People who experience dizziness or nausea whenever they are at work might have a medical condition that is treatable with medication and exercise, a psychiatrist in Kaohsiung said.
The condition, in which some people feel sick at work, but then feel better as soon as they leave, might go undiagnosed, and in some cases they might be misdiagnosed as having autonomic dysfunction, Prospect Clinic psychiatrist Tseng Ping-tao (曾秉濤) wrote in an article in the Chinese-language Liberty Times (the Taipei Times’ sister newspaper) yesterday.
In most cases, the condition is related to migraines, and is often caused by vestibular migraines, Tseng said.
In many cases there is something at the workplace affecting the person that cannot be solved, he said.
For example, a person might be dealing with poor relationships with coworkers or even emotional abuse, or they might often be told at the last minute that they need to put in overtime, he said.
Constant pressure in the work environment, combined with an imbalance in a person’s calcium channels, can reach a critical point, causing neurons in the brain stem to send out electrical pulses, which lead to nausea, he said.
When these pulses pass through the inner ear they can cause tinnitus and dizziness, and when they pass through the spinal cord they can cause numbness in the limbs and muscle aches, he said.
They can also cause headaches and blurred vision when they pass through the brain, he said.
The condition can be “memorized” by the nervous system so that it reoccurs at the same time every day, he said, adding that it might even occur on a person’s day off, although with less intensity.
The condition can be treated in a manner similar to how migraines are treated, with patients given painkillers and medication to combat vertigo, he said.
They might also be told to take beta blockers or gamma aminobutyric acid — a medication used to relieve anxiety — every day before he onset of symptoms to break the cycle, he said.
Those with the condition might also be given botulinum toxin injections, which can help them relax, he said.
Regular exercise is also helpful, and people can achieve a healthy level of exercise by walking or cycling to and from work, he said.
As other pre-existing conditions can also lead to dizziness in the workplace, people who suspect they have the condition should visit a doctor, he said.
CAUTION: Based on intelligence from the nation’s security agencies, MOFA has cautioned Taiwanese travelers about heightened safety risks in China-friendly countries The Ministry of Foreign Affairs (MOFA) yesterday urged Taiwanese to be aware of their safety when traveling abroad, especially in countries that are friendly to China. China in June last year issued 22 guidelines that allow its courts to try in absentia and sentence to death so-called “diehard” Taiwanese independence activists, even though Chinese courts have no jurisdiction in Taiwan. Late last month, a senior Chinese official gave closed-door instructions to state security units to implement the guidelines in countries friendly to China, a government memo and a senior Taiwan security official said, based on information gathered by Taiwan’s intelligence agency.

Taiwan Semiconductor Manufacturing Co (TSMC), the world’s largest contract chipmaker, said yesterday that it is looking to hire 8,000 people this year, at a time when the tech giant is expanding production capacity to maintain its lead over competitors. To attract talent, TSMC would launch a large-scale recruitment campaign on campuses across Taiwan, where a newly recruited engineer with a master’s degree could expect to receive an average salary of NT$2.2 million (US$60,912), which is much higher than the 2023 national average of NT$709,000 for those in the same category, according to government statistics. TSMC, which accounted for more than 60 percent
Tung Tzu-hsien (童子賢), a Taiwanese businessman and deputy convener of the nation’s National Climate Change Committee, said yesterday that “electrical power is national power” and nuclear energy is “very important to Taiwan.” Tung made the remarks, suggesting that his views do not align with the country’s current official policy of phasing out nuclear energy, at a forum organized by the Taiwan People’s Party titled “Challenges and Prospects of Taiwan’s AI Industry and Energy Policy.” “Taiwan is currently pursuing industries with high added- value and is developing vigorously, and this all requires electricity,” said the chairman
