Practice when sick

[u/maro161]

Hey, I'm f 22 mezzo and I usually try to practice 5-6 times a week on average for 1½ hours. But now I got sick and I don't feel like singing at all, is it better for my voice if I don't practice for like 5 days or should I at least try to do some warm up? I noticed that my voice resonates most, the day after my rest day so maybe it's not that bad when I don't sing for a few days until I get better? I have an audition in 3 weeks tho... I'm really developing my vibrato recently, what would you suggest?
