Yes. Heat can be especially challenging for some people who have survived a stroke. Depending on the effects of the stroke and any other health conditions, you may have trouble noticing heat, moving to a cooler place, or regulating your body temperature. Some medications can also affect how your body responds to hot weather.
A previous stroke does not mean you will have heat illness, but it is worth planning ahead. If you are unsure about your personal risk, ask your healthcare professional how to stay safe in hot conditions.
Stroke can affect people in different ways. Weakness or limited mobility may make it harder to reach water, adjust clothing, or leave a hot room. Changes in sensation or communication may also make it difficult to recognize discomfort or tell someone you need help.
Dehydration is another concern. You may need assistance getting a drink, or you may have swallowing difficulties that require a specific fluid plan. Follow your care team’s instructions rather than changing fluid consistency or intake on your own.
Our team recommends making a practical hot-weather plan with your healthcare professional or caregiver:
Heat stroke is a medical emergency. Call 911 if someone exposed to heat becomes confused, faints, has a seizure, or has very hot skin. Move them to a cooler place and begin cooling them with cool water or wet cloths while help is on the way.
Call 911 for sudden signs of a new stroke, such as face drooping, arm weakness, or speech difficulty. Note when the symptoms started and do not wait for them to pass.
Heat can also endanger pets. For dog-specific warning signs and emergency steps, see our guide to spotting heat stroke in dogs.
Heavy sweating, dizziness, headache, nausea, weakness, and thirst can be signs of heat exhaustion. Move to a cool place, use cool wet cloths, and seek medical help if symptoms worsen or do not improve promptly.
