Brain Fog Isn’t Just Aging: How to Sharpen Focus Through Nutrition and Daily Habits
Although becoming increasingly common, brain fog is not a technical diagnosis. Rather, it is a collection of symptoms where an individual experiences feeling cognitively fatigued and clouded because their neurotransmitters are not firing optimally.
Brain fog does not discriminate, manifesting differently and situationally across men and women of all ages, including women navigating perimenopause and menopause, busy professionals, athletes, parents, people with anxiety and depression, individuals with Long COVID and people with compounded lack of sleep.
Vail Healthspan medical director Dr. Barry Sandler says brain fog should not be dismissed as simply aging. Modern lifestyles place significant stress on our brains and nervous system: poor sleep, chronic stress, excessive screen time, alcohol, hormonal changes, overtraining, burnout and sedentary behavior.
“In Healthspan medicine, we view brain fog as an early warning sign that the brain and body may not be recovering or functioning optimally,” Sandler says.
Christine Pierangeli, Vail Healthspan nutritionist, says brain fog is a multifactorial issue with a common denominator: inflammation.
“Chronic inflammation affects our neurotransmitters, our mood, our mitochondrial and brain signaling,” Pierangeli explains. “That is where diet quality, gut health, movement and sleep can help quell the inflammation.”
Common Signs of Brain Fog
- Forgetfulness
- Fatigue or low energy
- Difficulty concentrating
- Word-finding difficulties
- Reduced motivation
- Feeling “checked out” or mentally disengaged
- Slower processing speed
- Irritability
- Difficulty multitasking
Reactionary Exhaustion
Individuals can experience brain fog for minutes, hours, days or chronically. Sometimes all someone needs is a nutritious meal or a quality night of sleep. Other times, unfortunately, brain fog is a perpetual state.
If our nervous system is constantly in fight or flight, our bodies become exhausted and inflamed, leading to prolonged periods of brain fog. Pierangeli explains this as reactionary exhaustion: “the fatigue we have from constantly reacting to our world.”
If you have gotten accustomed to reactionary exhaustion, or brain fog, you don’t have to.
The Three Pillars
There are three main pillars to improve brain fog: stress management sleep and nutrition. Enhancing cognitive clarity begins with consistent, nourishing whole-body habits that manifest overtime.
“We have to think of ourselves as a whole system,” Pierangeli declares. “Slow and steady creates sustainable progress.”
Prioritize these pillars in your life to prioritize your mental clarity.
Stress originates and looks different in everyone. At the end of the day, when you are stressed, the neurotransmitters in your brain cannot perform to the best of their ability, leading you to feel brain fog. Stress management looks different for everyone, but the first step is recognizing that it is a priority. Providers at Vail Health, Vail Healthspan and Vail Health Behavioral Health are great resources.
Sleep is when we clear our brains because “sleep consolidates our memories, clears metabolic waste and regulates our mood,” Pierangeli says. “One night of bad sleep can impact our decision making and focus, which over time, accumulates.” Sandler and Pierangeli recommend waking up and falling asleep at the same time every day, even on the weekends, to optimize your circadian rhythm.
Nutrition is your way to heal your brain fog from the inside out. It is crucial to prioritize whole foods at every meal. Pierangeli recommends omega-3 fatty acids, colorful plants, fiber and protein.
Foods for Brain Health
- Omega-3 fatty acids support the brain’s cell membrane, restoring neurotransmitter signaling and inflammation regulation. Fatty fish are the best way to add these brain-boosting powerhouses to your diet: salmon, mackerel, anchovies, sardines and herring.
- Colorful plants such as berries and leafy greens are filled with antioxidants and polyphenols, protect your cells from oxidative stress and support vascular health.
- Fibrous foods such as nuts, seeds, beans, berries and sweet potatoes help nourish your gut, also known as your “second brain.” A healthy gut is directly correlated to a healthy brain.
- Amino acids are the building blocks of protein. Whether you source your protein from animals, plants or both, the amino acids are necessary for brain function. The older we get, the more we need.
Improve Mental Clarity With Simple Recipes
These two recipes are packed with the nutrients our bodies need to feel our best, supporting blood sugar, satiety, inflammation and, of course, brain balance. The ingredients below provide a foundation for the recipes. Measurements can be scaled depending on your goals, serving size and personal preference.
Brain Boosting Salmon Bowl
- Wild Salmon or canned salmon
- Quinoa or brown rice
- Arugula or baby greens
- Roasted sweet potato

Antioxidant Smoothie
- Blueberries
- Spinach
- Ground flax or chia seeds
- Unsweetened Greek yogurt or dairy-free protein option
- Almond milk
- Cinnamon
- Optional: avocado for creaminess
Improve Brain Fog With Movement
- 10-minute walks after meals balance blood sugar.
- Regular zone 2 aerobic exercise improves blood flow.
- Lift weights 2-4 days a week. Muscle plays an important role in metabolic health.
- Short movement breaks during sedentary work improve circulation and reduce mental fatigue.
- Walking outdoors, especially in natural environments, reduces stress and improves attention.
Improve Brain Fog With Restorative Habits
- Prioritize seven to nine hours of high-quality sleep.
- Limit alcohol.
- Avoid overtraining and build recovery into daily life. Including rest days, stretching, mobility work and time away from screens.
- Stay hydrated.
- Box breathing. Inhale for four seconds, hold for four seconds, exhale for four seconds and hold for four seconds.
- Spend time in the sunlight to improve nervous system regulation.
The brain is one of the most metabolically active organs in the body. When you prioritize cognitive health and nutrition, you are adding life to your years while advancing your cognitive vitality, resilience, relationships and quality of life.
