Melatonin is a hormone primarily known for its role in regulating the body's circadian rhythm, its sleep-wake cycles, which help to regulate sleep patterns. Produced by the pineal gland in the brain, melatonin also plays an important role in women's health.
Melatonin levels fluctuate throughout the menstrual cycle, which may impact sleep quality. During the follicular phase, melatonin levels are relatively low. However, during the luteal phase, which occurs after ovulation, melatonin levels increase.
Melatonin's role in regulating sleep is particularly relevant for women experiencing sleep disturbances, such as insomnia or disrupted sleep patterns. It can be especially impactful during perimenopause and menopause when oestrogen and progesterone fluctuations can lead to sleep disturbances. Melatonin supplementation or optimising natural melatonin production can help improve sleep quality and promote better overall well-being.
Beyond sleep regulation, melatonin has been for its potential effects on reproductive health. Melatonin has antioxidant properties, which can help protect the eggs and reproductive tissues from oxidative stress. It has also been to have a protective role in maintaining the health of the placenta during pregnancy.
Melatonin may also play a role in breast health. Studies show that melatonin may help reduce the risk of breast cancer. Additionally, melatonin's antioxidant properties may help protect breast tissue from damage.
