The first thing you can do is to take steps to improve your general health. Make sure any health issues are being taken care of; visit your doctor regularly, make sure your diet is fresh and varied and have a plan to lose weight, if you’re overweight. Also make sure your fluid intake is sufficient and that you’re taking at least 30 minutes of exercise a day.
Stress is an immune system depressor, so try to relax as much as you can. Deep breathing is great for stress relief. Practice this hourly if you’re feeling anxious and make sure that you breathe all the way down into the diaphragm. This will engage the ‘Vagus’ nerve, which has a calming effect.
There are more specific steps you can take to strengthen your immunity. Ensure you have sufficient intake of the following supplements to boost the immune system:
Vitamin D3 – This is probably the most important vitamin for immunity, yet many people are deficient in D3. This applies mainly to those living in a cold climate, as vitamin D is formed by the action of sunlight on the skin. Typically I would advise a blood test to check level of vitamin D, but at this point in time, if you’re living in winter with no sun exposure, grab yourself some vitamin D3 and take at least 1,000 iu a day.
