<p style="text-align:justify;">This chapter describes seasonal regimen of diet and lifestyle for preservation of health. The year is divided into seasons  based upon the changes in environmental conditions, temperature, day-night cycle and circadian rhythm. Being an integral unit of the nature, these seasonal changes in nature affect human physiology too. Therefore, one must follow the specific regimen for maintaining the equilibrium of body components in harmony with nature. The seasonal regimen is designed on the basis of changes in the [[dosha]], [[bala]] (strength), and [[agni]] (digestive power). This chapter continues the study of dietary regimen from the preceding chapters by adding the dimension of time and seasonal variations to it. </br>

The last seven days of preceding [[ritu]] and first seven days of following [[ritu]] are together known as [[ritusandhi]] (meeting of two seasons). During this period the regimen of the previous season should be discontinued gradually and those of the succeeding season adopted slowly. Particular [[padamshika krama]] (sequential regimen) has to be adopted i.e. Unhealthy things which one has become accustomed should be discontinued gradually. Similarly healthy things (food etc.) should be made use of (gradually) with intervals of one, two or three days.[Cha.Sa.[[Sutra Sthana]] 7/36-37]  On the other hand, if they are discontinued or adopted suddenly, diseases due to unaccustomed foods and activities develop.<ref> Vridha Vagbhata. Sutra Sthana, Cha.4 Ritucharya Adhyaya verse 21. In: Shivaprasad sharma, Editor. Ashtanga Sangraha. 3rd ed. Varanasi: Chaukhamba sanskrit series office;2012</ref> It is a significant advice, as the changeover of external environment from one season to other is very rapid, but our endogenous system needs some time for smooth change over.

Many diseases described in [[Ayurveda]] have their own peculiar causes to develop in particular season, like [[jwara]], [[tamaka shvasa]], [[pratishyaya]], [[amlapitta]], [[shirahshula]], [[sandhi-shula]], [[atisara]], [[sheetapitta]], [[kushtha]] etc.

#[[Jwara]] (fever) is of two types, viz., [[prakrita]] (natural) and [[vaikrita]] (unnatural) based on prognosis. On the basis of [[prakriti]] (basic constitution) of time the fever is termed as [[prakrita]] (natural). [[Kaphaja jwara]] occurs in [[vasanta]] and [[pitta]] dominant in [[sharada]] (autumn), are known as [[prakrita'' (normal) and are easily curable, while [[vata]] dominant [[jwara]] in [[prakrita]] season ([[pravrita]]) is not easily curable. Fever occurs in seasons other than that responsible for vitiation of the concerned [[dosha]] is known as [[Vaikrita]] (unnatural) which is troublesome. [Cha.Sa.[[Chikitsa Sthana]] 3/42]

#[[Tamaka shvasa]] (bronchial asthma) is aggravated by cloudy, cold, rainy weather and easterly wind and [[kapha]] increasing factors. On the other hand warmth relieves the symptoms.

#[[Pratishyaya]] (rhinitis): Seasonal irregularity is one of the causative factors of [[pratishyaya]].[Cha.Sa.[[Chikitsa Sthana]] 26/104]  Thus [[pratishyaya]] can occur in any season if we do not follow seasonal regimen and especially in exposure to too much of cold.

*Nathani et al, 2013, in a clinical research<ref> Nathani Neeru et al, 2013 </ref> found that maximum number of patients of [[tamaka shvasa]] (bronchial asthma) were registered in winter seasons ([[hemanta]] and [[shishira]]), [[vasanta]] and [[varsha]]. These seasons were the predominant period of asthma attack in majority of cases. In maximum number of cases the attack of [[tamaka shvasa]] gets precipitated by intake of [[kapha]] and [[vata]] vitiating [[sheeta]], [[guru]], [[madhura]] and [[amla]] [[rasa]] predominant [[ahara]] like ice-cream, cold drink, cold water, fruit juices, curd, sweets, rice, pickle, salad with lemon etc. in all seasons.
