[Voice of Hope April 18, 2023](Editor: Li Wenhan) Have you ever cared regarding your sleep habits? A study from the University of Galway in Ireland found that people who slept too much or too little sleep each night, took too long naps, poor sleep quality, snoring, and sleep apnea had a higher risk of stroke than those without these sleep problems. It may be higher, but it does not mean that the two have an absolute causal relationship. It just points out their correlation and reminds the public to pay attention to their sleep conditions. Related research has been published in the American journal Neurology.

“Liberty Times” comprehensively reported that the study analyzed the data of the international case-control study “INTERSTROKE”. The average age of 4496 subjects was 62 years old, and they were divided into two groups according to whether they had stroke or not. People should answer the details of sleep behavior according to their individual conditions, including sleep length, sleep quality, nap, snoring and breathing problems during sleep, etc. Among stroke patients, 162 slept less than 5 hours, and 151 slept more than 9 hours per night; as for non-stroke patients, 43 had insufficient sleep, and 84 slept more than 9 hours per night.

The report pointed out that the research results show that a person’s sleep problems may affect the risk of stroke. Compared with people without sleep problems, people with 5 or more symptoms may have a 5-fold increased risk of stroke. In addition, those who slept less than 5 hours were three times more likely to have a stroke than those who slept an average of 7 hours; those who slept more than 9 hours were twice as likely to have a stroke as those who slept an average of 7 hours; Those who took a nap were 88% higher, but it was irrelevant if it was less than 1 hour; those who snored were 91% more likely to have a stroke than those who did not snore; patients with sleep apnea were nearly three times more likely to have a stroke than those without the disease.

Northwestern University sleep medicine experts Kristen Knutson and Phyllis Zee, who were not involved in the study, believe that the findings are consistent with previous studies. Poor sleep habits may be associated with stroke risk factors such as high blood pressure, vascular damage, and sleep disruption. Diseases and disorders may affect the body’s ability to regulate metabolism, blood pressure and inflammation. Not only that, but other studies have found that poor sleep may also be linked to diabetes, heart disease and dementia.

Similar results were found following the study adjusted for other factors that might affect stroke risk, including smoking, physical activity, depression and alcohol consumption, the report said. Study author Christine McCarthy (Christine McCarthy) said that improving sleep may have the opportunity to reduce the risk of stroke, which deserves attention. However, he also admitted that the study has its limitations, such as sleep problems provided by the subjects, and the data may not be accurate enough.

Andrew Freeman, a cardiologist at the National Jewish Medical Research Center in Colorado, who was not involved in the study, also reminded that this study can only say that there is an association between sleep problems and stroke, not a causal relationship. The focus is still on you A healthy lifestyle, good sleep habits, a healthy diet, and regular exercise can reduce the risk of stroke and cardiovascular disease.
