Why is air important?
All living things need air.
Air is all around us. Air is everywhere. And there is neeed of air is essential to live in. Therefore, air is a major component of earth and contains a blend of elements (for example oxygen, carbon dioxide and nitrogen) that helps human life to sustain itself.
Without air, there is no life.
People can stay alive for days without water and for weeks even without food. But without air, one cannot survive for more than a few minutes. This is why air is the most important thing in life. The air we breathe not only helps us stay alive, it also determines the quality of life we live.
Air is essential.
All living things breathe in air, breathing is part of a process called respiration. Air contain carbon dioxide which is use by plants for photosynthesis. Animals need air for breathing to carry out the reactions that release and transform energy from food to grow and live life.

We cannot see air, but we can only feel its presence.
Presence of the air
Air has force. Moving air has force. It can move things for example a sheet of paper can move around the room if there is a physical component to move it such as a fan.
Air fills space. Air has mass and takes up space, for example you can fill the balloon with air.
Air has weight. Air has no weight when it is free to move from one place to another, however it contains weight when it is filled inside any container.
Air moves. When the air moves fast, it is called wind. Wind can move things.
Air is a protection. On Earth we have an atmosphere filled with air, acting as insulation. Ozone, a gas in the air, also protects us from sun radition.
Use of air. Air/wind can run windmills & sailboats, and other movable machinery. Aeroplanes flie due to the presence of air. Oxygen in air aid combustion and burning of fuels to produce heat, electricity, power machinery and so on.
Bits of interesting things
Air is mostly gas — it's a mixture of different gases creating the Earth’s atmosphere (78% of nitrogen, 21% oxygen and other gases, such as carbon dioxide, neon, ozone and hydrogen).
Air isn't just gas — it also holds lots of tiny particles called aerosols (for example dust and pollen). In the air can also be soot, smoke, and other particles from car exhaust and power plants — major contributors to air pollution.
Air contains life — living organisms can also be found hanging out in the air. They are called bioaerosols (living tiny microbial organisms) and can travel long distances via wind, rain, or even a sneeze.
Air also holds water — relative humidity is the amount of water that the air can hold, typically measured in percentages. And the highest level of relative humidity can be 100%.
Air changes as it moves up — air seems light, but there is a lot of it pushing down, this is called air pressure. The air pressure is lower the higher it is.
Essential aspects of fresh air
This is related to the practical aspects of connecting the inside to the outside. For example, like airing out a building or being able to act in connection with the weather and the house itself.
This is from the perspective of the human body and its functions, i.e. regulating of body heat and odour, fresh air from activities in the house but also enjoyment of fresh breeze in a building.
This relates to care and impression, the elements that deal with our need for being in control, that is airing your home to provide health for close ones, the feeling of freedom by opening the windows and letting the fresh air in and the sounds and the scents in the house.
Fresh air energises, improves and heals...
It makes you happier.
Seratonin release is affected by the amount of oxygen you have in your blood. Seratonin promotes a sense of happiness and well-being so the more fresh air you have will help to significantly boost your mood. This is often why you feel better, more relaxed and much more refreshed when you have been outside.
It increases your energy and sharpens your focus.
20% of the oxygen you breathe in is used by your brain to function. Increasing the amount of fresh air you have can provide greater clarity to the brain, promoting optimal function whilst helping you to think, focus and concentrate better.
It strengthens your immune system.
Each cell in the body needs oxygen to perform the metabolic processes necessary to sustain life. By increasing your intake of fresh air, you increase the amount of oxygen supplied to the body. This promotes the elimination of toxins and the destruction of harmful bacteria, parasites, and viruses by the white blood cells in the body.
It is good for your digestive system.
Fresh air increases oxygen flow into your cells which improves circulation and cell function and helps you digest food more efficiently. But if you work in an office where you are busy all day long and probably take your lunch in a hurry to resume work; your blood supply to the digestive tract will be diverted. Instead, of it flowing to digestive tract, you'll have more blood being supplied to the brain to help maintain concentration. This, in turn, may disrupt the proper digestion of food and facilitate indigestion and abdominal discomfort.
It helps you sleep better at night.
Fresh air gives you a burst of oxygen, which increases the feel-good hormone serotonin in the brain. Serotonin helps you stay calm and relaxed, and this can helpo you experience a more peaceful sleep at night.
It lowers blood pressure and heart rate.
Every cell in your body needs oxygen to function. When there isn't enough to go around, your heart needs to work harder to make sure that what's available gets to where it needs to go. Fresh air has plenty of oxygen, so a few deep breaths helps to bring in more of this vital gas to your body. This means your heart can relax, since it takes less effort to deliver what your body needs. End result? Your heart rate slows down, and your blood pressure lowers.
It reduces airborne illnesses and infections.
Breathing in fresh air can help to reduce airborne illness and infection. This is because bacteria and viruses have a reduced chance of survival in fresh air.
It helps you heal faster.
Healing from illness and injuries is pretty taxing on the body. Since every cell requires oxygen, it makes sense that replacing damaged cells increases your body's demand for air. While oxygen therapy has been shown to help improve recovery time for athletes, fresh air can help you feel better and heal faster, too.
It helps clean your lungs.
Fresh air is good for your lungs. When sitting indoors, it's common to breathe shallowly, inhaling the air into the top of your lungs, known as apical breathing. When outdoors, moving, walking or jogging encourages increased diaphragmatic breathing. This means that you breathe more deeply, drawing more air deep into the bottom of your lungs. This not only brings more oxygen into your cells but helps the lungs to expel more airborne toxins from the body. This therefore helps you to cleanse from the inside.
It can prolong your lifespan.
When you are exposed to fresh air, it can help increase your lifespan by improving your overall health. Fresh air contains a variety of important chemicals and elements that can improve your immune system, keep your lungs healthy, and even protect your heart.
