Insomnia or Sleep Disturbances Caffeine, the main stimulant in coffee, can interfere with your sleep patterns, causing difficulty falling asleep, restlessness, or disrupted sleep, especially if consumed late in the day.
Increased Anxiety or Nervousness The stimulating effects of caffeine can elevate heart rate and cause jitteriness, which may lead to feelings of anxiety, nervousness, or even panic attacks, particularly in individuals sensitive to caffeine.
Digestive Issues Black coffee is acidic and may cause stomach irritation, acid reflux, or indigestion in some people. Drinking too much may also lead to discomfort such as bloating or diarrhea.
Addiction and Withdrawal Symptoms Regular consumption of coffee can lead to dependency on caffeine, and sudden cessation can cause withdrawal symptoms like headaches, fatigue, irritability, and difficulty concentrating.
Increased Heart Rate and Blood Pressure Caffeine can temporarily raise blood pressure and heart rate, which could be problematic for individuals with hypertension or heart conditions.
Bone Health Concerns Excessive coffee consumption may interfere with calcium absorption, leading to weakened bones and an increased risk of fractures if not balanced with proper nutrition or calcium intake.
Dehydration Coffee is a diuretic, which means it increases urine production, potentially leading to dehydration if not paired with sufficient water intake.
