The Health Benefits of Fresh Air You Should Know About

“When you can’t breathe, nothing else matters,” the American Lung Association tells us.

And while that’s true, the kind of air you’re breathing will determine the health benefits you experience.

Breathing fresh air—clean air that is free from both indoor and outdoor pollution—is an essential part of caring for our bodies, which God has given us. It gives our bodies the oxygen they need to stay physically healthy. It invigorates our minds. And in turn, the physical and mental benefits help us to be spiritually healthy and better connected to God.

On the other hand, when we’re breathing polluted or smoggy air, we’re at a greater risk of headaches, tiredness, a sluggish mind, coughing, bronchitis, sinusitis, and even cancer.¹

Here, we’ll dive into the reasons why fresh air is so essential for overall health, and we’ll look at some ways to make sure we’re getting all the fresh air we need. We’ll cover:

• Physical benefits of fresh air
• Mental benefits of fresh air
• Spiritual benefits of fresh air
• How much fresh air do we need?
• How can we get fresher air?

Physical benefits of fresh air

Oxygen is absolutely necessary for our bodies to make energy and keep us alive. Clean air is the best source of this oxygen while providing many other benefits for physical health.

Deep breaths of fresh air increase the concentration of oxygen our lungs take in. It may be one of the reasons fresh air has been shown to improve body temperature, heart rate, and breathing efficiency.²

Fresh air also contains negative ions that energize the air—and us—by increasing the amount of oxygen we take in.

What exactly are these negative ions?

We’re so used to hearing the word “negative” and thinking “bad.” But here we’re talking about molecular polarity. Negative ions result when the air molecules “have gained or lost an electrical charge.” This usually happens when moving air, moving water, or sunlight breaks the molecules apart.³ These negative ions bind together with unhealthy particles, helping to remove them from the air. Think of them like nature’s air purifiers.⁴

Not surprisingly then, fresh air may have as much as ten times more of these negative ions than stale air!⁵

And researchers believe that fresh air is also one of the reasons that the Japanese practice of “forest bathing”—spending time in forests—impacts physical health in so many positive ways.⁶

Forests have a higher concentration of oxygen due to the way trees convert carbon dioxide into oxygen. And that higher concentration of oxygen can mean the following for us:

• Increased energy levels⁷
• A stronger immune system⁸
• Lowered stress levels⁹
• Better function of antioxidants (substances that help protect the cells from damage)¹⁰
• Less inflammatory markers related to coronary artery disease and chronic heart failure¹¹

Mental benefits of fresh air

Because of the connection between the mind and the body, the physical benefits of fresh air translate to mental health, too. Though the brain only makes up 2% of the body, it uses 20% of the body’s oxygen supply. Fresh air is vital for the brain.

Have you ever found yourself stuck in a rut when learning something or trying to solve a problem?

In exasperation, you shut your laptop screen and went for a short walk. And when you returned, your mind felt clear and refreshed.

You were experiencing the mental health benefits of fresh air.

The increased oxygen and negative ions combine to help:

• Relax the mind¹²
• Improve focus and learning ability¹³
• Improve mood (by increasing levels of serotonin, the brain’s happiness hormone)¹⁴
• Decrease stress, anxiety, depression, and anger¹⁵

Spiritual benefits of fresh air

Adventists believe that we are holistic beings whose physical, mental, and spiritual health are interconnected. Experiencing the benefits of fresh air means that we will have clear minds for connecting with God.

The Bible calls our bodies temples of the Holy Spirit (1 Corinthians 3:16–17) because the body houses the mind, through which we talk with God and perceive the wisdom He’s seeking to give us. This means that what we choose to think about can have eternal consequences:

“For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace” (Romans 8:6, ESV).

And fresh air? When we experience its benefit on the mind, we also experience its spiritual benefits:

• We’re able to understand God’s Word better
• We have a clearer mind for prayer
• We can focus on God and His Spirit
• We make better decisions

How much fresh air do we need?

When it comes to the amount of fresh air you need, the more, the better! Recent research suggests at least 30–40 minutes per day.

But unfortunately, most Americans spend over 90% of their time indoors, where fresh air tends to be lacking and the air may be polluted by cigarette smoke, paint, chemicals in furniture, household chemicals, and more.

In 2019, researchers surveyed a group of people about the time they spent in nature and their resulting sense of health and wellness.

They found that those who spent between 200 and 300 minutes per week (30 and 40 minutes per day) outdoors had the greatest sense of health and wellbeing.¹⁶ Though there were other factors involved (such as spending time in green spaces), fresh air no doubt played a part.

The good news is that fresh air may continue to make a difference in your health even when you can’t be in it all the time! According to one study, the physical benefits of going on a forest bathing vacation lasted for at least seven days afterward.¹⁷

How can we enjoy more fresh air?

Follow these simple tips:

• Spend time outdoors in an environment full of negative ions
• Open your windows
• Get some house plants
• Use air purifiers and filters

Participate in outdoor activities

Indoor air can have up to 100 times more pollutants than outdoor air! Doesn’t that make you want to get some clean outdoor air?

Look for places out in nature where the concentration of negative ions is likely to be higher. Places such as waterfalls, creeks, rivers, forests, and the ocean.

Some ideas for spending time outdoors are:

• Walks in the sunshine
• Outdoor exercise
• Working in your yard or garden
• A picnic at a park
• Reading a book outside

But there are ways to improve indoor air quality, too.

Open your windows

Let some of that fresh outdoor air into your home! If the weather is warm and you don’t live in a polluted city, open those windows wide. For better ventilation, run a fan and open the windows on opposite sides of your house to allow a crosswind.

On cold days, even cracking the window for a few minutes can help rejuvenate the indoor air.

Get some house plants

Plants take in carbon dioxide and release oxygen into the air, making them great for improving air quality. They also absorb toxic pollutants that come from carpets, furniture, cleaning products, and paint.¹⁸ In fact, one plant alone can remove up to 90% of pollutants in a room.¹⁹

Use air purifiers and filters

Air purifiers can help improve indoor air quality by removing unhealthful particles. Also, place air filters in your vents and keep them clean to ensure that the air circulating through your home is clean.

Breathe deep of fresh air and God’s Spirit

God cares about every aspect of our health—including the air we breathe. He designed fresh air to invigorate us physically, mentally, and spiritually. This is why Adventists are intentional about getting out in nature to enjoy the benefits of fresh air.

The Bible uses air as a metaphor for the Holy Spirit. Just like we need fresh air moment by moment, we need the Holy Spirit to help us navigate our daily lives.

So let’s make sure we’re getting deep breaths of both kinds of air—the fresh outdoor air and the air of God’s Spirit. Both are good for you, refreshing your mind, body, and spirit.
