Pregnant and sleeping for two or more? If so, your sleep quality may change – especially by your third trimester.
Increased sleep complaints during pregnancy are often due to endocrine and physiologic changes in the body. The increase in progesterone that accompanies pregnancy naturally increases fatigue, raises body temperature, increases respiratory rate and intensifies the need for frequent urination. Physical changes such as the increase in abdominal mass and vascular load all lead to poor sleep quality.
Often during the first trimester, there is an increase in total sleep time and the need for naps; however, sleep quality can be poor due to frequent awakenings during the night.
Initial changes in sleep patterns typically occur in the first 12 weeks of pregnancy and then increase during the third trimester and early postpartum weeks. Be aware of:
- slight decreases in Rapid Eye Movement (REM) sleep
- decrease in deep sleep
- decrease in sleep efficiency
- increased awakenings after initially falling asleep
Women who have never before snored may begin to do so when pregnant. Snoring in expectant mothers is caused from inflammation in the nasal passages. This can lead to Obstructive Sleep Apnea, caused by a blockage in the airway, which is a very dangerous condition. It can cause death if not treated.
A condition known as Restless Legs (RLS) can also develop during the third trimester of pregnancy which causes an uncontrolled urge to move the legs. A contributing factor often may be iron or folic acid deficiency, so be sure to tell your doctor if you have these symptoms.
The best tips for a good night’s sleep when expecting: learn to relax utilizing breathing and other relaxation techniques. A warm shower or bath may also be helpful.
