39. Humidity-High Heat Levels
While it may seem crazy to assume that a real zombie apocalypse could happen out of something like this, follow us here. It comes down to a few factors. Humidity can make it hard to keep fluids in your system and you could sweat a lot of much-needed water from your body. High Heat Levels make for some intense conditions that, without proper food and water, could be problematic.
Overall, heat has the ability to damage your brain and make you believe things are happening that are not really going down. In the desert, you can see things like mirages that resemble an oasis that is nothing but more sand. Due to what heat can do to people, it makes sense to believe they could come off to others like the undead. Look at the appearance of a person who has been in the sun for a long period or that’s nearly dehydrated. Some may also try to kill or eat a human with their brains being so bad from the heat overall.
