"Many people don't realise that common medications can make it harder for the body to regulate temperature," Neil explained. "In older adults, the combination of medicine, pre-existing health conditions, and limited mobility can be dangerous in a heatwave."

He said the most common medications that may increase heat risk include:

• Diuretics (water tablets) – often prescribed for high blood pressure or heart failure; they increase urination, which can lead to dehydration.

• Beta-blockers – can reduce the body’s ability to cool down by lowering heart rate.

• Antidepressants and antipsychotics – may impair the brain's ability to regulate heat.

• Antihistamines – can block sweating, increasing the risk of overheating.

• Certain Parkinson's or Alzheimer's drugs – can interfere with body temperature control.

Neil said if you are taking any of these medications: "Always speak to a GP or pharmacist if you're unsure about your medication in hot - don't just stop taking them."

There are ways you can keep your homes cool during a heatwave according to the expert who shared some top tips to not getting heat exhaustion. These include:

• Block direct sunlight – Close blinds and curtains during the hottest part of the day (11am–3pm).

• Create airflow – Open windows at opposite ends of the house early morning and late evening for cross-ventilation.

• Switch off unnecessary tech – TVs, laptops, and kitchen appliances can generate additional heat.

• Use a fan safely – Position it near a bowl of ice or frozen water bottles for an improvised air-con effect.

• Stay downstairs – Heat rises, so lower floors tend to stay cooler.

• Avoid cooking with ovens – Opt for light, cold meals or use a microwave where possible.

"Even a few degrees can make a big difference to vulnerable people. If you have elderly neighbours or family, check in, make sure they’re drinking water, and help them keep their homes cool and safe," Neil further added.
