Dr Pixie McKenna is crunching the NHS’s health data to reveal what made us sick in 2016. She believes if we understand when and how the nation falls ill, we’ll all have a better chance of staying well in the year ahead.

Every time any one of us goes to the doctor, collects a prescription, signs up for a fitness regime or just buys some headache tablets – that information is recorded. So today we’re building a more accurate picture of the nation’s health, faster than ever before.

Dr Pixie reveals what this data says about our health and how we can learn to avoid seasonal spikes in injuries, infections and even accidents.

If you want to know how changing the clocks could be a health hazard, why when the kids go back to school it’s not just cases of cold and flu that rocket, how when it comes to cholesterol size doesn’t always matter and why in winter it’s often not cold but dehydration that kills, Dr Pixie has the astonishing answers that could keep you well in the year ahead.
