The Biological Clock is the active intelligence of the body that nature has programmed in the human body so that humans can resonate with the vibratory frequencies of nature and stay healthy.

These Bio-Rhythms coincide with the rising and setting sun and the electromagnetic frequencies emitted by the earth at different times during the day.

Ayurveda has studied these frequencies over 5000 years ago and has mapped these frequencies and has plotted them to various organs in our body, at various time zones of the 24 hour day.

Both in our wakeful and deep sleep states, our organs rejuvenate and work at their optimum levels. Thus, they stay healthy and age gracefully giving us sustained health till the end of our life.

Respecting the Biological clock gives us the best opportunity to stay healthy and fit and not fall sick.

There are various other parameters that also come into play depending on the seasons and their vibrational frequencies. A combination of both these factors is very important to stay healthy.

Planning of food, food combinations and water consumption patterns are all key to the sustainable working of the body.
