With fresh air, I can heal better

Few simple pleasures in life feel as good as taking a deep breath of fresh air. When you take in more oxygen, the blood vessels in your lungs dilate, which improves the cleansing and repair of the tissues in your lungs and facilitates gas exchange. As a result, you clean out your lungs and help your body get rid of things it does not need - all in one go.

It can provide you with more energy and focus.

When your lungs take in more fresh air, the oxygen levels in your blood increase. Higher oxygen levels mean more of it circulating in your brain, which helps you feel energised and better able to focus and remember information. The Human Cognitive Neuroscience Unit in Northumbria found that subjects who received oxygen compared to standard air performed up to 20% better on a memory test. Oxygen can also boost the production of serotonin, making you feel happier and less anxious. As a result, you'll have a clearer, sharper, and calmer mind, and all it takes is a few breaths of fresh air.

It lowers your blood pressure and heart rate.

The cells in your body require oxygen to function. If there is not enough of it, your heart has to work harder to ensure what is there gets to where it's needed. Fresh air is rich in oxygen, so a few deep breaths help get more of this vital gas into your body. That means your heart can relax, taking less effort to deliver what your body needs. The result? Your heart rate slows, and your blood pressure falls.

It helps you heal faster.

Healing from illness and injury is quite taxing on the body. Since every cell needs oxygen, it is only logical that replacing damaged cells will increase your body's need for air. In addition, oxygen therapy has been shown to shorten recovery time for athletes. Fresh air makes us feel happier and more relaxed and have a measurable effect on our circulatory system, recovery time, and overall health.

Air quality in hospitals

In rooms with high hygiene requirements, the air exchange rate is usually 20-40 times higher than average households. This is to create the healthiest possible indoor environment for patients and minimise the risk of spreading infections. Ventilation systems for hospitals and other recovery environments should be designed to the highest standards of performance.
