Feeling overheated? Chalk it up to increased blood volume. During pregnancy, the amount of blood in your body increases by as much as 50 percent. To better handle all that extra blood, your blood vessels dilate slightly, allowing the blood to come of the surface, which can make you feel hot.

In the third trimester, your metabolic rate also increases, which can also add to that overheated feeling. You might find yourself sweating more too.

The good news? Your blood volume—and internal thermostat—will return to normal after delivery. Until then, you’ll have to find ways to deal with feeling hot. Consider dressing in light layers so it’s easy to add or remove clothing quickly as needed. You should also drink plenty of water. Staying well hydrated will prevent dehydration and make you feel more comfortable, especially when it’s  hot outside. Consider investing in a couple fans—we recommend having one on your desk at work and one in your bedroom.
