There are many erroneous Prejudices, with Regard to Colds, all of which may be attended with pernicious Consequences. The first is, that a Cold is never dangerous; an Error which daily destroys the Lives of many. I have already complained of it for many Years past; and I have since beheld a Multitude of such Examples of it, as have but too sufficiently warranted my Complaints. No Person however, it is certain, dies merely of a Cold, as long as it is nothing but a Cold simply; but when, from Inattention and Neglect, it is thrown upon, and occasions Distempers of the Breast, it may, and often does, prove mortal. _Colds destroy more than Plagues_, was the Answer of a very sagacious and experienced Physician to one of his Friends, who, being asked, how he was in Health, replied, Very well, I have nothing but a Cold. A second erroneous Prejudice is, that Colds require no Means, no Medicines, and that they last the longer for being nursed, or tampered with. The last Article may be true indeed, with Respect to the Method, in which the Person affected with them treats them; but the Principle itself is false. Colds, like other Disorders, have their proper Remedies; and are removed with more or less Facility, as they are conducted better or worse. Sec. 124. A third Mistake is, that they are not only considered as not dangerous, but are even supposed wholesome too. Doubtless a Man had better have a Cold than a more grievous Disease; though it must be still better to have neither of them. The most that can reasonably be said and admitted on this Point, is, that when a checked, or an obstructed Perspiration becomes the Cause of a Distemper, it is fortunate that it produces rather a Cold, than any very dreadful Disease, which it frequently does: though it were to be wished, that neither the Cause, nor its Effect existed. A Cold constantly produces some Disorder or Defect in the Functions of some Part or Parts of the Body, and thus becomes the Cause of a Disease. It is indeed a real Disorder itself, and which, when in a violent Degree, makes a very perceivable Assault upon our whole Machine. Colds, with their Defluxions, considerably weaken the Breast, and sooner or later considerably impair the Health. Persons subject to frequent Colds are never robust or strong; they often sink into languid Disorders; and a frequent Aptitude to take Cold is a Proof, that their Perspiration may be easily checked and restrained; whence the Lungs become oppressed and obstructed, which must always be attended with considerable Danger. Sec. 125. We may be convinced of the Weakness and Fallacy of these Prejudices, by considering attentively the Nature of Colds; which are nothing else than the very Diseases already described in the three preceding Chapters, though in their greatest Degree only.
