Holding your breath could increase risk of contracting Covid, IIT-Madras study finds

New Delhi: The transport of virus-laden air droplets to deep lung could increase with decreasing breathing frequency, a new IIT study has found.
The study, by researchers at the Indian Institute of Technology Madras, revealed that holding breath or having a low breathing rate can increase chances of viruses, like Covid-19, that are airborne of depositing in the lungs.
Send Holding breath may increase the risk of getting COVID-19 infection, said researchers at the Indian Institute of Technology (IIT) Madras in a study that was published in the international journal Physics of Fluid.
Chennai:
When they modelled breathing frequency in a laboratory to understand how the rate of flow of droplet with virus determines its deposition in the lungs, it was found that low breathing frequency rises the time of residence of the virus and thus increase chances of deposition and consequently the infection. Also, the multiscale lung structure has a significant effect on a personâs susceptibility to COVID-19.Â
