Hormones And Sleep: Why Women Need More Shut-Eye

do women need more sleep because of hormones

Women need more sleep than men, and changing hormones are one of the reasons why. Women experience hormonal changes monthly with their menstrual cycles and during major life stages like pregnancy, breastfeeding, perimenopause, and menopause. These hormonal changes can affect the sleep cycle and increase the risk of sleep disturbances. For example, during menopause, women may experience night sweats and hot flashes that wake them up, and lower levels of progesterone can make it harder to relax. Additionally, women are more likely to experience insomnia, depression, and anxiety, which are all sleep disruptors.

Menstruation

Fluctuating hormone levels during the menstrual cycle can impact a woman's sleep. The menstrual cycle is divided into the menstrual, follicular, ovulatory, and luteal phases, each of which is characterised by distinct hormonal changes that can influence sleep patterns.

Menstrual Phase

This phase is associated with the onset of menstruation and a decrease in both oestrogen and progesterone levels. Some women may experience sleep disturbances due to symptoms such as menstrual cramps, breast tenderness, and headaches.

Follicular Phase

This phase is marked by rising oestrogen levels, which can impact sleep architecture and duration. Studies have found that the follicular phase is associated with variable REM sleep, characterised by earlier onset and shorter episodes compared to other phases.

Ovulatory Phase

During this phase, there is a surge in luteinising hormone, which triggers ovulation. The impact of this phase on sleep is not well understood, but some women may experience sleep disturbances due to physical and emotional changes associated with ovulation.

Luteal Phase

The luteal phase is characterised by rising progesterone levels, which can affect body temperature regulation and make it difficult to fall asleep. This phase is also associated with decreased REM sleep and sleep efficiency, indicating more fragmented sleep patterns.

Overall, hormonal fluctuations during the menstrual cycle can influence sleep quality and duration. Additionally, individual factors such as age, lifestyle, diet, genetic factors, and activity levels can also impact sleep during this time. To manage sleep disturbances during menstruation, hormonal management, lifestyle modifications, sleep hygiene practices, and cognitive-behavioural therapy can be considered.

Pregnancy

By the third trimester, progesterone and estrogen levels even out. However, other factors, such as frequent urination, restless leg syndrome, and difficulty breathing, can make it challenging to get a full night's rest. These issues can contribute to adverse health outcomes for both mothers and babies. For instance, lack of quality sleep during pregnancy has been linked to low infant birth weight and preeclampsia, a severe blood pressure condition.

To promote better sleep during pregnancy, Dr. Christine Won recommends sleeping with your head elevated to reduce pregnancy-related reflux and snoring. Exploring cognitive and behavioral therapies, as well as relaxation techniques, can also aid in winding down and improving sleep quality.

Additionally, it is worth noting that the risk of developing sleep apnea increases during pregnancy. Sleep apnea is a sleep disorder characterized by pauses in breathing, which can interfere with sleep quality and leave individuals feeling less refreshed upon waking.

Menopause

Women's sleep needs are impacted by changing hormones, mental health issues, and a higher risk for sleep disorders. Fluctuating hormones, such as those experienced during menopause, can affect a woman's sleep cycle and increase the risk of sleep disturbances.

  • Taking longer to fall asleep.
  • Spending less time in deep sleep.
  • Developing sleep disorders such as sleep apnea and restless legs syndrome, which may be linked to hormonal changes and weight gain.
  • Experiencing hot flashes and night sweats, which can make it harder to fall back asleep.
  • Increased risk of developing insomnia due to anxiety and depression, which may be triggered by hormonal changes and life circumstances.
  • Snoring, which can be a symptom of sleep apnea, becomes more common due to declining reproductive hormones and weight gain.

Managing Menopause-Related Sleep Disturbances

  • Follow a regular sleep schedule: Go to bed and wake up at the same time each day.
  • Avoid late afternoon or evening naps as they may interfere with nighttime sleep.
  • Develop a relaxing bedtime routine: Read a book, listen to soothing music, or soak in a warm bath.
  • Avoid screen time before bed: The light from electronic devices can disrupt sleep.
  • Keep the bedroom cool, quiet, and comfortable.
  • Exercise regularly, but not too close to bedtime.
  • Avoid large meals, caffeine, and alcohol before bed, as they can disrupt sleep.
  • Manage stress: Incorporate mindfulness meditation or other stress-reduction techniques into your bedtime routine.
  • Seek help: If sleep disturbances persist, talk to your doctor. Cognitive-behavioral therapy for insomnia has been shown to help improve sleep in menopausal women.

Hormones and sleep-wake cycle

The sleep-wake cycle is ruled by hormones. These hormones affect when a person feels tired, when they feel alert, and when they feel hungry. Women experience hormonal changes each month and over the course of their lifetimes, which impact their circadian rhythms and create a greater need for sleep.

Menstruation

One-third of people who menstruate have trouble sleeping due to cramps, headaches, and bloating. They report higher levels of daytime sleepiness, tiredness, and fatigue. During the week before their period, a woman's progesterone levels will rise to prepare her body for a potential pregnancy. If there is no pregnancy, progesterone levels decrease dramatically, causing the uterine lining to shed and starting the menstrual cycle. Immediately before bleeding begins, a woman's progesterone levels dip dramatically, which is why some women can find it really difficult to get quality sleep in those "PMS" days.

Pregnancy

During pregnancy, women may develop restless legs syndrome, a condition that makes it harder to fall asleep. Pregnant people are also more likely to experience depression, sleep apnea, pain, and incontinence, which disrupt their sleep. These sleep issues can persist into the postpartum period, when their hormone levels drop at the same time they start taking care of a newborn with an irregular sleep cycle — often resulting in even more daytime sleepiness.

Menopause

During menopause, up to 85% of women experience hot flashes. When these occur at night, women wake up in a sweat, disrupting their sleep. The risk of developing sleep apnea also increases during menopause. This sleep disorder causes pauses in breathing that can interfere with the quality of one’s sleep. As a result, women with sleep apnea may feel less refreshed upon waking up and experience tiredness and excessive sleepiness during the day.

Hormones and sleep disorders

Hormones play a significant role in sleep patterns, with women experiencing more sleep issues than men. Women's sleep needs are influenced by changing hormones, mental health issues, and a higher risk of sleep disorders.

Fluctuating Hormones and Sleep

The interplay between hormones and sleep is bidirectional, with hormones affecting sleep and sleep-wake cycles influencing hormone production. Women experience hormonal changes throughout their lives, including menstruation, pregnancy, and menopause, which can impact their sleep.

#### Menstruation

During the week before menstruation, progesterone levels rise in preparation for potential pregnancy. If pregnancy does not occur, progesterone levels drop, triggering the menstrual cycle. This dip in progesterone can make it challenging for some women to get quality sleep during their "PMS" days.

#### Pregnancy

Pregnancy is a time of significant hormonal changes, with rising levels of progesterone and estrogen supporting the growing fetus. In the first trimester, women often experience increased drowsiness and take more naps due to elevated hormone levels. In the third trimester, other factors like frequent urination, restless leg syndrome, and difficulty breathing can disrupt sleep.

#### Menopause

Menopause is marked by fluctuating hormone levels, resulting in night sweats and hot flashes that can disrupt sleep. Lower progesterone levels can also contribute to irritability and difficulty relaxing. Additionally, menopause increases the risk of developing sleep apnea, a disorder that interrupts breathing during sleep.

Mental Health and Sleep

Mental health and sleep are closely linked. Poor sleep can negatively affect mental health, and depression and anxiety are associated with insomnia. Women are twice as likely as men to experience anxiety and depression, which further increases their risk of sleep disturbances.

Sleep Disorders

Women are more likely than men to experience sleep disorders, and this risk increases with age. They are more susceptible to conditions like restless leg syndrome and sleep apnea, especially during and after menopause. Additionally, gender-based responsibilities, such as caregiving, can further impact sleep duration in women.

In summary, hormonal changes, mental health issues, and sleep disorders are key factors contributing to the higher prevalence of sleep issues in women. These factors interact in complex ways and can have significant implications for women's overall health and well-being.
