14. You have serious eye pressure.
That intraocular pressure you’re experiencing could have started with that extra cup of coffee you downed this morning. Caffeine can increase your blood pressure, thus increasing pressure in the eyes and putting you at risk for glaucoma over time. Worse yet, if left untreated, this can even lead to irrevocable vision damage or even blindness.
15. Your bones break easily.
Nearly 54 million Americans have low bone density or osteoporosis, meaning they’re more susceptible to potentially-debilitating falls and broken bones. Unfortunately, those extra cups of coffee could be putting you at risk: in fact, researchers at Creighton University have discovered that caffeine intake is significantly correlated with bone loss in older women.
16. Your teeth are discolored.
If you’re feeling less than pleased with your smile, you might want to start thinking about limiting your coffee consumption. The acids in coffee can contribute to decreased mineralization in teeth, leading to enamel erosion over time. Coupled with coffee’s staining effect, you’ve got a recipe for some not-so-pearly whites.
17. You can’t sleep.
Anyone who’s ever found themselves tossing and turning after having a cup of coffee too close to bedtime won’t be surprised to discover that insomnia and over-consumption of coffee go hand-in-hand. “If you’re having trouble falling asleep, try laying off coffee by 1:00 p.m. to ensure the caffeine has been metabolized by bedtime. Also, skip the night time cup of green tea and piece of chocolate as these too contain caffeine, while smaller doses, but can still affect sleep,” suggests Hundt.
