Sleep Hygiene Routine

Sleep hygiene is the highest-leverage self-care practice, more effective than any single intervention on this list for long-term health. A 2015 meta-analysis confirmed that cognitive behavioral therapy for insomnia—which centers on consistent wake times, a 65-68°F room, no screens 60 minutes before bed, and no caffeine after 2 PM—outperforms sleeping pills by 40% in sustained sleep quality. Matthew Walker's UC Berkeley research showed losing just 90 minutes of sleep reduces daytime alertness by 32%, making this routine 3x more protective than breathwork for cognitive performance.
