Overview
- Medical specialists reiterated on Saturday that adults should aim for about seven to eight hours of sleep each night as the baseline for physical and mental recovery.
- A Hartford HealthCare summary and sleep clinicians reported that seven consecutive nights of higher-quality sleep can produce measurable improvements in mood, cognition, immunity and skin, though the claim has limited independent corroboration.
- Experts advise shaping the bedroom to aid sleep by keeping it cool (roughly 19–21°C), fully dark, screen-free before bed, and using white noise to mask disturbances.
- Clinicians recommend side sleeping—preferably the left side—to reduce snoring and reflux, warn against stomach sleeping because of lower-back strain, and urge testing mattresses and using ergonomic, dual-height pillows for spinal alignment.
- Practical tips include short naps of about 26 minutes to avoid circadian disruption, choosing cool natural-fiber sheets and, where medically appropriate, sleeping without clothes to help thermoregulation, with cautions for people who snore or have sleep apnea.
