Heat affects two main things: the battery and the e-liquid. Lithium-ion batteries dislike high temperatures—they can degrade faster and, in extreme cases, become unsafe. The e-liquid gets thinner when warm, which can cause leaks and make the coil flood. Both add up to a vape that tastes off or stops working mid-afternoon.

For remote workers, the challenge is that your day isn't confined to an office. You might be at a park, a rooftop, or a festival, and your vape is in a bag or pocket. It's easy to forget that it's baking in the sun.
