University of California, San Francisco study - Women who get less than six hours of sleep every night are at a greater risk of inflammation and thus heart attacks
Singapore: A new study by University of California, San Francisco, US, (UCSF) has revealed that women who get less than six hours of sleep every night are at a greater risk of heart attack. The results regarding the study are published in the Journal of Psychiatric.
The study pointed out that poor sleep or waking up too early, can lead to rise in the levels of inflammation among women with coronary heart disease. Researchers found that while inflammation affected women, it did not affect men, even after things such as lifestyle and demographics were taken into account.
This five-year study, which involved nearly 700 participants, began in 2000 with 66 men and 64 women. The results of the study show that women reported very poor or fairly poor sleep quality at 2.5 times the level of inflammation as men did, who said they slept very poorly.
Dr Aric Prather, lead author of the study and assistant professor of psychiatry, University of California, San Francisco, said that, "Inflammation is a well-known predictor of cardiovascular health. Now we have evidence that poor sleep appears to play a bigger role than we had previously thought in driving long-term increases in inflammation levels and may contribute to the negative consequences often associated with poor sleep."
