It is normal for pregnant women to sweat in bed at night. When you are pregnant, your metabolism increases, so you tend to sweat at night. I believe we don't know much about Night Sweats. So let's start with what we know about Night Sweats.

What Are Night Sweats?

We often refer to night sweats when we fall asleep and stop sweating when we wake up, as opposed to other normal sweating. Whenever we fall asleep, or when we close our eyes and are about to fall asleep, or when we sleep in the middle of the night, sweat sneaks out like a thief. The amount of sweating varies from person to person and night sweats are classified according to the amount of sweating. In severe night sweats, the sweat comes out very easily. Soon after falling asleep or just before closing the eyes, the sweat will come out in large quantities and the sweat will be awakened. When you go back to sleep, you may sweat again. The sweat is often salty, or sweat mixed with sweat odor. These patients are often accompanied by an obvious feeling of heat, irritability, and a dry mouth after sweating. The condition can worsen over time, seriously threatening the health and life of the patient.

What Causes Pregnancy Night Sweats?

Night sweats during pregnancy are a signal from the body. In general, night sweats during pregnancy are mainly caused by physical weakness, and the main symptoms are sweating without exercise when the temperature is not high, and some people sleep with sweat all over their body, especially head sweat, and feel weak and easy to catch a cold. When a woman is pregnant, her estrogen increases and her basal metabolic rate increases, which can lead to a temporary loss of balance in her body. At this time, if a pregnant woman is deficient in trace elements or has weaknesses such as anemia, this may lead to weakness and night sweats.

Other Causes for Night Sweats

There are many other causes of night sweats. Some of the more common ones are:

  • Inadequate blood supply. Insufficient blood supply and brain ischemia are relatively common in pregnant women. Mainly during the 14-27 weeks of pregnancy, due to the formation of the placenta, blood pressure will drop, especially in pregnant women with hypertension, blood pressure will drop significantly.
  • Inappropriate body position. Mainly due to inappropriate position, the uterus presses on the inferior vena cava behind it, causing obstruction of blood flow, resulting in reduced blood supply and dizziness, commonly seen in supine or lying down.
  • Underfeeding. Not eating in time or eating too little, resulting in low blood sugar, pregnant women will also occur dizziness, weakness, cold sweat, so pregnant women need to ensure proper feeding even if they vomit.
  • Calcium deficiency. Women are prone to micronutrient deficiencies after pregnancy, calcium deficiency and iron deficiency are two of the most common, indirectly leading to dizziness and sweating of pregnant women.

    Are Night Sweats Dangerous during Pregnancy?

    Some women who are preparing for pregnancy have the following questions:"Are night sweats a sign of pregnancy?" The answer is no. Night sweats are an abnormal phenomenon of sweating caused by physical weakness or illness, and are not directly related to pregnancy.

    However, women do tend to sweat more when they are pregnant. This abnormal sweating phenomenon is often ignored by many pregnant women because it does not have a significant effect on their bodies. Frequent sweating can lead to dehydration, disturbance of electrolyte balance, and loss of trace elements in the body. In mild cases, they often feel dizzy, weak, pale, loss of appetite, sleepless and thin; in severe cases, they may suffer from muscle twitching, panic and shortness of breath and memory loss. If pregnant women are always like this, it may also cause fetal dysplasia.


    6 Suggestions for Relieving Night Sweats

    In general, night sweats do not pose much threat to our lives. We can first determine the cause of our night sweats and then supplement with the appropriate nutrients.

    3. Eat more vegetables and fruits. This not only replenishes vitamins, but also replenishes the potassium and sodium ions lost from sweat and maintains the electrolyte balance in the body.

Pregnant women can communicate more with their family and friends, or keep a good mood by listening to music or taking a walk. However, you should pay attention to hygiene, go to less densely populated public places, keep indoor air circulation, and exercise properly to enhance your physical fitness.
