BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to a health mask, particularly an air permeable mask providing oxygen and removing water vapor.

2. Description of the Prior Art

Oxygen, the natural resource available in environment, is basic instinct of human being to live. However, ambient air quality as well as demand and supply of oxygen in a human body have been changed with variable living conditions and life styles which imperil health of modern people, for example, “chronic hypoxia syndrome” with symptoms including inertia, weakness, memory loss, upset, difficulty in sleeping, reactivity weakened and attention deficit

Sunlight, air and water are three essential elements for lives. In this regard, air implies oxygen which is critical to functions of a human body and inhaled through breathing. Oxygen diffused into capillaries through alveolar membranes of pulmonary alveoli attaches to hemoglobin of red blood cells. Oxygenated blood is then pumped through the heart and continuously circulated through the whole body and organs are thereby nourished by fresh oxygen. The human body is energized by oxygen. When blood is fully oxygenated, organs in the human body will function well. In contrast, when blood is short of oxygen, organs in the human body are prone to dysfunction and disease.

In a modern society, more and more people beset by severe environmental pollution, work stress and hectic lives suffer from conditions commonly associated with chronic hypoxia. For example, fatigue, waist pain, backache, yawn, drowsiness, dizziness, distraction, headache, eyestrain, etc. common in office workers working long hours may derive from chronic hypoxia. Symptoms of chronic hypoxia may include, for example, hand numbness, skin pallor, vertigo, blurred vision, poor creativity, blurred thinking, and similar signs of compromised performance. Moreover, some people exhibit chronic fatigue symptoms which may be attributed to hypoxia-related dysfunction.

Such and other disease and dysfunction results from the biochemistry underlying the metabolism of glucose. With oxygen, glucose can be converted into energy, i.e., metabolized under aerobic respiration. Without oxygen, glucose is converted, or metabolized, to produce, lactic acid under anaerobic respiration. Without adequate oxygen to metabolize sufficient glucose to support relevant physiologic performance of the body, excess lactic acid build up after exercise cause muscle soreness.

In addition to oxygen deficit, humid environment may also be detrimental to health. For example, east coast is characteristic of high relative humidity all year around which discomforts residents in summer time particularly. In contrast to 60%, the relative humidity best for human being, the humidity, 100%, in east coast during the rainy season, making walls and clothing moldy, and jeopardizing health. In environments with high temperature and humidity environments, rampant bacteria, viruses and allergens are associated with ailments, such as allergy, asthma, athlete's foot and dermatitis. In addition, humidity may cause excessive leeching of harmful chemicals from building materials which may then contaminate the surrounding environment. Thus, inhabitants of perpetually high humidity environments may suffer from disorders.

The morbidity of asthma will be increased by 3% with indoor humidity rising 10% according to research in Germany; furthermore, dust mite and mold prefer environment in which the relative humidity is more than 70%.

A direct correlation of humidity with allergic conditions is supported by research of the University of Otago, New Zealand studying 46,000 children in 20 countries, whom lived in damp moldy apartments were determined to harbor a higher incidence of allergy-related ailments such as asthma, hay fever and eczema.

Humid environment has further been found to have a debilitating impact on blood pressure. In addition, high humidity may also increase the risk of stroke of a patient suffering from cardiovascular disease in humid weather.

More and more people wear masks to guard against air pollutants or an infectious agent. Wearing mask can filter the dust and bacteria from inhaled air but sometimes induce discomfort by mask contact.

Unfortunately, however, when a mask is worn for an extended time, it causes discomfort. Moreover, poor air quality resulting from accumulated exhaled carbon dioxide and water vapor is exhaled inside of the mask reduces the amount of oxygen inhaled by the mask user as compared to breathing the surrounding open space.

Therefore, a need persists to provide mask which can not only remove dust and bacteria but also provide oxygen and remove water vapor to promote air quality inside the mask.
