Text: The development of the cheap moving picture and musical theaters as factors in the health of the community seems to have escaped the notice of the medical press. To-day every village and hamlet in the United States boasts a moving picture show. In the large cities of the north and cast it is not unusual for a hundred and often more to be in operation. In Europe they are outnumbered only by the public houses and cabarets. As is well known, the great majority of these theaters exist where the population is greatly congested, as in tenement districts and laboring settlements. The reason for this is obvious. It is the patronage of the poorer classes which makes the moving picture industry a paying proposition. These cheap theaters are usually located in old rookeries or poorly paying commercial sites, as abandoned shops of small tradesmen, etc. In the construction or building alteration of these places for their special needs the one object in view is to obtain a maximum seating capacity in as small a space as possible. No attention whatever is paid to ventilation and not the slightest heed given to the simplest sanitary details. The health or comfort of the patron is a secondary consideration. Municipal regulation is limited to ﬁre prevention and safety exits – and this only after several serious catastrophes.
The performances are continuous, and thus an ever-moving stream of humanity, constantly passing in and out, stirs up dust and dirt that verily reeks with tubercle bacilli. The programs in these resorts have been considerably lengthened owing to the keenness of competition. The result is that an audience is conﬁned within these ill-ventilated and poorly sanitated amusement resorts often for more than an hour and a half, breathing in air which has become befouled and disease-laden through lack of sufficient air capacity. The superabundance of carbon dioxid and organic matter in the air gives rise to sick stomach, headache and a drowsy feeling. The small fee of admission is responsible for a class of patronage which is entirely oblivious of the simplest health precautions. Spitting on the floor is a common practice and is allowed to go unnoticed. Signs calling attention to the dangers of the vicious habit of indiscriminate expectoration are rare. The use of the electric fan in certain of these resorts, while refreshing to the overheated patron, also serves to dry up the sputum with greater dispatch, thus increasing its disease productiveness. Cleaning the premises is impossible during the hours of operation, which gives some idea of the amount of ﬁlth that accumulates.
Robust and vigorous individuals employed as singers and musicians, appearing as often as twelve and thirteen times a day in these crowded resorts, soon undergo a remarkable change of health. Poor ventilation produces not only discomfort and loss of energy, but greater susceptibility to disease, especially tuberculosis. Many of the singers are raw amateurs and know nothing of the care and preservation of the voice, and in many instances a voice capable of greater things is lost to the public through exposure to such unfavorable conditions. Laryngeal troubles are a frequent source of annoyance to this class of people through excessive vocal effort and constant conﬁnement. I have treated many of the singers employed by the cheap moving picture shows and found the majority of them to be of a decided phthisical tendency. The ﬁlm operator who is conﬁned cubby-hole at an exceedingly high temperature falls an easy prey to tuberculosis. Constant attendance at the scene of employment, coupled with the irregularity of meals and uncertain hours, is responsible for the fact that many of the male artists become alcoholics. Taken all in all, the cheap provincial picture theater artist has no easy task and sooner or later another victim is enrolled under the banner of the white plague.
The general practitioner is often consulted by a patient complaining of headache and burning eyes which run water as soon as they come in contact with strong light. After a thorough examination, including urinalysis, the patient is referred to an ophthalmologist in order that a refractive error may be corrected and the patient relieved of the heartache and the visual irritation. In a great number of cases the ophthalmologist will report that there is no error of refraction and that he is unable to account for the headache and the running burning eyes. An inquiry into the habits of the patient will elicit the information that he is a devotee of the moving picture show. The constant gazing on a rapidly moving and scintillating ﬁlm with every mental faculty alert to maintain the connection of the story is sufficient to produce an eyestrain of great severity and thus cause headache and burning eves. The only remedy is rest and cessation from this form of amusement. After a few weeks vision becomes normal or nearly so and no ill results are experienced unless the patient resumes his former habits. In many cases the eye trouble assumes a severity that calls for long and persistent treatment on the part of the ophthalmologist.
Moving picture shows in tenement districts and labor settlements should exhibit pictures that tend to elevate the mind and improve the moral condition of their audiences. Pictures portraying scandal, illicit amours and criminal cupidity very often have a debasing effect on a mind that is already morally warped through environment and surroundings, thereby bringing to the surface a latent criminality. If the moving picture shows are to remain, radical changes must be made.
Rigid inspection by the health authorities is absolutely necessary. Proper ventilation by means of exhaust air fans, airifiers and other ventilating appliances and numerous apertures with sufficient air intake must be provided. The number of cubic feet of air necessary for health should be determined by the seating capacity. The ﬂooring should be oiled, not carpeted or covered with dust-gathering material. Plush-covered and velvet-covered seats should also be prohibited for obvious reasons. Suspension of the performance at the end of every ﬁve hours, when the orchestra or seating hall should undergo a thorough cleaning, is of urgent necessity. The cleaning could be accomplished within forty-five minutes by the aid of the vacuum cleaner and should be followed by a draught of pure air throughout the place, it possible. At the termination of the day’s performance the whole resort should be given the proper sanitary attention. Signs should be conspicuously posted as to the evils of spitting.
That a great deal of eye trouble is due to moving picture shows cannot be denied. The singers, musicians and ﬁlm operators of these resorts fall an easy prey to tuberculosis through excessive vocal efforts, constant confinement, irregular habits and long hours. As a disseminator of tuberculosis the moving picture theater ranks high and it will become necessary to enact special health laws to remedy the evil.
Comments: Dr Howard D. King practiced in New Orleans. Early motion picture venues were regularly criticised for their poor hygiene, and the films condemned as the cause of eye-strain. It was common practice at this time for singers to perform in American nickelodeons, along with illustrative slides, in between reel changes.
