In our libido doctor programs we go through how sleep is related to a healthy libido. Sleep research shows us that when women get longer sleep not only do they have more desire, but their genital arousal also improves. It is also noteworthy, that even if you think you are sleeping throughout the night, you may not be getting deep sleep. Sleep tracking devices such as the oura ring can help to provide data to let you know proper sleep levels.
Labs for sleep: If you are concerned about sleep, it is worth talking to your doctor about a nocturnal oximetry test as well as a full sleep function test. If you cannot get this done by your doctor, I recommend an organization called Vivos that tests for these sorts of issues. One of the biggest concerns with poor sleep is sleep apnea, which is when we stop breathing at night for short periods. This leads to a huge amount of sleep disruption. Often times doctors will not order this unless you are overweight as there is a big link between excess weight and sleep apnea. While this link is true, I have seen plenty of people over years at their ideal weight that still suffer from sleep apnea.
