For example, the heart and the rest of the organs have representations on the foot of the person. And it is also believed that the energy flow in the body that goes into every cell does follow a path and this connects a number of organs and glands and there are pressure points present on the feet and the hands. The base of the thumb on the palm where thin loose skin webs it to the side of the palm is the area where the pressure point of the heart is located. Press this area until you feel calm and the chest or heart pain has subsided. Reflexology can be used as first aid in times like these, especially if your senses have gone haywire and you cannot seem to get up to get help. If the person really wants to undergo reflexology, then the treatment can still push through provided that the focus is not on the feet. The reflexology practitioner may focus on the ears of the person. This is also not recommended for people suffering from thrombosis or embolism. In the medical world, this is the obstruction of the pulmonary artery by the blood clot. If you are going to trace the history of this therapy, then you will learn that this practice has been in existence for the past thousands of years. And this practice can be traced to a number of places like in India, China and even Egypt. There is even that wall painting that has been discovered in Egypt that shows two men working on the feet and the hands of two men. Other than these, there are certain requirements that should be satisfied as well before you will be given your national certification. You will be made to undergo some form of on-job training where you will be supervised by an instructor. And more importantly you are expected to pass the national board test. Reflexology promotes relaxation because it allows the blood to circulate and relieve swelling. Reflexologists believe that illness or discomfort is primarily caused by blockages in the veins that prevent the blood and oxygen from passing through. Consistently applying pressure will slowly remove the blockages and allow the nerves to breathe.
