Group 1 - The common misconception that electric vehicles cannot be driven in the rain due to electric shock risks is debunked. Electric vehicles are designed with waterproof and leak-proof features, typically rated IP67 or higher, ensuring safety during rain [2][5] - All electric vehicles must pass rigorous water immersion tests as per the national safety standards, which include driving in water up to 100mm deep at a speed of 20km/h for at least 500 meters [2] - Additional safety mechanisms in electric vehicles include waterproof circuits and automatic disconnection of high-voltage power in case of anomalies, emphasizing that driving in rain is safe as long as general driving safety is observed [5] Group 2 - The belief that swimming right after eating can lead to leg cramps is clarified. Cramps are more commonly caused by electrolyte imbalance, muscle fatigue, or inadequate warm-up rather than blood flow diversion to the digestive system [6][9] - It is suggested that light meals do not require a waiting period before swimming, while heavier meals should allow for a 30 to 60-minute interval to avoid discomfort [9] - Proper warm-up, hydration, and awareness of individual health conditions are recommended to prevent cramps during swimming [10][11][12] Group 3 - The myth that early use of glasses can worsen children's myopia is addressed. The progression of myopia is linked to eye shape changes rather than the use of corrective lenses [13][18] - Children should be encouraged to have regular eye check-ups and maintain visual health records to manage myopia effectively [18] Group 4 - The claim that removing polyps can lead to more polyps is refuted. Timely removal of certain types of polyps is crucial due to their potential cancer risk, and removal does not cause an increase in polyps [19][24] - New polyps found after removal may be previously undetected or a result of incomplete removal, not a consequence of the removal process itself [24] Group 5 - The notion that shaving facial hair makes it grow back thicker is a common misconception. The thickness of hair is determined by the structure of hair follicles, which is influenced by genetics and hormones, not shaving [25][29] - The perception of increased thickness after shaving is due to the blunt edge of newly cut hair, not an actual change in hair characteristics [29] Group 6 - The belief that drinking vinegar or swallowing food can help dislodge fish bones stuck in the throat is misleading. These methods are ineffective and can potentially worsen the situation by pushing the bone deeper [34][38] - If a fish bone is lodged, it is advised to cough forcefully or seek medical attention if there is significant pain or discomfort [38] Group 7 - The idea that tea residue is beneficial for maintaining teapots is incorrect. Tea residue can harbor harmful substances and microorganisms, affecting both the teapot's integrity and health [39][43] - Regular cleaning of teapots is essential to prevent the accumulation of tea residue and maintain the quality of the tea [43]
