New Delhi: The fragrant, refreshing cup of coffee first thing in the morning can make the day of many effortlessly so. According to scientists, four cups of coffee daily are safe, but too much caffeine can harm the heart. Not only can it raise the risk of high blood pressure, but also heart attack and stroke. But what is the safe limit of caffeine for the heart? A study has decoded the same, and as it turns out, there is also a safe limit for this. Anything more than 400mg of caffeine in a day can increase reading on a BP cuff and heart rate.
How does excess coffee affect the heart?
Hypertension, or high blood pressure, is a consequence of too much salt stress or caffeine intake. When suffering from this condition, it causes blood to crash against artery walls at a high pace and this can cause damage in the long run if left untreated. Researchers at Zydus Medical College in India stated that 400mg of caffeine, which is said to be the safe upper limit for caffeine, is equal to about 10 cans of soft drinks, four cups of coffee, and two energy drinks.
Data from 92 healthy participants showed that drinking too much coffee can slow down recovery after workouts. Yet, one in five of the participants exceeded the safe limit for caffeine. This could also be threatening to healthy people. Lead authors of the study found that regular intake of caffeine can trouble the parasympathetic system thereby causing high blood pressure and heart rate. Raising awareness, therefore, is a key step in raising awareness about heart health.
What are the benefits of coffee?
Coffee is a popular drink among many and for many reasons. It is a stimulant that boosts adrenaline levels and curbs cortisol as well to improve focus and alertness. Excess of it can cause anxiety, and headaches and may even make you feel sick. Experts presented the study at an American College of Cardiology conference and measured heart rate and blood pressure after a three-minute test. It was found that heavy coffee drinkers had the highest blood pressure reading after five minutes of a workout and their hearts were weaker and muscles slow in recovery. The effects were further severe in people who had 600mg of caffeine per day, which equates to six coffees.
Consequently, hypertension is also associated with several health problems like stroke, dementia, heart disease, and kidney failure. To be on the safer side, one must rely on four to five cups of coffee in a day.
