Menopause and Sleep

I know only too well that the peri-menopausal decline of oestrogen contributes to disrupted sleep. Menopausal hot flushes and sweats (vasomotor symptoms) contribute to night-time waking as does anxiety and a depressed mood. Anxiety can lead to difficulty getting to sleep and depression contributes to non-restorative sleep and early morning waking.

Sleep is essential for health and our sleep/wake cycle and is managed by the circadian clock in the brain. This is where my expertise expires and so I hand over to Dr. Joshua Rosenthal; a Board Certified Sleep Specialist. Dr Rosenthal is dedicated to holistic health and wellness and he translates some challenging biological science into accessible health interventions.

Light and Hormones

The eye connects to the brain clock and the Hypothalamic Pituitary Adrenal axis HPA, which controls all hormones. Light talks to the pituitary gland which talks to adrenals and influences the production and balance of all hormones including oestrogen, vitamin D and Melatonin.

Melatonin is the hormone responsible for sleep signalling and it is made in the retina on exposure to natural light wavelengths which occur at sunrise. The blue light wavelengths suppress the production of melatonin as does mobile phone EMF radiation. So melatonin is made in the sun but the effects are activated at night for restful sleep.

Blue light Hazard!

Any light in the wavelength range 4-500nm equates to a blue light hazard. This blue light isn’t just responsible for suppressing melatonin but can create reactive oxygen species or free radicals which are responsible for raised levels of inflammation. Inflammation is the precursor for most diseases. Reducing blue light exposure can reduce inflammatory markers in the body.
