UK coronavirus live: Exercise cuts risk of Covid death as Boris Johnson warns of third wave

Regular exercise cuts the risk of dying from infectious diseases such as Covid-19 by more than a third, according to new research.

An international team of scientists found 150 minutes a week of physical activity that gets you slightly out of breath can have a massive impact on immunity.

It suggests exercise can reduce fatalities by 37%, the danger of even catching similar diseases by 31% and boost the effectiveness of vaccines by up to 40%.

It comes after Mr Johnson acknowledged soaring cases overseas and warnings from scientists that there will be another wave this year.
