Managing hypervigilance and heightened arousal, common symptoms of PTSD, requires a multi-faceted approach. Breathing exercises and relaxation techniques can help reduce the physiological responses associated with hypervigilance. Practicing mindfulness can promote awareness of the present moment, allowing you to identify triggers and manage overwhelming sensations. Establishing a routine that includes regular exercise, healthy eating, and sufficient sleep can contribute to overall emotional regulation. Gradual exposure to triggering situations, under the guidance of a therapist, can help desensitize hypervigilance over time.
