Sometimes we don’t think about something as simple as the fresh air we breathe every day. It’s believed that we only need to eat healthily or do exercise to take care of ourselves, but air is also a crucial part of our health. In case you were one of those people who didn’t know the importance of clean, fresh air and living far from pollution, we are here to explain to you why it is. So, let’s get started!

Importance of the air we breathe

We should all remember that the quality of the air is a key factor for our health. Breathing polluting air can affect many aspects of our bodies, while being surrounded by clean, fresh air helps us feel better. Even though we don’t normally notice it, the air influences many things, such as our lungs, heart, skin, energy, and even our mood.

Improving breathing

The first benefit we are going to mention is already really important for us; it’s the improvement of respiratory health. When we are not surrounded by polluted air, our airways do not get irritated, and our lungs can work without extra effort. This is great for lowering the chances of suffering from problems like asthma or chronic bronchitis. When the air doesn’t contain harmful particles, the lungs don’t get irritated, and breathing becomes much easier and more comfortable.

Effects on the heart

Of course, the heart also benefits from fresh air.  When we avoid tiny, harmful particles like PM2.5, the blood can move more easily through the body. This helps keep blood pressure healthier and prevents the heart from doing any unnecessary effort.

Body’s defenses

We have already mentioned very important benefits, but there’s more! It’s also important to point out that the immune system becomes stronger when the body receives good oxygenation. When the cells in charge of protecting us from infections get clean oxygen, they can work more effectively. This gives the body more energy and a better ability to face illnesses and everyday fatigue.

And the skin?

The skin, which is the part of our body most exposed to the air, can clearly feel the difference between polluted air and clean air. When we are away from smog and tiny particles, our pores stay cleaner, the skin looks brighter, and signs of aging appear more slowly. Without constant exposure to harmful substances, the skin can stay healthier for longer.

Physical performance and digestion

More benefits! Better oxygenation also helps the muscles. People who breathe clean, fresh air can perform better during physical activity and recover more quickly afterward. Even digestion can benefit, because a well-oxygenated body keeps a more balanced metabolism and a steadier appetite.

Mental benefits

Did you think that was everything? Not at all! There are positive effects for our mind. When the brain receives good oxygen, it becomes easier to think clearly, concentrate, and remember things. In natural environments, the air contains negative ions, which can reduce stress and improve mood. This leads to better emotional balance and a greater sense of relaxation.

What about sleep?

Last, but not least, we are going to talk about another important point: how much clean, fresh air can improve our sleep. Pollution or dry city air can make it harder for the body to relax, but clean air helps us drift into a deeper, more peaceful sleep. Because of this, the body can recharge properly during the night, and we wake up feeling much more rested and energized.

To sum up

We invite everybody to value the spaces where clean, fresh air surrounds us, because breathing it is one of the easiest—and most powerful—ways to care for ourselves every single day. Now that you know more about how fresh air benefits us, I’m sure you are going to try avoiding polluted air.
