Effects of Stress on Physical Health - Essential Hypertension

Hypertension is a condition of persistently high blood pressure in the arteries. It is very common in modern life, especially in people above 40–45 years. It is a major cause of strokes and cardiovascular diseases, which can lead to death.

• The heart is highly sensitive to emotional stress such as worry, fear, anger, and tension.
• During stress, blood vessels in many internal organs constrict, and more blood is sent to the muscles.
• Because many small vessels are narrowed, the heart must pump harder, which raises blood pressure.
• If stress is long-lasting, blood pressure can remain high continuously, leading to strokes and other heart diseases.

• Hypertension is closely related to kidney function.
• When kidneys receive less blood due to vessel constriction, they release a substance called renin.
• Renin further raises blood pressure and can help maintain hypertension.
• This can create a harmful cycle leading to kidney damage or kidney failure.

• Many people with high blood pressure have no clear warning signs.
• Some may feel tiredness, headache, or dizziness, but these symptoms are not always present.
• Because it can remain hidden, hypertension is dangerous and often called a “silent” condition.

• Besides biological causes, severe emotional stress can arouse or maintain chronic hypertension.
• High blood pressure is more often found in urban areas and places undergoing rapid cultural or socio-economic change.
• Such environments create high levels of stress, which increase the risk of developing hypertension.

• Hypertension is viewed as a psychosomatic disorder influenced by psychological factors.
• According to psychoanalytic views, hypertensive individuals use psychological defences less effectively.
• They have few healthy outlets for aggressive impulses such as anger and hostility.
• Their blocked aggression is expressed indirectly through bodily symptoms, especially persistently high blood pressure.

• Meaning: Hypertension is persistently high blood pressure, common after 40–45 years, and a major cause of strokes and heart diseases.
• Emotional Stress: Stress causes blood vessels to narrow, making the heart work harder and increasing blood pressure.
• Kidneys & Renin: Reduced blood flow to the kidneys releases renin, which further raises blood pressure and may damage the kidneys.
• Silent Nature: Hypertension often shows no clear symptoms; sometimes headache, tiredness, or dizziness occur.
• Psychological Factors: Chronic stress and blocked emotions (such as anger) can contribute to high blood pressure, especially in stressful urban environments.
