Cleanliness particularly in respect of house hold environment is a must as doctors and the environmentalists say as it forms an essential ingredient for better health but it is doctors again who suggest that too much of cleanliness is likely to cause health problems. Ailments like asthma, they say, spread out of a bigger measure of cleanliness. What we have been knowing till now is that major cause of an ailment has its roots in pollution and for that reason much of emphasis is laid on cleanliness. One can't have two extremes at the same time -keeping atmosphere clean and keep pollution by its side the same time. Possibly the answer lies in maintaining a moderate profile by reducing the usage of anti oxidants minimizing the application of anti insects devices including sprays with an intense exposure.
