The emotional cost of animal research

Animal research can place emotional demands on the people who conduct it and write about it. Support for researchers includes recognising distress, providing practical help and considering how research methods affect the people using them.

Moral distress and compassion fatigue

The tension between scientific aims and animal welfare can lead to moral distress: euthanasia, invasive procedures and witnessing suffering can provoke guilt, sadness and anxiety that affect research and writing. ¹ Unaddressed emotional burdens can contribute to prolonged stress, burnout and other mental health problems. ¹

Compassion fatigue is a form of secondary traumatic stress in which repeated exposure to distressing situations can lead to emotional exhaustion and diminished empathy. ¹ In animal research, caring for animals before or after painful procedures and repeatedly encountering suffering and death can erode emotional resilience. ¹ Consequences can extend to personal relationships, job satisfaction, productivity, staff retention and the quality of animal care. ¹

Researchers’ responses differ. ² One scientist recalled colleagues during her master’s and doctoral studies who were visibly unhappy about animal work, wished alternatives were available or wanted their principal investigators to try new methods. ² Some appeared untroubled and later led animal-research laboratories, while others decided to work exclusively with human samples after graduating. ² In her experience, most disliked euthanising mice, and principal investigators often overlooked the effect on their teams’ wellbeing and enjoyment of research. ²

Institutional and supervisory support

Mental health support should be available to people who euthanise research animals and write about their findings. ³ Counselling, peer support groups and training in stress management and self-care are recommended institutional responses. ¹

Recommended support for students includes: ⁴

• Provide easily accessible counselling and mental health services.
• Offer workshops on stress management, resilience and coping strategies.
• Establish mentorship programmes that promote healthy mentor–mentee relationships and help students navigate academic challenges.

Principal investigators should: ^{5, 6}

• Model healthy behaviour and encourage a healthy work–life balance.
• Foster communication in which students can discuss mental health concerns without fear of judgement or repercussions.
• Help students access mental health resources and develop coping strategies.

Open discussion, training to recognise and address mental health problems, and a non-judgemental atmosphere can reduce stigma and support wellbeing. ⁶

Students’ own support and coping

Graduate students should take an active role in managing their mental health: ⁶

• Recognise signs of mental distress and act to address them.
• Use available services and seek professional help when needed.
• Develop coping strategies, including exercise, mindfulness and a healthy work–life balance.

Alternatives and writing up the work

Changes to animal research should consider the needs of the people doing it, including their responsibility to write it up and their possible transition into industry medical writing. ⁷ Methods that replace or minimise animal use can relieve ethical dilemmas and emotional distress while supporting a more positive working environment. ²

Writing results can help researchers process and reflect on their experiences and find meaning and purpose in the work. ⁶ Detailed reporting can also make ethical considerations and humane practices transparent, supporting accountability and ethical responsibility. ⁶
