Surely you very often go to the shores of the coast in the open ocean. Then have you ever felt more fress and excited when you were on the beach or the high seas? Of course the answer is yes! This is caused by the beach and the sea has long been believed to be a comfortable and refreshing place for people who often visit it. So because of this so many people go to the beach not just to play, but to calm their minds or breathe typical and healthy coastal air.

In one study conducted by experts in Germany proving that this is not just a suggestion. Air and sea water do have properties for the human respiratory system. This means that people with respiratory problems such as asthma can enjoy the atmosphere of the sea while undergoing natural therapy to help relieve asthma symptoms.

Based on the opinions of the experts above, can that happen? In one class VII textbook, explaining at length, I conclude that, to understand how air and seawater help asthmatics, you need to understand what happens when an asthma attack.

"Asthma attacks occur because of a disturbance in your respiratory tract. Muscles -The muscles around your respiratory tract will suddenly become tense and narrow "(Opinions of the doctors)

Then when this happens. Then usually this will be followed by swelling or inflammation in the walls of your respiratory tract. The walls of the respiratory tract begin to produce excess mucus so that oxygen will become more clogged to enter the lungs. With clogging with mucus, the air cannot enter the lung space so this is the cause of shortness of breath.

This therapy was discovered by accident because I myself pay attention to my family who has the disease and when it is on the shore of the beach the breath suffers from slowly recovering. Thus I draw one conclusion that, One of the natural therapies and a good lifestyle for asthmatics is to breathe the sea air that is around you. It should be noted that a good sea and beach for asthmatics are still clean, free from pollution or pollution, and far from industrial estates. Because if there is a beach close to the industry the air will be polluted with air pollution.  ### **On the beach it contains a lot of high oxygen and is very clean** Perhaps you have heard the teacher's explanation when you were still studying in the past, our teacher said "Beaches and seas are located in the lowlands which have more oxygen than places in the highlands such as mountains". In my opinion this happens because Earth's gravity holds oxygen at the surface of the earth. Then the farther away from the plains and sea level, the air pressure and oxygen levels will decrease. Then this is the reason why many people feel dizzy, short of breath, even faint when in a high place. According to experts, many of the diseases caused by altitude are experienced by mountain climbers.

Those who suffer from asthma are at risk of having an attack if they are in places with limited oxygen levels. So, being on the beach with abundant oxygen levels can make asthma sufferers breathe more freely and freely, especially if you often spend time or live in the highlands.

Then besides the benefits mentioned above the sea and the beach still have other secrets that must be known to asthmatics. The air you breathe in the sea or beach contains small drops of sea water so that sometimes sea and beach air can feel salty. Therefore, the air that contains sea water is very healthy for the body because it is rich in salt, iodine and magnesium. These three elements function as aerosols which will stimulate an immune reaction in the respiratory organs in the human body.
