Grief is perhaps the most intense form of stress for everyone, muscle tension is a sign your body is preparing for battle known as fight or flight, but the reality is there is nothing we need to fight other than our own stress. When trying to relax, the body not only stops the stress it can reverse the physical illnesses, eg. Fatigue, nausea, shortness of breath and a tight sensation in the throat and chest, headaches and stomach aches. Relaxation will not change the reality of the loss, but it can reduce your physical suffering and help with the sleep deprivation.
