The Centers for Disease Control and Prevention updated its adult sleep guidelines in June 2026, raising the recommended minimum from 7 hours to 7.5
hours per night for adults aged 18 to 60, citing a decade of new research linking sleep duration to cardiovascular and cognitive health outcomes.

Key Developments
The CDC now also recommends a consistent sleep and wake schedule within 30 minutes on weekdays and weekends, acknowledging that irregular sleep timing independently
increases cardiometabolic risk even when total hours are sufficient.
According to the CDC’s own National Health Interview Survey data, 35 percent of US adults currently report sleeping less than 7 hours on a

What Experts Are Saying
A meta-analysis of 87 studies covering 4.2 million participants, published in The Lancet in 2025, found that adults sleeping 6 hours per night had
a 32 percent higher risk of type 2 diabetes, 26 percent higher cardiovascular disease risk, and 22 percent higher all-cause mortality compared to those

sleeping 8 hours.
Cognitive research from the University of Washington found that sleeping under 7 hours for three or more consecutive nights produces cumulative impairment equivalent to missing 24 hours of sleep.
The impairment persists even when subjects report feeling rested. See also: World Cup 2026 June 19: USA vs Australia, Brazil vs Haiti.
The updated guidelines separate sleep duration from sleep quality recommendations for the first time.
Adults who spend 8 hours in bed but have poor sleep efficiency below 85 percent are now flagged for clinical follow-up rather than simply told to go to bed earlier.
Sleep scientists recommend setting a fixed wake time first, then working backward to determine bedtime.
A consistent wake time, even on weekends, is the single most effective behavioral intervention for improving sleep consistency.
Light exposure is the primary driver of the circadian clock.
Morning bright light within 30 minutes of waking and reduced blue light exposure from screens after 9 PM are recommended by the CDC’s supplementary guidance document.
The CDC recommends adults aged 18 to 60 get at least 7.5 hours of sleep per night, increased from 7 hours in the previous 2016 guidelines.
Adults aged 61 and older should aim for 7 to 9 hours.
The guidelines now also emphasize a consistent sleep schedule within 30 minutes on all days of the week.
Research consistently shows that weekend recovery sleep does not fully offset weekday sleep deprivation.
Studies find that the cognitive performance benefits of weekend oversleeping disappear within two days of returning to insufficient sleep.
The CDC’s new guidelines specifically discourage irregular sleep timing as independently harmful regardless of total hours.
Sleep efficiency below 85 percent, meaning less than 85 percent of time in bed is spent asleep, is a clinical marker of poor sleep quality.
Other indicators include taking longer than 30 minutes to fall asleep, waking more than once per night, feeling unrefreshed upon waking, or excessive daytime sleepiness despite adequate hours.
