In Neurolinguistic Programming, uptime refers to a state of mind in which the attention is entirely focused on external sensory input. This is the opposite of downtime (ie. hypnotic states) in which all or most attention is focused inward. Uptime can be used to improve sensory acuity and therefore the ability to calibrate properly. One important characteristic of uptime is the "complete absence of internal dialogue." Uptime states often occur naturally, especially in high-stress situations.

Uptime training can be very helpful for people who are overly self-conscious. It can also be helpful for people who get lost in their own little world.
