Overview
- Roughly 38–40% of people report insufficient or fragmented sleep, with national data in Argentina showing elevated insomnia and post‑pandemic increases in sleep disorders.
- Specialists emphasize three pillars for sleep health: regular timing, adequate duration, and quality, with a target sleep efficiency of about 85% or higher.
- Weekday–weekend shifts known as social jetlag are associated with higher depression risk and biological injury, including muscle‑biopsy evidence of increased inflammation after curtailed sleep in young adults.
- A study presented at the European Society of Cardiology following nearly 91,000 people over about 14 years found that sufficient weekend catch‑up correlated with roughly 20% lower heart‑disease incidence, indicating only partial mitigation.
- Guidance from major sleep organizations urges fixed bed and wake times, morning light exposure, reduced evening screen use, and avoiding late caffeine and alcohol, with brief naps used cautiously during post‑holiday recovery.
