A recent study from the University of Montreal shows that caffeine consumed in the hours before bed can alter the brain’s sleep recovery, especially in younger adults. The research found more wake-like brain activity during sleep when caffeine is used in the evening, potentially hindering both mental and physical restoration. For Thailand’s coffee- and tea-loving society, these findings raise timely questions about late-day caffeine and its impact on well-being.

In Thailand, iced coffee and bubble tea after dinner are common choices for students and professionals burning the midnight oil. The study, published in Nature Communications Biology in 2025, indicates that even moderate evening caffeine can noticeably change sleep rhythms, keeping the brain more alert and less restorative. The effect is strongest among people in their 20s due to age-related differences in brain chemistry.

A groundbreaking new study from the University of Montreal has revealed that caffeine, the world’s most widely consumed stimulant, tangibly disrupts the brain’s recovery during sleep—especially in younger adults. The researchers found that consuming caffeine in the hours before bedtime leads to more complex, “wake-like” brain activity at night and could hamper both mental and physical restoration, raising crucial questions for Thailand’s coffee- and tea-loving society regarding nighttime caffeine consumption and its impact on well-being (Neuroscience News).

A wave of online discussion and emerging expert commentary has thrown the spotlight on a little-known but deeply felt emotional response that many people with attention deficit hyperactivity disorder (ADHD) are now recognizing as a shared experience: rejection sensitive dysphoria (R.S.D.). Although not officially classified in psychiatric manuals, R.S.D. is described as an intense or overwhelming reaction to actual or perceived criticism, rejection, or failure—a feeling likened to a “balloon popping” by TikTok creators and capturing the imagination of millions on social media platforms source.

A growing online conversation and expert commentary are bringing attention to rejection sensitive dysphoria (R.S.D.), a powerful emotional response some people with ADHD experience when facing criticism or perceived failure. Although not yet a formal diagnosis in major manuals, ADHD communities describe R.S.D. as an intense, sudden shift in mood—like a balloon popping—triggered by real or imagined rejection. This topic has captivated millions on social media and sparked wide conversations about mental health.

The pervasive presence of digital screens in the lives of adolescents is increasingly seen as a contributing factor to sleep disruptions and rising depression rates, particularly among teenage girls. A recent study published in PLOS Global Public Health by researchers from the Karolinska Institutet in Sweden delves into these associations, emphasizing that reducing screen time could alleviate mental health issues in young people.

The research tracked over 4,810 Swedish teenagers, aged between 12 and 16, over a one-year period. The study meticulously documented their screen usage, sleep patterns, and depressive symptoms. The findings were clear: increased screen time was linked to poorer sleep quality and timing, which in turn predicted depressive symptoms.

A large Swedish study links rising teen depression to heavy screen use and disrupted sleep. Researchers from Karolinska Institutet tracked thousands of adolescents and found that more screen time was associated with poorer sleep, which in turn predicted higher depressive symptoms.

The study followed 4,810 Swedish youths aged 12 to 16 over one year. It carefully measured daily screen use, sleep patterns, and mood. Results showed a clear pattern: longer screen time correlated with later bedtimes and lower sleep quality, and these sleep problems were connected to greater depression.
