Is sleeping on air bed harmful for prolonged periods of time? - sleeping bed

My brother was sleeping in the bed of the air around 6 years. He did it in school, and now his own apartment and a job has, he is still sleeping in a bed of air.
Are there any short-or long-term complications for a person to an air bed for a longer period of time?
