The Body knows what is good for it. It knows when there is a need for food, water, warmth, by making the stomach ache, throat dry, hair stand on the skin and jaw shiver. It detects the parasitic attack on your body by making the skin itch, body temperature rise, eyes to water and nose to sneeze. It is so attuned to the environment that it can detect a threat outside and take necessary actions to protect the life. It may run and hide or it prepares to defend against the possible attack.
In the larger terms, the body make sure that the species survive by motivating, reinforcing and sometimes flat out pushing reproduction. As in the case of women’s menstrual cycle, the hormones secreted and the internal biology is aiming for one goal, one most important goal at least in the term of a human body is the fertilization of the egg that is released along the cycle. The hormones estrogen, progesterone and testosterone are released at the specific time and in specific amount to regulate the body to reproduce. A manipulation of the internal chemistry to encourage fertilization during the time span of the release of the egg/eggs and making the internal chemistry a little hostile when the body knows that fertilization is not achieved better known as Premenstrual Syndrome (PMS).
Our body is extremely intelligent and capable of self regulation. We do not have to do awful lot to sustain it, it just needs support to stay intelligent. It can function to its optimal capacity if we eat well, sleep well and exercise well. In prehistoric times, eating well was easy and a natural choice because whatever food source available in the environment was natural, not adulterated and the over indulgence was not the way of prehistoric humans. Settlements encourage humans to have more food than necessary, the life of travelling and exploring does not lead to over indulgence, accumulation and storage of resources. As the settlement increased and civilizations begin, accumulation of resources including food started and then came the food processing.
Human’s body and organs have not evolved anatomically in a larger scale since 10,000 years, so considering that we have inherited out prehistoric ancestor’s bodies, the more natural the food is, the better support it gives to the body to function. The more processed the food is, the more alien it is for the body and less it can metabolize it.
Getting enough rest is absolutely a defining factor for the body to start again every day with full capacity and reach its potential. Overworking the body without rest is not the sustainable way for a body to stay intelligent. Going back again to our ancestors, we can intuitively tell that their way of life had a lot of physical work including gathering food and going places by foot. To get more restful sleep, it may not be too far fetched to think that to get a body to exhaust to a restful sleep, we need to carry out physical activities to make our body feel that it can take the well deserving rest at the end of the day.
One factor that did not play a dramatic role in our ancestor’s lives was stress. They did face life or death situations that caused fight or flight responses which was necessary stress for the body’s survival but the body went back to the normal relaxed state after removal of the threat. Now is a different story, we are triggering our body into stress by merely our perceptions of the outer world. It can just be a person that is not a physical threat to us but mentally is associated as threat, therefore triggering a fight or flight response. It can be work, relationships or a memory that puts you in the stressed state. When our bodies stay in these prolonged state of stress, the result is disease, allergies, mental health issues and overall hostile internal environment.
It is so crucial for the stress to be managed as stress may hamper the other factors mentioned before as well. Stress impacts the eating tendencies, motivation to do physical activities and sleep patterns to put it most simply. The stress level impacts the chemistry of the body, immune system and organ function that holds us back from having a flourishing life on this earth.
