#127 Controlling Hypertension at Sea

-

Life at sea is demanding — long hours, high stress, unpredictable weather, and limited access to healthcare can make managing chronic conditions like hypertension (high blood pressure) a major challenge. Yet, keeping your blood pressure under control is crucial for your health, safety, and ability to perform effectively onboard.

Here’s a practical guide to help seafarers monitor and manage hypertension while at sea



Understanding Hypertension

Hypertension is when your blood pressure consistently stays above normal levels (usually 140/90 mmHg or higher). Left unchecked, it can lead to serious issues such as heart disease, stroke, or kidney problems — all of which are especially risky in remote maritime environments.

Why Seafarers Are at Risk
Several factors common in the maritime lifestyle can contribute to high blood pressure:

  • Irregular sleep patterns due to shift work

  • High-sodium diets from preserved or processed food

  • Lack of physical activity in confined spaces

  • Stress and isolation from long periods away from home

Smoking and alcohol use as coping mechanisms

Tips to Control Hypertension at Sea

1. Regular Monitoring

Keep a digital blood pressure monitor onboard. Track your BP readings at the same time each day and log them. Early detection can prevent complications.

2. Medication Compliance

Always bring an adequate supply of prescribed medication for the entire voyage, plus extra for emergencies. Set reminders or pair it with daily routines to ensure you never miss a dose.

3. Adopt a Heart-Healthy Diet

  • Limit salty, fatty, and processed foods.

  • Incorporate more fruits (like apples, bananas) and vegetables if available.

  • Choose lean proteins like fish and chicken over red meats.

4. Exercise Onboard

Even in tight spaces, regular movement helps:

  • 15–30 minutes of walking, stretching, or body-weight exercises daily

  • Simple routines like squats, push-ups, or using resistance bands

5. Manage Stress

  • Practice deep breathing, meditation, or mindfulness techniques

  • Stay connected with family via calls or messages

  • Engage in hobbies (reading, music, journaling)

6. Limit Stimulants

Cut back on caffeine, smoking, and alcohol — all of which can spike your blood pressure.

Emergency Readiness
Inform the ship’s medical officer about your condition and ensure your crewmates are aware of how to assist in case of a hypertensive emergency. Keep your medical documents and prescriptions easily accessible.

Final Thoughts
Hypertension doesn’t have to anchor your health. With awareness, planning, and discipline, seafarers can control high blood pressure and lead a strong, steady life at sea.

Your health is your lifeline — protect it, even in the middle of the ocean.

 Differences between IT and OT systems Whereas IT systems manage data and support business functions, OT is the hardware and software that directly monitors/controls physical devices and processes and as such are an integral part of the ship and must function independently of the IT systems onboard. The systems can, however, be connected to the IT network for performance monitoring, remote support etc. Such systems are sometimes referred to as belonging to the Industrial Internet of Things (IIOT). There may be important differences between who handles the purchase and management of the OT systems versus IT systems on a ship. IT managers are not usually involved in the purchase of OT systems and may or may not have a thorough understanding of cyber security. The purchase of such systems should involve someone, who knows about the impact on the onboard systems but will most probably only have limited knowledge of software and cyber risk management. IT covers the...
