'Check on elderly neighbours and friends'

An amber cold-health alert is in place for the whole of England, including Sussex

Elderly and vulnerable people are being urged to take extra measures as Sussex faces below zero temperatures.

The UK Health Security Agency (UKHSA) has extended an existing amber cold-health alert across England until 12:00 GMT on Sunday.

The warning means those over 65 or with health conditions are most at risk of illness, including strokes, heart attacks and chest infections due to the cold weather.

East Sussex County Council (ESCC) has said homes should be heated to at least 18C in daylight hours and advised people to check on elderly relatives and friends.

Haywards Heath and Horsham are expected to see lows of -4C on Thursday, while the majority of East and West Sussex will see freezing temperatures during the week.

ESCC advised residents: "Wear thin layers to stay warm, check on elderly neighbours and friends. Avoid unnecessary journeys."

The council says young children can also be at risk from cold or damp homes.

Meanwhile West Sussex County Council referred residents to the UKSHA website for advice.

An amber alert means the health service is likely to see an increased demand, according to the UKSHA.

Clinical director at NHS Sussex, Dr Richard Fieldhouse, said: "With temperatures dropping and frost becoming a regular sight, cold weather isn't just uncomfortable, it can be dangerous, particularly for older people and those with health conditions."
