A fourfold increase in stroke after drinking coffee in the morning

According to a recent study published in the journal Epidemiology, middle-aged and elderly people who drink coffee in the morning are prone to stroke, especially those who rarely drink coffee in the morning. an hour after drinking coffee in the morning, the risk of stroke is four times higher than usual. The researchers analyzed the medical records of more than 500 first-time stroke patients and found that the less coffee they drank, the more likely they were to have a stroke in the morning. People who drank less than one cup of coffee a day had a more than four-fold increased risk of stroke in the morning, while people who drank four cups of coffee a day were less likely to have a stroke. Experts believe that caffeine stimulates the nervous system, causing vasoconstriction and loss of fat deposited on the wall, blocking blood flow and causing stroke, while regular coffee drinkers may be less likely to have a stroke because they have adapted to the stimulation.
