Heart conditions
Hot weather can put extra strain on the heart. Stay hydrated (unless advised otherwise), avoid strenuous activity in peak heat, and seek medical advice if you develop worsening breathlessness, dizziness, swelling or chest discomfort.
Respiratory conditions
Heat, humidity and poor air quality can worsen asthma and lung conditions. Continue prescribed medication, carry your reliever inhaler, check air quality/pollen forecasts, and seek advice if symptoms worsen.
Diabetes
Hot weather can affect blood glucose levels and increase dehydration risk. Check glucose regularly, store insulin/medicines correctly, drink water often, and seek advice if blood sugars become difficult to control.
Kidney disease
People with kidney disease are at higher risk of dehydration in hot weather. Follow your fluid advice, watch for dizziness, headaches or reduced urine output, and contact your healthcare team if concerned.
Dementia and cognitive impairment
People with dementia may not recognise overheating or dehydration. Offer regular drinks, keep rooms cool, encourage lightweight clothing, and check regularly for signs of dehydration or heat exhaustion.
Mental health conditions
Hot weather can affect mental wellbeing and how the body regulates temperature. Stay connected with family, friends and support services, keep regular routines where possible, and seek help if your mental health worsens.
