The term ‘ritucharya’ is derived from two different words: ‘ritu’ meaning season and ‘charya’ meaning ‘regimen’. Seasonal regimen prescribed for preservation of health and prevention of diseases is termed as ‘ritucharya’.
Ayurveda, the science of life defined the human body (sharira) is always in a state of change towards degeneration called as sharira (human body) [Vaidyaka shabdasindhu]. Ancient scriptures were aware of astronomy; they keenly observed the change in seasons with respect to the sun, moon, stars, wind, and rainfall. The concept of “yat pinde tat brahmande‘- whatever there is in the environment is also there is the human body is applied in understanding health. This leads to appreciating changes in the human body according to seasons and regimens are made accordingly. The seasonal regimen's main aim is to prevent diseases due to the derangement of dosha. Hence ritucharya is one of the ways to be in synchronize with ever-changing nature and being healthy all at the same time.

Contemporary approach and researches
Impact of seasonal variation on health:
All these facts are well studied and presented by Ayurveda scientists along with the management protocol. More over recent studies have shown changes in the biochemical parameters along with seasonal variations. The physical health impacts of climate change, especially infections, allergies, respiratory and cardiovascular diseases are now well recognized. These objective evidences can be considered as a reflection of the physiological imbalance occurring in the equilibrium of tridosha due to seasonal variations, progressing to a pathological state as a result of unhealthy diet and regimen. So, in order to prevent seasonal outbreak of diseases, a regimen should be designed, including currently available facilities. For that a thorough knowledge of the physiological imbalances occurring in various seasons in terms of dosha vitiation, status of agni and bala are very essential.
The season is a variation for a particular time which includes environmental factors which consist of nature of land, water, atmospheric temperature, humidity, wind, rain, clouds and atmospheric pressure. All these factors undergo a continuous change and at a time, when no two movements are exactly alike in a given place.
Some studies are carried out to establish the influence of seasonal changes on the development of opportunistic diseases. These show the effect of photo period on immune function and hormone synthesis has a positive result. It also showed that time of the year is important in changing the glucocortcoid concentrations in unstressed and stressed animals.
A study was conducted to assess the biophysical, and biochemical changes and provocation of tridosha in ritusandhi. It shows that there was a increasing and decreasing pattern in biochemical changes within normal variations, but the changes were not remarkable. The study is also evident of occuring jwara (fever), pratishyaya (rhinitis), alasya (tiredness) frequently with dominance of vata and kapha provocation.
Based on the principles of ritucharya, a study has been conducted on healthy volunteers to assess the bala (physical strength) in different ritus (seasons). The study showed that maximum bala was seen during winter (hemanta ritu), moderate bala during spring (vasanta ritu) and minimum bala during rainy season (varsha ritu). Other systems of medicine also considered the effect of seasons on health. For instance, father of modern medicine, Hippocrates says that whoever wishes to investigate medicine properly should proceed thus in the first place to consider the seasons of the year and what affects of each of them produces. Tibetian system also believes that seasonal regimens are powerful instruments in prevention of diseases.
Variation in state of dosha in different ritu results in diseases if the prescribed regiment is not followed. For example, increased occurrence of flu, dry skin in winter, heat stroke in summer, pollen allergy in spring, high incidence of air and water borne diseases in rainy season and skin diseases in autumn are observed. Few studies show positive correlation between attack of asthma in winter season. Contemporary science also have evidences regarding seasonal affective disorders (SADs).
Understainding of Ayurvedic concept of seasonal divisions (ritu vibhaga) is mainly based on specific characteristic features of seasons (lakshanas), based on the hindu calendar months (masa) and stars (rashi). In present scenario, the characteristic features of classically mentioned characteristic features are not uniform all over the geaographical areas. But still specific features during seasons based on biological and external environmental changes during the each seasons are observed. In this connection, a few reviews eshtablish the relation between ritus and gut microbial changes and their effect on health. The food habits and lifestyle changes during each season (ritu) changes the free living microorganism in gut. This increases individual susceptibility to inflammatory as well as metabolic diseases such as non- communicable diseases. Adopting a proper seasonal regimen including seasonal purification enhances the gut acclimatization, thus prevent the pathological manifestation of seasonal diseases and maintain health.
A seasonal change in immune function has also been observed by researchers during animal studies. Immunological parameters like spleen mass, white blood cells, cellular immunity, IgG and IgM levels showed seasonal changes. Cellular immunity was found to be high in winter than in summer.
