How does too much sun make you throw up?

Excessive sun exposure can lead to heat exhaustion or heatstroke, conditions that may cause nausea and vomiting. This occurs as the body overheats, disrupting its normal physiological functions and leading to symptoms like dizziness, weakness, and gastrointestinal distress. Dehydration from excessive sweating can also contribute to nausea, further exacerbating the feeling of wanting to vomit. It's essential to stay hydrated and seek shade or cool environments to prevent these reactions.
