The main things you can do this winter to avoid the coronavirus are to maintain social distancing measures, wear masks and wash or disinfect your hands at every opportunity. It is also important to have a healthy, balanced diet inclusive of 10 portions of multicolored fruits and vegetables a day. It is important to stay hydrated and to keep the airways in your mouth and nose warm when you go outside into the cold weather, this stops them drying up and becoming more susceptible to infection. Sun lamps can counteract some of the lack of sunshine in the winter months and can be useful to boost vitamin D levels and immunity, though they must be used in moderation according to manufacturer’s guidelines.
There are various supplements you can take to boost immune function and help improve viral defense at the lung nose and throat membranes where the virus attaches. These include: Vitamin D, Vitamin C, Zinc, Echinasia, Green tea, Beta Glucans, N-Acetylcysteine (NAC) or Glutathione, Vitamin A, Quercetin, Elderberry and Andrographis paniculata. You may wish to add some of these to your daily regimen.
