Like many women, I am all too familiar with the middle-of-the-night wake-up. One minute I’m fast asleep, the next I’m up like a meerkat in fully-awake, hyper-vigilant mode. I have always been jealous of my husband who can be woken up by a small child or car alarm at 3am and almost immediately fall back asleep – instead I’ll lie there working through my worry list for hours.
I’m not at all suggesting 3am wake-ups are something only women experience, but it certainly seems to be a popular topic of discussion among my female friends. And this is backed up by the stats – GP Dr Nisa Aslam, advisor to Evera Nutrition, says ‘If you regularly find yourself waking up at 3am and struggle to get back to sleep, you’re not alone. Research suggests women are 25% more prone to this and 1.5-2 times more likely to suffer from insomnia than men.’
Hormonal fluctuations across the menstrual cycle and during menopause appear to play a major role. ‘Shifts in key hormones such as oestrogen and progesterone can affect sleep depth and body temperature making early-morning waking more likely,’ says Aslam. ‘Moreover, sleep naturally becomes lighter in the second half of the night, which means even small disturbance can trigger waking.’
Key times for sleep disturbance in women include…
Around your period
‘During the menstrual cycle, hormone levels rise and fall and can influence sleep quality. In the first half of the cycle, oestrogen gradually increases. This hormone supports brain function, mood and sleep regulation, and many women report relatively stable sleep during this phase. After ovulation, progesterone rises. Progesterone has mild sedative properties and can promote sleepiness by acting on calming brain receptors. However, in the days before a period, both progesterone and oestrogen drop sharply which can lead to lighter sleep, more nighttime awakenings and a lower threshold for waking in the early hours. Many women dramatically notice this in the premenstrual phase, when restlessness, headaches or racing thoughts can coincide with disrupted sleep.’
During perimenopause
‘The 3am wake-up becomes even more common during the transitional stage leading up to menopause when oestrogen levels fluctuate unpredictably and progesterone gradually declines. These shifts can interfere with the brain’s sleep regulation systems and the body’s internal clock. One major trigger is night sweats or hot flushes, which can cause sudden awakenings in the early hours. Even if these pass quickly, it may be difficult to fall back asleep once the brain becomes more alert.’
After menopause
‘Here, hormone levels stabilise at lower levels, but sleep patterns often remain altered and may affect the brain’s temperature regulation and circadian rhythm, which can lead to lighter sleep and a natural earlier morning waking window. At this stage, factors such as stress, ageing sleep patterns and lifestyle habits may also contribute to the 3am wake-up.’
Why do we wake up at 3am specifically?
According to Aslam, ‘The early morning hours are when the body transitions into lighter sleep and cortisol begins to rise in preparation for waking. Blood sugar levels may also dip slightly overnight.’
What can help
While hormonal changes are a natural part of life, supporting sleep habits can help reduce the chances of early waking. Aslam suggests you try:
Keeping a consistent sleep schedule. This helps regulate your circadian rhythm, the body’s internal clock that controls when you feel sleepy and alert.
Eating a balanced early evening meal may help keep blood sugar levels more stable through the night. If blood glucose drops too low overnight, the body releases stress hormones such as cortisol and adrenaline to raise it again which can trigger alertness, making it difficult to stay asleep.
**Supporting sleep with nutrients and botanicals. **Nutritional status may also influence sleep quality and resilience to stress. Data suggests that nutrient insufficiency remains common among women with vitamin D levels below recommended thresholds, while a significant proportion have suboptimal folate status as well as inadequate magnesium intake. These nutrients are involved in pathways linked to sleep and nervous system regulation. Sleep-support formulations such as Evera Nutrition Deep Sleep combine these nutrients alongside calming botanicals and L-theanine. Nutrient deficiencies are a key cause of sleep issues as they do reduce the body’s ability to maintain stable sleep and hence addressing nutrient deficiencies is essential.
Avoiding alcohol late in the evening. While alcohol may help you fall asleep faster, it tends to suppress deep sleep early in the night and increase awakenings the early-morning hours.
Managing stress levels before bedtime A calming wind-down routine before bed can help signal to the brain that it is time to sleep. Gentle stretching, reading, meditation or breathing exercises may help reduce stress levels and prepare the body for rest.
And if you do wake at 3am? ‘Try not checking the clock, as this can increase stress and make it harder to fall back asleep,’ advises Aslam. ‘Instead, focus on slow breathing and relaxation – giving your body the best chance to drift back into restorative rest. Occasional night waking is normal, and resting quietly can still be restorative, even if you don’t fall back asleep straight away. Keeping the body relaxed and avoiding stress about sleep often makes it easier to drift off again.’
