How can sleep monitoring help track progress during PTSD treatment?

PTSD recovery is often uneven, making it difficult to judge progress from day-to-day feelings alone. Long-term sleep monitoring can add objective information about sleep duration, awakenings, heart rate, HRV, oxygen levels, and oxygen drop events. Changes in these measurements may help patients and clinicians see whether nighttime recovery and physiological stress are improving over time. Sleep monitoring does not diagnose or treat PTSD, but it can provide additional context for treatment discussions and decisions.
