Chef Guy agrees with Leo that the so-called "Zoom fatigue" is setting in. Could it be due to bad audio quality? Leo says that could definitely be a contributing factor. The better quality audio you provide, the better. But most people Zoom using their computer laptop microphones. Would a lav and earbud microphones help? Leo says that a better choice is a Plantronics Model 540 or 478 USB headset. But good luck getting them these days.
