The strange way coffee can make a night worse

Maybe you were up with your newborn every two hours, or you might have spent the night reading the company’s annual report. Or maybe you just spent the night tossing and turning around for no good reason. Anyway, if your alarm goes off at 6 a.m., you need help or you will never get through the day. You instinctively brew yourself a cup of coffee – nature’s perfect antidote to the feeling of death warmed up. However, it turns out that while your system may be jolted, it will put quite a strain on your long-term health.

A report in the British Journal of Nutrition found that a night of poor sleep followed by a cup of black coffee in the morning increased blood sugar levels by 50 percent in otherwise young and healthy study participants. One suspected reason: Caffeine may contribute to insulin resistance, says lead study author Harry Smith of the Center for Nutrition, Exercise & Metabolism at the University of Bath in the UK.

“Caffeine negatively affects sensors in our muscles that help muscles remove glucose from the blood. That’s why we saw the increased blood sugar in coffee, ”he explains.

Another solution: “Exercise is a great way to control blood sugar levels, and it is entirely possible that one morning exercise is enough to negate the effect caffeine has on blood sugar levels,” he says, noting that coffee consumption is also Moderate has been linked to other health benefits so there’s no need to get rid of the Java entirely, especially if you’re pulling an all-nighter.
