Not only is exercise crucial for your overall physical and mental wellbeing, but it is also specifically important for maintaining an optimally functioning, healthy brain. Exercise increases the flow of nutrients, blood, and oxygen to the brain, helping to keep it in peak condition and improve your brain health.
Exercising regularly can also improve sleep, reduce stress, prevent high blood sugar levels, support healthy blood pressure, and boost mood – all of which help protect the brain from harm.
Aerobic activity, in particular, boosts brain function called neurogenesis, which is the process by which new neurons are formed in the brain . Neurogenesis helps protect against Alzheimer’s disease and cognitive decline while maintaining memory.
While any exercise is beneficial for brain health, these 5 activities are exceptional options for improving brain health and potentially staving off cognitive decline .
Swimming is one of the most intense aerobic exercises, involving all the major muscle groups, working the lungs and heart, and increasing blood flow to the brain. Additionally, the rhythmic motion and sound of your breathing during swimming are meditative and calming. Combined, these effects trigger the release of endorphins, hormones that elevate mood and decrease the perception of pain.
One study showed that 20 minutes of moderate-intensity swimming improved hand-eye coordination by 4% , while another study showed that 7 days of swimming exercise training (in rats) improved memory . A review of existing research also indicated positive effects of exercise (such as swimming) on task performance in children with ADHD .
A highly aerobic exercise requiring coordination, table tennis is one of the best brain-boosting exercises you can do. One Japanese study showed that ping-pong activates up to 5 different areas of the brain at the same time . In the study, table tennis players with brain disease displayed decreased signs of depression and dementia alongside improved awareness and brain function.
Another study showed that aerobic exercise such as playing table tennis increases the size of the front part of the hippocampus by 2%, leading to improvements in spatial memory function .
Additional research showed that table tennis exercise may improve the motor symptoms of patients with Parkinson’s Disease . After a 6-month regimen of weekly 5-hour exercise sessions, study participants showed improvements in balance, walking, getting out of bed, dressing, and speaking.
Many of these brain health benefits also apply to racquet sports outside of ping-pong, such as tennis, racquetball, and pickleball – activities that also have a low likelihood of causing brain injuries.
No longer just for powerlifters, strength training has been shown to have numerous physical and metal benefits, including :
- Improvements in brain function among older adults
- Reduced anxiety symptoms among healthy adults
- Improvements in self-esteem
- Reduced symptoms of depression
- Improved sleep quality among depressed older adults
- Reductions in pain intensity among patients with low back pain, fibromyalgia, or osteoarthritis
- Reduced symptoms of fatigue
Additionally, research has shown that resistance exercise leads to long-term brain benefits in people with mild cognitive impairment .
With a style for every person’s taste, yoga is becoming increasingly popular, and for good reason. In addition to being excellent for stress relief, a large review of studies showed that yoga has many benefits include: joint disorders, reduced risk of developing diabetes, improved immunity, lower BMI, reduced blood pressure, lower cardiovascular risk, and improved mental ability .
In fact, yoga seems to increase the volume of the hippocampus as well as aerobic exercise , making it an excellent option for people who can not handle harder activities. In a different study, participants in an 8-week yoga group showed significantly improved performance with mental flexibility and working memory compared to those who performed simple stretching techniques rather than a full yoga course .
Since dancing combines music, social bonding, and coordination, it activates multiple areas of the brain, boosting brain health in unique ways. While social connection helps relieve symptoms of depression, the music that accompanies dancing also stimulates the brain’s reward centers, making us feel good and increasing levels of serotonin.
One study showed that 12 weeks of three times a week dance training meaningfully decreased depression levels in young adults . Another study showed that participation in leisure activities – such as dancing – is associated with a reduced risk of dementia .
