The total root pressure is reduced under a variety of climatic, natural, unnatural, and humane conditions, which causes the absorption rate to be slightly slowed or, in some cases, completely stopped altogether. Simply put, this causes negative pressure, also known as tension, to build up in the xylem vessels, which run from the surfaces of the leaves to the tips of the roots and up the stem.

Their actions cause the xylem to take up water from the stomata. According to root pressure theory, water rises upwardly in the xylem due to a positive pressure developed in the root. Paresthesia (sensations such as numbness, tingling or a pins and needles feeling) is one of the six Ps of arterial disease: Pulselessness, pain, pallor, poikilothermy (body temperature that varies with environmental temperature), paresthesia, and paralysis.
