Afflicted by another night of tossing and turning despite a tiring day of juggling deadlines and responsibilities? This experience is quite common for women in their late thirties and early forties, with many being affected by sleep issues. 

Beyond daily stressors, these sleep disturbances are the result of significant hormonal fluctuations that occur during this life stage. Let’s identify the primary hormonal drivers behind your restless nights and set the stage for actionable strategies that will help you lessen their toll on your sleep quality.

Identifying the Main Culprits

There’s a connection between your sleep quality and the ongoing dance of fluctuating hormones inside your body. Estrogen, progesterone, cortisol, and melatonin: each has its part to play in the regulation of your sleep-wake cycle. When the dance is less harmonious, your sleep quality pays the price.

• Estrogen: It helps regulate your body’s temperature and supports the production of serotonin, which is then converted into melatonin, your body’s natural sleep hormone. As estrogen levels fluctuate throughout your menstrual cycle, or start their decline with perimenopause, you might wake up at night in a sweat or struggle to fall asleep.
• Progesterone: It promotes rest and relaxation during the second part of your menstrual cycle. As your body’s natural sedative, it aims to promote better sleep during this phase. Certain factors, such as irregular ovulation or entering perimenopause, can affect progesterone levels, which can lead you to feel anxious and restless at night.
• Cortisol: Best known as your primary stress hormone, cortisol needs to drop at bedtime for melatonin to rise. Yet the demands of modern life can keep cortisol at an all-time high when you need it to decline. This is when the vicious cycle starts, as poor sleep leads to increased stress, which in turn disrupts sleep patterns.

Reclaiming Your Hours of Sleep

As you get older, hormonal patterns are more likely to sabotage your sleep cycle. It is thus crucial to understand these fluctuations in order to reclaim restful nights. Track your menstrual cycle and learn how the quality of your sleep varies throughout the month. Sleep quality usually increases the week after ovulation, when progesterone levels are at their highest.

Tips for creating an evening routine that promotes better sleep:

• Prioritize a consistent sleep schedule to help regulate your body’s internal clock.
• Pay attention to your diet and drinking habits, as certain foods and beverages can disrupt sleep patterns.
• Utilize relaxation techniques, such as yoga, meditation, breathing exercises, or a warm bath. They can help you ease out of the day’s stressors and calm your mind.
• Dim lights a couple hours before bedtime to encourage the production of melatonin.
• Counter temperature fluctuations by keeping your bedroom cool and dark.
• Exercise regularly, but avoid intensive workouts four hours before bedtime.

If your sleep hygiene does not improve despite your best efforts, don’t hesitate to reach out to a specialized healthcare provider who can help you address the underlying causes behind insomnia, fragmented sleep, and daytime fatigue. Cognitive Behavioral Therapy (CBT) and sometimes Hormone Replacement Therapy (HRT) can be effective treatments when lifestyle changes and supplements alone don’t show results.
