Ayurveda considers the body as comprising of three important constituents i.e. ''Vata'', ''Pitta'' and ''Kafa'' which can be equated to their nearest English terms as''Air'' ''Bile / Acidity'' and ''Phlegm''. Any imbalance in them is considered as a causative factor for a particular disease. The different seasons of the year contribute to either their balance or imbalance in them.
Also body goes through every phase(4hrs) twice every 24 hour. The time is local time.
get up before 6am, 5 is optimal and you will be active all day, 10am-2pm is the time frame for the biggest meal. 2pm-6pm time for intencive exercises, 9-10pm time to go to bed.
