ANSWER: Shingles are a recurrence of the varicella-zoster virus, also known as chickenpox. The virus stays in your body and can reappear years later because of a weakened immune system due to stress. You want to boost your immune system and reduce stress. Natural remedies to boost your immune system include Vitamin D3 and the herb Echinacea. There are many natural ways to calm nerves including aromatherapy using calming essential oils like lavender or drinking chamomile herbal tea. To relieve the itch of the rash that occurs, dab apple cider vinegar onto the affected area. You can also apply aloe vera gel to soothe pain and itching. Deep breathing is a great stress reliever and is recommended to take 10 deep breaths each morning and evening before bed. Shingles can be contagious to people that have never had chickenpox so be mindful of keeping the area covered and/or washing your hands often.
