Excessive caffeine intake can negatively affect your heart health. While moderate caffeine consumption may be safe for most people, high amounts can lead to increased heart rate and elevated blood pressure. This can strain your cardiovascular system, especially for those with existing heart conditions. The NHS advises monitoring your caffeine intake from sources like coffee, tea, energy drinks, and certain medications. If you notice symptoms like palpitations or anxiety after consuming caffeine, consider reducing your intake. Balancing your caffeine consumption is key to maintaining a healthy heart.
