Exercise daily to keep your body and immune system strong. Minimize using shampoo with chemicals, you may even wash your hair without any shampoo and just use a bit of lemon juice with water to rinse. It is best to avoid eating foods that are uncooked (raw), greasy, salty, spicy and chocolate. No smoking, drinking alcohol, coffee and cold beverages. Do get to bed by 11 pm at the latest and sleep soundly through the night so that all systems can recover from the day’s activities.
