Learn More About How Much Sleep Is Needed for Good Health.
You may be at risk for developing a number of chronic conditions if you sleep for five hours or less each night. study
Regularly getting the necessary amount of sleep is linked to better health, which includes increased quality of life, mental and physical health, as well as improved attention, behavior, learning, memory, and emotional control.
According to a recent study using data from 25 years, those who sleep five hours or less each night are more prone to acquire a number of chronic conditions.
The study, which examined the amount of time spent sleeping among more than 7,000 people in the 50, 60, and 70 age groups, was released on Tuesday in the peer-reviewed journal PLOS Medicine.
In comparison to individuals who slept around seven hours a day, the study revealed that persons who consistently slept five hours or less in their 50s were 40% more likely to have two or more chronic conditions identified in the previous 25 years.
In a news statement, the study's principal author, Severine Sabia, from the Department of Epidemiology and Public Health at University College London, stated that "sleep rhythms and sleep patterns alter with age."
Regardless of age, it is advised to get seven to eight hours of sleep each night.
Sabia cited earlier research that suggested sleep durations above or below the advised amount may be linked to a number of chronic conditions.
According to a different US research released last week, Americans frequently get insufficient sleep and those who slept for fewer than seven hours were more likely to have heart disease risk factors.
Sabia and his team looked into whether sleep deprivation increased the risk of many chronic illnesses, and they believe they discovered this relationship.
According to Sabia's findings, a lack of sleep may also contribute to a number of ailments.
Having two or more chronic illnesses at once is known as multimorbidity. With advancing age, it becomes more probable, but the researchers voiced alarm since it seems to be rising in some regions.
Sabia stated that more than half of older persons today have at least two chronic diseases. Multimorbidity is on the rise in high-income nations. This is proven to be a significant public health issue since several diseases are linked to high medical costs, hospitalization, and impairment.
The Whitehall II Cohort Study, a database of more than 10,000 persons who worked in the UK public sector in London when data collecting started in 1985, provided the information for the study.
Following that, participants registered for follow-up appointments to track their health as they aged.
Between 1985 and 2016, they reported their sleep duration around six times. In addition to examining almost 7,000 people in total, the researchers extracted sleep duration data for adults aged 50, 60, and 70.
The next step was to determine whether individuals had any chronic illnesses and, if so, when they manifested.
Diabetes, cancer, coronary heart disease, stroke, heart failure, long-term renal and liver illness, depression, dementia, Parkinson's disease, chronic obstructive pulmonary disease, arthritis, and Parkinson's disease were among the chronic diseases.
According to earlier research on the risk of each chronic illness, sleeping five hours or less each night at the age of 50 was linked to a 20% higher chance of acquiring a chronic disease than people who slept the prescribed amount of hours.
At ages 50, 60, and 70, they discovered that those who routinely slept five hours or fewer had a 30 to 40% higher risk of acquiring various illnesses than people who slept around seven hours per night.
The researchers also discovered that people who claimed to have slept five hours by the age of 50 had a 25% higher chance of passing away later on during the 25-year follow-up period, which may be related to a higher risk of acquiring chronic conditions that might cause mortality.
But is there a connection between chronic illness and sleeping more than is advised?
This study suggests that it may occur between the ages of 60 and 70, although possibly not before
Researchers who examined whether sleeping nine or more hours has a detrimental impact on health discovered a connection between the incidence of many illnesses in people between the ages of 60 and 70 and sleep duration.
They did not, however, discover a direct connection between more sleep in young, healthy individuals and multiple sclerosis at age 50.
The researchers found that if individuals had a chronic disease at age 50, those who slept more were 35% more likely to get another disease, possibly as a result of health issues.
Jo Whitmore, head nurse of the British Heart Foundation and a non-participant in the study, stated in a news statement.
Poor sleep can also raise blood pressure and cause inflammation, which both increase the risk of heart disease and stroke, the author continued.
"This study adds to a growing body of work that highlights the value of getting a decent night's sleep.
According to Sabia, "excellent sleep hygiene, such as a calm, dark, and pleasantly warm bedroom before bedtime" are necessary for a restful night's sleep.
"It's also a good idea to put electronics away and steer clear of heavy meals just before night. A restful night's sleep can also be aided by daytime exercise and light exposure.
