| Time to effects | A subjective improvement can be noticeable after a week or two of consistently applying the principles, though for chronic insomnia sleep hygiene alone usually isn't sufficient and needs to be supplemented with a structured therapy like CBT-I. | 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 | Generally healthy people wanting to maintain or improve already-decent sleep quality through simple, low-risk behavior changes | People doing strength or endurance training, for whom GH-dependent tissue recovery has practical relevance |
