Firstly many of us need to understand that most of the diseases is not due to pathogens. Most of your symptoms are related to simple indigestion
. Our obsession with hygiene apart the general level of cleanliness isn't an issue nowadays. Only the oils and substances used are most of the time the culprit. More important being the time of their consumption.
A golden rule worth remembering is to go empty stomach when you have any such indigestion related issues and wait for the ultimate signal of preparedness of your stomach - hunger before filling it up. In most instances in my practice of Style Medicine, I have observed that simple physiological knowledge is more rewarding than pathological doubts. Rest along with fluids and rice is enough to kick start your day quickly.
