Ayurveda, or Ayurvedic Medicine, is a system of Hindu traditional medicine of Vedic origin which is native to the Indian sub-continent. Ayurveda is a Sanskrit word for life-knowledge. In Ayurveda, the most important factor in determining pathology is how healthy the person is, in order to be able to defend themselves from any internal or external pathogens. Everything is based on how healthy the body is, and the health parameter to determine this measure of health is how pure or how clean the system is.

“Chrono” means time and “Biology” means the study of life. Chronobiology creates a lifestyle according to specific changes which are innate in your body. This means we have an internal clock and this internal clock determines the production of hormones and, when coupled with exposure to light, it creates photoperiodism. The earth rotates so there is sun at midday and when the sun goes down at 6 o’clock for example, there is no more thermal emission, no more ultra violet and, so on.

Molecular biology is the study of molecular underpinnings of the process of replication, transcription, translation and cell function. It is a branch of science that investigates biological activity at the molecular level, particularly the interactions between various systems of a cell and the structure, function and regulation of proteins and nucleic acids essential to life. It overlaps with biochemistry and genetics with particular focus on DNA, RNA and protein biosynthesis.

Any organism requires a specific environment to survive or thrive. The expression of genes is triggered and associated with specific physical and biochemical stimuli. Temperature can be a trigger for functions that when decoded by genes will activate thermogenesis or heat dispersal. The function of skin pigments such as melanin also depends on how the environment, spanning generations, acted as a master control for genes that needed to adapt and produce more dark skin pigment when living at locations that induced more sun exposure.

Emerging sciences such as nutrigenomics, and exposomics are delving deeply in the subject of how the environment and the partial introduction of it in our body in the form of food, air, water can influence cells to activate definite functions. It is obvious that certain diet types trigger inflammation genes, and others switch them on. Investigation on which molecules trigger deeper processes such as regeneration, growth, apoptosis are also investigated.

Semeiotics studies signs and symptoms of the human body to correctly identify, collate and interpret, through diagnostics, the origin of simple or complex diseases. It can also identify the patterns of normality and therefore those conditions that could be pathologic in certain constitutions and are normal for others, such as heart rate, cholesterol, perspiration etc.

Our physical traits and characteristics offer deep insight into the health or dysfunction of our body. Signs such as striations in fingernails may indicate mineral deficiencies, cracked skin vitamin deficiency, finger length may indicate hormonal dominance, texture of the tongue organ dysfunction, and so on.

It has been widely accepted that human conscious activity seems to be highly related to brain cortical activity, however conscious activity has been demonstrated anecdotally with minimal or nil activity via electroencephalography. Subconscious processes refer to all physiological functions that we do not consciously influence. They are autonomic in essence but can be highly disrupted by cognitive and cortical stress.

Genetic lineage has a significant influence on our ideal environment and lifestyle, and subsequent defense systems for our health. For example, a person with genetic history from England who is living in Australia will be more prone to sunburn and diseases of a hot environment.
