Sleep Deprivation May Lead to Dementia
To increase the level of oxygen in your bloodstream, get plenty of fiber in your diet and eat fruits and vegetables that are rich in potassium, magnesium, and vitamin C
Time and time again experts have warned us about the habits that can interfere with your quality of sleep, including eating dinner too late, watching TV before bedtime, or staying on your laptop or cellphone while you’re in bed. Most people ignore these factors, however, and the changes in your biological clock could have serious consequences.
Sleep deprivation and sleep disorders can affect your physical and mental health. In addition to this, a recent study found that not getting enough sleep and other health problems could cause brain abnormalities to develop that are similar to what patients with dementia experience.
This finding was made by a group of researchers at the Veterans Administration in Hawaii, which collected data from 167 men with an average age of 84 years and who were followed until their deaths, on average for six years. Post-mortem autopsies focused on the brain, searching for minor aneurisms or changes in the cerebral tissue that occur more often in people who have poor sleeping habits due to factors like sleep apnea or emphysema.
The study found that individuals who had experienced changes in their cerebral tissue also had low levels of oxygen in the blood, something that’s related to the onset of dementia.
Low levels of oxygen associated with brain abnormalitiesThe results were based on the fact that brain abnormalities are often found in people who have problems sleeping as well as low levels of oxygen in the bloodstream.
In their final analysis, the researchers found that patients who spent between 77% and 99% of their sleep cycle with low levels of oxygen in their bloodstream were up to four times more likely to develop brain damage. They concluded that people with low levels of oxygen in their blood while they sleep are more likely to experience brain abnormalities similar to dementia.
The study’s lead investigator, Dr. Rebecca P. Gelber of the Pacific Islands VA Health Care System and the Institute for Pacific Health Research and Education in Honolulu, Hawaii, said that their findings showed that low levels of oxygen in the blood and sleep problems can contribute to brain damage and dementia.
While she acknowledges that more research is needed to link sleep problems with dementia, the results are very interesting, particularly when you consider the fact that the number of people with sleep disorders has increased in recent years.
Their study was published in the medical journal The American Academy of Neurology, titled “Association of Brain Lesions at Autopsy with Polysomnography before Death,” and it includes important information about the duration of sleep time, oxygen saturation of the blood, and the presence of sleep apnea.
What causes low levels of oxygen in the bloodstream?According to the experts, low levels of oxygen in the blood can be caused by the following factors:
- Chronic obstructive pulmonary disease (COPD)
- Anemia with acute respiratory distress syndrome (ARDS)
- Pulmonary fibrosis
- Congenital heart disease
How can you increase levels of oxygen in the blood?To increase your levels of blood oxygen you should follow a diet that’s high in fiber, along with a healthy amount of fruits and vegetables that are rich in potassium, magnesium, and vitamin C. Among the best options are:
- Celery and parsley
- Citrus fruits
- Green apples
It’s also important that you reduce your sodium intake, avoid eating fats, sugars, and processed foods. You should also listen to doctors’ recommendations about sleep problems, which can also affect your brain and have other negative impacts including a bad mood, fatigue, difficulty concentrating, stress, and more.
