Nurse Explains What Really Raises Blood Pressure, Debunks ‘Too Much Thinking’ Claim

A Nigerian nurse has challenged the widely held belief that “thinking too much” directly causes high blood pressure, describing the claim as a misconception.

The nurse made the clarification in a video circulating on social media, where she addressed a common explanation often given to people diagnosed with hypertension.

“Nigerians, too much thinking does not cause high blood pressure,” she said.

According to her, thinking takes place in the brain, while hypertension primarily involves the cardiovascular system, including the heart and blood vessels.

“You think with your brain. It is your brain you are using to think,” she said.

She explained that the frontal lobe of the brain is involved in thinking, while high blood pressure concerns pressure within the blood vessels and the work of the cardiovascular system.

Family History Can Increase the Risk

The nurse identified genetics and family history among the factors that can increase a person's risk of developing hypertension.

She stressed, however, that having a family member with high blood pressure does not mean a person will necessarily develop the condition.

“If you have a family member that is hypertensive, I’m not saying you must have it though. It puts you at a risk of having it,” she said.

Family history is one of several recognised risk factors for hypertension.

Too Much Salt May Raise Blood Pressure

The nurse also warned about excessive salt consumption, advising people to be careful about the amount of salt and seasoning added to their meals.

“Too much salt can lead to high blood pressure,” she said.

High sodium intake can contribute to increased blood pressure, particularly in people who are sensitive to sodium.

Physical Inactivity Is Another Risk Factor

The nurse further urged people to become more physically active, particularly those who spend long periods sitting or lying down.

She criticised lifestyles in which people spend much of their day on their phones and social media without making time for physical activity.

“You cannot even stand up and say, let me just walk around more. Let me just take a stroll,” she said.

Regular physical activity is widely recommended as part of a healthy lifestyle and can help with blood-pressure control.

Overweight and Obesity

Being overweight or obese was another factor identified by the nurse.

“When somebody is too fat or when somebody is overweight, it can lead to high blood pressure,” she said.

Excess body weight is associated with a higher risk of hypertension, making weight management an important part of cardiovascular health.

Smoking and Excessive Alcohol

The nurse also identified smoking and excessive alcohol consumption as factors associated with high blood pressure.

“Smoking, it can cause high blood pressure,” she said.

On alcohol consumption, she added: “Excessive alcohol consumption can lead to high blood pressure.”

Both tobacco use and heavy alcohol consumption are recognised cardiovascular risk factors.

Age Also Matters

The nurse noted that increasing age can also raise the likelihood of developing hypertension.

As people grow older, changes in the arteries and other cardiovascular processes can contribute to increased blood pressure.

What About Stress and Worry?

While the nurse rejected the idea that excessive thinking itself should be described as a direct cause of hypertension, she also discussed chronic stress and inadequate rest.

She referred to people who work continuously without taking sufficient time to rest as examples of individuals who may experience chronic stress.

“Chronic stress, those of you that don’t use to rest,” she said.

The distinction is important.

Stress can cause a temporary increase in blood pressure, and repeated or prolonged stress may contribute to unhealthy behaviours or other factors associated with cardiovascular risk. However, the relationship between psychological stress and the development of chronic hypertension is more complicated than simply saying that “thinking too much” causes high blood pressure.

The nurse ultimately maintained that excessive thinking should not be presented as a straightforward explanation for hypertension.

“There are still more, but I promise you excessive thinking does not cause high blood pressure. Stop having that misconception,” she said.

Key Factors Associated With High Blood Pressure

The discussion highlights several established risk factors associated with hypertension, including:

Family history and genetics

High sodium intake

Physical inactivity

Overweight and obesity

Smoking and tobacco use

Excessive alcohol consumption

Increasing age

Certain aspects of long-term stress and lifestyle

However, hypertension does not always have an obvious single cause. A person's blood pressure can be influenced by a combination of genetic, biological, dietary and lifestyle factors.

People should therefore avoid assuming that high blood pressure is simply the result of worrying or thinking excessively.

Regular blood-pressure checks can help identify hypertension, particularly because the condition may not produce noticeable symptoms in many people.

Anyone with persistently elevated blood pressure readings should discuss them with a qualified healthcare professional rather than relying on assumptions about the cause.
