In most airports, passengers walk through metal detectors, which use a low-frequency electromagnetic field to look for weapons. Anything that generates or uses electricity, such as power lines or household appliances, produces an electromagnetic field. At the low levels a metal detector emits, this exposure is considered safe for everyone, including pregnant women. (The same holds true for the wands that security personnel sometimes pass over individual passengers.)

When pregnancy occurs, your body goes through various changes in order to accommodate the growing baby, leading to eventual birth. Virtually all your body functions make some adjustments. Some changes are hardly noticeable, while other changes will give you all kinds of symptoms. You are likely to get irritated by some symptoms, but most of them are just innocent and don’t usually require any specific actions.
