What are the major dangers of pesticides to humans?

Pesticides can be harmful to humans if exposure is high or frequent. Short-term effects include headaches, dizziness, skin irritation, and breathing problems. Long-term exposure may increase the risk of cancer, hormonal imbalance, nerve damage, and weakened immunity. Children and pregnant women are more vulnerable. Pesticides can also contaminate food and water, slowly affecting overall health when consumed over time.
