Brief: Hormones are catalysts which begin and end processes of digestion, emotion, thought, action. They are normally drawn upon for specific short-term tasks. Once released into the body, they are best dissipated by the action they are associated with. Too much presence for too long will produce too much wear and tear one's health apart. Chronic high levels of hormone presence indicates imbalance.
The discovery of human hormones is relatively recent in human history. Relatively few were in the literature until 1990. Now, we are aware scientifically of perhaps over 100. Awareness of them and their attributes is minimal throughout the population. The less we know of ourselves, the less we can understand and manage ourselves.
The unaware and undisciplined person is likely to have difficulty stemming the distractions which will make clear access to one's Higher Self impossible.
The person who only knows of the "blueprint" given them by their institutional mentors is equally disadvantageous for they will constantly be trying to maintain attachment to such a blueprint and have difficulty being open and confident enough to receive uncontaminated Spiritual Guidance
Appreciate WHY you want to know something about hormones.
Do you want to know what your natural ones are for healthfulness?
Do you want to avoid excessive or decreased availability of them?
Do you want a hormone directed function enhanced?
Do you want a hormone directed function depressed?
Do you want to know how they work in your body?
Searching for anything can quickly overburden you with information that has no relevancy if you have no focus. If you have a focus, remain open to the possibility that relevant information May come from sources which seem irrelevant in the beginning. I found a book on Pregnancy to be a source of little known Contraception information.
Health is all a matter of what is needed for Your lifesystem to be at its optimum, on a day-by-day and hour-by-hour basis. The less self-aware you are, the greater the opportunity for the inclusion of destabilizing factors and sources to upset your health.
