Can your body shut down when you're pregnant and have insomnia? just something i heard

I'm not sure: What you mean, but no, your body doesn't ever "shut down", except when you die. Be careful who you listen to, as they're rarely ever correct on any topic.

NOT: I agree with my colleagues. Your body is able to heal and rebalance itself as long as you're alive. Only death makes your body "shut down." pregnancy represents a lot of change, but your body is resilient. If having trouble sleeping, tell your doctor.
