How Stressful Jobs Increase the Risk of Hypertension

Medical experts have warned that individuals who consistently work in high-stress or adrenaline-driven environments face a greater risk of developing hypertension, anxiety, and sleep disorders if such conditions are not properly managed.

They explained that people in fast-paced professions—such as emergency medical staff, trauma responders, journalists, and security personnel—are particularly vulnerable due to their constant exposure to stress and crisis situations.

Experts noted that while adrenaline levels usually drop once a stressful event ends, repeated exposure to high-pressure situations keeps stress hormones like adrenaline and cortisol elevated, leading to persistently high blood pressure and cardiovascular strain over time.

According to Mental Health America, adrenaline, or epinephrine, is a hormone produced by the adrenal glands in response to excitement or danger. It prepares the body for “fight or flight” by increasing heart rate, expanding airways, and improving blood flow to muscles. However, prolonged or frequent surges can negatively affect heart health.

The World Health Organisation defines hypertension as sustained blood pressure readings of 140/90 mmHg or higher. It identifies the condition as a leading cause of death globally, with more than 1.4 million adults aged 30–79 diagnosed in 2024.

A professor of medicine at the College of Medicine, University of Lagos, Idi-Araba, Olufemi Fasanmade, explained that individuals in demanding professions often record higher blood pressure and blood sugar levels, experience poor sleep, and endure continuous heart strain.

“When this persists without sufficient rest or recovery, it can result in hypertension, diabetes, obesity, poor sleep quality, and mental health issues such as anxiety or post-traumatic stress disorder,” he said.

He advised that prevention should focus on self-care, including regular rest, exercise, adequate sleep, and mental health support. “If stress occurs continuously without downtime, it eventually takes a toll on the body,” he warned.

Fasanmade also observed that some professionals become psychologically attached to constant pressure, finding it difficult to relax outside work. “Some people actually get addicted to high-pressure jobs and feel unfulfilled when away from them. That’s not a healthy pattern. Taking breaks, exercising, and seeking therapy when necessary are essential,” he added.

He encouraged those in stressful roles to take frequent holidays, include short breaks during shifts, and engage in relaxing activities such as reading or watching TV. In some cases, he said, therapy may be necessary to manage chronic stress.

He further advised workers in such roles to watch for warning signs like fatigue, anxiety, sleep disturbance, or rising blood pressure, noting that these are indicators the body needs recovery. “If blood pressure readings rise steadily over time, it’s a signal to rest and undergo medical evaluation,” he said.

Similarly, the President of the Nigerian Hypertension Society, Professor Simeon Isezuo, said hypertension affects one in three adults in Nigeria. While genetics play a role, he emphasised that lifestyle factors—especially stress and high salt consumption—are major contributors.

He added that individuals with underlying risk factors who work in high-pressure environments are more likely to develop hypertension, while those already diagnosed may find it harder to keep their blood pressure under control.
