Get out in the cold! And maybe not wearing the warmest jacket. The cold activates our winter metabolism, but only when the body realizes it’s winter. This is Styrian pharmacist Alexandra Mandl’s “Is this healthy?” It’s one of the many tips he’s laid out on his podcast – but how cold you can expect the body to be will of course vary from person to person. Mandl is a pharmacist and Vice-President of the Styrian Chamber of Pharmacists. This chapter is about old home remedies and new ways to get over the cold season. In addition to outdoor exercise, vitamins and adequate sleep, hygiene also plays an important role when it comes to avoiding infections. Everything you need to know about the subject is in the section. Spoiler: Selenium and zinc also help the immune system.
