Have you ever found yourself lying awake at night, heart pounding in your chest, a cold sweat forming on your brow, feeling utterly alone in your experience? You’re not alone. Countless women across the globe are grappling with the same unsettling sensations, searching for answers and relief.
These heart palpitations, often linked to menopause, can be both disconcerting and isolating. But understanding the intricate connection between our heart’s rhythms and our body’s hormonal changes can offer not just clarity, but also a shared sense of community and hope.
Estrogen isn’t just a mere hormone in our bodies. It plays an instrumental role in numerous processes, and we have estrogen receptors dispersed throughout our entire body. Certain parts of our brain are especially rich in these receptors. But why does that matter?
Our sex hormones, which include estrogen, progesterone, and testosterone, are closely intertwined with neurotransmitters such as serotonin, dopamine, GABA, and neuroppeptides called endorphins. These connections are pivotal when it comes to our overall well-being.
As women approach menopause, estrogen levels begin to decline. This decline, particularly in estrogen, affects serotonin and endorphin levels. When serotonin and endorphin levels drop, our bodies trigger a compensatory reaction that leads to an increase in norepinephrine, a stress hormone akin to adrenaline.
When norepinephrine levels surge, our fight or flight system—a primal response mechanism—kicks in. Imagine this: your brain believes you’re evading a bear. In response, it vasodilates your blood vessels, enhancing blood flow to the heart. This sudden increase leads to a dispersion of heat, causing the infamous hot flash. Concurrently, your breathing rate and heart rate elevate, which can lead to the heart palpitations and chest flutters many women report.
Ever been jolted awake in the middle of the night, heart pounding, drenched in sweat, and teetering on the brink of a panic attack? It’s not just a night-time scare; it’s a physiological response. The drop in serotonin affects our limbic system—a crucial part of our brain responsible for mood, emotion, appetite, pain, sex drive, and sleep. This drop can lead to sleep disruptions, and it also triggers the release of more norepinephrine, spiraling into the same physiological reactions we experience when faced with intense stress.
