| Time to effects | In the studies covered by the Trauer et al. meta-analysis, improvement was assessed after completing a CBT-I program, typically lasting 4 to 8 weeks of regular sessions, with effects sustained in long-term follow-up. | Disruptions to the GH pulse and cortisol rhythm appear after just a few nights of shortened or fragmented sleep; improvement after restoring regular, sufficient sleep is usually visible within several days to about two weeks. |
| Who it's for | People with chronic difficulty falling asleep or staying asleep, persisting for at least three months | People doing strength or endurance training, for whom GH-dependent tissue recovery has practical relevance |
