Seasonal Diseases Occurring in Brazil

The term seasonal refers to the periodicity of certain events. Anything that occurs within a time interval with a beginning, middle, and end and a certain frequency is considered seasonal. In other words, the word refers to that which is temporary and relative to each year's season. In this sense, seasonal diseases are those typically triggered or worsened at a specific time of the year. Differences in temperature and fluctuations in relative humidity favor the development of certain dysfunctions and complicate their healing process, also due to the habits that people maintain due to climate change or the chronological distributions of certain diseases in terms of maximum and minimum records always occur in the same period, whether year, month, week, or day. In these distributions, the variation is characterized by a certain seasonality related to the property according to which the phenomenon always repeats itself in the same season. The objective of this manuscript is to report seasonal diseases occurring in Brazil. To produce this article, a bibliographic survey was carried out in original articles, reviews, and meta-analyses obtained from the PubMed database between the years 1985 to 2024. As a search strategy, the terms used were “seasonal”, “diseases”, “autumn”, “spring”, “summer”, and “winter” terms “or” and “and”. The exclusion criteria adopted were the time limit from 1980 to 2024, no relation to the search strategies, abstracts without a pharmacological aspect of the system of endocannabinoids, and duplicate articles. Finally, they were accessed in full for the construction of this work, totaling 39 scientific works for its development.
