Great to have some evidence to back up the ‘feel good’ feelings we already experience 📚
We all know how relaxing a good swim can be. But how does the brain react while swimming?
Swimming is a mediative exercise. Your brain function improves via a process known as hippocampal neurogenesis, where your brain replaces lost cells resulting from stress. When you hit the water, your mood is lifted immediately from the coolness of the water, leaving you free from tiredness and depression.
A study by Dr. Howard Carter of University of Western Australia, School of Sport Science shows how the brain reacts during swimming. The team of scientists, led by Carter, hypothesised that water immersion to the level of the right atrium in the heart would increase the delivery of blood within the brain. The right atrium is located on the upper right-hand side of the heart and is one of four hollow chambers of the heart. The right atrium receives blood from two large veins: the superior vena cava and the inferior vena cava. The job of both veins is to return blood that has provided oxygen to various sites in the body; the returning blood, then, is low in oxygen. The coronary sinus, which is a smaller vein in the wall of the heart, also drains blood into the right atrium. The study concluded that brain blood flow is higher when subjects are immersed in water up to the level of the heart compared to on land, laying the groundwork for further investigation of its effects on cerebrovascular health.
💦 Swimming can improve your mental wellbeing.
It can help you to shut out external stimuli: Once you immerse yourself into the water, outside sounds are cut off. The only thing you feel is the water against your skin. You focus on your breathing, the bottom of the pool, and the ease of the water. Things are simplified when you're swimming. It's a form of moving mediation.
💦 It's a great form of low impact exercise.
Gliding through the water gets your heart pumping. It's also great for your muscles and lungs, as well as having low impact on your joints. When you take care of your body, your emotional well-being is greatly improved. Swimming a few times a week is a great way to exercise and improve your mood.
💦 Swimming releases endorphins.
A good swim workout releases these natural ‘feel good’ compounds. It can also convert excess fight-or-flight stress hormones into muscle relaxation. New brain cell growth is promoted because of releasing stress.
Why is this important for children? Movement is essential for brain development—it directly impacts sensory integration, emotional regulation, and cognitive growth.
