Covid is Airborne: You’re breathing it in
A powerful short video explaining how COVID spreads through the air like smoke, highlighting why ventilation, clean air and respiratory protection matter.
A study of 467 non- hospitalised adults with severe Long Covid found that 31% met diagnostic criteria for Postural Tachycardia Syndrome (PoTS), most of whom were younger women (91%). Those with PoTS had lower physical activity levels, higher heart rates, and reduced walking distances compared with non-PoTS patients, though their overall symptom profiles were similar.
The findings show that PoTS is common and clinically significant in Long Covid, underscoring the need for systematic assessment and tailored management.
A graphical representation of the results is provided below.

N95 and KN95 respirators may look similar, but they are certified to different national standards. Both are designed to provide a high level of filtration, with each rated to filter at least 95% of specified test particles. (Smart Air)
