Sleep isn't just about feeling rested — it's a pillar of health. Poor sleep is linked to everything from weakened immunity to increased depression risk to cardiovascular problems. If you're already concerned about the health effects of vaping, adding sleep disruption to the list is worth considering.

That said, context matters. Vaping is widely considered to be substantially less harmful than smoking cigarettes. For someone who has switched from smoking to vaping and improved their overall health, the sleep effect of nicotine is a relatively minor concern compared to the benefits of eliminating combustion.

But if your goal is optimal health — and optimal sleep — reducing or eliminating nicotine is the clear next step.
