But if I only get 7.75 hours of sleep or less, my eyes feel tired all day and I&amp;#x27;m only half as productive. I&amp;#x27;ve never understood why there is such a marked difference between eight hours of sleep and almost anything less than eight hours. There&amp;#x27;s something chemically going on inside that I don&amp;#x27;t understand.  The problem I&amp;#x27;m having now is that I can get a good five or six hours but I wake up after that fifth or sixth hour and can&amp;#x27;t get back to sleep long enough to get that ideal eight. This problem is seriously affecting my career and I don&amp;#x27;t know what to do.  I do do moderate to vigorous exercise five times a week but that doesn&amp;#x27;t always help.</text><parent_chain></parent_chain></comment><story><title>A report on exercise and sleep (2021)</title><url>https://rubenerd.com/a-report-on-exercise-and-sleep/</url></story>
