Swimming has often been touted as among the best exercises for overall health, and its benefits are especially important for seniors. Swimming enhances strength, endurance and flexibility, and does so in a low-impact way that decreases the risk of exercise-induced injury.
Benefits of Swimming for Seniors
Increases Lung Capacity
Many seniors experience changes that may cause a loss in lung capacity. Muscles like the diaphragm can get weaker, lung tissue can lose elasticity which makes airways smaller, and rib cage bones can change and get smaller which leaves less room for your lungs to expand.
Regular cardiovascular exercise like swimming can increase or maintain lung capacity. In addition, swimming movements strengthen your core muscles – the muscles that move the air in and out of your lungs – as a whole. Studies have shown that swimming and practicing breath control can strengthen respiratory muscles.
Aids Heart and Circulatory Function
Swimming, in particular, offers numerous health benefits for the heart.
It helps your circulatory system to better supply oxygen to all of your body and remove harmful waste. This reduces the risk of embolism, a blockage in a blood vessel that can become deadly.
Improved circulation can reduce your risk of stroke and other circulatory problems. It also can help your body move nutrients to cells that need repair.
The pressure from the water surrounding your skin helps move blood around to where it’s needed, particularly if you have edema or swelling in your lower limbs, or poor circulation in your feet and toes because of diabetes.
Swimming can also help you maintain control over your cholesterol levels.
Improves Strength
As you age, you lose muscle mass. But muscle mass can be retained or even increased by exercise. Swimming works many of the major muscle groups all at once. And different swimming strokes can target specific muscles.
Due to the buoyancy of the water, the strengthening exercises of swimming can be performed with less or no joint pain, unlike the weight-bearing exercises typically experienced in your home or a gym.
Increases Flexibility
Swimming can help free up stiff joints and may help you gain a few more degrees or even full range of motion over time.
Swimming and pool-based therapy have long been mainstays of physical rehabilitation after injury, surgery, or severe illness.
Increased flexibility makes it easier to reach high up on a shelf or pick up something off the floor. And improved mobility means more independence for you.
Improves Stability and Reduces Fall Risk
The improved muscle performance associated with swimming translates into a decrease in the number of falls for seniors.
A study that monitored how often 1,700 men over the age of 70 fell over a period of four years found that the men who swam regularly were 33% less likely to fall compared to men who exercised in other ways.
Mental Health Benefits
Studies have shown swimming diminishes stress levels, lowers anxiety, reduces depression, and promotes positive feelings people have about themselves.
Exercise boosts production of chemicals in the brain and body that can significantly alter how you feel. Endorphins, in particular, are a group of chemicals in the brain and nervous system that stimulate cells’ opiate receptors, which regulate pain.
Feel-good brain chemicals are boosted by vigorous physical activity and also increase steroid reserves, enabling you to become more resilient to stress.
In addition, swimming seems especially adept at influencing mood by increasing the number of certain neurotransmitters in your brain, namely serotonin, noradrenalin and dopamine.
In a class or group setting, swimming promotes socialization, which also increases mental health benefits.
Improves Sleep Quality
As many as 50% of older adults have difficulty sleeping, which leads to an increased risk of mortality. Aerobic exercise like swimming leaves the body more tired and relaxed enough to sleep longer and more deeply.
Boosts the Immune System
Your immune system is there to help prevent bacterial, fungal and other potentially problematic agents from running rampant and making you very sick.
Exercise—especially aerobic exercise like swimming—can help support a healthy immune system.
Provides Cognitive Benefits
Aerobic exercise has also been shown to increase the levels of brain-derived neurotrophic factor (BDNF), a protein in your brain and spinal cord that promotes the survival, growth and maintenance of neurons. Studies have shown that increased levels of BDNF can have wide-ranging, positive effects on cognition, memory and mood regulation, all functions of a healthy brain that’s aging well!
