Physiological detoxification is the process of freeing an addict from physical dependence and generally lasts about 1-2 weeks, although there are specific differences. There are three phases of detoxification, and the physiological detoxification phase is the most difficult one, as the body goes through a very painful detoxification response in order to detoxify. In about 1-2 weeks, the detoxified person will go through the withdrawal reaction and reach physiological detoxification through treatments such as drug substitution decrement, frozen turkey, gradient detoxification and Chinese medicine detoxification. However, after reaching physiological detoxification, they need later positive education, psychological guidance, social help and support, proper physical exercise, improved nutrition and family understanding and support to complete their psychological recovery. In addition, patients need to speed up their own metabolism during detoxification. They can drink more water and eat more watery fruits in order to urinate, and urine can promote the discharge of toxins from the body.
