Sleep Well: The Relationship Between Sleep and Menopause

We know that sleep is essential for allowing our bodies time to rest and recharge. In many ways, sleep is the foundation for a healthy lifestyle. But with all the distractions and stressors coming at us each day, achieving a restful night’s sleep isn’t always easy. In fact, according to the Center for Disease Control and Prevention, one in three Americans aren’t getting enough sleep.

Our multi-part series, Sleep Well, examines the power of sleep and how it relates to our health throughout our lifespan – from our menstrual cycles to fertility, and menopause – and offers advice on how to get better sleep tonight. In this issue, we dig into the connection between menopause and sleep. Dr. Jeanette McDonald of Axia Women’s Health – OB/GYN of Indiana shares her insight.

The Science Between Menopause and Sleep

“Many factors can affect the sleep/wake cycle of midlife women,” says Dr. McDonald, “It’s common to feel tired earlier and wake earlier as we age. However, during menopause, certain conditions can develop that can further disrupt our sleep.” In fact, according to the National Sleep Foundation, 61% of perimenopausal and postmenopausal women experience frequent insomnia.  Fortunately, there are treatments that can help you to rest easier. The first step is understanding what exactly is keeping you up at night.

Before we explore the potential causes of sleep disturbances, it’s important to understand what’s happening inside our bodies during menopause. During menopause, women experience a gradual loss of the hormones estrogen and progesterone.

“When hormone levels are low, women can experience some of the troubling vasomotor symptoms associated with menopause including hot flashes or night sweats. Besides hot flashes and night sweats, another cause of sleep disturbance that can occur during menopause is sleep apnea. While heavy body weight is a significant cause of sleep apnea, declining ovarian hormones, particularly progesterone, also play a role in sleep apnea.”

 

Potential Causes of Sleep Disturbance During Menopause

Hot flashes and night sweats

Hot flashes are a common occurrence during menopause, affecting up to 75% of women during the menopausal period, according to the North American Menopause Society. Hot flashes are defined as a sudden rush of increased body heat followed by a cool sweat, typically lasting a couple of minutes.

“Nighttime hot flashes, also called night sweats, can trigger arousal and awakening, especially during the first half of sleep,” adds Dr. McDonald.

Experts believe that decreased estrogen levels may cause your hypothalamus in your brain, which regulates your body temperature, to become more sensitive. When your body senses that it’s too hot, it tries to cool itself down, causing you to experience a hot flash. So, what’s there to do about it?

If your hot flashes can’t be managed by lifestyle adjustments, treatments may be able to help.

“Hormone replacement therapy with estrogen and progesterone can improve sleep disturbances due to hot flashes. There are many routes including oral, transdermal (through the skin), and vaginal.” As with any treatment, it’s important to discuss the risks/benefits with your provider.

According to a study published in Menopause, women taking hormone therapy sustained significant improvement with hot flashes and night sweats (both frequency and duration) over a four-year treatment period.

“For women with sleep disruption due to hot flashes who cannot take estrogen, there are other vitamins and herbal supplements that can help such as estroven, black cohash, valerian root, and melatonin.”

Sleep Apnea

According to a study published in the medical journal Pulmonology, postmenopausal women are three times more likely to experience obstructive sleep apnea (OSA) compared to premenopausal women. Obstructive sleep apnea, the most common subtype of sleep apnea, is defined by pauses of reduced breathing during sleep due to complete or partial blockages in your airway.

These pauses can occur anywhere between 5 to more than 60 times in one hour before regular breathing resumes. One of the most obvious symptoms associated with sleep apnea is snoring. Experts believe that a decrease in estrogen and progesterone could again be responsible for the correlation between menopause and sleep apnea, as they support the airway muscle and keep it from weakening or collapsing. The good news: there are multiple treatments that can help:

Other conditions that can be keeping you up at night could include incontinence, joint pain, or mood disorders. It’s important to understand the root cause in order to properly treat it.

Further exploration with a sleep study or mental health evaluation may be appropriate and may indicate other condition specific treatments that can improve sleep.

Menopause can be a challenging transition to navigate, but you don’t have to go it alone.  If you have concerns, speak with your Axia Women’s Health provider who can help you develop a plan to achieve a better night’s sleep.
