Sleep Issues and Poor Sleep
Sleep is when the body repairs, the brain consolidates memory, and hormones reset, so poor sleep quietly undermines nearly every part of health. Difficulty falling asleep, waking through the night, and never feeling rested are common complaints, and they often point to imbalances beneath the surface rather than simply bad habits. Understanding what disrupts sleep is the first step toward restoring it.
Sleep concerns are evaluated by Dr. James Petros, MD, founder of NexGen Health and a physician board certified in Functional Medicine, Anti-Aging Medicine, Regenerative Medicine, Physical Medicine, and Interventional Pain Management. A Tulane University School of Medicine graduate trained at Stanford, Dr. Petros founded the practice in 2021 to deliver personalized, science-driven care, treating sleep as a foundation of overall health.
Signs of Poor Sleep
Sleep problems take many forms, and their effects often show up during the day as much as at night.
- Trouble Falling Asleep: lying awake despite feeling tired.
- Frequent Waking: interrupted sleep that breaks the night into pieces.
- Early Waking: waking too early and being unable to return to sleep.
- Unrefreshing Rest: waking tired even after enough hours in bed.
- Daytime Fatigue: low energy, poor focus, and irritability during the day.
- Racing Mind: difficulty quieting thoughts at bedtime.
Why Sleep Suffers
Poor sleep often stems from more than habits. Hormonal shifts, including changes in cortisol, melatonin, and sex hormones, can disrupt the sleep cycle, as can chronic stress, nutrient deficiencies, blood sugar swings, inflammation, and aging. Underlying issues like hormone imbalance, metabolic dysfunction, or sleep apnea frequently make sleep worse, so identifying the specific drivers is what allows real, restorative sleep to return.
