By and large a person can hinder the hypnotic effect by expecting to feel hypnotized.
Whilst it is true that some people do experience physical phenomena whilst in hypnosis it should be noted that these are subjective units and cannot be set in stone as something we should all expect to feel.
Some people feel light, others heavy, warm, cold etc and most people feel nothing at all. Indeed, with “hypnosis Without Trance” as pioneered by James Tripp, the subject/client has their eyes open and is very much a conversational part of the session.
With hypnosis the person should be in a state where the subconscious is open to new ideas and perhaps changing old beliefs. It is a process of the mind and so it generally has very little to do with the physical.
