The Truth About Boosting Your Immune System

BBC1, 9pm Perhaps you never used to think about your immune system, but it’s a subject that’s now hard to get away from in our newly health-conscious era thanks to Covid.

A&E doctor Ronx Ikharia presents this documentary that’s been well tailored to answer sensible, practical questions. Does exercise help to improve our chances against viral or bacterial infections? How much harm does alcohol do? And should we be popping supplement pills – or simply thinking more carefully about what goes into our diet?

Plus, we follow a group of volunteers over six weeks as they find out whether what they eat and when they sleep affects their health. Volunteering herself, Ikharia proves to be a straight-talking expert whom viewers can readily understand. You’ll come away knowing far more about your immune system. ★★★★☆
