Can self-hypnosis improve memory?

Yes, self-hypnosis can improve memory. According to Dr. David Spiegel, hypnosis can enhance recall by inducing a state-dependent memory where being in a particular mental state can help one access memories related to that state. For example, individuals who have experienced trauma may use hypnosis to better access and process traumatic memories by being in a mental state similar to the one experienced during the trauma. This process is seen as beneficial in treating trauma-related disorders 1.

Additionally, Dr. Andrew Huberman explained that non-sleep deep rest (NSDR) techniques, such as hypnosis or yoga nidra, have been shown to accelerate learning and retention. This is due to their ability to induce sleep-like states that enhance neuroplasticity, the brain's ability to change in response to experiences. Studies suggest that engaging in these practices after periods of intense focus can increase learning speed and the duration of information retention by approximately 50% 2.
