Overview
- Specialists cited by El Imparcial report that sleeping too little or too much is linked to higher risks for heart disease, type 2 diabetes, depression and early death.
- Age‑based guidance recommends 8 to 10 hours for teenagers, 7 to 9 hours for most adults, and 7 to 8 hours for people 65 and older.
- Sleep adviser Juan Nattex says the body cannot store rest like a battery and argues that you cannot make up for lost hours by oversleeping on weekends.
- Nattex also warns about phones before bed and compares teen use to taking a line of cocaine, a forceful opinion as research focuses on blue light delaying melatonin and hurting sleep quality.
- Separate nap advice from a neurologist says a short siesta before 3 p.m. and under 30 minutes can boost alertness without disrupting nighttime sleep.
