Winter is a season with a high incidence of colds, and people may feel dizzy and their reaction agility significantly decreases after catching a cold, which affects driving safety. The traffic management department reminds drivers that colds can have a negative impact on driving safety, especially the harm of taking cold medicine while driving cannot be ignored. When catching a cold, it is necessary to consider whether to drive or not based on the degree of physical discomfort. It is also important to fully understand which cold medicines are not suitable for driving after taking them, in order to avoid accidental "medication driving" and endangering the safety of oneself and others during travel. It is understood that "drug driving" refers to the behavior of a driver who continues to drive after taking medication that affects safe driving behavior. After taking these drugs, adverse reactions such as drowsiness, drowsiness, distraction, dizziness, tinnitus, unclear vision, and delayed response may occur, which can easily lead to accidents. Some drugs, like alcohol, can weaken human cognitive clarity and judgment. Safe driving requires ensuring basic brain functions, including cognition, understanding, attention, balance, memory, small muscle motor ability, coordination, etc. Both drugs and alcohol can weaken the aforementioned abilities to varying degrees, but everyone's tolerance and metabolic rate are different, so the amount of dangerous drunk or drug driving varies from person to person. The World Health Organization has listed seven categories of drugs that may affect safe driving after use, including anti allergic, antidepressant, and antihypertensive drugs, and believes that driving should be prohibited after taking these drugs. Many cold medicines are among them, which can easily cause symptoms of drowsiness. Commonly used cold medicines often contain antihistamines, which have a significant inhibitory effect on the central nervous system. They often have side effects such as drowsiness, dizziness, headache and fatigue, tremors, tinnitus, and hallucinations, which can cause inattention and lack of sensitivity. In addition, antipyretic and analgesic drugs can have a certain impact on driving. Some cough and analgesic drugs contain alcohol and can affect the central nervous system. After taking such drugs, it is recommended not to drive. For common cold, it is better to choose traditional Chinese patent medicines and simple preparations or western medicine without antihistamine ingredients. If purchasing from a pharmacy by oneself, it is necessary to carefully read the instructions or product labels of the drug, especially to see the adverse reactions, precautions, dosage, contraindications, etc. In addition, do not overdose or repeat medication, and pay attention to drug interactions. Medications that are known to have adverse reactions but must be taken should be taken in half before driving, and then replenished in full when resting. The traffic management department stated that "drug driving" has caused many traffic accidents, and reminded drivers to understand their own physical condition and ensure that they can only drive outside when their physical conditions permit.
