Sleep patterns in middle-aged women can increase the risk of stroke, according to a study conducted in the United States. Increased risk of stroke (around 70%) are associated with women who slept for 9 hours or more in the evening, according to a report in the medical journal Stroke.
Link between sleep and death have long been studied in various studies, but evidence of an association between sleep patterns and cardiovascular disease is very little, says Dr. Chen Jiu-Chiuan of North Carolina at Chapel Hill.
Recent research conducted involving 93 175 women aged 50-79 years. Overall, 8.3% reported waiting a they normally slept no more than 5 hours per night while 4.6% reported that they were at least 9 hours of sleep at night.
After following the group for 7.5 years, the researchers found that 1,166 women experienced an ischemic stroke, type of stroke, which is often the case that arises when a blood vessel in the brain is blocked. This prevents oxygen from reaching the brain and causes the death of brain cells.
The analysis can be taken by Dr. Chen and his team is that women who sleep at night with a duration of 6 hours or less, 8 hours, and 9 hours or more may increase the risk of stroke by 14%, 24%, and 70%, respectively.
The side effects of sleeping 6 hours or less were more pronounced in women who have an increased risk of cardiovascular disease at the beginning of the study. In this group, the number of hours of sleep increased their risk of stroke by 22%.
Further analysis also suggested that the side effects of long periods of sleep is not related to the frequency of snoring or sleepiness. Therefore, sleep patterns that are too long or too short of a normal can be an independent risk factor for stroke.
Chen added, "The data does not mean that we get to make women who have longer hours of sleep a night to cut their sleep time so that they have a lower risk of disease. Further research is needed to help understand the mechanisms involved in the research that we do. "
