How does oxygen influence on human body

How oxygen affect us?

As we know our atmosphere is consist of about 78 % nitrogen, 21 % oxygen, 0.9 % argon, and 0.1 % other gases like carbon dioxide which we are familiar with.

 

Oxygen is quite vital to our human being

 

Why we cannot live without oxygen? Our body need oxygen to produce energy like a vehicle need gasoline. Oxygen is an important energy source for living. Unlike plants inhale carbon dioxide, we inhale oxygen and exhale carbon dioxide. The oxygen we inhale passes through our lung to our blood by red blood cells, which carries oxygen and transports oxygen to our various tissues and organs, including the brain, heart, kidneys, and our immune system. If hypoxia occurs, the function of these organs will be impaired, which will affect our metabolism and result in body hurts or even death. So oxygen is very important to our life.

Humans need oxygen to live, but not as much as you might think. Our lungs supply oxygen from the outside air to the cells via the blood and cardiovascular system to enable us to obtain energy. As we breathe in, oxygen enters the blood through our lungs. At the same time, the carbon dioxide in the cells of the body diffuses into the blood and break away from lungs as we breathe out. For humans and many animals, we have a special range of oxygen %age requirement. As the OSHA(The Occupational Safety and Health Administration) determinated, the optimal range of oxygen in the atmosphere for human beings is between 19.5 and 23.5%. So what if the oxygen level runs over 23.5% or under 19.5%?How the oxygen level mattes?

Under the optimal range(19.5%)

Serious side-effects can occur if the oxygen levels drop outside the optimal range. When oxygen concentrations drop below 19%, your cells fail to receive the enough oxygen needed to support your physical activity. It can cause your blood oxygen levels to be too low. Low blood oxygen may make you feel short of breath, tired, or confused. It can also damage your body. Mental functions will get serious damage and dyspnea when the oxygen concentrations drop to 14% or lower; at these levels, our body will be very hard to support any activates because it is a kind of self-protect function in our body system; the red blood cells will carry more oxygen to our brain which is the most important organ in order to ensure brain can work normally to provide stable operation of system. And when the oxygen level drop below 6%, no human can survive.

Over the optimal range(23.5%)

Higher-than-normal oxygen levels aren't as harmful to life as lower-than-normal oxygen levels, but there is an increased change of fire or explosion risk. Also with extremely high concentrations of oxygen in the air, our body can occur harmful side effects. Very high levels of oxygen cause oxidizing free radicals to form. These free radicals will attack the tissues and cells of the body then cause muscle twitching. The effects from short exposure can most likely be reversed, but lengthy exposure can cause death.

Altitude Sickness

The right amount of oxygen starts at sea level. When altitude is increased, such as driving or climbing up a mountain, there is less atmospheric pressure. Lower pressure cause air to expand more than it does at sea level. While the ratio of air remains the same like nitrogen and oxygen, less molecules are available within the same volume. You Inhale less oxygen molecules when you breath at high altitude than at lower altitude. That will cause altitude sickness in essence side-effects of noun enough oxygen. People may experience nausea, headache and fatigue. Without proper treatment, the problem can become more serious.

Chronic hypoxia and aging is mutually causal

 

Chronic hypoxia can promote the aging of various organs, accelerate the process of aging, leading to a variety of chronic diseases;

The aging of the human system will also directly reduce the reduction of oxygen intake in the elderly, reduce the ability to transport oxygen, and reduce the efficiency of using oxygen, so that the whole body tissue is in a state of chronic hypoxia with different degrees.

 

  1. Hypoxia in the brain

Human tissue hypoxia will appear functional damage, such as brain hypoxia is light, dizziness, tinnitus, heavy, brain cell necrosis, loss of consciousness and so on.

 

  1. Heart hypoxia

Most cardiac diseases can cause myocardial ischemia and hypoxia. Heart palpitations, discomfort in the anterior heart area, sometimes the anterior heart area pain or radiation pain, in severe cases can lead to shock.

 

  1. Muscle hypoxia

Muscle hypoxia usually occurs after strenuous exercise. Exercise exceeds the intensity of aerobic exercise, and oxygen can not keep up with the supply, forming an anaerobic metabolism, resulting in a large accumulation of excessive product lactic acid in the body. Muscle appear stiff, sour pain, serious but also will be muscle spasm.

 

The human body is a complex and sophisticated chemical factory that allows the oxygen taken into the body to be metabolized. At this time, the waste is excreted. If this waste stops in the body, it means oxygen is insufficient. Therefore, in order to maintain health, attention must be paid to the balance of oxygen demand and supply. Add an oxygen bar to the body!

Asthma

What Is Asthma?

Asthma is a long-term disease of the lungs. It causes your airways to get inflamed and narrow, and it makes it hard to breathe. Severe asthma can cause trouble talking or being active. You might hear your doctor call it a chronic respiratory disease. Some people refer to asthma as "bronchial asthma."

Asthma is a serious disease that affects about 25 million Americans and causes nearly 1.6 million emergency room visits every year. With treatment, you can live well. Without it, you might have to go to the ER often or stay at the hospital, which can affect your daily life.

What Does Asthma Feel Like?

Asthma is marked by inflammation of the bronchial tubes, with extra sticky secretions inside the tubes. People with asthma have symptoms when the airways tighten, inflame, or fill with mucus.

There are three major signs of asthma:

  • Airway blockage. When you breathe as usual, the bands of muscle around your airways are relaxed, and air moves freely. But when you have asthma, the muscles tighten. It’s harder for air to pass through.
  • Inflammation. Asthma causes red, swollen bronchial tubes in your lungs. This inflammation can damage your lungs. Treating this is key to managing asthma in the long run.
  • Airway irritability. People with asthma have sensitive airways that tend to overreact and narrow when they come into contact with even slight triggers.

These problems may cause symptoms such as:

  • Coughing, especially at night or in the morning
  • Wheezing, a whistling sound when you breathe
  • Shortness of breath
  • Tightness, pain, or pressure in your chest
  • Trouble sleeping because of breathing problems

Not every person with asthma has the same symptoms in the same way. You may not have all of these symptoms, or you may have different symptoms at different times. Your symptoms may also vary from one asthma attack to the next, being mild during one and severe during another.

Some people with asthma may go for long periods without having any symptoms. Others might have problems every day. In addition, some people may have asthma only during exercise or with viral infections like colds.

Health Aging Month

Healthy aging was proposed by the World Health Organization at the Copenhagen Conference in September 1990.
