Have you ever tried brushing your teeth with your non-dominant hand? It might sound strange, but some experts believe that it could help clear up brain fog and improve how our brains work. Content creator and NHS doctor Dr Karan Rajan explains in his reel, “If you start brushing your teeth with your non-dominant hand, you probably will build some new neuronal connections in your brain.” Brain fog makes you feel fuzzy and unable to think clearly. It can happen when you're stressed, tired, or just not feeling your best. But could something as simple as using your other hand to brush your teeth really make a difference? View this post on Instagram A post shared by Dr Karan Rajan (MRCS MBBS BSc) (@drkaranrajan) Neha Cadabam, senior psychologist and executive director at Cadabams Hospitals says, “There's currently limited scientific evidence directly linking brushing teeth with the non-dominant hand to improved cognitive function or reduced brain fog. Brain fog is a subjective experience, and research on its causes and solutions is ongoing.” However, she adds, studies suggest that stimulating the brain through novel activities can enhance cognitive function. Brushing with your non-dominant hand might provide a small degree of cognitive challenge. Potential neurological mechanisms that might positively impact brain regulation or cognitive clarity Cadabam informs, “The theory behind this practice lies in neuroplasticity, the brain's ability to adapt and form new neural connections. Using the non-dominant hand forces the brain to engage different neural pathways to perform a familiar task." This increased activity could potentially strengthen existing connections and create new ones, possibly leading to sharper cognitive function. However, she confirms that more research is needed to understand the specific neural mechanisms at play. Could regularly engaging in activities that challenge the non-dominant hand potentially lead to long-term cognitive benefits? While there's limited evidence for immediate brain fog relief, using the non-dominant hand for daily tasks might offer some long-term benefits. “Regularly engaging in activities that challenge your motor skills can potentially stimulate neuroplasticity, the brain's ability to adapt and form new connections,” remarks Cadabam. This could lead to improved cognitive reserve, the brain's resilience to decline as we age. However, the observed effects might be subtle and require consistent practice over a prolonged period. Lifestyle factors or interventions recommended to promote cognitive health and clarity According to Cadabam, the following lifestyle changes can be made to improve cognitive health and clarity: Exercise: Regular physical activity has been shown to improve cognitive function by increasing blood flow to the brain and promoting neurogenesis (growth of new brain cells). Mindfulness and Meditation: These practices enhance focus and concentration, potentially reducing feelings of mental fog. Cognitive Training: Games and exercises designed to challenge memory, attention, and processing speed can improve cognitive performance. Sleep Hygiene: Prioritising quality sleep allows the brain to consolidate memories and clear waste products, promoting cognitive clarity. Balanced Diet: Maintaining a healthy diet rich in fruits, vegetables, and omega-3 fatty acids provides essential nutrients that support brain function.
