The portal European Journal of Heart published a study revealing the cardiovascular risks posed by people suffering more than 8 hours.
The American Academy of Medicine Sleep and Society of Sleep Research recommend the best long & # 39; sleep for adults is 7 hours each night, however, it is unclear whether the excessive length of & # 39; sleep or naps during the day can expose people to greater risk & # 39; CV death and illness.
In the study investigated the association estimated length & # 39; total sleep & # 39; day and & # 39; & # 39 a day; during the day with & # 39; death and major events & # 39; QoL in the study & # 39; The Prospective cohort epidemic Urban Urban (PURE), which included 116 632 participant, international regions followed for a median of & # 39; 7.8 years.
The study showed that an estimated & # 39; total time & # 39; sleep & # 39; 6 to 8 hours a day was associated with a lower risk & # 39; death and major cardiovascular events. Besides the duration of sleep, naps during the day were associated with & # 39; increased risk & # 39; CV events and mortality in large & # 39; those older than 6 siefa of & # 39; overnight, but not those who sleep less than 6 hours per night.
These findings are consistent with recent meta-analysis showed an association in & # 39; & # 39 form, and between risk of increased CV and daytime naps and duration of & # 39; sleep. However, this study can & # 39; help generalized findings ethnic groups and different geographical regions. Given the strong international prospective design and its great. In addition, it presents evidence & # 39; increased risk & # 39; CV associated with & # 39; daytime naps in & # 39; & # 39 subjects with; length & # 39; sufficient sleep overnight.
This study provides important epidemiological information, but the causal factors explain the associations described by & # 39; & # 39 higher risk, remain speculative CV (home place).
Case between older
Among adults, sleep disorders and related symptoms & # 39; sleep as the day of sleepiness, nocturia, dyspnoea and pain at night & # 39; morning headaches are common and are often associated with & # 39; cardiovascular disease, lack of & # 39; adherence to medications, heart disease and mortality from all causes.
Naps during the day can represent a physiological response to disturbed sleep related disease, even in & # 39; people last normal sleep. F & # 39; this study, the group with the longest period & # 39; sleep (10 hours) had a relatively higher prevalence of & # 39; factors & # 39; CV risk, and a higher proportion of & # 39; children took the day (71.6%), almost triple that of the reference (6-8 hours), which was only 27.4% of participants reported naps during the day.
Relationship between the day and daytime events & # 39; CV
It can & # 39; potentially indicates that subclinical CV undiagnosed disease can & # 39; explain part of the association between daytime and on important events & # 39; & # 39 CV in; patients & # 39; sufficient length & # 39; night's sleep. Interestingly, in & # 39; those long & # 39; short-term & # 39; sleep at night, daytime naps may represent a compensatory mechanism for deficit and debt sleep and, therefore, were not associated with & # 39; higher CV risk.
Conclusions not very clear
F & # 39; others, naps during the day may be related to & # 39; factors and cultural practices, as shown by the wide variation in intra naps reported in & # 39; this study. If "compensatory naps" and "usual naps" are associated with & # 39; comparable CV risk, regardless of NAPs cause, remains & # 39; unclear and was not further investigated in the present study.
