Until the 1960s, neuroscientists thought that damaged brains cells could not be replaced. But that theory was disproved when researchers started to notice the creation of neurons (neurogenesis) in the adult brains of humans and animals. Studies show that aerobic exercise plays a key role in helping to repair damage to neurons. Exercise increases the levels of a protein named brain-derived neurotrophic factor that boosts cognitive function, including learning and memory.

New brain cells and connections

<ul><li>In a study with rats, swimming was found to stimulate brain pathways that reduced inflammation in the hippocampus and slowed down cell death. Swimming also helped neuron survival and lowered the cognitive impact of ageing.</li><li>Another study paid attention to the impact of swimming on mental agility in elderly people. Researchers found increased mental speed and attention compared with non-swimmers.</li><li>In children, swimming (aerobic exercise) showed a clear cognitive benefit over anaerobic exercise such as CrossFit.</li></ul>

Swimming and brain health

Research shows that swimming regularly can have several health benefits:
<ul>
<li>Improve your memory, cognitive function, and mood</li>
<li>Strengthen your immune system</li>
<li>Mend damage from stress</li>
<li>Create new neural connections in the brain</li>
</ul>

Swimming provides unique benefits

Of all the aerobic exercises, swimming may be the best for your brain, especially when it comes to memory, stress, aging, and other neurological functions.
