People living with some long-term health conditions may be more at risk of dehydration, overheating and heat-related illness during hot weather. The following advice can help you stay safe and well.
Mental health conditions
Some mental health conditions and medications can affect the body’s ability to regulate temperature or recognise when someone is becoming unwell. If you have a mental health condition, you should:
stay connected with family, friends and support services
maintain regular routines where possible
seek help if you feel your mental health is worsening during periods of hot weather
Dementia and cognitive impairment
People living with dementia may be less likely to recognise when they are becoming too hot or dehydrated. Families, carers and support workers can help by:
offering regular drinks throughout the day
ensuring living spaces remain as cool as possible
encouraging the use of lightweight clothing
checking regularly for signs of dehydration or heat exhaustion
Kidney disease
People with kidney disease can be at increased risk of dehydration and heat-related illness. If you have kidney disease, you should:
follow any individual fluid advice provided by your clinical team
monitor for symptoms such as dizziness, headaches or reduced urine output
contact your healthcare team if you have concerns about fluid intake or symptoms
Heart conditions
Hot weather causes blood vessels to widen, making the heart work harder to maintain blood pressure. People living with heart failure, coronary heart disease or other cardiovascular conditions may find their symptoms become worse during extreme heat.
If you have a heart condition, you should:
stay well hydrated unless you have been advised to restrict fluids
avoid strenuous activity during the hottest parts of the day
seek medical advice if you experience worsening breathlessness, dizziness, swelling or chest discomfort
糖尿病
Heat can affect blood glucose levels and increase the risk of dehydration. Some diabetes medications and insulin may also be affected by high temperatures. If you have diabetes, you should:
check your blood glucose levels regularly, particularly if you are feeling unwell
keep insulin and other medicines stored according to the manufacturer’s instructions
drink water regularly and be alert to signs of dehydration
seek advice if your blood glucose levels become difficult to control
Respiratory conditions
People with asthma, COPD and other lung conditions may find that hot weather, humidity and poor air quality can worsen their symptoms. If you have a respiratory condition, you should:
continue using prescribed inhalers and medications
carry your reliever inhaler when out and about
monitor local air quality and pollen forecasts if these are known triggers for you
seek advice if your symptoms become difficult to manage
If you are concerned about your symptoms or need advice, contact your GP practice, NHS 111, or your specialist healthcare team.
