Whether I have been waylaid by hay-fever, the common cold, or my one bout of COVID, I almost always take a break from the pipe because my head is stuffed full. Whether it is a loss of taste and smell, or being short of breath really didn't matter. For the record, I also lose my interest in Scotch under the same circumstances.
Rest is the best medicine for all occasions - stress is poison; do whatever lets you decompress and get well soon.
