• Avoid Lifting Heavy Weight : Because of many hormonal changes your body is already vulnerable to injury during pregnancy , it is a good idea to not lift any object which is heavy especially by bending forward and always call for help.
• Firm Mattress & Back Support Chair : One should always sleep on a mattress which is not too soft as it leads to back pain.

Also if you have to sit on a chair, it is always good to sit on a chair which has a good lower back support (lumbar support).
