Executive function (EF) is the brain’s management system, governing focus, planning and emotional regulation. While occasional lapses are normal, many people—especially those with ADHD or other neurodivergent traits—experience ongoing challenges often called “executive dysfunction.” Developmental psychologist Stephanie M. Carlson, PhD, senior science advisor at Reflection Sciences, explains that EF is the brain basis for self‑control and is essential for everyday tasks.
1. Improve Indoor Air Quality
A study published in Scientific Reports found that adults aged 40 and older who lived in high‑traffic, polluted areas performed 12% faster on EF and mental‑flexibility tests after using a high‑efficiency particulate air (HEPA) purifier for one month. By removing dust, dirt and smoke particles, HEPA filters create cleaner indoor air that protects the brain from cognitive harms linked to pollution. Carlson notes that anything influencing brain health, including air quality, can affect EF. Placing a purifier in the room you spend the most time in is a simple first step.
2. Try Body Doubling
Body doubling means working alongside another person to boost focus. For individuals with ADHD, the presence of a partner can reduce task paralysis—the feeling of overwhelm that stalls progress. While research is still emerging, early findings suggest that having someone nearby to lean on, ask for help, or simply share space can lower stress, raise self‑esteem and improve attention. Body doubling can be as informal as a parent sitting with a child during homework, or as structured as virtual co‑working platforms like Focusmate or Flow Club. Even “study‑with‑me” videos on YouTube can provide the needed accountability.
3. Wear “Home Shoes” to Signal Work Mode
Wearing shoes inside the house can cue the brain that it’s time to work, a concept rooted in “enclothed cognition”—the idea that clothing influences thoughts and behavior. Switching from lounge wear to indoor‑only shoes or slippers when you need to focus creates a mental shift from relaxation to task mode. The same effect can be achieved by changing into work‑appropriate clothing, even if you stay at home.
4. Use White, Pink, or Brown Noise
Background sounds such as white, pink or brown noise can mask distracting noises and provide a steady auditory environment. White noise resembles static or a fan, pink noise mimics light rain or rustling leaves, and brown noise sounds like ocean waves or a distant train. A meta‑analysis in the Journal of the American Academy of Child and Adolescent Psychiatry reported modest improvements in task completion for children, teens and college‑age adults with ADHD when listening to white or pink noise. While research on brown noise is limited, many users find it helpful for sleep, which also supports EF.
5. Consider Cold Therapy
Cold exposure—such as a brisk morning shower or a brief cold plunge—may help regulate the nervous system and boost alertness. One self‑report study indicated participants felt more focused after regular cold‑therapy sessions. Though the evidence is preliminary, incorporating a short, cold burst into your routine could be a low‑risk way to stimulate the brain.
Putting It All Together
Improving executive function does not require a single miracle solution. By combining practical steps—cleaner indoor air, supportive work companions, intentional clothing cues, calming background sounds, and occasional cold exposure—families and individuals can create an environment that nurtures focus, planning and emotional balance. As Carlson emphasizes, “Anything that affects brain health, including air pollution, is likely to affect EF.” Experiment with these strategies to discover which combination works best for your household or workplace.
