How Brain Fog Is Connected To Poor Sleep

Many of us have experienced the frustrating feeling of brain fog. It's that state where we feel like we're not operating at our best, mentally. I first started noticing this during a particularly demanding time in my life - juggling a career, young children, and a never-ending to-do list. Unfortunately, these pressures often lead to a lack of quality sleep, with late nights spent trying to catch up or worrying about the day ahead. This vicious cycle can take a toll on our mental performance, leaving us with the dreaded brain fog.

Although not technically a medical condition, brain fog is a term that many people use to describe a range of cognitive symptoms that can affect their daily lives. It's characterized by a combination of cognitive fatigue, problems with judgment, and impairment in memory function. These symptoms can lead to issues with organizing daily schedules, mental confusion, and a lack of concentration, making even the simplest tasks feel difficult.

Deep Sleep and Brain Function

It's important to understand the connection between sleep and brain function. Our brains need deep cycle sleep to function optimally. During deep cycle sleep, our brains consolidate memories, clear out waste products, and recharge for the day ahead. If we're not getting enough, our brains simply can't function at their best. When you get enough deep-cycle sleep, you wake up feeling refreshed, allowing you to stay sharp and productive throughout the day. 

Increased GABA Supports Deep Sleep

Supporting your sleep and your ability to focus during the day is critically important. First Person's Moonlight has been formulated to boost deep-cycle sleep by promoting the body's natural production of GABA*. GABA is an inhibitory neurotransmitter that blocks or inhibits specific brain signals and decreases activity in your nervous system. At night, an increase in GABA production can help to further calm brain activity, allowing us to enter deeper sleep. GABA also prevents wakefulness during the night by suppressing brain activity, allowing us to stay asleep longer. By regulating brain activity and promoting relaxation, GABA is critical in achieving deep-cycle sleep.
