Blow your nose. Don’t you dare sniffle! Be sure to regularly blow your nose to prevent mucus from clogging up your sinuses. Be sure not to blow it too hard though, or you could cause yourself to have an earache. The best way to do it, is to press a finger over one nostril while you blow gently to clear the other. Wash your hands after blowing your nose. This brings us to one more important decision, tissue or handkerchief? In an everyday situation, where you have a trash receptacle available at all times – the tissue seems to be a more hygienic option since you’re immediately disposing of the wad that’s more than likely to be teeming with bacteria. However, if you use the tissue method when you’re spending your days in a truck you’ll still be sitting next to your recently expelled mucus for hundreds of miles. This leads us to believe that in the case of a driver – neither the handkerchief nor the tissue win the race when it comes down to hygiene. The deciding factor should be whichever does the least damage to your own nose after repetitive use – so long as you’re washing your hands and wiping down your own steering wheel periodically.
