People who are physically dependent to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services frequently include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any complications are resolved as rapidly and safely as possible.
