Sea survival experts from the University of Portsmouth have been sharing their latest research with the RNLI. Around 60 per cent of deaths in cold water happen within the first few minutes of entering the water.

The scientists are using an extreme environment lab with chambers capable of simulating temperatures as low as minus 25 degrees. Their data may help improve survival rates.
