Japan's lifesaver association warns against swimming after drinking alcohol
According to the JLA, approximately 20% of emergency transports from waterfronts involve alcohol consumption. The association warns, "If you drink, don't swim." Ahead of World Drowning Prevention Day on July 25, the Mainichi Shimbun asked an expert about the dangers of swimming while intoxicated.
Alcohol consumption in 20% of waterfront emergencies
"Alcohol intake impairs judgment. Cognitive functions decline, leading to poor decisions such as entering dangerous areas. It also affects the function of the cerebellum, causing loss of balance and unsteadiness, making one prone to drowning even in shallow waters," explains Dr. Nobuya Kitamura, 61, deputy director of Kimitsu Chuo Hospital in Chiba Prefecture and the JLA's medical director.
According to the JLA, in 2024, 41 cases of emergency transport (excluding cases of CPR) were reported among 215 locations nationwide, including beaches where member clubs were active. Of these cases, nine, or 22%, involved alcohol consumption. Four cases were believed to be cardiac arrest due to drowning, with one involving alcohol consumption and later reported as a fatality.
Also recently, a July 7 drowning incident at a beach in the city of Fukuoka involved a man in his 40s who was believed to be intoxicated.
Alcohol bans on beaches, but not at seaside huts
How are municipalities with beaches responding? Since 2014, the Zushi Municipal Government in Kanagawa Prefecture has banned alcohol consumption on Zushi Beach through an ordinance. However, drinking is permitted at beach huts.
The ordinance was put in place to make beaches safer after the "clubification" of beach huts with loud music and drinking became a social issue. Apparently, it was not primarily intended to prevent drowning accidents.
A city official explained that beach huts were exempt from the alcohol ban because "staff can manage the amount of alcohol consumed."
The ordinance also prohibits barbecues and playing music through speakers on the sand. As a general policy, beachgoers who continue to violate the rules after three warnings are advised to leave.
For beach huts, if violations such as "staff serving alcohol to outside customers" occur, warnings and violation notices are issued. If a certain number of these is reached, the municipal government will take disciplinary action such as suspending business operations.
'For the sake of your loved ones'
"If a child is drowning right in front of you, an adult who has been drinking cannot help. 'If you drink, don't swim.' Let's continue to spread this message for the sake of your loved ones," urges Dr. Kitamura.
At the hospital, Kitamura treats patients brought in by emergency transport and those requiring helicopter dispatch. Amid his busy schedule, he plans to volunteer as a lifeguard twice this summer.

Japan's lifesaver association warns against swimming after drinking alcohol
TOKYO -- With summer in full swing, playing in the sea, rivers and pools makes you want to drink cold beverages, but the Japan Lifesaving Association (JLA) is calling on people not to swim after drinking alcohol. According to the JLA, approximately 20% of emergency transports from waterfronts involve alcohol consumption. The association warns, "If you drink, don't swim."

Why are more women in Japan interested in freezing their egg cells?
The Mainichi Shimbun answers some common questions readers may have about women freezing their egg cells in preparation for pregnancy and subsidies for the process. Question: Is the number of women interested in freezing their eggs increasing in Japan? Answer: Yes, more healthy women are interested in freezing their eggs in preparation for future pregnancies. Municipalities and companies are increasingly offering financial assistance for this process. In Tokyo, subsidies of up to 300,000 yen (about $2,070) for the process began being offered in September 2023. As of June 12 this year, a total of 13,314 Tokyoites attended information sessions on egg freezing, with 4,081 applying, indicating significant interest. This differs from egg freezing for medical reasons, such as before cancer treatment. Q: Why do women freeze their eggs? A: As women age, the number of eggs decreases and their quality declines, apparently making pregnancy more difficult. Even if they want to have children in the future, some women have various circumstances, such as wanting to prioritize their work or not having a partner. Egg freezing can be considered one option. Q: Is freezing eggs always beneficial? A: The Japan Society of Obstetrics and Gynecology does not generally recommend it, stating the freezing does not guarantee future pregnancy or childbirth. Risks include side effects from ovulation-inducing drugs and the physical burden of giving birth at an older age. Q: Are frozen eggs actually being used? A: A survey conducted by the Tokyo Metropolitan Government prior to the launch of its subsidy program found that out of 4,567 women who froze their eggs, only 384 used them, with over 70% remaining unused. Among those who used frozen eggs, about 30% -- or 114 women -- became pregnant. It is essential to thoroughly consider the advantages and disadvantages of egg freezing.

The more library books per capita, the fewer residents require nursing care: Japan study
TOKYO -- Researchers in Japan have found that the more public library books a municipality has, the fewer residents require long-term nursing care. Why is this? The Mainichi Shimbun spoke with one of the authors of the research paper titled " Public libraries and functional disability: A cohort study of Japanese older adults." The research was led by Koryu Sato, a lecturer at Keio University's Faculty of Policy Management, and Saeko Otani, a Kyoto University Faculty of Medicine graduate currently in training, using the results of a survey tracking more than 70,000 elderly individuals over seven years, and their study was published in the March issue of the medical journal SSM - Population Health. 'So, what is it about libraries?' Sato, who studied data analysis at the University of Tokyo's Faculty of Economics, holds a master's degree in public health from Harvard University and a doctorate in economics from Waseda University. His specialties are medical economics and social epidemiology. The research began after Otani, then an aspiring doctor and avid reader, expressed a desire to study the relationship between reading and health. However, many previous studies have already explored the connection between reading habits and health. For instance, a lifespan study released by Yale University in 2016 followed 3,635 people aged 50 and above for 12 years, finding that those with reading habits had a 20% lower mortality rate over 12 years compared to nonreaders. Additionally, readers had a 23-month longer period before their survival rate dropped to 80%. Other studies have shown that reading helps prevent cognitive decline. "Reading alone lacks novelty," Sato thought, prompting Otani to suggest, "So, what is it about libraries?" Thus began their unique study on libraries and health. An unexpected correlation They utilized data from the Japan Gerontological Evaluation Study, one of the largest surveys of elderly individuals in Japan. The study analyzed data from 73,138 people aged 65 and older who were healthy in 2013 and lived in 19 cities and towns across the country, tracking them until 2021. During this period, 16,336 individuals, or 22.3%, were certified as needing long-term nursing care. Sato and Otani examined the number of books in public libraries in these 19 municipalities and analyzed their relationship with the number of certifications showing people required long-term care. "In fact, we didn't expect a correlation between libraries and health," Sato admitted. The results were therefore surprising. More books, fewer nursing care certifications? The data analysis revealed a correlation: municipalities with one more book per capita had 4% fewer care certifications, and those with 10 more books per capita had 34% fewer certifications. The national average is about 3.7 books per person, according to the 2024 public library tallies, but in Tokyo's 23 special wards alone, the number ranges from roughly two to eight books, with Chiyoda Ward having the most. Some might question whether municipalities with many library books are wealthier, offering more services, and whether residents are richer and more health-conscious in the first place. However, Sato explained that the results account for demographic and socioeconomic factors. Specifically, they adjusted for factors such as age, gender, years of education, household income, marital status, employment status, social participation, municipal financial strength and population density to ensure these did not influence the results. "What we found is merely a correlation, not a strict causal relationship, so we can't definitively say 'increasing library books will reduce long-term care certifications,'" Sato said. "However, even after removing the influence of various factors, the correlation with the long-term care risk was clear." Health benefits even for nonreaders? Their study also found that while there was a significant correlation between the number of library books and long-term care risks among those with established reading habits, it still existed for nonreaders. This suggests that living in a municipality with many library books may extend healthy life expectancy, even for those who don't read. Why do library books benefit the elderly's health? Sato suggested, "I think that the number of books indicates the library's richness. Having an excellent library nearby is thought to offer physical, cognitive and social participation benefits." He added, "One is the physical effect. Going to the library instead of reading at home contributes to health. Preceding studies show that prolonged sitting is harmful for health, and even without physical exercise, just light walking is beneficial for health." Libraries offer more than just reading The second benefit is cognitive function. Sato explained, "Reading itself is brain training, and unlike regular reading, going to a library offers unexpected book encounters, broadening knowledge. Library events can also stimulate intellectual curiosity." The third benefit is social participation. Sato noted, "Participating in regular activities like hobbies helps maintain cognitive function and reduce mortality, according to previous studies. The Ministry of Health, Labor and Welfare also focuses on 'community places' where elderly people can conduct activities to prevent care and frailty. A large collection of books indicates that the library is large, and it may serve as a hub for community activities. Libraries also have heating and cooling. This potentially bridges economic and living environment gaps for the elderly, such as those with or without air conditioners." Indeed, libraries offer benefits beyond just reading, such as physical and social participation advantages. The key is 'social participation' On weekdays, libraries are filled with elderly men who are "regular library-goers." Previously, they were often negatively viewed in Japan as "people who can't enjoy retirement" or "those without a place in the family." However, knowing that regular library visits reduce long-term care risk might change perceptions of people around them. Interestingly, however, the correlation between the number of library books and health was stronger for women than men in this study. Despite the perception that elderly men dominate library visits, why is this the case? Sato speculated, "It may be due to the degree of 'social participation.'" He added, "While men benefit physically and cognitively from library visits, women overwhelmingly excel in social participation. In terms of this, I think that women likely gain more from library events and group activities." Indeed, "social participation" might be the key to further improving the health of elderly men who frequent libraries. (Japanese original by Ayako Oguni, Opinion Editorial Department)
