Causes
Low resistance to infection is often caused by

1. poor and unbalanced diet and deficiency of certain nutrients, particularly Vitamin C,
2. ignoring the importance of daily normal bowel movement,
3. spasm or congestion in intestines and constipation due to stress, bad food etc.
4. toxic or irritating smell of paints, cosmetics etc.,
5. cooking spices, perfumes, pollens, dust, infection from other suffering from cold, toxins accumulated in the system..
6. over consumption of so called good food and taking lots of tea, coffee, medicines,
7. living in a highly polluted locality, poor ventilation, lack of exercises, insufficient sleep, sexual excesses, impure air, polluted water,excessive work, strain, worries or other mental factors, all of which add their quota to our adverse living conditions.
   According to the views of the author, cold is not a disease but it is a healing crisis - when toxins are accumulated in the body, these find some outlets in the form of cold and fever which serve as safety valves and enable the body to cleanse itself as the toxin accumulations have exceeded the point of tolerance. As the cold constitutes the curative process, it would be wrong to attempt to suppress or abort it and stop the body from doing what is wants to do and needs to do. So it is a mistake to look upon the cold as something harmful, instead it should be recognised as a healing effort on the part of the body.It is only when the workload is too great for vital organs like the stomach, lungs and kidneys that Nature uses the cold as a Safety valve.

Treatment
Fortunately, the treatment is quite simple and costs nothing. It entails the exercise of a little WILLPOWER and intelligence, but surely that is not asking for too much. If the person wants to get well,a little sacrifice is a small price to pay for relief. The most important factors in preventing cold or reducing its severity are fasting, enema, diet and Yogic Kriyas plus exercises - all of which can be learnt by anyone very easily. Natural living habits are the best guarantee for good health and of course, freedom from cold.Every time the cold is suppressed unnaturally like with medicines it inevitably leads to serious illness. If we suppress this, where does the accumulated harmful material ( which is being expelled ) go ? Obviously it will be driven into glands, muscles, joints and organs or retained in the body to play havoc again. So it is entirely justifiable to say that safety valves should not be closed or blocked by suppressing cold.
The prevention and cure is simple living based on Natural laws as explained below :

1. Fasting and enema should be taken up intermittently, besides vigorous exercises and Yogic kriyas. Sufficient sleep and rest/ relaxation are fundamental to a high degree of resistance to infection.
2. Eat less and cut down on starchy food, tea,coffee, fried and fatty food. Cultivate the habit of eating vegetables, fruits, cereals, sprouts and drinking juice and soups which will provide sufficient nutrition (minerals and vitamins,particularly A & C) - Such a diet will move your bowels freely and regularly.
