In brief:

  1. Up to 60% of women report sleep disturbances during menopause.
  2. Melatonin shortens sleep onset time by an average of 7-8 minutes, according to studies.
  3. Adults need 7 to 9 hours of sleep per night for optimal recovery.

Understanding sleep problems in women

Sleep disturbances are more common in women than in men, with hormonal fluctuations as one of the main factors. The menstrual cycle, pregnancy and menopause all affect sleep architecture in different ways.

Menopause as a critical phase

Declining progesterone levels during menopause are considered one of the main causes of nighttime waking and reduced sleep quality.

The role of melatonin

Melatonin is the key hormone regulating the sleep-wake cycle and is increasingly used as a supplement.

Effects in detail

  • Shortens sleep onset time by an average of 7-8 minutes
  • Works especially well for irregular sleep schedules or jet lag
  • Shows little effect when sleep quality is already normal

Factors influencing sleep quality

What the research shows

“A regular sleep-wake rhythm is one of the strongest predictors of good sleep quality, regardless of supplement use.” — Sleep Medicine Reviews

Practical steps for better nights

  1. Keep consistent sleep and wake times, including on weekends
  2. Avoid screens for at least one hour before sleep
  3. Limit caffeine intake to the morning

Good sleep is closely linked to a strong immune system and a stable metabolism, and it visibly affects skin and hair as well.

Frequently asked questions

Why do many women struggle to fall asleep?

Hormonal fluctuations, particularly around the menstrual cycle, pregnancy and menopause, directly affect sleep architecture. Studies show up to 60% of women report sleep disturbances during menopause, mainly due to declining progesterone levels.

How does melatonin affect sleep quality?

Melatonin regulates the circadian rhythm and can shorten sleep onset time by an average of 7-8 minutes, according to a meta-analysis of several clinical studies. The effect is strongest for irregular sleep schedules or jet lag.

How many hours of sleep does an adult woman need?

Most adults need 7 to 9 hours of sleep per night for optimal physical and cognitive recovery. Regularly sleeping less than 6 hours is linked to a higher risk of metabolic and immune problems.
