First Trimester
Extreme fatigue is normal — progesterone rises sharply. Aim for 8–10 hours and nap when needed.
Second Trimester
Most comfortable trimester for sleep. Start side sleeping to prepare for third trimester.
Third Trimester
Discomfort peaks. A full-body pillow, left-side sleeping, and limiting fluids before bed all help.
Frequently asked questions
How much sleep do you need during pregnancy?▾
Pregnant women generally need 8–10 hours per night — more than the 7–9 hours for non-pregnant adults. Sleep needs are highest in the first and third trimesters.
Why is sleep so important during pregnancy?▾
Sleep supports fetal development, immune function, and hormone regulation. Poor pregnancy sleep is linked to gestational diabetes, preeclampsia, longer labor, and postpartum depression.
What is the best sleeping position during pregnancy?▾
Left-side sleeping is recommended from the second trimester onward — it improves blood flow to the placenta. A pillow between the knees reduces hip and back strain.
Why can't I sleep in the third trimester?▾
A growing belly makes all positions uncomfortable, frequent urination disrupts sleep, restless leg syndrome peaks, and anxiety about labor rises. A full-body pregnancy pillow helps significantly.
