*Climate change has a profound effect on human health and well-being. The impact of climate change on human well-being goes beyond mortality; even birth rates and sperm counts appear to be affected by meteorological phenomenon.25,26,27

Jaiswal Rahul et al, 2011, in a clinical survey39 found a significant relation between seasonal variation and prevalence of some diseases viz. jwara (viral fever), amlapitta (acid peptic disorders), tamaka shvasa (bronchial asthma), pratishyaya (rhinitis) and sirashula (pittaja sirashula and ardhavabhedaka – migraine). They also observed that there is seasonal variation in the state of agni and bala strength) of the person, as stated by our ancient seers.

*Nathani Neeru et al, 2013, in a clinical research40 found that maximum number of patients of tamaka shvasa (bronchial asthma) were registered in winter seasons (hemanta and sishira), 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. Out of 140 cases about half were observing ritucarya occasionally and less number of cases were found to adhere with ritucarya regularly. About two-third cases were bathing with cold water in winters and less number of cases were in the habit of daily head bath.This clinical study based on subjective parameters revealed that in patients of group A (treated with modern drug) and in group B (treated with modern drug along with observance of proper ritucarya of different seasons, highly significant improvement was observed in all symptoms. On intergroup comparison (Chi-square test) patients of group B showed significant rate of improvement in many symptoms like dyspnea, wheezing, cough, rhinorrhea, and frequency of attack and duration of attack. Inter group comparison between group A and B (unpaired t test) had shown statistically significant increase in FVC, FEV1 and PEFR of group B cases as compared to the patients of group A at different follow-ups. These finding suggest that ritucarya has a definite additive effect along with standard drug therapy in the treatment of tamaka shasa (bronchial asthma).
