\n

For millions of people, the morning begins the same way: wake up, reach for the coffee machine, and drink the first cup before having a single glass of water.<\/p>\n\n\n\n

Coffee is often described as a diuretic, while the body naturally loses water overnight through breathing, sweating, and urine production. At the same time, heart attacks and strokes are known to occur more frequently during the morning hours.<\/p>\n\n\n\n

Put those facts together, and an alarming theory seems obvious: Does drinking coffee before water leave the blood more concentrated and increase the risk of a heart attack or stroke?<\/strong><\/p>\n\n\n\n

The reality is more complicated \u2014 and far more interesting.<\/p>\n<\/div>\n\n\n\n

Coffee does contain caffeine, which can increase urine production under certain circumstances. But moderate coffee consumption does not normally cause significant dehydration in people who regularly drink it. More importantly, the morning increase in cardiovascular events appears to be driven primarily by the body’s circadian rhythm, blood-pressure surge, sympathetic nervous system activation, platelet activity, and changes in the body’s ability to dissolve blood clots.<\/p>\n\n\n\n

So what really happens inside your body during those first hours after waking?<\/p>\n<\/div>\n\n\n
