The Alzheimer's Society in Sussex is urging people to check in on friends and family living with dementia to ensure their safety during the hot weather.
A yellow heat warning remains in effect across the South until 8am Sunday.
Alzheimer's Society in Sussex says there are over 31,600 people across our region living with dementia who will need help.
Dehydration is a common challenge for people living with dementia, as memory problems mean they can easily forget to drink enough water.
Meanwhile, a yellow warning for thunderstorms has been issued by the Met Office, lasting until 6am tomorrow.
