One of the biggest impacts of Post-Traumatic Stress Disorder (PTSD) on a person’s health is that it disturbs the sleep cycle. People with PTSD often suffer from a lack of sleep or irregular sleeping timings. Usually, a healthy person takes 7-8 hours of sleep every day. However, PTSD significantly decreases the number of sleeping hours and can also lead to insomnia. PTSD not only reduces sleeping hours, but it also results in bad sleep. For example, a healthy person gets a sound sleep for the time they are in bed. However, people with PTSD often experience broken sleep, which means they would wake up again and again in sleep.
