Dr. _Lind_ says, that People coming first from a cold into a hot Climate are apt to have plethoric Symptoms; a Pain of the Head, Giddiness, a Sense of Weight, and Fulness of the Breast, and a slight Inflammation of the _tunica conjunctiva_; and that some are apt to be seized with ardent Fevers and Diarrhœas. And all Practitioners have observed, that New-Comers into warm Climates are at first liable to Fevers tending to the Ardent, and are very subject to Fevers of the remitting and intermitting Kind, which are the Endemics of all warm Countries at certain Seasons of the Year; and after some Time they are apt to fall into Fluxes, the Yellow Fever, and other Diseases depending on a putrescent State of the Juices. In military Expeditions these Disorders are liable to be complicated with Fevers of the Malignant or Hospital Kind, if Care is not taken to prevent it. And nothing has been found to be more productive of Diseases in those warm Climates, than indulging freely in the Use of Spirits and other strong fermented Liquors; exposing one’s self to the Damps, especially lying on the Ground after the Dews fall; and working hard, or using violent Exercise in the Heat of the Day. The best Preservatives against Diseases in warm Climates have been found to be,--1. Temperance; a Diet of light and easy Digestion, composed more of vegetable than of animal Food; such as a small Portion of fresh Meat, joined with a sufficient Quantity of Vegetables; Rice, _Indian_ Corn, and other Grains, and Roots of various Kinds, prepared in different Forms; well baked Bread; the moderate Use of ripe Fruits; and the free Use of mild cooling subacid Liquors, joined with a small Proportion of vinous or spirituous Liquors; carefully avoiding the too liberal Use of Wine, Spirits, or other strong fermented Liquors.--2. Great Care not to expose one’s self to the Damps of the Night, nor lie down to sleep on the Grass, or in woody moist Places, in the Day; and to avoid all violent Exercise in the Heat of the Sun.--3. Such Means as tend to support the Spirits; for Chearfulness has been observed to contribute as much to the Preservation of Health, as Fear and Dejection of Spirits to the Production of Diseases.--4. Keeping the Body clean, and bathing frequently in the Sea, or in a River, in the Morning.
