Health anxiety among seafarers is emerging as a critical but under-recognised threat to crew wellbeing, with maritime health specialists warning the condition is being routinely overlooked across the industry.

While awareness of mental health at sea has improved in recent years, experts say a key component, health anxiety, is still slipping under the radar, despite its potential to escalate into a serious psychological disorder if left unaddressed.

With the recent political tensions in the Middle East, safety is currently a key concern for seafarers and mental health experts are warning that the industry could see a rise in health anxiety cases amid the escalating conflict.

Life onboard ships continues to expose crews to prolonged confinement, security risks isolation, and limited external stimulation. In these conditions, seafarers are more likely to focus inward, with even minor physical symptoms becoming amplified over time. What may begin as mild concern can quickly evolve into persistent and debilitating anxiety, says Mental Health Support Solutions (MHSS), member of OneCare Group.

“Health anxiety is far more than overthinking – it is a genuine clinical condition,” said Charles Watkins, Director of Clinical Operations at MHSS. “When it is dismissed, not only are individuals invalidated, but their symptoms are likely to worsen.”

Industry stakeholders, including shipowners and managers, are now being urged to take a more proactive stance. Experts stress that early intervention—through awareness, training, and access to support—can significantly reduce the impact on crew.

“Preparation is key. When seafarers understand that these reactions are common, they are far more likely to seek help before the situation escalates,” Charles added.  “We are seeing seafarers more exhibit signs of anxiety and with recent tensions in the Middle East, they are rightfully scared for their safety. These feelings will only add to health anxiety,”

Practical, onboard strategies are also being highlighted as part of the solution. Encouraging crew to delay repetitive symptom checking, limit excessive online searches, and speak openly with colleagues can help break cycles of anxiety and reduce escalation.

The warning comes amid growing scrutiny of seafarer welfare standards, with calls for a more nuanced understanding of the psychological pressures unique to life at sea.

“To support seafarers effectively, the industry must first recognise the distinct challenges they face and respond with targeted, informed action,” Charles said.

Experts warn that health anxiety does not remain purely psychological, but can also manifest in physical symptoms if left unaddressed.

“Over time, sustained stress of this kind can have wider effects, including impacts on immune function, worsening autoimmune-related conditions and even cardiovascular events in some cases,” concluded Dr Jens, CEO and Founder of Marine Medical Solutions, member of OneCare Group.
