portal Eurpean Heart Journal A study published revealing cardiovascular risks presented by people who sleep more than 8 hours.
The American Sleep Medicine Academy and the Sleep Research Association recommend that the optimal sleep time for adults is 7 hours per night. However, it is not clear that excessive sleep time or intervals during the day may expose people to risk of death and CV disease.
In this study, a total of 116 632 participants in the cohort urban urban epidemic (PURE) study investigated the relationship between total daily sleep and day sleep with estimated daily lifespan and lifelong daily life. International regions lasted 7.8 years.
The study revealed that the estimated total sleep time of 6 to 8 hours per day was associated with the lowest risk of death and major cardiovascular events. In addition to sleep time, daytime drowsiness was associated with greater CV events and increased risk of death in those who did not sleep more than 6 hours, but did not show sleep less than 6 hours a night.
These findings are consistent with recent meta-analyzes showing an U-shaped relationship between increased CV risk and daytime sleep and sleep time. However, this study may help to generalize findings to different ethnic groups and geographical regions. Strong, due to the great international potential design. In addition, it provides evidence of increased CV risk due to daytime sleep in individuals with adequate sleep time during the night.
This study provides important epidemiological information, but causal factors describing the relationships identified with a higher risk of CV remain speculative (house figure).
The situation between elderly people
Sleep disorders and sleep-related symptoms, such as daytime sleepiness, nocturia, night dyspnea and morning headache, are common problems among adults, and are often associated with cardiovascular disease, lack of compliance with drugs. Heart disease and mortality from all diseases.
Daytime sleepings may even represent a physiological response to disturbing sleep related to the disease, even in people with normal sleep time. In this study, relatively higher CV risk factors were observed in the group with the longest sleep duration (10 hours) and the highest percentage of children (71.6%) was approximately three times that of the group. only 27.4% of participants who reported drowsiness during the day (6-8 hours).
Relationship between daytime and CV events
This may indicate that undiagnosed subclinical cardiovascular disease may explain the relationship between daytime sleep and significant CV events in patients with adequate sleep time at night. Interestingly, sleep sleep and short-term sleep sleepers may be a compensatory mechanism for sleep deprivation, and therefore were not associated with a higher CV risk.
Results are not very clear
In others, daytime sleeps may be related to cultural factors and habits, as demonstrated by the wide-range variation in the gaps reported in this study. It is unclear whether "compensatory drowsiness" and "usual drowsiness" are related to the risk of a comparable CV, regardless of the cause of necrosis, and are not further investigated in the present study.
