While there is no definitive number of hours proven to be the best for humans, it is suggested by most experts that a minimum of 7 hours of uninterrupted sleep be observed by most. Care should be taken to remove any barriers to achieving and maintaining sleep from the bedroom (i.e. TVs, computers, excess light, poor quality/old beds, etc.). Among other things, memories are formed when we sleep and improved quality and duration of sleep can stave off cognitive decline due to aging.
Stress, namely the long-term continuous stressors many of us face on a day to day basis (e.g. jobs, relationships, traffic, finances, etc.), and the ill-effects it brings on are touted as the root cause of the majority of chronic diseases of our modern society. There are countless techniques available to us to help us manage stress including meditation, journaling, counseling, prayer, yoga, NLP, Tai Chi, etc., and they all have their distinct advantages with regard to helping our brains perform better. The majority of the research on stress reduction and the brain has been done in the area of meditation.
We all know we should do it and we need to ‘Make the Time’ instead of trying to ‘Find the Time’. The evidence is irrefutable, exercise makes your brain work better…period! From increased blood flow carrying oxygen and nutrients to our ‘Greedy Master’, to production of chemicals that help us connect nerve cells and even grow new ones; we all need to exercise.
Notice the word water is capitalized! While the occasional naturally flavored drink of your choice is fine, water should be your main source of hydration as it will eliminate intake of sugars, sugar substitutes, artificial flavors/colors, etc. that can all be harmful to your brain. Our bodies are made up of roughly 60% water content and our brains are even higher at upwards of 80%.
Another area where our brain requires more, and the right kind of, raw materials is fat consumption. Under normal circumstances our bodies are comprised 20-25% fat and our brains approximately 60%. While I am unable to get into the biochemistry of fats in this limited space, adhering to a few simple rules can help get you off to a good start. Avoid at all costs processed, man-made fats that fall under the general heading of ‘Trans Fats’. These are dangerous for our brains and bodies in so many ways, many of which we do not even know yet. Also, minimizing saturated fat intake is advisable for most (e.g. red meats, butters, etc.). Poly and monounsaturated fats found in whole food sources (nuts, vegetable oils, greens, etc.) and omega-3 fatty acids found in fish and other whole food sources are desirable for a better brain.
Exercise for your brain! Learning new subjects, skills and hobbies can help to preserve and build your brain’s resources to ensure it functions at its highest ability as we move through this journey of life. Novel stimulation has been shown to enhance brain activity immeasurably; whereas routine, monotonous type behaviors will likely ensure a slow, steady decline in cognitive function over time. Google ‘Learning and the Brain’ and sift through the 132 million results for some light reading to begin the process of learning and remember…We are NEVER too old to learn!
The benefits of REAL/WHOLE foods in our diets is endless, especially fruits and vegetables. They are low-calorie and loaded with vitamins, minerals, antioxidants, good sugars and fiber; which are all good for our brain. So many of our foods are far from their original source, so begin to learn (which is also good for your brain) about the dangers of processed and genetically modified foods and you will begin to develop an appreciation for fresh, whole foods that power your brain much more efficiently!
Much to my dismay this tip is often left off of many “Top 10” brain health lists and could quite possibly be one of the most important factors for a brain to be able to survive and thrive! Numerous studies over the past 100 years have shown how social isolation can cause significant psychological and neurological impairment, and even death in extreme cases. Social isolation disrupts myelin production, which is critical for nerve signaling and transmission. Volunteer, join a book club or service organization, take a class, walk the neighborhood and talk to your neighbors…put yourself out there – your brain will thank you!
Drinking, smoking, laziness, poor diet, worry, anger, sedentary behavior, dangerous physical activities, etc…
Our brain’s ‘reward system’ is intimately linked to our older emotional (limbic) brain on one end, and our newer cognitive (cortical) brain on the other. That said, to help balance and improve function in either of these regions, exercising our reward system is a critical step in the process. Further, the neurotransmitter dopamine is a key player in this system and it is increased with repetitive utilization of this system (this is the same neurotransmitter in short supply in conditions like Parkinson’s!). Goals must be realistic and attainable, but also strong enough to stretch our mental capacities for optimal benefit!
