Navy Suicide Prevention Month and Efforts
Suicide Prevention Month is not just a 30-day blitz of suicide prevention efforts; it is the starting point for year-long conversations about how to be there for every Sailor, every day. It serves as a launchpad to reengage with topics that help promote a culture supportive of psychological health, emotional wellness, protective factors, connectedness and seeking help. This September, the Project 1 Small ACT campaign will continue to lead the charge for the Navy’s year-long suicide prevention efforts, fostering meaningful dialogue about psychological health, suicide, early intervention, recognizing risk and warning signs, lethal means safety, self-care, and connection.
