Our modern lives – with computers, TV, texting, tweeting, emails and cell phone calls all going at once – can overstimulate the brain and increase stress levels.“Our brains can only hold one thought at a time,” Dr. Pasinski says. Constant interruptions disrupt our ability to focus, concentrate and retain information.Try it: Nature has a calming effect. So walk in the park, take the scenic route, stop to watch the sunset or just gaze at evening stars.Spending time in green spaces lessens brain fatigue, according to a 2013 study published in The British Journal of Sports Medicine. Researchers compared brain wave patterns of participants who took a 25-minute walk through urban areas, versus another group who strolled through a leafy park. They found that the city walkers became frustrated, while the park walkers were mentally quieter and meditative.
“The beauty of nature will give your prefrontal cortex – the area of your brain that helps you focus – an opportunity to recharge,” Dr. Pasinski says.
Relaxing activities such as yoga, tai chi, qigong and meditation can improve problems with sleep, fatigue, poor memory and anxiety – all of which are linked to brain fog, according to many studies.
For example, 20 volunteers with fibromyalgia saw improvements in sleep, pain, and physical and mental functioning after practicing qigong for eight weeks, according to a 2013 Canadian study published in the journal Evidence-Based Complementary and Alternative Medicine.
And those who practiced the most had the best outcomes, the researchers said.
Try it: Sign up for classes at your local gym or YWCA or rent instructional DVDs from the library.
If possible, practice outside, advises Dr. Teitelbaum. “The combination of exercise with sunshine and fresh air can help reduce brain fog.”
These 5-minute meditations may help too.
