Prevention of concussions
Prevention of mild traumatic brain injury involves taking general measures to prevent traumatic brain injury, such as wearing seat belts and using airbags in cars. Older people are encouraged to try to prevent falls, for example by keeping floors free of clutter and wearing thin, flat, shoes with hard soles that do not interfere with balance.
Trauma trigger
The mental health effects of trigger warnings have not been well studied. In cautioning university faculty against the widespread use of trigger warnings, Richard McNally, a Professor of Psychology at Harvard University, noted that "Trigger warnings are designed to help survivors avoid reminders of their trauma, thereby preventing emotional discomfort. Yet avoidance reinforces PTSD. Conversely, systematic exposure to triggers and the memories they provoke is the most effective means of overcoming the disorder." Similarly, Metin Basoglu, a psychiatrist specializing in trauma research, said that "instead of encouraging a culture of avoidance, [the media] should be encouraging exposure. Most trauma victims avoid situations that remind them of the experience. Avoidance means helplessness and helplessness means depression. That's not good."
