Cold night sweats are often reported by women during pregnancy

What Are Night Sweats?

Night sweats are when you wake from sleep shivering and cold. Cold night sweats can often leave you fatigued and anxious because sleep patterns are regularly disturbed. When night sweats happen frequently, they can become a serious issue, disrupting your natural sleep rhythms. During pregnancy, it's important to remain relaxed and well-rested to maintain your own health and the baby's.

What Causes Cold Night Sweats during Pregnancy?

The exact causes of cold night sweats during pregnancy are unknown. However, it's widely believed that cold night sweats result from changing hormone levels in the body. Cold sweats occur when estrogen and progesterone levels in the body fluctuate, becoming out of balance. When these hormones are out of balance, it can confuse your body into thinking that it's cold, causing it to warm itself up before realizing it's too warm and starts sweating to compensate. This can lead to shivering chills accompanying your cold sweats.

How Can Night Sweats Be Managed?

Before attempting medical treatment for night sweats, it can be beneficial to try preventative measures. There are many lifestyle changes that can be undertaken to help with night sweats during pregnancy. These include:

  • Sleep in a cool room. Turn a fan on or turn the thermostat down before bed.
  • Sleep with a light blanket or layer your blankets so that it's easier to regulate your temperature.
  • Wear light, loose-fitting clothing. Try to avoid synthetics and wear more natural fibers, such as cotton.
  • Drink plenty of water.
  • Avoid spicy foods, especially before bed.
  • Take a cool shower before bed to cool down.
  • Exercise regularly.
  • Practice relaxation exercises such as yoga, Pilates, or meditation.
