This I the first element in the Healing process when overcoming withdrawal symptoms. Symptom withdrawal is a process the physical body must withstand, from being dependent on drugs to all the withdrawal symptoms, to developing into a healthy and balanced body, freed from addiction and disease.
The Physical Body
Essentially, overcoming your withdrawal symptoms is about making use of the human body as much as you can. This gives several benefits much like: natural tiredness, generation of dopamine, adrenaline, and serotonin along with other beneficial neurotransmitters, which benefits all four categories.
Physical exercise creates sweating and requires vigorous movement and intensity. Think cardio, endurance and strength training. Each of them energize neurotransmitters, the cardio and endurance exercise enhances the detoxification process. The alternate solution for that cardio would be to run-preferably outside, doing laps in a pool, steam sauna, cycling, and sexual activity and so on.
