Changes

“Seasonal affective disorder” is a condition where depression in the winter and fall alternate with non-depressive periods in the spring and summer. The degree to which seasonal changes affect mood, energy, sleep, appetite, food preference, or the wish to socialize with other people has been called "seasonality." Recent studies have demonstrated that seasonal mood changes are related to the genetic factors. It means that people may have genetically‐determined sensitivity to seasons.

Jaiswal Rahul et al, 2011, in a clinical survey<ref> Jaiswal Rahul et al, 2011 </ref> 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).

*Nathani Neeru 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.
