A new study presented at the Physiological Society’s Long COVID: Mechanisms, Risk Factors and Recovery programme demonstrated a small handheld breathing device that helps reduce breathlessness and improved physical fitness of people with long COVID. The UK-based researchers analysed 148 participants in randomised intervention and control groups with this device to find that breathlessness was reduced by 33 percent, twice the level considered clinically meaningful, in the intervention group compared with the control group. They also observed a 10 percent increase in fitness along with a 36 percent increase in the intervention group as compared to the control group which reportedly added up to a  2-14 times greater health improvement for the intervention group compared to the control group. The findings would aid future recovery strategies and a home-based rehabilitation to help people recover from Covid-19.
