First of all, we should adjust the pace of work and daily life and not be too nervous and tired. Ensure adequate rest and sleep time, rest for half an hour after each meal, rest for two hours in the afternoon, and sleep for 9~ 10 hours every night. If you don't have the conditions to lie down and rest at work, you can raise your legs after lunch, put them on a chair and take a semi-sitting position. Do not stand or sit for a long time. Prevent emotional excitement and avoid more intense or long-term physical labor.

Secondly, pay proper attention to nutrition. Eat a high-protein and low-carbohydrate diet. It is ideal to gain weight 10 kg throughout pregnancy. Diet should be light, but it is not completely forbidden, because the hormone that excretes sodium is added to the body in the third trimester.
