However comfortable this mode of producing warmth in bed may be, it does not protect the lungs from the morbid effects of the distant points of temperature of a warm parlour in the day time, and a cold bed-chamber at night. To produce an equable temperature of air at all hours, I have frequently advised my patients, when going to a warm climate was not practicable, to pass their nights as well as days in an open stove room, in which nearly the same degrees of heat were kept up at all hours. I have found this practice, in several cases, a tolerable substitute for a warm climate. 11. The MODERATE use of the lungs, in READING, PUBLIC SPEAKING, LAUGHING, and SINGING. The lungs, when debilitated, derive equal benefit with the limbs, or other parts of the body, from moderate exercise. I have mentioned, in another place[28], several facts which support this opinion. But too much pains cannot be taken to inculcate upon our patients to avoid all _excess_ in the use of the lungs, by _long_, or _loud_ reading, speaking, or singing, or by sudden and violent _bursts_ of laughter. I shall long lament the death of a female patient, who had discovered many hopeful signs of a recovery from a consumption, who relapsed, and died, in consequence of bursting a blood-vessel in her lungs, by a sudden fit of laughter. [28] An Account of the Effects of Common Salt in the Cure of Hæmoptysis. 12. Are there any advantages to be derived from the excitement of certain PASSIONS in the treatment of consumptions? Dr. Blane tells us, that many consumptive persons were relieved, and that some recovered, in consequence of the terror which was excited by a hurricane in Barbadoes, in the year 1780. It will be difficult to imitate, by artificial means, the accidental cures which are recorded by Dr. Blane; but we learn enough from them to inspire the invigorating passions of hope and confidence in the minds of our patients, and to recommend to them such exercises as produce exertions of body and mind analogous to those which are produced by terror. Van Sweiten and Smollet relate cures of consumptions, by patients falling into streams of cold water. Perhaps, in both instances, the cures were performed only by the fright and consequent exertion produced by the fall. This is only one instance out of many which might be mentioned, of partial and unequal action being suddenly changed into general and equal excitement in every part of the system. The cures of consumptions which have been performed by a camp life[29], have probably been much assisted by the commotions in the passions which were excited by the various and changing events of war.
