A wave of new research warns that exercising too late in the day—especially if it’s high-intensity—could be robbing you of restorative sleep. As more Thais embrace fitness culture and nighttime gyms gain popularity in Bangkok and beyond, a landmark study of nearly 15,000 people has highlighted how the timing and intensity of your evening workout could be the culprit behind tossing, turning, and groggy mornings (Fortune, Nature Communications). For many, it’s a challenge to find gym time amid work, family, and Bangkok’s notorious traffic jams, pushing workouts close to bedtime. But these new findings have direct and important implications for health-conscious Thais.

A major international study warns that late-evening, high-intensity workouts can disrupt restorative sleep. As fitness culture grows in Thailand and nighttime gyms multiply in Bangkok and beyond, new findings suggest finishing exercise too close to bedtime may cause difficulty winding down and groggy mornings. This matters for busy Thai professionals, students, and families juggling work, commuting, and social obligations.

Regular physical activity remains a cornerstone of health, endorsed by doctors and Thailand’s Ministry of Public Health for its role in reducing disease risk, boosting mood, and supporting sleep. Yet the latest research from Monash University challenges the blanket “any exercise is good” mantra when sleep is the goal. The study followed nearly 15,000 adults using fitness trackers over a year, analyzing millions of nights of data. The key message: completing high-intensity workouts within four hours of sleep correlates with later sleep onset, shorter duration, and poorer sleep quality. Lighter activities such as walking or stretching, if done late, showed less impact on sleep.

Castor oil, orละหุ่ง, sits at the crossroads of Thai traditional healing and contemporary science. Derived from Ricinus communis seeds, its legacy spans centuries—from household remedies to topics of current pharmacological research. In Thailand, interest in castor oil grows as ancient practices intertwine with evidence-based medicine, offering a case study in how tradition can inform modern healthcare.

Thai households have long used castor oil for a range of purposes. Traditionally applied topically for skin inflammation, muscle and joint pain, and minor wounds, the oil is also a common laxative in internal remedies. In rural communities, castor oil has been part of family healing rituals, carrying both practical use and cultural caution about its potent properties. The plant is familiar across Thailand’s tropical landscape, with regional names such as ละหุ่งขาว and ละหุ่งแดง signaling its presence in local folk knowledge.

In the landscape of Thai traditional medicine, few herbal remedies have achieved the enduring prominence of castor oil, or “ละหุ่ง.” Extracted from the seeds of Ricinus communis L., castor oil’s legacy spans centuries—pivoting from local wisdom to a remedy that has generated considerable interest among researchers and health enthusiasts in Thailand and around the world. As ancient applications increasingly intersect with medical science, castor oil emerges not only as a fascinating artifact of cultural heritage but also as a subject of rigorous pharmacological inquiry.
