What causes insomnia in pregnancy?
During pregnancy, insomnia can be caused by a variety of different mental health conditions or sleep disorders. Physical changes to the body during pregnancy also make it difficult to get quality rest.
Mental health, pregnancy, and insomnia
Anxiety, depression, post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD) can all cause and/or worsen insomnia symptoms during pregnancy. Feelings of worry or stress about upcoming life changes can also cause sleep disruptions.
Physical changes and sleep
- Increased pressure on the bladder, making you need to urinate more often at night
- Back and leg pain, which may make it difficult to get comfortable
- Heartburn and chest pain that often gets worse before bedtime
- Changes to normal body processes — such as shortness of breath or a faster heart rate — which can make it harder to fall asleep
