Ayurveda, an ancient traditional life and medical science, is a significant part of Indian heritage. It is considered a sacred science that benefits humans not only in this life but also beyond. Ayurveda proposes various theories to maintain individual health, such as Dinacharya, Ritucharya, and Ratricharya. According to Ayurvedic literature, the year is divided into Uttarayana and Dakshinayana, with each Ayana further divided into three Ritu. The Indian calendar recognizes six seasons, resulting in six seasonal junctions. At the end of Ritucharya, Vagbhatta describes Ritusandhi, the period when seasons transition. This period includes one week from the ending season and one week from the beginning season. Ritusandhi Charya should be followed based on the local seasonal variations, as seasons are not uniformly experienced everywhere. Individual health is closely linked to a healthy environment, making environmental protection during seasonal transitions crucial. Ayurveda outlines Dincharya, Ritucharya, Sadvritta, and Ratricharya. During Ritu Sandhi (seasonal junction), the immune system weakens, creating favorable conditions for disease spread. Understanding Ritu Sandhi is essential for adjusting food habits and daily routines to prevent Sandhi Kaalgat diseases (e.g., swine flu, viral fever, cough, and cold). This article emphasizes the concept of Ritusandhicharya over Ritucharya.
