Nesting syndrome: An unexpected burst of energy and a desire to clean shortly before giving birth. This phenomenon has a scientific explanation.
From the outside, it’s curious: a woman who has been feeling incredibly tired over the past weeks suddenly feels a huge surge of strength and rushes to clean up the house. This happens to many expectant mothers about one to two weeks before giving birth [1].
Pregnant women with very big bellies will tirelessly dismantle wardrobes, decorate the nursery, wash the floors, and sweep behind the stove and fridge.
This phenomenon has been called the nesting syndrome, similar to the behavior of birds preparing a place to incubate their eggs. The same behavior is typical for most mammals: before the birth, they create a safe environment for their offspring. Today scientists are inclined to believe that the same mechanism works in humans [2].
The surge of activity that occurs in expectant mothers before childbirth is logical from the point of view of evolution. The baby is small and defenseless, so the place where you bring it after delivery is very important. Baby should be warm, comfortable and safe there [3].
Where does the surge of energy come from?
The exact nature of this phenomenon in humans is still not fully understood. But researchers have learned from other animals that the drive to nest is influenced by the hormones estrogen, progesterone and prolactin [4, 5, 6].
In addition, the psychological component also plays a significant role. By cleaning the house and putting things away, expectant mothers can soothe anxiety before childbirth [3]. These specific actions become a kind of ritual. While there is a lot happening that mama can’t control — cleaning and preparing is one thing she can do [7].
Such rituals cannot completely relieve anxiety, but they can provide temporary relief. If you feel that vigorous activity is just an excuse to drown out feelings, then it it's a good idea to take a moment and reflect on your feelings and share them with a partner or loved one.
Is nesting harmful?
No, this behavior is natural in late pregnancy. Of course, you need to adhere to reasonable safety rules. Don't lift weights, don't overwork, and be sure to take breaks and ask for the help you need. You shouldn't climb a ladder to dust off the chandelier or the top shelves of the cabinet, but rather ask your partner or friend to do this.
What if my partner is not thrilled with my zeal?
Your partner may not match your energy level, but certainly can help out with a couple of cleaning assignments. If he’s not as ambitious as you are, do not accuse him of laziness, most likely, he is just bewildered.
Until recently, you complained of fatigue, but now you work tirelessly. In addition, he cannot read your mind and cannot know why you gained a new gust of energy. So talk to him about your emotions: very often this helps to relieve any tension [3].
