Use air filters and an air purifier to clean the air in your gym


When you exercise, you breathe in a bigger volume of air – which also means that you inhale a larger number of unhealthy particles in outdoor or indoor air. When you rest, you normally take 12-15 breaths per minute. One breath consists of around half a litre of air. During exercise, your intake of air rises from 6-7 litres per minute to up to 100-120 litres per minute.

Exercising outdoors, walking, running, playing tennis or performing some other outdoor training activity, means you have much less control over the air you breathe. If you live in a pollution hotspot you should avoid exercising near roads where the traffic is heavy.  The requirements for creating a healthy indoor environment will vary, depending on where you live.  Indoor air pollution can exceed acceptable levels for fine particles a hundredfold. When particles and other substances pass into indoor air, they combine in new ways with the substances and particles already present inside buildings. These combinations can be much more aggressive and, therefore, more harmful to us.

High-quality filters in a building’s ventilation system can filter and eliminate a significant proportion of the airborne particles originating from outdoors. And an air purifier can be used to remove pollutants from indoor sources. If these measures are taken, the indoor air quality (IAQ) can be improved considerably, even in places where the outdoor air is heavily polluted. Continue reading

Indoor Air for Athletes – A Brief Guide

A definition of indoor air quality

Indoor air quality (IAQ) is the quality of the air inside a building. It is defined on the basis of the concentrations and levels of incoming chemical and biological substances and the comfort-related factors which affect people and processes. The quality of indoor air is a factor that is often neglected and that has an impact on people’s health, well-being and performance.

Camfil has created ‘A brief Guide to indoor Air for Elite Athletes’ to provide a better understanding of how air affects the body and, therefore, performance.

Your lungs and clean air

The function of the lungs depends on clean air even in the outermost of the seven million air sacs (alveoli) where the gas exchange with the capillaries takes place.

The blood flows through the capillaries and gives off the carbon dioxide (CO2) that has formed during the metabolic process. At the same time, it takes in oxygen via the alveoli. The oxygen is transported from the alveoli to the muscles and other organs. The carbon dioxide and other impurities leave our bodies when we breathe out.

Nanoparticles, which are no larger than a virus, can become deposited (trapped) in the cell membranes (walls) of the alveoli. These have a total surface area of around 70 m2 and are highly sensitive to particles and harmful substances. If these substances remain in the respiratory system, they can contribute to the development of emphysema, oedema and other serious illnesses. Continue reading
