, particularly among individuals with existing heart and circulatory diseases.
Ruth Goss, a Senior Cardiac Nurse at the British Heart Foundation, emphasizes the importance of hydration in maintaining healthy blood pressure levels. She advises, “Water is best, but milk, sports drinks, diluted squash, fruit juice, tea, and coffee all count. If you have been told to restrict your fluid intake, for example, if you have heart failure, speak to your GP or heart failure nurse about alternative ways to keep cool.”
The Mayo Clinic identifies those at higher risk during hot weather as individuals over 50, those who are overweight, or people with heart, lung, or kidney conditions. Certain blood pressure medications can also affect the body’s ability to manage heat. The Medicines and Healthcare products Regulatory Agency (MHRA) has issued guidance for patients, noting that medications like ACE inhibitors, beta-blockers, and calcium channel blockers may hinder the body’s temperature regulation.
Signs of heat-related distress can include cold, clammy skin, confusion, dizziness, disorientation, rapid pulse, fatigue, and headaches. As such, individuals should be vigilant about their health, especially during this heatwave.
To ensure safety during these high temperatures, the Alzheimer’s Society has shared practical tips for individuals with dementia, which are beneficial for anyone spending time outdoors. They recommend wearing light-coloured, loose-fitting clothing made from natural fibres to help prevent overheating. A hat or cap is essential for those who may be outside for extended periods.
During the hottest parts of the day, typically between 11:00 and 15:00, it is advisable to keep curtains and blinds closed in sunny, south-facing rooms and to open windows in the evening to allow cool air in. If outdoors, finding shade, wearing hats, and applying high-factor sunscreen regularly can help protect against heat-related health risks.
For those looking to cool down, simple DIY methods can be effective. Placing a frozen bottle of water or an ice pack next to a fan can create a makeshift air-conditioning system. Keeping cool water easily accessible is also crucial. For caregivers of individuals with dementia, reminders to drink water and providing high-water-content foods such as ice lollies, milk jellies, melon, and yogurt can further aid in hydration.
Angelo Makri, a Senior Knowledge Officer for Wellbeing at the Alzheimer’s Society, urges families and caregivers to regularly check in on individuals with dementia. “As the temperatures rise this week, we are urging families and carers to ensure that people with dementia are staying hydrated, wearing light clothing, and keeping out of direct sun,” he said. A quick visit to check on a neighbor, friend, or family member can make a significant difference in keeping them safe during the heatwave.
As Scotland embraces this warm weather, being proactive about health can help individuals with high blood pressure and other vulnerable populations enjoy the sun safely.
