Severe hypertension: potential harm from coffee

Severe hypertension: potential harm from coffee.


A Japanese study observed over six thousand men and twelve thousand women for almost twenty years. It has been found that those who have severe hypertension and drink more cups of coffee a day double the risk of death from cardiovascular causes. Those with non-severe hypertension, on the other hand, don’t. Severe hypertension is defined as blood pressure above 160/100 mmHg. If you consume green tea or a cup of coffee daily, then there is no increased risk. 


Other previous studies have shown that drinking coffee regularly can reduce the risk of developing diseases such as type 2 diabetes, cancer and depression. If we drink too much it can lead to an increase in blood pressure leading to anxiety, heart palpitations and sleep disturbances. During the twenty – year study , 842 deaths from cardiovascular disease were recorded.

Drinking more cups of coffee per day was a doubling of the risk of death for a blood pressure equal to or higher than 160/100 mm Hg. Furthermore, it was found that those who consumed coffee more frequently were young people, smokers and drinkers and consumed fewer vegetables. They had higher cholesterol, regardless of blood pressure. In short, as with any food or drink there are pros and cons. It is therefore important to know the negative and positive aspects of everything we take in through our diet.
