China’s “Ugly Hour” Push: Viral Hashtag Sparks Nationwide Call for 1‑3 a.m. Bedtimes and New Sleep‑Health Policies

The thread’s origin can be traced to a segment of the popular TV show “初入职场中医季” (TCM Season for Newcomers in the Workplace). In the episode a newly‑minted celebrity was diagnosed with “心肾阴虚,” a condition described in traditional Chinese medicine (TCM) as a deficiency of heart‑ and kidney‑yin, attributed to chronic “熬夜” (late‑night work). A TCM expert on the program underscored that the liver—according to the body’s internal clock—needs to “藏血” (store blood) between 1 a.m. and 3 a.m., a period when it is most active in detoxification and regeneration. The expert warned that staying awake during those two hours keeps the liver “兴奋” (over‑stimulated), paving the way for overthinking, insomnia and a host of other ailments.

That broadcast struck a chord with a generation already accustomed to the “熬夜党” (night‑owl) lifestyle. A flood of user‑generated content followed, ranging from plaintive recountings of waking up feeling “傻” (foolish) and “要猝死” (as if on the brink of sudden death) after a night of only two hours of sleep, to light‑hearted memes about the “correct” way to sleep—some even insisting that “两个枕头才是睡眠的正确打开方式” (using two pillows is the proper way to sleep). A typical comment read: “今晚就扔下手机，早点睡觉！！！,” a pledge to abandon the smartphone and hit the pillow early, posted alongside a poll asking, “#你晚上一般几点睡觉#?” (What time do you usually go to bed?).

The resonance of the hashtag goes beyond anecdote. Analysts of the platform’s sentiment data report an overwhelmingly positive tone, indicating a collective recognition of sleep health as a pressing personal and public issue. Many users have linked their own “熬夜日常” (daily late‑night routines) to the same TCM rationale, reinforcing the belief that a predictable, early‑night schedule can stave off “多思多虑、失眠” (excessive worrying and insomnia). The discourse has thus turned the ancient concept of the “Ugly Hour”—the traditional name for the 1 a.m.–3 a.m. time slot—into a contemporary health campaign.

The ramifications of this movement reach far into the realms of industry, society and policy. In the workplace, the promise of better sleep aligns with research from the International Labour Organization that ties adequate rest to heightened cognitive performance and reduced accident rates, especially in high‑risk sectors such as transportation, construction and healthcare. Companies that have experimented with more flexible shift patterns report fewer fatigue‑related errors when employees are encouraged to respect the 1 a.m.–3 a.m. window. The conversation has also ignited debate about the night‑time economy. Businesses that operate 24 hours—logistics firms, hospitality venues and manufacturing plants—are being prompted to rethink staffing, invest in automation, or redesign schedules so that fewer staff members are required during the liver’s “detox” period.

The health‑tech market is feeling the ripple. Sales of sleep‑tracking wearables, smart pillows and mobile apps offering guided relaxation have surged in the months following the hashtag’s rise. Health clinics report a modest uptick in appointments for insomnia consultations, and the “Chinese Adult Insomnia Diagnosis and Treatment Guide (2023 Edition)”—issued earlier this year—has been cited in a growing number of online threads as a resource for those seeking evidence‑based solutions to chronic sleep loss. While the guide does not single out the 1 a.m.–3 a.m. window, its comprehensive approach to circadian rhythm disorders dovetails neatly with the public’s renewed focus on that specific timeframe.

On the social front, the movement is reshaping everyday life. Parents of school‑aged children note that adhering to the “Ugly Hour” regimen improves daytime mood and academic concentration, echoing longstanding findings that adolescents who sleep at least eight hours are less prone to anxiety and depressive symptoms. In households, the pledge to “throw down the phone and go to bed early tonight” has sparked new family rituals, with members collectively tracking bedtime and rewarding consistent adherence. Experts suggest that these behavioral nudges could have a cascading effect: better rested individuals are less likely to clash in cramped urban apartments, potentially easing the social frictions linked to fatigue‑induced irritability.

Politically, the discourse is nudging legislators toward formalizing sleep rights. In several provinces, labor unions have begun lobbying for statutes that restrict mandatory night work to essential services, while education authorities are piloting policies that discourage after‑school tutoring past 9 p.m., allowing students a window of restorative sleep that includes the critical early‑morning hours. Observers note that countries with stronger sleep protections—such as the Nordic nations—consistently rank higher on productivity and public‑health indices. If China were to codify a “sleep window” into labor law, it could set a precedent for other economies grappling with the fallout of a 24‑hour digital culture.

Scientific research is beginning to catch up with the popular narrative. A 2024 study highlighted that vigilance and behavioral performance hit their nadir between 2 a.m. and 4 a.m., while sleep intensity peaks from 1 a.m. to 7 a.m. These findings echo the TCM claim that the liver is most active during the “Ugly Hour,” albeit from a neurophysiological perspective. Parallel EEG investigations—originally aimed at epilepsy diagnostics—have contributed to a deeper understanding of how brain wave patterns shift across the night, reinforcing the idea that a consolidated sleep stretch during these early hours yields optimal restorative benefits.

Even as the conversation expands, the core message remains simple: sleeping between 1 a.m. and 3 a.m. is not just a cultural superstition but a habit that could safeguard liver health, sharpen mental acuity and reduce societal burdens ranging from healthcare costs to workplace accidents. The viral hashtag has turned an age‑old TCM principle into a modern public‑health rallying point, bridging ancient wisdom with contemporary science, individual experience with collective policy. Whether the trend will translate into formal regulations or remain a grassroots movement, it has already succeeded in making millions of Chinese netizens pause, reflect, and—perhaps most importantly—set their alarms for an earlier bedtime.
