Myth 1: Vaccines cause the diseases they aim to prevent
Fact: Vaccines work by training the immune system to recognize and respond to specific pathogens without causing the actual disease. Some vaccines can cause mild side effects like low fever or soreness, but they do not contain live viruses in a form that causes the disease. The protective immune response reduces the risk of severe illness and complications. Scientific evidence shows vaccines save millions of lives each year by preventing illnesses such as measles, polio, and influenza.
Myth 2: Climate change is not real because weather still gets cold
Fact: Weather refers to short‑term conditions in a specific place, while climate refers to long‑term patterns over decades. Scientists agree that the Earth’s average temperature is rising due to human activities like burning fossil fuels and deforestation. This long‑term warming trend can still include cold days or seasons, but overall global temperatures are increasing, leading to more heat waves, melting ice, and changing precipitation patterns.
Myth 3: You can get COVID‑19 from vaccines
Fact: COVID‑19 vaccines do not contain the live SARS‑CoV‑2 virus that causes the disease, so they cannot give you COVID‑19. Vaccines use pieces of genetic instructions, proteins, or inactivated components to stimulate immunity. Symptoms some people experience after vaccination are signs that the immune system is responding and building protection, not indications of infection.
Myth 4: Eating carrots significantly improves night vision
Fact: Carrots are rich in vitamin A, which is essential for healthy eyesight, but eating large amounts does not give “supernatural” night vision. Severe vitamin A deficiency can lead to poor night vision, so including vitamin‑A‑rich foods in a balanced diet supports normal eye function. However, once your body has enough vitamin A, eating more does not improve night vision above normal levels.
Myth 5: Breaking bones is always painful for life
Fact: A broken bone typically causes pain during healing, but with proper medical care such as immobilization, rest, and follow‑up most people recover fully and do not live with constant pain. Long‑term discomfort can occur in some cases due to complications like improper healing or arthritis, but this is not automatic for every fracture. Modern medicine and rehabilitation greatly improve recovery outcomes.
Myth 6: Cell phones cause cancer because of radiation
Fact: Cell phones emit non‑ionizing radiation, which does not have enough energy to damage DNA or directly cause cancer. Extensive research has not shown a clear link between regular cell phone use and cancer. The World Health Organization and other health agencies continue to monitor studies, but current evidence does not support the claim that typical cell phone use causes cancer.
Myth 7: Humans only use 10 percent of their brains
Fact: This idea is a myth. Brain imaging studies show that nearly all parts of the brain have identifiable functions and are active at different times. While not every region is firing simultaneously, the entire brain has a role in motor control, sensory processing, thinking, memory, and other essential functions.
