Staying up late and excitement could affect the immune system and cause dizziness or short-term hearing problems, a doctor said on Saturday.
Many Taiwanese stay up late and play mahjong or engage in other activities with family members during the Lunar New Year holiday, but this could cause problems, Kaohsiung Medical University’s Chung-Ho Memorial Hospital physician Chang Ning-chia (張寧家) said.

“A lack of sleep and excitement can easily confuse the immune system. If that leads to inflammation of the vestibulocochlear nerve, dizziness could occur,” he said.
Confusion of the immune system could be caused by a sudden change in sleep patterns and could be exacerbated by large differences in day and night temperatures that occur in winter, he added.
The condition is sometimes accompanied by an acute inner-ear infection and temporary hearing loss, Chang said.
However, if people also experience vertigo that persists for more than a few hours, they should seek medical help, he said.
“People should not worry too much if vertigo goes away in a few hours, as it was probably caused by fatigue or a lack of sleep,” he said.
“However, if vertigo lasts for a few days, it might mean that the vestibulocochlear nerve has become inflamed and needs attention,” he added.
Each ear has a vestibulocochlear nerve and they need to send signals to the brain in tandem, Chang said, adding that the signal is disrupted when one of the nerves become inflamed.
Another cause of dizziness might be benign paroxysmal positional vertigo, which happens when a person moves their head rapidly, for example by repeatedly lying down and getting up, he said, adding that the symptom usually goes away on its own.
“People with Meniere’s disease also experience dizziness, vertigo and hearing loss, and could also experience migraines and tinnitus,” Chang said.
“Those with the condition should eat lightly and limit the intake of salt, coffee, pickled foods and fermented dairy products,” he said.
Motion sickness is also common during holidays, due to changes in sleeping and eating patterns, as well as time spent on the road, Chang said, adding that people with the symptom can take motion-sickness medication that contains antihistamines.
“If you feel sick while driving, pull over and close your eyes or stare at something far off to reduce the vestibular eye movement reflex caused by stimulation of the balance system,” Chang said.
“Breathing fresh air also helps,” he said, urging drivers not to eat too much before hitting the road.
China’s Office of the Commissioner of the Ministry of Foreign Affairs in Hong Kong has asked foreign consulates in Hong Kong to submit details of their local staff, which is more proof that the “one country, two systems” model no longer exists, a Taiwanese academic said. The office sent letters dated Monday last week to consulates in the territory, giving them one month to submit the information it requires. The move followed Beijing’s attempt to obtain floor plans for all properties used by foreign missions in Hong Kong last year, which raised concerns among diplomats that the information could be used for
‘ABNORMITY’: News of the military exercises on the coast of the Chinese province facing Taiwan were made public by the Ministry of National Defense on Thursday Taiwan’s military yesterday said it has detected the Chinese military initiating a round of exercises at a bay area in coastal Fujian Province, which faces Taiwan, since early yesterday morning and it has been closely monitoring the drills. The exercises being conducted at Fujian’s Dacheng Bay featured an undisclosed number of People’s Liberation Army’s (PLA) warplanes, warships and ground troops, the Ministry of National Defense said in a press statement. The ministry did not disclose what kind of military exercises are being conducted there and for how long they would be happening, but it did say that it has been closely watching
Vice President William Lai (賴清德) yesterday said that Beijing was trying to “annex” Taiwan, while China said its recent series of drills near Taiwan are aimed at combating the “arrogance” of separatist forces. The Ministry of National Defense earlier this month said that it had observed dozens of Chinese fighters, drones, bombers and other aircraft, as well as warships and the Chinese aircraft carrier Shandong, operating nearby. The increased frequency of China’s military activities has raised the risk of events “getting out of hand” and sparking an accidental clash, Minister of National Defense Chiu Kuo-cheng (邱國正) said last week. Asked about the spurt
Noting that researchers have found that 85 China-based blogs and accounts were spreading a conspiracy theory that a US “meteorological weapon” had caused recent fires in Hawaii, political observers in Taiwan said the nation also needs to be vigilant of Beijing employing similar disinformation campaigns against Taiwan. The untrue content concerning Hawaii was written in 15 languages and disseminated across a myriad of platforms including Facebook, YouTube and X, a report published in Gizmodo said, citing NewsGuard, an online news content ranker. The effort represented the most expansive Chinese informational operation to be uncovered by NewsGuard to date, Gizmodo said. The conspiracy theory
