Why Does Menopause Cause Brain Fog, and What Can You Do About It?

Kale Amato

Menopause can feel like your body hit the reset button without asking permission. Alongside hot flashes, sleep changes, and shifting hormones, many women notice another common experience: brain fog. If you’ve walked into a room and forgotten why, lost your train of thought mid-sentence, or felt mentally drained by small tasks, you’re not alone.

October is Menopause Awareness Month. In this overview, you’ll learn what menopause brain fog is, why it happens, and simple, science-informed ways to support clarity, focus, and steadiness during this transition.

What Is “Menopause Brain Fog”?

“Brain fog” refers to a cluster of experiences such as difficulty concentrating, forgetfulness, and mental fatigue. These shifts are not signs of decline; they are commonly associated with hormone changes—especially a drop in estrogen—which plays a role in attention, memory, and emotional regulation.

The Science Behind the Fog

Hormones and the Brain

As estrogen levels change, it can influence brain chemicals involved in learning and memory. Temporary lapses in focus and recall are common during this time and often improve as your body adapts.

Gamma Brain Rhythms (~40 Hz)

Research highlights the role of gamma brain rhythms—particularly around 40 Hz—often associated with attention and memory. During menopause, shifting hormones and sleep patterns may influence these rhythms, which can contribute to that “cloudy” feeling. Early studies are exploring whether gentle exposure to rhythmic 40 Hz light may help the brain maintain healthy activity patterns linked with focus and learning.

Sleep Rhythms

Night sweats and schedule changes can fragment sleep, which may affect working memory and attention the next day. Supporting consistent sleep habits—wind-down routines, cooler room temperatures, and lower evening screen time—can contribute to clearer mornings.

Self-Care for Menopause Brain Fog

  • Prioritize Sleep: Aim for a steady bedtime, a calm wind-down, and reduced blue-light exposure in the evening.
  • Eat for Brain Support: Build meals around leafy greens, berries, omega-3s, and fiber-rich foods.
  • Move Daily: Gentle activity—walking, yoga, light strength—can support mood and mental clarity.
  • Practice Mindfulness: Even 5–10 minutes of breathwork or meditation may help settle racing thoughts.
  • Nurture Natural Brain Rhythms: Some people add a short daily session with gentle 40 Hz light as part of their routine to help maintain calm, focused states.

Where Does BEACON40® Fit?

BEACON40® emits gentle, flickering 40 Hz light designed for everyday wellness routines. Place it in your peripheral vision while you read, work, or relax. While not a medical device, early research into rhythmic 40 Hz light suggests it may help the brain maintain balanced activity and healthy sleep-wake patterns. Many users incorporate BEACON40® to support memory, focus, and a steadier wind-down—without disrupting their day.
