Causes of Low Libido in Women
1. Lack of Sleep
A good night's rest might be hard to come by, but you need sleep to keep a sharp mind, a healthy body, and an active libido. Physically, a lack of sleep can elevate cortisol levels, which also leads to low libido.

2. Medication
Some medications used to treat depression, high blood pressure, and other common illnesses can affect libido.

3. Hormone Imbalance
Libido is directly influenced by testosterone levels. Therefore, low libido is often caused by low testosterone levels - a hormone imbalance. Other causes of a hormone imbalance include cirrhosis of the liver or pituitary diseases. 

4. Menopause
Women may experience low libido during menopause for a number of reasons. Estrogen levels drop suddenly during these years, causing vaginal tissue to become dry. That, in turn, can lead to discomfort and pain during intercourse and discourage a woman’s sexual desire. Menopause can also lower testosterone, the hormone that boosts libido in women as well as men.

5. Stress
The body reacts to stress by releasing adrenaline and cortisol. Chronic stress, in particular, can interfere with your body’s hormone levels, and result in a low libido. The arteries can also narrow and restrict blood flow in response to stress, which can also lead to erectile dysfunction. Stress can also reduce your libido by distracting you and taking your mind off sexual desire.

6. Depression
Libido and depression share a complicated link. Depression can change the body's biochemistry and therefore reduce libido. Some medications commonly used to treat depression may also lower libido as a side effect.
