What is the difference between positive and negative ions and how do they impact our overall well-being?

Positive ions have more protons than electrons, while negative ions have more electrons than protons. Positive ions are often associated with pollution and electronic devices, while negative ions are found in nature, like near waterfalls or after a thunderstorm. Negative ions are believed to have a positive impact on our well-being, as they can improve mood, increase energy levels, and reduce stress, while positive ions may have the opposite effect.
