Dreams

Introduction: The Two Pillars of Restorative Sleep # Most people obsess over the number on their sleep tracker, fixating on whether they logged seven or eight hours. But what if the entire focus is wrong? What if the quality of your sleep, specifically the architecture of your sleep cycles, matters far more than the raw duration? This is not a minor distinction. Two people can sleep the exact same number of hours and wake up in completely different states. One feels refreshed, mentally sharp, and physically recovered. The other feels groggy, achy, and mentally foggy. The difference often comes down to sleep architecture: the proportion of time spent in deep slow-wave sleep versus REM sleep, and whether those stages occur at the right times and in the right amounts.
