Whether physical or mental, swimming has vast health benefits to offer. You can do butterfly, backstroke, breaststroke, sidestroke and freestyle in the water – all these are great ways to swim your way to a healthier and fitter body. When you swim, your whole body is in action while not murdering your joints, unlike any other type of workout.
Let’s identify five of each of the two important health aspects: physical and mental impacts of swimming.
Physical health benefits of swimming
Basically, swimming is a form of exercise in which you use both your upper and lower body parts, especially your arms, shoulders, back, chest, legs and feet. Swimming is perfect if you want to strengthen your core, and with its nature, you can reap five of the major physical health benefits below.
1. Gain cardiovascular strength
Swimming is a killer cardio exercise! It involves mainly large muscle groups working together at the same time, which also needs your heart to work hard in order to pump enough oxygen throughout your body. Consequently, it enhances your cardiovascular strength.
Cardiovascular exercise, like swimming, works on bettering the heart, lungs and circulatory system. In fact, research suggests that regular swimmers have lowered their all-cause mortality risk by 53 percent, 50 percent and 49 percent, in comparison to those who have sedentary life, walkers or runners, respectively.
The researchers derived the claim after they adjusted certain factors, including age, body mass index (BMI), smoking status, alcohol consumption and family history of cardiovascular disease .
A 2016 study further indicates that swimming can help decrease blood pressure after fifteen overweight adult males involved in this study completed eight weeks of training and four weeks of detraining .
2. Have better quality sleep
Regular swimming can help promote better sleep at night, which makes it a good choice of exercise for older adults. Research reveals that aerobic exercise, like swimming, can boost the quality of life and sleep of adults with insomnia after they engage in the form of exercise for weeks .
One factor that disrupts your healthy sleeping is the lack of exercise; hence, swimming, as a form of physical activity, can help in bettering sleep. Your body temperature increases during swimming, and it drops after, which signals your body that it is time to sleep. Hence, enjoying a few hours at the pool within a few days can enhance the quality of your sleep over time.
3. Maintain lean and bone health
As a full-body workout, you can get a metabolic benefit when you regularly swim. In fact, a person with 155 pounds can burn around 432 calories after swimming, which is higher compared with 266 calories at a moderate pace of walking, as cited by the Harvard Medical School .
In the 2021 study, the researchers found that around 16 weeks of swimming can lead to significant reductions in body fat and body mass index, as published by the BMC Sports Science, Medicine and Rehabilitation .
Many people all around the world have osteoporosis or low bone mass. In fact, one in two women is at risk of breaking a bone because of osteoporosis versus one in four men. Resistance training and high-impact physical activities have always been the top-tier standard for enhancing bone density – swimming may definitely help.
4. Help with chronic pain
Swimming can help with certain conditions, such as arthritis and fibromyalgia, which can cause reduced mobility and, in many cases, short- or long-term pain. A range of aquatic activities is known to aid people with musculoskeletal conditions to enhance physical function and quality of life.
In a study involving people with osteoarthritis, it was found that the participants who swam for 45 minutes three days per week can lead to less joint pain, minimized stiffness and improved muscle strength .
While water workouts may be challenging, the buoyancy of the water adds resistance but is still low-impact at the same time. Hence, aquatic physical therapy can help start and condition your body, especially for people with fibromyalgia or more severe pain.
5. Strengthen lungs
Lungs are significant benefactors of swimming, so if you have been diagnosed with a lung condition, like asthma or chronic obstructive pulmonary disease, you may benefit a great deal.
Swimming trains the body muscles that are involved with respiration. It helps in enhancing lung volume and breathing techniques. Also, the pool can provide an ideal exercise setting if you have asthma because it is humid, warm and usually a low-pollen environment.
However, you should first consult with your doctor before starting a swim routine, especially if you have a lung or other medical condition that could interfere with your ability to exercise.
Mental health benefits of swimming
As a form of exercise, swimming is good for mental health. Exercise can generally release happy chemicals, such as endorphins and serotonin, that improve your overall mood. To be more particular about the mental health benefits of swimming, check out the following.
6. Reduce anxiety
Managing the symptoms of anxiety can be a real challenge; good thing regular swimming may help.
Many research studies have shown that being physically active can positively impact your mental health, particularly in increasing self-esteem, decreasing the risk of depression and slowing cognitive decline. One research suggests that swimming can significantly reduce the symptoms of anxiety for 1.4 million adults in Britain .
In another study, the researchers found that swimming sessions should be between 30 to 60 minutes, depending on your fitness level and needs. Additionally, aquatic exercise was found to be a promising conservative therapy for mental health management , particularly:
- winter swimming
- leisure swimming
- competitive swimming
- aquatic aerobics
7. Help with symptoms of depression
Swimming can release endorphins, which are the so-called “feel-good hormones” that ease the melancholic feelings of depressed people. Physical activity works wonders on your brain and promotes the growth of new brain cells.
A 2020 research study involved participants in a 10-week swim program to reduce fatigue and anger and symptoms of depression. In the end, the researchers concluded that swimming could improve mood and a sense of well-being. An extensive review of multiple studies backed up the claim that swimming significantly reduces symptoms of depression and enhances mood .
8. Relax and reduce stress
After a stressful day, you may want to consider swimming as it is known to help in clearing and relaxing the mind. Research suggests that it also helps with the growth of new brain cells in the areas of the brain which break down because of long-term stress. Although studies have not been conducted on humans just yet, it is believed that swimming may have a similar effect on us.
Swimming may not be the first thing that comes to mind when thinking about relaxation techniques; however, it is as effective as the others with its low-intensity nature .
You can meditate by doing a regular rhythm of swimming strokes paired with the lapping of the water. When the water hits your skin, you can feel or experience something as good as a massage, demonstrating why aqua therapy is commonly used for fitness rehabilitation.
9. Boost brain health
Swimming can boost overall brain health as it supports the production of brain-derived neurotrophic factor (BDNF), which is a compound that aids in repairing brain cells and promotes the growth of new ones. BDNF enhances your brain’s neuroplasticity, resulting in improved cognitive function, including learning and memory.
Research discovered that the brain’s blood flow increased when in water. Having good blood flow to the brain is essential for supplying glucose, nutrients and oxygen – with this, swimming can boost brain health. Moreover, submerging yourself in the water can improve memory, concentration and mood enhancement .
It is further revealed that the brain’s structure has the potential to grow as a result of exercising, making the oxygen supply increase in the brain which then allows the brain to receive more nutrients.
10. Release endorphins
Any form of exercise, including swimming, triggers your brain to release endorphins. When your brain releases the hormone, it interacts with brain receptors to trigger a positive or happy feeling and significantly reduces the feeling of pain and stress. The common term “runner’s high” is a euphoric feeling caused by endorphins that you may experience after completing a workout.
Experiencing the runner’s high after a workout can motivate you to do it regularly. The regular release of endorphins can enhance mental health over time and helps your body respond better to stress. Your body recognizes that physical activity is proven to lead to at least 30 percent of enhancement in self-worth increasing general satisfaction in life.
Swimming can help you live longer
Overall, swimming can actually help you live longer and research has proven that as well. In a 2017 research, experts found that swimmers had a 28 percent lower risk of early death and a 41 percent lower risk of death because of heart disease and stroke in comparison to people who don’t swim . Hence, doing regular exercise, like swimming, can increase your longevity.
