The benefits of Ozone

What Is Ozone?

We often hear the word “ozone,” but few people realize how important it is for our health and for life on Earth. Ozone is a gas made up of three oxygen atoms (O₃) that forms the ozone layer in the stratosphere and protects us from the Sun’s harmful ultraviolet radiation. In addition, in mountains and forests, small amounts of ozone purify the air, kill bacteria, and stimulate the respiratory system, making us feel more energetic and refreshed. So even though we cannot see it, ozone is an invisible hero that quietly protects and energizes us every day.

Ozone in Chemistry

In chemistry, ozone is a molecule with the formula O₃, consisting of three oxygen atoms. It is a strong oxidizer and an unstable gas that easily breaks down back into oxygen (O₂). Ozone forms when oxygen molecules (O₂) interact with ultraviolet light or electrical discharges. During this process, one O₂ molecule splits into two separate oxygen atoms, and each free atom binds with another O₂ molecule to form O₃.

Because of its high energy and reactivity, ozone participates in many chemical reactions, including disinfection, air and water purification, and shielding Earth from UV radiation through the ozone layer.

Ozone occurs naturally in Earth’s atmosphere, mainly in the stratosphere, where it forms the so-called ozone layer. This layer protects life by absorbing a large portion of the Sun’s harmful ultraviolet (UV) rays. Ozone has a characteristic fresh, slightly sharp smell and strong oxidizing properties. In low concentrations in nature—such as in mountain air or after a thunderstorm—ozone is beneficial to health: it purifies the air, destroys microbes, and stimulates the respiratory and immune systems. However, in higher concentrations it can irritate and harm the respiratory tract.

Effects on the Human Body

Ozone (O₃) has several positive effects on the human body when present in low concentrations in mountain air. It possesses antibacterial and antiviral properties, reducing the risk of respiratory infections. It stimulates lung function, improves breathing, and supports the oxygenation of tissues through better circulation. Ozone has a mild anti-inflammatory effect on the airways and aids recovery from chronic conditions. Exposure to fresh, lightly ozonated air boosts energy, vitality, and immune defense. The combination of clean mountain air and natural ozone makes Velingrad an ideal place for prevention, rehabilitation, and strengthening of overall health.

The main benefits include:

Antibacterial and antiviral effect – ozone destroys microbes and pathogens in the air, reducing the risk of respiratory infections.
Improved respiratory function – fresh air containing ozone stimulates lung activity and makes breathing easier.
Oxidative stimulation of the body – ozone supports cellular metabolism, improves circulation, and enhances oxygen delivery to tissues.
Reduced inflammation – it has a mild anti-inflammatory effect on the mucous membranes of the airways.
Increased energy and vitality – staying in ozone-rich mountain air stimulates the nervous system and strengthens immunity.

How Is Ozone Formed?

Here is an example of how ozone-related processes occur above Velingrad. The basins around Velingrad, surrounded by dense forests, form a specific microclimate that affects air purity. Trees and vegetation release oxygen and phytoncides—natural antiseptic substances that purify the air. Warm air masses are retained in the basin, while cold mountain air mixes with them, creating fresh, clean air rich in negative ions. This enhances the protective effect of the ozone layer by reducing the harmful impact of ultraviolet rays and contributing to a healthy microclimate. Staying among the forests and mountain valleys improves the respiratory system, calms the nervous system, and increases vitality.

Why Clean Air Strengthens the Effect of the Ozone Layer in Velingrad

Clean air in Velingrad amplifies the positive impact of the ozone layer in several ways:

Reduced pollution – there are fewer dust particles and chemical pollutants in the air that could destroy ozone or reduce its effectiveness. As a result, the ozone layer absorbs UV rays more efficiently.
High oxygen content – mountain air masses are rich in oxygen and negative ions, which stimulate the respiratory system and improve cellular metabolism.
Synergy with the ozone effect – while the ozone layer filters harmful UV radiation, clean air reduces the risk of allergies and irritation, making outdoor stay healthier.

The result is cleaner air, better protection from sunlight, and improved overall health.

Conclusion

The ozone layer above Velingrad—as well as above the entire planet—does not form locally; it is part of the stratosphere at altitudes between about 15 and 35 kilometers above Earth’s surface. Ozone (O₃) forms through the interaction of oxygen molecules (O₂) with ultraviolet (UV) radiation from the Sun.

The process is as follows:

UV rays break oxygen molecules (O₂) into individual oxygen atoms (O).
Free oxygen atoms bind with other O₂ molecules to form ozone (O₃).
Ozone absorbs harmful UV rays, protecting living organisms.

This is a global process. While the clean air in Velingrad or any mountain region does not create ozone locally, the fresh environment helps preserve ozone and reduces pollution.
