HOT HOUSE SYNDROME is now making life a living hell for vulnerable people, leaving nearly one in 10 Brits getting ill from soaring temperatures in their own homes, research shows.

The government was today urged to provide targeted support for those in poorly insulated homes as a 34°C heatwave saw Britain declare its hottest day of the year.

Figures from the Warm This Winter campaign showed that 4.5 million people have been made unwell from high temperatures at home — dubbed Hot House Syndrome — in the past 12 months.
