If the stress will make your mind and body un-stable, the relaxation stage on the other hand will ensure that your body and mind will be on the right balance. And aside from those physical effects of relaxation, it is shown as well that this will increase the person's energy and focus and can also help alleviate pain. However, that feeling is only caused by the swelling brought about by the hormonal changes in the body during this time of the menstrual cycle. Constant pressure applied to this area will relieve affected females of the menstrual pain that could often lead to being immobile for a day or two. Pain relievers have been formulated to help ease the pain; however, some users of this drug have developed immunity to its numbing effect that they are required to take large doses before finally feeling the ease. This was first known as the 'Zone Therapy' and it was the American surgeon named William Fitzgerald who first studied these. In the studies that was conducted by Dr. Fitzgerald, he noted that there are zones that can be found on the hands, the feet and the tongue of the person and that all these zones are linked or connected to the many parts of the body. Here are some of these reactions that are associated to treatment: The person may feel enhanced energy after the session, or the person may feel that strong desire to sleep. There will be relief from pain as well, and some people will talk about more mobile joints. There will be times that the patients may cite tiredness and some would even report flu-like symptoms. Do not squash or over press any of your reflexology points because that could lead to injuries and bruises. When you are at work in an office where you are tied to your computer the entire day, you will most likely suffer from a stiff neck. Keeping a good posture the entire day can be tiresome but bad posture can be injurious. Apply pressure just below the knuckles on the back of the hand and on the palm for the pressure points of the chest, breast, lungs and upper back. 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.
