An inflammation of the sinus and nasal passages, sinusitis often leads to sinus infections. Contributory factors are nasal irritants such as exhaust fumes, cigarettes, smoky places, dust and pollen; allergies, often to dairy products and wheat, which are mucus-forming; plus a weakened immune system. Too much alcohol, fried food or stress, or lack of sleep and overeating all weaken the immune system. Vitamins A, C and zinc, among other nutrients, help boost immunity. Essential fats are also needed to control inflammation.
For some sufferers the major problem of insomnia is waking up in the middle of the night; for others it is not getting to sleep in the first place. Both can be the effect on the nervous system of poor nutrition or too much stress and anxiety. Calcium and magnesium have a tranquillising effect, as does vitamin B6. Tryptophan, a constituent of protein, has the strongest tranquillising effect and, if taken in doses of 1,000–3,000mg, it is highly effective for insomnia. It takes about an hour to work and remains effective for up to four hours. While tryptophan is non-addictive and has no known side effects, its regular use in not recommended – it is better to adjust your lifestyle so that no tranquillising agents are needed.
