Sleep Medicine: Satisfied with your sleep? Sleep may have a greater effect on the body than you think.

A good time and quality of sleep is one of the things many people expect.
but sleep is affected by a variety of factors, such as social or sleep environment and personal behavior, psychological, physical and chronic diseases, which lead to many people sleep time disorders (insufficient or excessive sleep), poor sleep quality.
, especially among older people, sleep problems are more common, affecting more than half of them.
sleep time disorders and poor quality increase the risk of certain diseases, such as cardiovascular disease, depression, etc., and accelerate the aging process.
disease will have a negative impact on physical and mental health, which in turn harms sleep time and quality, forming a vicious circle.
sleep time disorders and poor quality were also associated with co-illness.
so-called co-illness refers to the simultaneous suffering of two or more diseases.
According to a study published online in Sleep Medicine, too long, too short and poor quality in middle-aged and older people increases the risk of depression, cancer, diabetes, heart failure, and kidney disease.
To assess the link between sleep time and quality and co-illness, researchers from Western University in Canada analyzed data from the Canadian Longitudinal Study of Aging (CLSA), involving more than 30,000 subjects aged 45 and over.
the study, the participants were collected on their age, gender, height, weight, and lifestyle and medication.
based on the average sleep time of the subjects over the past week, the researchers divided the subjects into three groups: those who were less than 6 hours, those who were 6-8 hours and those who were more than 8 hours.
, depending on the subject's satisfaction with their sleep quality, the subjects were divided into dissatisfied or very dissatisfied groups, general groups, and satisfied or very satisfied groups. the
researchers also counted the prevalence of 17 chronic diseases, including anxiety or depression, cancer, cardiovascular disease, chronic obstructive pulmonary disease or asthma, colorectal problems, diabetes, heart failure, hypertension, kidney disease or failure, musculoskeletal problems, obesity, osteoarthritis or rheumatoid arthritis, osteoporosis, gastric disease, stroke or transient cerebral ischemia, thyroid problems, and urinary system problems.
statistics, 67.9 per cent of women and 57.9 per cent of male subjects had at least two types of co-illness.
tend to be older, older, past or present smokers, regular or occasional drinkers, and less physically active.
factors such as smoking, alcohol consumption, physical activity, and education, the researchers found that sleeping too little or too much increased the risk of co-illness.
The risk of developing the disease increased by 16% and 44%, respectively, among female subjects who s stayed less than 6 hours and more than 8 hours, compared to those who s stayed 6-8 hours, and by 2% and 45% respectively among male subjects.
effect of sleep time on co-risk varies greatly from age to age.
among those aged 45-54, subjects who s had less than six hours of sleep and more than eight hours had a 27 percent and 64 percent increased risk, with the most significant association.
participants aged 55-64, 65-74 and 75-85 who s seded more than eight hours increased their risk by 61%, 28% and 19%, respectively.
risk of co-existing diseases among other age groups with less than 6 hours of sleep was not statistically significant.
satisfaction with their sleep quality will also affect the occurrence of co-illness.
had a 14 percent and 20 percent increased risk of developing the disease compared to the women and men in the group who were dissatisfied or very dissatisfied with their sleep, while the women and men in the group who were satisfied or very satisfied with their sleep quality had a 13 percent and 12 percent reduced risk, respectively.
The risk increased by 23 points among subjects aged 55-64, 65-74 and 75-85 who were dissatisfied or very dissatisfied with their sleep quality compared to subjects with average sleep quality subjects aged 45-54, 55-64 and 75-85 who were satisfied or very satisfied with their sleep quality had a 26%, 11% and 10% reduced risk, respectively.
because the study was observational, it only showed a link between sleep time and quality and an increased risk of co-disease, and did not prove a causal relationship.
and quality of sleep in the study, which was largely dependent on the participants, may have an impact on the results.
the researchers analyzed a correlation between co-morbidity and sleep time and quality, and that lack of sleep or poor sleep quality had harmful effects on heart metabolism, endocrinology, immunity, and inflammatory pathologies.
previous studies have found that sleep deprivation affects hormones that control appetite, glucose stability and cortisol levels, and is also associated with changes in circulating uterine levels and neurotrophic responses.
mechanism between poor sleep duration and increased incidence of co-morbidity is poorly known.
long sleep duration, especially in older men, and there was a consistent association with poorer physical health.
sleep duration may be the result of chronic diseases or side phenomena, rather than risk factors, although further research is yet to be confirmed.
, lead author of the study and Professor Kathryn Nicholson of the University of Weston, said: "High-quality sleep is beneficial, but achieving high-quality sleep can sometimes be a challenge.
we should make sleep one of the key health indicators, ideally with a sleep assessment that focuses on the quality and duration of sleep, especially in patients with multiple diseases.
Recommended by the American Sleep Foundation, the optimal sleep time for adults is 7-9 hours, for older adults 7-8 hours, for children aged 6-13 9-11 hours, and for 14-17-year-olds 8-10 hours.
For when to fall asleep, there is no particularly accurate sleep time, after all, everyone will have different rules of rest, as long as according to their own actual situation, to meet the recommended sleep time of the corresponding age is good.
