Doctor shares how to boost immune system to 'rarely get sick'

Doctor shares how to boost immune system to 'rarely get sick' Dr Mark Hyman has shared some simple tips to help people stay well through the winter A world-renowned doctor has revealed how to "build an immune system that rarely gets sick" this autumn and winter. Dr Mark Hyman is an American physician, author and podcast host who has millions of followers across various social media platforms. He frequently shares his medical knowledge with his online fans, and in a recent post he explained that "cold and flu season starts with the basics". He added: "Your immune system responds to everything you do. What you eat, how you sleep, how you move, and how you handle stress." Dr Hyman went on to highlight that poor sleep, under- or over-exercising, chronic stress, sugar and ultraprocessed food, low nutrient levels, and an unhealthy gut can all undermine your immune defences. Conversely, getting plenty of rest, quality movement, and consuming whole foods can have precisely the opposite effect. Reducing stress, optimising nutrients, and using sauna also deliver significant benefits, he noted. Dr Hyman further stressed the importance of sufficient vitamin D to "modulate your immune system". Focussing on "farm" ingredients you can incorporate into your diet, he encouraged people to use: "Ginger and turmeric to calm inflammation. Garlic which is antimicrobial and antiviral. Sauerkraut and miso for your microbiome. Artichokes for prebiotic fibre. Colourful plants for phytochemicals." Dr Hyman added: "Your body has an amazing capacity to protect itself when you give it the right support. Start with the foundations, test your vitamin D, and prioritise sleep. That's how you stay well all season." When to take a vitamin D supplement According to UK Government guidance, everybody should think about taking a daily vitamin D supplement throughout the autumn and winter months (from October 1 to late March ), as the body produces vitamin D through direct sunlight on the skin when outdoors. However, between October and early March, we are unable to generate sufficient vitamin D from sunlight alone.
