If you live by the sea, travel to the beach a lot, or plan a vacation to the island this summer, you may get more fun out of it than just enjoy it.
People always think that playing at sea is good for health.
Historically, doctors have advised their patients to go to the seaside to improve various diseases.
They will actually prescribe, detailing the exact time, frequency and conditions of the patient in the water.
There is even a name for using seawater for medical purposes: Marine therapy.
In 1769, Richard Russell, a famous British doctor, published a paper advocating the use of seawater in "thyroid disease, he included in his paper damage, jaundice, leprosy and the name of the gland heat at that time.
He advocates both drinking and swimming in the sea.
Today, healing and spa resorts by the sea abound.
They are considered places where people can not only put their troubles down, but in some cases, even cure arthritis.
But did the evidence really pile up?
Does seawater treat skin diseases and improve mental health symptoms?
The seawater is different from the river because it contains a large amount of minerals, including sodium, chlorine, sulfur, magnesium and calcium.
This is why it is very useful for skin diseases such as psoriasis.
Psoriasis is a chronic autoimmune disease.
Where the immune system attacks healthy cells)skin condition.
People with prosiasis often develop weak rashes caused by itchy, scalded patches.
Bathe in natural minerals
Abundant water, including water in mineral springs, known as balnetherapy, has long been used to treat psoriasis.
There is also evidence of climate therapy (
Transfer the patient to a specific location for treatment)
In the Dead Sea is an effective way to treat this disease.
Patients with psoriasis themselves report that they feel better after swimming in the ocean, but this may also be related to sun exposure, which is found to improve symptoms of psoriasis.
Swimming in the ocean is also good for eczema.
Swimming in the sea is a great exercise option for people with severe eczema, as they often exercise in high-temperature and chlorine swimming pools.
But the response to saline is different in eczema patients: Some people think that saline can relieve eczema and some people are uncomfortable.
There is some evidence to support the idea that magnesium absorption is beneficial to the skin of eczema patients-presumably because magnesium absorption reduces skin dryness-and people who use Epsom salt bath will prove this.
It's probably because of magnesium.
Rich seawater can improve the moisturizing of the skin and make it stronger and harder.
Because it is rich in other minerals such as sodium and iodine, the sea water can be considered as a preservative, which means it may be injured
On the other hand, swimming in the ocean with open wounds can expose you to potential bacterial infections.
Rinse or rinse the nasal cavity with salty solution, used as a supplementary therapy by many people with pollen fever and sinus inflammation and infection.
Swimming in the ocean and exposure to salt may be associated with hay fever and rhinitis and other relief of respiratory symptoms.
This is because the saline effect of the sinus liner may reduce inflammation, although the scientific evidence for this is not very reliable.
The director of clinical services at the British Allergy medicine charity claims that people who live in the ocean and swim in it tend to have a healthier respiratory system.
She said that because the sea water is being cleaned and imitating the body's own liquid in the airway lining, they will not be stimulated.
Exercising in a natural environment is more beneficial to mental health than exercising elsewhere.
This is because it combines the benefits of exercise with the restoration of nature.
So is swimming in the ocean.
It can relax, meditate and reduce stress.
Marine biologist Wallace in his 2014 book The Blue Mind
Nichols collects evidence of why people find themselves in a state of meditation and relaxation while in the water, on water or under water.
One reason is the breathing patterns used when swimming and diving.
These stimulate the accessory nervous system (
Systems that control organ function and silence the brain)
It has an effect on brain waves and hormones that have a positive effect on the brain.
The weightlessness of water also has a calming effect on the brain, and can even change or slow down brain waves.
It can help you get distracted from your life and give a sense of mindfulness, a state of being aware of your surroundings in a meditative way. Hydrotherapy (water therapy)
Swimming can also reduce the symptoms of depression and anxiety.
A study has shown that the effect of balneotherapy and the commonly used resistance
An inhibitor called paroxine.
The spa has been widely used in rehabilitation, but here I will focus on the health benefits of swimming in cool waters. Cold-
Swimming can activate the temperature receptors under the skin, which release hormones such as endorph, adrenaline and cortical hormones.
These have therapeutic effects on skeletal diseases (such as fibromyalgia) and skin discomfort, which is a disease of chronic pain and tenderness in the whole body.
Repeated cold water exposure can also lead to an enhanced function of the accessory nervous system, which contributes to organ function.
This is associated with increased release of dopamine and five serotonin.
Depending on the temperature, swimming in colder waters consumes more heat to maintain body temperature-although the overall impact on fat quality is controversial.
Frequent exposure to cold water is also shown to increase the body's immunity.
In general, it is wise to make swimming in the ocean a healthy habit.
