Are You Having Sleepless Nights

People who feel the night is long visit the clinic. We especially often hear, from women around menopause, that even when they lie down they toss and turn for a long time, and the sleep they barely fall into is broken at dawn and they cannot fall back asleep. Sleep problems around menopause are often not simply a slump in condition but are created by the entanglement of hormonal change, hot flashes and sweating, and mood changes. In this article, rather than the definition or diagnosis of insomnia, I will organize, centered on why menopausal women's sleep is shaken and the management and sleep hygiene we recommend in the clinic.

Sleep problems around menopause are reported comparatively commonly in a woman's life cycle. In the menopausal transition, as hormones including estrogen change rapidly, the brain's signaling system in charge of temperature regulation and sleep is affected together. In the clinic, we often hear the expression "I used to fall asleep the moment my head touched the pillow, but lately it's not like that," and it is more accurate to understand this not as merely a matter of age but as the result of an added change in the hormonal environment.

The American College of Obstetricians and Gynecologists (ACOG) and The Menopause Society explain that sleep problems in the menopausal transition appear from the overlap of several factors—menopause itself, vasomotor symptoms such as hot flashes and sweating, anxiety/depression, aging, and existing sleep disorders. In other words, rather than concluding it is one cause, examining which factor acts more strongly is the starting point of management. If you are curious about the body's changes in menopause overall, we recommend reading together menopausal body changes and symptoms, causes and mechanisms.

Hot flashes and sweating that come at night are a representative channel that breaks down menopausal sleep. Those who have the symptom of the face flushing during the day commonly also experience so-called night sweats, and sudden heat and sweat in the middle of the night make sleep shallow and become a cause of waking midway. The Menopause Society reports that hot flashes and sweating appear in a considerable number of women in the menopausal transition and can persist on average over several years.

The problem is that once you wake, it is hard to fall back asleep. After waking from heat, throwing off the blanket, cooling the sweat, and lying down again, the already-aroused brain does not easily settle. When such nights repeat, you become tense "in case I wake again," and that tension itself leads to a vicious cycle that again disturbs sleep.

If hot flashes greatly shake daily life and sleep, it is good to receive a consultation rather than leaving it alone. Relatedly, it is explained in more detail in facial flushing, the reason you should not leave it untreated.

Sleep problems and mood changes are not one-directional but influence each other. If there is depression or anxiety, dissatisfaction with sleep grows, and conversely, long-lasting sleep problems lower the mood. This is why, when hearing about sleep in menopausal care, we also ask about the mood state.

In fact, insomnia and depression often appear interlocked, and the point that chronic sleep problems can be a risk factor and early signal of depression is emphasized in various practice guidelines. The American College of Physicians also recommends that, when evaluating chronic insomnia, you examine together accompanying factors that disturb sleep, such as depression, pain, and other sleep disorders. So in the clinic, we confirm parts such as the following together.

• The time it takes to fall asleep, the number of awakenings, and the pattern of falling back asleep after waking
• Whether vasomotor symptoms such as nighttime heat and sweating wake you
• Whether mood changes, anxiety, or decreased motivation accompany
• Lifestyle factors that shake sleep, such as caffeine, alcohol, and naps

In clinical experience, looking at sleep in isolation makes it easy to miss the cause. Only by examining mood, lifestyle habits, and physical symptoms together does it become clear which part to address first.

Sleep hygiene is the most basic management of tidying up the environment and habits that invite sleep. It is a foundation that must be kept together before medication or procedures, and whatever treatment you receive. Organizing what the US Centers for Disease Control and Prevention (CDC) and the American Academy of Sleep Medicine (AASM) recommend, suited to the menopausal situation, is as follows.

• Keep consistent wake and bedtimes, and do not deviate greatly even on weekends.
• Avoid caffeine after late afternoon, and reduce drinking close to bedtime.
• Get plenty of sunlight during the day, especially in the morning, and move your body regularly.
• Exercise is good, but avoid strenuous exercise right before sleep.
• Reduce bright screens such as smartphones and TV and stimulating activity before sleep.
• Keep the bedroom cool, dark, and quiet, and make pajamas/bedding breathable.

In particular, in menopause, bedroom temperature and bedding management make a big difference. A cool environment, bedding with good moisture-absorption and ventilation, and an environment where you can quickly cool the heat when you wake help reduce arousal due to night sweats. The key is to steadily build up from small changes.

There are people whose sleep problems do not improve sufficiently even after tidying up lifestyle habits. In this case, it is good to decide the next step together through a medical visit rather than holding out alone. For chronic insomnia, the American College of Physicians recommends considering cognitive behavioral therapy (CBT-I) before medication, and this is reported as an approach that addresses the thought and behavior patterns that disturb sleep and helps over the long term.

Depending on the background of the sleep problem, the approach considered first differs. The table below organizes the broad framework referred to when setting direction in the clinic; the actual choice may differ according to individual state.

In the case of menopausal women, it is not uncommon for vasomotor symptoms such as hot flashes and sweating to lie largely behind the sleep problem. ACOG and The Menopause Society explain that, for such vasomotor symptoms and the resulting sleep problems, systemic hormone therapy is reported as an effective option. However, since the suitability of hormone therapy differs according to the individual's medical history and risk factors, it must be judged individually only after differentiation of other causes and consultation. If you are curious about hormone therapy, refer to menopausal hormone care and menopause screening items, and we recommend deciding the direction suited to you together in consultation.

We examine menopausal sleep problems from multiple angles rather than ending with a single prescription. To help those spending hard nights with depression, anxiety, and insomnia due to hormonal change, in the clinic we confirm the sleep pattern, mood, lifestyle habits, and vasomotor symptoms together, and when needed, we are broadening the direction of approach through collaboration with experts in the field of neuroengineering.

What is important is not to endure and let it pass with "everyone is like that when they get older." Since sleep problems can affect not only quality of life but mood and overall health, if there is interference with daily life, we recommend checking once. If you have other menopausal symptoms together, a menopausal symptom check is also helpful.

Insomnia after menopause is not because of weak willpower, nor simply because of getting older. It is often the result of hormonal change, hot flashes, and mood changes overlapping on top of sleep, and so an approach that examines the cause together on the foundation of sleep hygiene is needed. If sleepless nights are growing long, do not hold out alone but feel free to inquire.
