Overview
- A longevity physician quoted in recent coverage warned that regularly sleeping under seven hours may accelerate biological aging by reducing cellular repair, weakening immunity and harming brain health.
- Medical and sleep specialists say most adults need about seven to nine hours of nightly sleep while children and teens require roughly eight to 11 hours for growth, memory consolidation and immune development.
- Psychologists identify fear of sleeping (somnifobia), hypervigilance and stress-driven intermittent insomnia as common causes of repeated night awakenings that keep the nervous system in a state of alert.
- Clinicians recommend evidence-based treatment such as cognitive behavioral therapy for insomnia, stable bedtimes, limiting evening screens, and avoiding clock-watching or forcing sleep, which can prolong problems.
- With summer heat worsening sleep loss, doctors advise cooling tactics—chilled pillow covers, exposing more skin to air, and pre-bed cooling routines—and urge parents to preserve children's sleep schedules during vacations.
