During the winter months, here in the UK, days are short and there isn’t enough sunlight for most of us to make the vitamin D we need. Taking a tiny vitamin D supplement is a minute change that could have a huge impact on our health. Professor David Llewellyn from Exeter University explains to Michael that vitamin D helps clear abnormal proteins, such as amyloid plaques and tau, from the brain, which may help protect you from dementia. Having enough vitamin D can also boost your immune systems, making that common cold easier to recover from. It could even lift your mood! Volunteer Baljit tries making vitamin D a habit.

We all know that walking is hugely beneficial for our health and wellbeing, but we can get even fitter, and use nearly twice as many muscles, by introducing some poles and a simple technique. Join Michael Mosley as he delves into the science of Nordic walking to find out how it can enhance our walks by burning more calories and helping to ease back pain. He speaks to Dr Jennifer Reed from the University of Ottawa Heart Institute about her research, which has demonstrated why Nordic walking is one of the best forms of exercise for improving your heart health. Our volunteer Jessica picks up some poles and transforms her regular walks into a full-body workout.

Humans have been making music for thousands of years, but for Michael Mosley and our volunteer Matthew, the musical journey is only just beginning. Playing a musical instrument has been shown to strengthen your memory and lift your mood. It can even reduce chronic inflammation. Dr Sofia Seinfeld from the Open University in Catalonia tells Michael why it’s never too late to start making music, and how it can enhance your cognitive abilities by activating regions of the brain associated with motor co-ordination and the processing of emotions. Meanwhile, Matthew gets to grips with the ukulele to see if he can master a tune and boost his wellbeing.

The Mediterranean diet has been shown to be one of the healthiest in the world, and a major component of this is olive oil. Dr Bill Mullen from the University of Glasgow tells Michael about his recent research, which found that two tablespoons of olive oil a day can significantly reduce biological markers of heart disease. Meanwhile our volunteer Ellen, an avid home cook, reaps the benefits of switching to olive oil.

Enjoy Olive Oil

There’s no question that exercise is important for our health, but many of us find it difficult to fit into our busy schedules. In this episode, Michael Mosley explores how high-intensity interval training, HIIT for short, might be the most time-efficient way to get fitter.

Martin Gibala, Professor of Kinesiology at McMaster University in Ontario, reveals all about the beneficial impact of HIIT on your cardiorespiratory system, your ability to control your blood sugar levels, and your risk of chronic diseases. Meanwhile, busy mum and NHS worker Suzanne finds HIIT a great way to incorporate a workout into her hectic routine. Series Producer: Nija Dalal-Small
