Neurologists and psychiatrists cited by the outlet point to sleep apnoea, restless legs syndrome, fragmented sleep, chronic stress, irregular schedules and late screen use as possible causes. Nutritional deficiencies, thyroid disorders, autoimmune disease, chronic pain and mental health conditions may also contribute. Dr Shubha Subramanian of Kauvery Hospital said eight hours is generally adequate, but sleep quality can be affected by medical disorders or deficiencies. Dr Vivian Kapil of SRM Prime Hospital advised medical evaluation when fatigue lasts two to four weeks, particularly with snoring, headaches, low mood or concentration problems. ## Coverage - timesnownews.com Tags: fatigue, mental health, nutrition, sleep, sleep disorders Canonical: https://indianopinion.org/eight-hours-of-sleep-may-not-prevent-daytime-fatigue-doctors-say/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
