A new study from Uppsala University shows that sleeping only four hours a night for three consecutive nights can trigger rises in blood markers linked to future heart disease. The finding is especially relevant for Thai readers in a country where late work hours, exams, and city noise disrupt sleep. Bangkok’s vibrant pace makes this a timely public health concern, given rising heart disease rates across the nation.

In Thailand, sleep disruption is common among workers in hospitality, transport, and healthcare, and researchers note that chronic short sleep is a growing risk factor. Thailand’s Ministry of Public Health reports heart disease as a leading cause of death, highlighting the potential impact of sleep on nationwide health outcomes. Data from Thai health institutes show many adults struggle with sleep quality, a trend shared with the Swedish participants in the study, who were healthy young men at baseline.

A groundbreaking new study led by researchers at Uppsala University finds that sleeping just four hours per night for three consecutive nights—something many young people and shift workers might dismiss as “a rough week”—can measurably increase biological markers known to signal future heart disease risk. Alarmingly, this effect appeared in healthy young men after only short-term sleep deprivation—raising important health questions for Thais in an era where late nights and round-the-clock connectivity have become normal, especially in vibrant cities like Bangkok.
