Sleep On Your Left Side
The Mayo Clinic recommends that pregnant women try sleeping on the left side of their body to reduce the pressure on the vena cava. This is the largest vein that returns the blood from your lower body to your heart. By sleeping on your left side, the pressure on the vena cava is significantly reduced thus allowing better blood flow, and this reduces swelling.
Reduce Your Intake of Salt
Pregnant women are at a higher risk of developing hypertension, and this can even be dangerous for the baby. Too much salt in your diet can increase your risk of high blood pressure, but it might also worsen water retention. Make sure to season your meals with as little salt as possible to avoid hypertension and swelling. If you are experiencing nausea and vomiting even 14 weeks into your pregnancy, do contact your doctor as this could be a sign of a hypertension crisis rather than morning sickness.
Hot weather and warm interiors can cause the blood vessels in your extremities to dilate leading to a greater water retention in your hands and feet. Keep yourself comfortably cool, especially in late pregnancy when swelling tends to become worse. Applying cold compression on swollen angles can also provide some relief and reduce some of the swellings after a long day of standing.
