Sleep and the menstrual cycle are closely linked. Research shows that women experience more sleep difficulties than men and are at greater risk of insomnia. This is partly due to hormonal changes throughout the menstrual cycle, which can affect sleep quality. Estrogen and progesterone levels fluctuate, impacting the body's internal clock and sleep. During the second half of the menstrual cycle, hormone levels tend to drop, causing a spike in body temperature, which can disrupt sleep.
Additionally, women's sleep may be affected by physical changes such as pregnancy and menopause, as well as lifestyle factors like work and household responsibilities. These factors can contribute to sleep disorders and insufficient sleep, adversely affecting overall wellness.
To improve sleep during the menstrual cycle, it is recommended to establish a consistent sleep routine, create a calming sleep environment, exercise regularly, and make mindful food choices. Understanding the impact of hormonal changes on sleep and implementing strategies to improve sleep quality can help women optimise their rest and overall well-being.

What You'll Learn

Hormonal fluctuations and sleep
The menstrual cycle is an intricate hormonal rollercoaster that affects virtually every aspect of a person's physiology, mood, and sleep patterns. During menstruation, hormone levels fluctuate significantly, with oestrogen and progesterone dipping to their lowest post-ovulation, leading to a range of physical and emotional changes, including fatigue and mood swings.
The Follicular Phase
As you progress through the follicular phase and your energy and motivation levels begin to rise, you’ll notice improved imagination, perception, memory and social abilities. However, alongside this rise in oestrogen, there’s an increase in energy levels, which may cause you to find it more difficult to fall asleep.
Ovulation
During ovulation, the sharp increase in oestrogen levels can cause sleep disturbances such as insomnia or difficulty staying asleep.
The Luteal Phase
The luteal phase is when progesterone levels rise. Progesterone has a sedating effect and can make you feel more tired than usual. However, it can also contribute to symptoms like restless legs or sleep apnea, which can disrupt your sleep quality.
The Pre-Menstrual Phase
Right before and during your period, both oestrogen and progesterone are on the decline. It's these hormones, particularly progesterone—a natural sleep-promoter—that can leave you feeling drained. The drop in progesterone can make falling and staying asleep more challenging and may even lead to a restless night.
The Menstrual Phase
During the second half of the cycle, progesterone levels rise, which can have a sedative effect. However, this level starts to drop as your period approaches. This hormone is your natural tranquilliser; when it's reduced, you might notice trouble unwinding and drifting into deep sleep.
Oestrogen, known to help regulate the sleep cycle, also takes a hit during your period. Lower oestrogen levels can make you less resilient to stress and more susceptible to sleep disturbances, hence why some women report feeling more vigilant or even insomnia during this time.
The Impact of Hormones on Sleep
There are three different types of oestrogen, but E2 is the most active and abundant form. It plays a big role in regulating the menstrual cycle and affects sleep quality and duration. Research has shown that high levels of oestrogen can lead to increased wakefulness and lighter sleep, making it harder to achieve deep, restorative sleep. Fluctuations in oestrogen levels can also disrupt the production of serotonin, a neurotransmitter that promotes sleep.
Progesterone, on the other hand, has a calming effect on the body and can promote sleep. However, an excess of progesterone can lead to symptoms like snoring, sleep apnea, and restless legs syndrome, which can interfere with the quality of your sleep.

The lowdown on low hormones
Hormones play a crucial role in regulating sleep patterns, and when these hormone levels fluctuate, it can impact sleep quality. The menstrual cycle involves significant hormonal changes, and understanding these dynamics can help improve sleep during this time.
The role of oestrogen and progesterone
Oestrogen and progesterone are the key hormones that fluctuate during the menstrual cycle, and they have opposing effects on sleep. Oestrogen, often referred to as E2, is the most active and abundant form of oestrogen. It is produced in the ovaries during reproductive years and plays a significant role in regulating the menstrual cycle. Oestrogen is known to help regulate the sleep cycle, and higher levels of oestrogen can lead to increased wakefulness and lighter sleep. Additionally, oestrogen fluctuations can disrupt serotonin production, a neurotransmitter that promotes sleep.
On the other hand, progesterone has a calming and sedating effect on the body. It rises during the second half of the menstrual cycle and can make you feel more tired. However, an excess of progesterone can lead to issues like snoring, sleep apnea, and restless leg syndrome, which can disrupt sleep quality.
Hormone fluctuations and sleep during the menstrual cycle
The menstrual cycle can be divided into several phases, each with unique hormonal dynamics that influence sleep.
Menstruation
During menstruation, oestrogen and progesterone levels are at their lowest, often resulting in fatigue and mood swings.
Follicular phase
As the body prepares to release an egg, oestrogen levels rise, leading to increased energy and motivation. However, this increase in oestrogen can also make it more challenging to fall asleep.
Ovulation
Ovulation is marked by a surge in oestrogen and a rise in progesterone. The sharp increase in oestrogen can cause sleep disturbances, such as insomnia.
Luteal phase
In the luteal phase, both oestrogen and progesterone levels are high, and this can lead to increased sleep disturbances and restlessness. The rise in progesterone can make it challenging to unwind and fall into a deep sleep.
Sleep issues during menstruation
Sleep problems during menstruation are common, with many people experiencing insomnia, fragmented sleep, or feeling unrested. These issues are attributed to hormonal fluctuations and changes in sleep architecture. Insomnia is particularly prevalent during the luteal phase due to rising progesterone levels. Additionally, symptoms like bloating, cramps, and mood swings can further disrupt sleep.
Other common sleep issues during menstruation include restless leg syndrome (RLS), characterised by an irresistible urge to move the legs, and sleep apnea, where breathing repeatedly stops and starts during sleep. The rise in progesterone can contribute to relaxed throat muscles, increasing the likelihood of airway obstruction and disrupted breathing patterns.
The importance of rest during menstruation
Sleep plays a crucial role in physical recovery, mood equilibrium, cognitive function, and energy conservation during menstruation. Prioritising quality sleep can make a significant difference in overall well-being during this time.

The progesterone slumber
The menstrual cycle is an intricate hormonal rollercoaster, with hormone levels fluctuating throughout the month. These changes can have a significant impact on sleep patterns and overall energy levels. During the second half of the menstrual cycle, hormone levels tend to drop, causing a spike in body temperature which can disrupt the body's internal clock and lead to sleep disturbances.
Progesterone, a natural sleep promoter, plays a crucial role in this process. During the luteal phase, progesterone levels rise, inducing a sedative effect that can make you feel more tired. However, as your period approaches, progesterone levels start to drop, making it more challenging to fall and stay asleep. This decline in progesterone can leave you feeling drained and struggling to unwind before bed.
Progesterone's calming effect on the body can promote sleep, but an excess can lead to issues such as snoring, sleep apnea, and restless leg syndrome, all of which can disrupt sleep quality. Therefore, understanding the dynamics of this hormone can help you implement strategies to improve your sleep during your period.
Navigating the menstrual cycle
The menstrual cycle consists of several phases, each with its unique impact on sleep. During menstruation, when oestrogen and progesterone levels are at their lowest, you may experience fatigue and lethargy. The follicular phase brings rising oestrogen levels, which can improve sleep quality. Ovulation is marked by a surge in oestrogen and a rise in progesterone, which can cause sleep disturbances. Finally, the luteal phase, with its high levels of both hormones, can lead to increased sleep disturbances and restlessness.
Strategies for better sleep during your period
To optimise sleep during your period, it's essential to understand the different phases of your menstrual cycle and their effects on sleep. Here are some tips to improve your sleep during each phase:
- Menstruation: Create a relaxing bedtime routine, use heat therapy to relieve cramps, and maintain good sleep hygiene by keeping your bedroom cool, dark, and quiet.
- Follicular phase: Engage in moderate-intensity exercise, maintain a consistent sleep schedule, and limit caffeine and alcohol consumption.
- Ovulation: Practice relaxation techniques, use blackout curtains or an eye mask to block out light, and try sleep-inducing herbal teas.
- Luteal phase: Limit exposure to blue light from electronic devices, practice stress management techniques, and invest in comfortable sleepwear to regulate body temperature.
The importance of rest
Sleep is crucial for physical recovery, mood equilibrium, cognitive function, and energy conservation during your period. Prioritising quality sleep can make a significant difference in how you feel and function during this time of the month.

The alertness of oestrogen
Oestrogen is one of the hormones that fluctuate during the menstrual cycle, and these hormonal changes can have a significant impact on sleep patterns and quality. Oestrogen is known to help regulate the sleep cycle, and lower oestrogen levels during the menstrual cycle can make women less resilient to stress and more susceptible to sleep disturbances.
Oestrogen levels are at their lowest during menstruation, which can lead to feelings of fatigue and lethargy. As the body progresses through the follicular phase, oestrogen levels begin to rise, leading to increased energy levels. This rise in oestrogen can cause sleep disturbances such as insomnia or difficulty staying asleep during ovulation. Oestrogen is also associated with increased wakefulness and lighter sleep, making it harder to achieve deep, restorative sleep.
During the luteal phase, both oestrogen and progesterone levels are typically at their highest. Progesterone has a sedating effect, which can make women feel more tired. However, it can also contribute to symptoms like restless leg syndrome or sleep apnea, which disrupt sleep quality.
The drop in oestrogen levels during menstruation can make women more susceptible to sleep disturbances, and some women report feeling more vigilant or even experiencing insomnia during this time. Therefore, it is essential to prioritise quality sleep and implement strategies to improve sleep during the menstrual cycle.

Common sleep issues during menstruation
Hormone fluctuations during menstruation can significantly impact sleep quality and duration. The menstrual cycle's hormonal rollercoaster affects sleep patterns, mood, and physiology. Here are some common sleep issues experienced by people during their period:
- Insomnia: This is a prevalent issue during the luteal phase, when rising progesterone levels cause restlessness and sleep disturbances. Bloating, cramps, and mood swings can further disrupt sleep.
- Restless Legs Syndrome (RLS) is characterised by an irresistible urge to move the legs, often with uncomfortable sensations. This makes it challenging to relax and fall asleep, leading to sleep deprivation and daytime fatigue.
- Sleep apnea is more common during menstruation due to hormonal changes, particularly the rise in progesterone, which relaxes throat muscles and increases the risk of airway obstruction.
- Disturbed sleep is common in the days leading up to and during the period due to declining oestrogen and progesterone levels. This can cause trouble falling and staying asleep.
- Sleep quality is often affected, with people feeling unrested despite sufficient sleep.
These issues arise from hormonal fluctuations and changes in sleep architecture during menstruation. Understanding these dynamics can help implement strategies for better sleep.
