7 + 1 sources of stress affecting seafarer wellbeing

Life at sea can expose seafarers to multiple pressures at the same time, from demanding workloads and financial concerns to isolation, disrupted sleep and global uncertainty.

Stress does not always have one obvious cause. Work demands, family separation, difficult relationships, environmental conditions and physical exhaustion can build up simultaneously, particularly when there is limited time for recovery or support.

Recognising the source of stress—and noticing its early warning signs—can help seafarers respond before it affects their physical health, emotional wellbeing, concentration and ability to work safely.

Stress rarely occurs in isolation

For seafarers, the pressures of work and personal life are often closely connected. Long periods away from home, demanding schedules, limited privacy, interrupted sleep and concern for family members can combine, making it difficult to identify one specific source of distress.

ISWAN’s SeafarerHelp 2025 Annual Review highlighted this cumulative effect. Seafarers increasingly sought support for complex, interconnected challenges involving their wellbeing, relationships, finances, employment and safety.

Mental health-related contacts increased by 35.9% compared with the previous year, reaching the highest level recorded by the helpline.

The following seven categories are not separate medical diagnoses. Instead, they provide a practical framework for recognising common sources of stress and understanding how overwhelm may appear.

#1 Occupational stress

Occupational stress can result from heavy workloads, tight deadlines, long or irregular working hours, demanding tasks, understaffing and limited control over how work is organised.

On board, these pressures may be intensified by inspections, port calls, changing operational demands, administrative responsibilities and insufficient recovery time between tasks.

The World Health Organization identifies excessive workloads, long or inflexible hours, job insecurity, limited support and unsafe working conditions as psychosocial risks that may affect mental health at work.

Common signs include reduced concentration, irritability, mistakes, declining motivation and a persistent feeling of being under pressure.

#2 Financial stress

Financial stress may be linked to debt, family expenses, irregular income, gaps between contracts, job insecurity or concerns about future employment.

Seafarers may also feel responsible for supporting extended family members or maintaining a particular standard of living ashore. ISWAN’s latest findings indicate that financial concerns frequently interact with family relationships, employment problems and mental health difficulties.

Warning signs may include persistent worry, disrupted sleep, avoiding financial decisions, frequently checking accounts and being unable to relax, even when no immediate action is required.

#3 Emotional stress

Emotional stress can arise from grief, relationship difficulties, conflict, family separation or the effort involved in hiding and managing difficult feelings.

Some seafarers may feel pressure to appear resilient or avoid discussing personal problems because they do not want to worry their families or be perceived as unable to cope. However, continually suppressing emotions may contribute to exhaustion and withdrawal.

Signs may include sudden mood changes, sadness, anger, emotional numbness, increased sensitivity, reduced patience and a loss of interest in activities or conversations that would normally be enjoyable.

#4 Environmental stress

Environmental conditions can affect both physical comfort and mental wellbeing. Noise, vibration, heat, poor lighting, confined spaces, disrupted routines and constant screen exposure may prevent the body and mind from properly switching off.

Living and working in the same environment can make recovery particularly difficult for seafarers. Unlike shore-based workers, they may not be able to leave the workplace after their shift or find a quiet space away from operational activity.

Environmental stress may also be linked to eco-anxiety – distress associated with climate change, extreme weather, environmental degradation and uncertainty about the planet’s future. For seafarers, who directly experience changing weather and ocean conditions, these concerns may feel particularly immediate.

Possible signs of environmental stress include headaches, muscle tension, restlessness, irritability, poor sleep, emotional distress and a persistent sense of overstimulation.

#5 Psychological stress

Psychological stress often develops through internal pressure. Perfectionism, fear of failure, imposter syndrome, overthinking and decision fatigue can make even routine responsibilities feel overwhelming.

Seafarers working in safety-critical roles may place extremely high expectations on themselves because mistakes can have serious consequences. While responsibility and attention to detail are essential, believing that every decision must be perfect can contribute to hesitation, self-doubt and mental exhaustion.

Signs may include procrastination, negative thinking, difficulty making decisions, repeatedly questioning completed work and feeling that personal performance is never good enough.

#6 Social stress

Social stress may arise from loneliness, isolation, conflict, lack of support, social comparison or people-pleasing.

A vessel is both a workplace and a temporary home. Difficult relationships cannot always be avoided, while differences in culture, rank, communication style and personality can create additional tension. At the same time, maintaining relationships ashore may become challenging because of time differences, limited connectivity and long periods of absence.

Possible signs include withdrawing from others, feeling disconnected, agreeing to more than can realistically be managed, resentment and excessive concern about what other people think.

#7 Physical stress

Physical stress occurs when the body does not receive enough rest, nourishment or recovery. It may result from sleep deprivation, illness, dehydration, poor nutrition, overexertion or demanding shift patterns.

Seafarers face challenges including long periods away from home, adverse weather and living and working in the same environment. Prolonged stress and fatigue may negatively affect health, making it important to recognise and manage both at an early stage.

Signs include persistent fatigue, reduced energy, muscle tension, appetite changes, frequent illness, poor coordination and slower reactions. These symptoms should not simply be accepted as unavoidable parts of working at sea.

The “+1” stressor: Geopolitical anxiety

Geopolitical anxiety is a useful term for stress and worry associated with armed conflict, political instability, humanitarian emergencies, maritime security threats and uncertainty about global events.

It is not a separate clinical diagnosis, but it describes a growing source of emotional pressure.

For seafarers, geopolitical events may have immediate personal and operational consequences. They may be required to sail through or close to high-risk areas, experience voyage changes, face delayed crew changes or worry about whether they will return home safely.

Others may have family members living in affected regions or feel powerless while following events from thousands of miles away.

Ongoing exposure to distressing news, graphic images and uncertainty may contribute to anxiety, sadness, anger, helplessness and emotional fatigue, even when someone is not directly involved in the crisis.

Those with personal, family or cultural connections to affected areas may experience stronger reactions.

Possible signs of geopolitical anxiety include:

• Constantly checking news and social media
• Feeling unusually alert or unable to relax
• Imagining worst-case scenarios
• Difficulty sleeping or concentrating
• Irritability, anger or emotional numbness
• Feeling helpless about events beyond personal control

Five ways to prevent stress from becoming overwhelming

1. Recognise your personal warning signs. Stress may first appear through changes in sleep, appetite, concentration, mood or behaviour. Early recognition makes it easier to respond.
2. Set boundaries around news exposure. Stay informed through reliable sources, but avoid monitoring developments continuously. Consider checking the news at specific times and muting accounts that regularly share graphic or sensational content.
3. Protect basic routines. Prioritise sleep, regular meals, hydration and appropriate physical activity wherever operational conditions allow. Even small routines can provide stability during uncertain periods.
4. Focus on what you can control. It may not be possible to resolve a global crisis, change a voyage plan or remove every workplace pressure. Focus instead on immediate actions, such as following safety procedures, discussing concerns and taking proper rest.
5. Stay connected. Speak with trusted crewmates, family members, friends or welfare professionals. Social support can reduce isolation and help place stressful thoughts in perspective.

To remind, CHIRP Maritime has recently published guidance for seafarers who find themselves around uncertainty and high-risk situations, like operating in areas of conflict.

When to seek additional support

Professional support should be considered when stress, anxiety, sadness or anger becomes persistent and begins to interfere with sleep, work, relationships or routine tasks.

Other warning signs include panic, hopelessness, emotional numbness, intense distress related to news exposure or feeling unable to cope safely.

Seeking assistance is not a sign of weakness or professional failure. It is an important step in protecting personal wellbeing and onboard safety.
