Exhaustion can make you vulnerable to cold sores, so make sure you’re fighting fatigue by getting plenty of rest. Like stress and illness, fatigue can zap your immune system, making you easy prey for a cold sore outbreak. While there are plenty of things that can interfere with getting a good night’s rest — from stress to noise, to drinking caffeine too late in the day — here are some ways to set yourself up for quality sleep.
