May 2nd, 2016 – New Study: A Week Of Inadequate Sleep Linked With Heart Attack & Stroke

According to a study published in the journal, Scientific Reports, just a week of inadequate sleep Ukcan damage the heart due to a rise in ‘bad’ cholesterol.

The researchers showed that people who spent too few hours in bed also had less ‘good’ cholesterol circulating in their blood, than those who slept sufficiently. Seven to eight hours of sleep for adults was recommended by the National Sleep Foundation (NSF), the body dedicated to improving health and well-being through sleep education and advocacy.

A PhD student in sleep research at the University of Helsinki, Vilma Aho, said based on the outcome of this study, people should be educated on the importance of getting the right amount of rest to prevent common diseases, as well as eating healthily and exercising.

Genes, which regulate the transport of cholesterol around the body are less active in sleep deprived people than those getting a good night’s rest, the researchers found. However, the findings could explain why those who get less than the recommended seven to eight hours sleep a night were at higher risk of cardiovascular diseases such as heart disease, heart attacks and strokes.

Cholesterol is a kind of fat made by the liver and found in the blood, which is essential to the body as cells and organs need it. But there are two types; ‘good’ high-density lipoproteins or HDL, and ‘bad’ or low-density lipoproteins.

‘Bad cholesterol’ can damage the walls of the arteries, causing them to become hardened, scarred and plaques form. These plaques can restrict blood flow to the heart, causing a heart attack, or can break off and travel to the brain, causing a stroke. Good cholesterol, on the other hand, acts as a magnet, hoovering up the bad cholesterol and moving it out of the arteries and into tissues such as the liver, or to make hormones.

The team, from the University of Helsinki in Finland, wanted to find out why lack of sleep was linked with more heart problems and strokes.

According to report in the mailonline, the researchers analysed people sleeping in a laboratory, and looked at data on sleep levels and disease in members of the general population. Similarly, they looked at the impact of sleep deprivation on how genes regulating the transport of cholesterol around the body – and on the actual levels of cholesterol in the blood.

    Very instructive. Unfortunately it is becoming increasingly difficult for an average adult male to enjoy an eight hours sleep in the recent time.

    This is well know fact that sleeplessness has big impact on regenerative body system,it leads to insomnia and other psychological impairments but my people due to lack of knowledge and inconsiderate attitude toward others choose to continue in denial and further cause unimaginable damage to people’s health with their incessant noise making, this is why the government have to take a hard stand on the noise makers both the religious and the others such as traders and traffic noise;sometime you hear someone die suddenly without any obvious signs, that is because they have being suffering in silence because of daily pressures of survival and couple with overzealous religious conviction -‘it is not my potion’ mentality. it is about time this information is made available to those that are the main causes of the menace of noise pollution in our society, so that they can see the effect of their action on the nation,because generations are being inadvertently destroyed due to exposure to high level of noise. your hearing can be impaired which the lead to having to shout in instead of speaking normally (anti social behavior) because you can’t gauge level of sound properly, sleeplessness also lead to instability of the mind which contribute to irrational behavior, the list is endless. i personally have been on the receiving end of the impact of sleep deprivation. My 93 dad was constantly deprived of sleep by the ‘church’ next door, i brought him to stay with me in my house so that he can have more care and that his medications can be administered properly, but the incessant noise making from the ‘church’ next door made it impossible for him to rest so that the medication can’t take effect, screaming and shouting into the loud speakers day and night; i spoke to the ‘pastor’ regarding this noise but was met with arrogance and rebuffed,such is the mentality of Nigerians so deluded and misguided.Sadly my dad has passed away, the doctor concluded that sleep deprivation is contributory factor because the medication were not giving chance to work, i hope that Nigerians will learn to respect other people’s right to live in dignity and enjoyment of privacy in their own homes as guaranteed in the constitution.
