Bad news for sleep lovers: long sleep provokes cancer and dementia

(ORDO NEWS) — One more thing has been added to the consequences of sleep for human health. Until now, there has been a lot of talk about the dangers of sleep deprivation, while a recent study in Japan showed that excessive sleep is also harmful, as it increases the risk of cancer.

One of the most researched topics is the impact of sleep on human health. While studies have been published over the years about the negative effects of lack of sleep on the body, a recent study in Japan found that too much sleep increases the risk of cancer. A group of researchers working on cancer prevention strategies in Japan found that sleeping 10 hours or more a night increased a woman’s risk of developing cancer by 19%.

The study also found that men and women who slept more than ten hours also had an increased risk of dying from cancer. Spending most of the day in bed provokes many diseases, primarily cancer, but lack of sleep is also very unhealthy. Research on the impact of sleep on human health was commented on by professor at Uskudar University, a specialist in radiology, Dr. Güner Sönmez.

If you don’t get enough sleep, this happens in your body

Speaking about how both too little and too much sleep negatively affects metabolism, Prof. Dr. Sungmez said, “There are a lot of studies on this. They all mostly agree that it is good to get at least 6.5 hours and no more than nine hours a day. So here, as in everything else, you also need to observe the measure. Try to sleep 7-7.5 hours a day.”

According to the expert, lack of sleep primarily destroys and undermines the immune system. “Lack of sleep weakens the immune system,” continued Prof. Sonmez. “It makes our body vulnerable to viral diseases, hypertension, obesity, diabetes, some types of cancer, and also sets the stage for these diseases. It triples the risk of contracting the flu.

Creates similar risks and for other viral diseases Halving the effectiveness of the flu shot How does all this happen Under normal conditions, our blood has killer cells and some special lymphocytes that fight foreign substances and cancer coming in from the outside Research shows that just one day of insomnia reduces the number of these cells by 70% and increases the risk of cancer in the long term by almost 40%.”

Insomnia steals life

Good enough sleep also protects the cardiovascular system, Sönmez noted. He continued, “According to a study published in the American Journal Of Cardiology, long-term sleep deprivation doubles to triple the buildup of plaque in the arteries of the heart.

Those who sleep less than six hours a night have a 20% higher risk of having a heart attack.” than for those who sleep six to nine hours.For those who sleep five hours, this risk is 52% higher than for those who sleep seven to eight hours.Lack of sleep affects both our eating habits and metabolism, which makes us fatter. Sleeping less than 7.5 hours a night promotes hypertension, insulin resistance, and then diabetes.  It takes you 10-12 years of life.”

Good sleep preserves memory

Prof. Dr. Güner Sönmez said that there are studies showing a close relationship between sleep and metabolism, as well as between sleep duration and the development of dementia. “Lack of sleep increases the risk of developing Alzheimer’s disease.

According to a Boston University study, middle-aged people who sleep six hours or less a night are 30% more likely to develop dementia later in life than those who sleep seven hours. When we fall asleep, the circulation of cerebrospinal fluid in the brain increases. Thanks to this, the brain is practically washed out, restored, developed, protected from the accumulation of harmful proteins,” the expert added.

For quality sleep…

  • Physical exercise for half an hour three to four hours before bedtime is beneficial.
  • Go to bed at the same time every day.
  • The bedroom should be cool and dark.
  • Do not smoke or drink alcohol.
  • If you drink coffee, then do it at least six to eight hours before bedtime.
