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 person’s susceptibility to COVID-19.
