1. Alzheimer’s disease in 2013, researchers from Johns Hopkins University in the United States conducted a study on a group of adults aged between 53 and 91. They found that people with poor sleep every night β- Amyloid protein is deposited in a large amount, and this compound is regarded as a clear marker of Alzheimer’s disease. Therefore, lack of sleep will prevent the brain from clearing this waste, which will cause Alzheimer’s disease.
2. obesity and diabetes a study by the University of Chicago found that people who sleep only 4 hours a night contain a large amount of fatty acids in their blood, which is 15% ~ 30% higher than those who sleep 8.5 hours a night. The high content of fatty acids in the blood will affect the metabolic rate and the ability of insulin to regulate blood sugar, which will lead to obesity and diabetes.
3. Cardiovascular disease a study was read out at the annual meeting of the European Society of Cardiology in 2015. Researchers conducted a 14-year follow-up survey on 657 Russian men aged 25-64. It was found that men with sleep disorders had a 2.6-fold higher risk of myocardial infarction and a 1.5-4-fold higher risk of stroke. Nearly 2 / 3 of the patients with a history of heart attack also have sleep disorders.
4. ulcerative colitis in 2014, researchers from Massachusetts General Hospital in the United States found that ulcerative colitis and segmental enteritis may be caused by sleep problems after investigating women who participated in the “American nurse health tracking survey”. Proper sleep (6-8 hours per night) plays a necessary role in suppressing the inflammatory reaction in the digestive system (which will trigger these two types of enteritis under normal circumstances).
5. Prostate cancer according to a study published in 2013, after a seven-year follow-up survey of 2425 Icelandic men aged between 67 and 95, it was found that men who had difficulty falling asleep had a 60% increased risk of prostate cancer. The researchers attributed this association to melatonin, a hormone that regulates sleep. Melatonin can inhibit tumor growth when its level is high, but it is less in people who sleep poorly.
