Weekend Catch-Up Sleep Linked to Lower High-Blood-Pressure Likelihood
A study looked at how weekend sleep relates to high blood pressure.
People who slept about 90 minutes longer on weekends were less likely to have high blood pressure.
This was an association, so it does not prove that extra sleep directly prevents the condition.
The possible benefit was stronger among people who were not physically active.
Sleeping more than four extra hours was linked with a higher risk.
Very large changes in sleep times can confuse the body’s internal clock.
A weekend lie-in may help people recover from a small amount of lost sleep.
However, it cannot fully fix a whole week or longer of poor sleep.
Getting enough sleep during the week, exercising, and keeping a fairly regular schedule remain important.
A seven-year study of nearly 41,000 adults examined weekday and weekend sleep patterns.
About 87 minutes of extra weekend sleep was associated with a 9% lower likelihood of hypertension.
The apparent benefit was especially notable among physically inactive people, whose risk was 6.9% lower.
More than four extra hours of weekend sleep was associated with a higher risk of hypertension.
Experts cautioned that moderate lie-ins may help recovery but cannot replace sufficient weekday sleep or exercise.
- Who
- Researchers at Korea University studied nearly 41,000 adults; Dr Nawon Lee discussed the possible health effects.
- What
- The study examined whether additional weekend sleep was associated with the likelihood of high blood pressure.
- When
- Participants were followed for seven years, from 2016 to 2023.
- Where
- The findings were presented at the European Society of Cardiology congress in Munich.
- Why
- Researchers investigated whether weekend sleep could help people recover from insufficient weekday sleep and reduce hypertension risk.
Moderate Weekend Catch-Up Sleep
Regular, Sufficient Sleep
Short-term recovery
Moderate Weekend Catch-Up Sleep
Researchers said modest weekend catch-up sleep may give the body time to recover from insufficient weekday sleep and may be associated with lower hypertension odds.
Regular, Sufficient Sleep
Experts cautioned that one long weekend sleep cannot completely reverse prolonged sleep loss, which may take several days to recover from.
How much is helpful
Moderate Weekend Catch-Up Sleep
Around 87 minutes of additional weekend sleep was associated with the strongest apparent benefit in the study.
Regular, Sufficient Sleep
More than four additional hours was associated with higher hypertension risk, possibly because greater schedule changes increase circadian disruption.
Sleep versus lifestyle
Moderate Weekend Catch-Up Sleep
Moderate catch-up sleep may offer supplementary benefits, particularly for people with insufficient physical activity.
Regular, Sufficient Sleep
Physical activity remains central to prevention, and weekend sleep should not be used as a substitute for exercise or adequate sleep during the week.
- Participants
- Nearly 41,000 adults
- Study period
- 2016–2023
