Navigating through the monthly ebb and flow of your menstrual cycle can feel like a herculean task when fatigue kicks in and it often comes with a side serving of sleep disturbances. But why does this happen, and is hitting the snooze button a few more times really the antidote you need during your period?
Understanding the intrinsic link between your hormonal ballet and sleep may illuminate why you feel more worn out during those days of the month and reinforce the importance of restful slumber for your overall well-being.
The menstrual cycle isn't just a reproductive highlight reel—it's an intricate hormonal roller coaster affecting virtually every aspect of your physiology, mood, and yes, sleep patterns.
During menstruation, hormone levels fluctuate significantly; oestrogen and progesterone dip to their lowest post-ovulation, leading to a kaleidoscope of physical and emotional changes including fatigue and mood swings.
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.
During ovulation, the sharp increase in oestrogen levels can cause sleep disturbances such as insomnia or difficulty staying asleep.
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.
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.
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.
There’s actually three different types of oestrogen, but we’ll focus on E2. This is the most active and abundant form of oestrogen and generally the one people are talking about when they refer to it. This hormone is made in the ovary during our reproductive years (after puberty and before menopause) and plays a big role in regulating our menstrual cycle.
Oestrogen, known for its role in sexual development and reproductive function, also 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. Furthermore, fluctuations in oestrogen levels can 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. Understanding these hormonal dynamics can help you implement strategies to improve your sleep during your period.
Sleep problems during menstruation are not uncommon. Many people experience symptoms such as insomnia, fragmented sleep, or feeling unrested despite getting enough hours of sleep. These issues can be attributed to the hormonal fluctuations and changes in sleep architecture that occur during this time of the month.
Insomnia, characterised by difficulty falling asleep or staying asleep, can be particularly prevalent during the luteal phase of the menstrual cycle. The rise in progesterone levels can contribute to increased sleep disturbances and restlessness. Additionally, symptoms like bloating, cramps, and mood swings can also disrupt sleep, further exacerbating the problem.
Restless legs syndrome (RLS) is another common sleep issue experienced by people during their period. RLS is characterised by an irresistible urge to move the legs, often accompanied by uncomfortable sensations. This can make it challenging to relax and fall asleep, leading to sleep deprivation and daytime fatigue.
Sleep apnea, a condition where breathing repeatedly stops and starts during sleep, can also be more prevalent during menstruation. The hormonal changes, particularly the rise in progesterone levels, can contribute to the relaxation of muscles in the throat, increasing the likelihood of airway obstruction and disrupted breathing patterns.
Sleep isn't just a time-out from daily life—it's when your body launches its repair and recovery processes. Given the additional physical and emotional demands during menstruation, it's plausible and, indeed, advisable to be attentive to your body’s need for rest:
While you may not need to sleep for hours on end, prioritising quality sleep can make a world of difference. Here are some tips:
Getting a good night's sleep during your period starts with understanding the different phases of your menstrual cycle and how they impact your sleep patterns. By tailoring your sleep routine to each phase, you can optimise your rest and wake up feeling refreshed and rejuvenated.
During this phase, oestrogen and progesterone levels are at their lowest, which can lead to feelings of fatigue and lethargy. To promote better sleep during menstruation, try the following tips:
As your body prepares to release an egg, oestrogen levels begin to rise during the follicular phase. This increase in oestrogen can have a positive impact on your sleep quality. To maximise the benefits, try the following tips:
Ovulation occurs when an egg is released from the ovary. This phase is characterised by a surge in oestrogen and a rise in progesterone levels. To optimise your sleep during ovulation, consider the following tips:
The luteal phase is the final phase of the menstrual cycle before menstruation begins again. During this phase, both oestrogen and progesterone levels are at their highest, which can lead to sleep disturbances. To combat these disturbances, try the following tips:
By understanding the unique sleep challenges and opportunities presented by each phase of your menstrual cycle, you can adopt strategies tailored to your specific needs, ensuring a better night's sleep throughout the month.
If you find yourself reaching for the alarm clock with growing frequency during your period, it's not just a frivolous luxury—it's your body advocating for the restorative sleep it needs. Listening and responding to this biological cue isn’t a sign of weakness; it's about empowering yourself with the rest required to face your days with vigour, regardless of the time of the month.
During menstruation, don't ignore the symbiotic relationship between sleep and your hormonal health. Grant yourself permission to rest as an act of self-care, and remember, in the great symphony of your menstrual cycle, sleep isn’t just an interlude—it's a necessary rest note.
