Due to decreased immunity during pregnancy, women are particularly susceptible to infections from external microbes, leading to respiratory illnesses such as the common cold. The cold can cause symptoms like nasal congestion, runny nose, and sneezing, which can reduce the amount of oxygen inhaled. As the brain's demand for oxygen cannot be met, this can result in symptoms of dizziness.

Since pregnant women cannot use medications due to the development of the fetus within, if dizziness occurs due to a cold during pregnancy, one can inhale some oxygen as a remedy. Additionally, using a hot towel on the nose to improve breathing can also help alleviate symptoms of dizziness.
