#Hormones

A new meta-analysis has shed light on the complex links between hormonal activity and psychopathic tendencies, raising the prospect of more nuanced approaches to identifying and supporting at-risk youth. The study, published in Psychology & Neuroscience, draws on 25 years of worldwide research and upends some previous assumptions about the biology of personality disorders, with potential implications for prevention and mental health services in Thailand and beyond (psypost.org).

At its core, the research reviewed studies examining the role of endocrine system hormones—such as cortisol, testosterone, estradiol, oxytocin, and dehydroepiandrosterone (DHEA)—in the development of psychopathic traits, especially during the sensitive years of adolescence and early adulthood. The strongest and most consistent finding was a statistically significant association between higher baseline levels of cortisol—the body’s primary stress hormone—and the impulsive, antisocial dimension of psychopathy.

A recently reported side effect of menopause—an acute and sometimes unbearable heightening of the sense of smell—has cast light on an under-recognised health issue affecting women globally, including in Thailand. While hot flashes, mood swings, and sleep problems are well-documented hallmarks of menopause, women are coming forward with distressing accounts of ordinary smells becoming intolerable, wreaking havoc on daily life and relationships. Medical professionals admit that the problem is little understood, and concrete solutions remain elusive, leaving many women without adequate support.

A wave of new research is overturning long-held beliefs about the ovary, showing it as more than just a reproductive organ. Scientists now argue that the ovary plays a central, underappreciated role in shaping women’s overall health and longevity, influencing everything from cardiovascular and bone health to brain function and life expectancy. As groundbreaking findings emerge, experts are calling for greater focus on this overlooked organ—a call that carries important implications for Thai women across the lifespan.

A groundbreaking study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging has revealed that testosterone significantly increases men’s sensitivity to social feedback, reshaping how they experience moment-to-moment self-esteem. The findings promise fresh insights for understanding self-worth, mental health, and social behavior, with potential implications for treatment approaches that resonate in Thai society and beyond (psypost.org).

A team of international scientists set out to unpack testosterone’s intricate role in influencing not just the overall sense of self-worth—what psychologists call “trait self-esteem”—but the more fleeting, variable feelings of self-value known as “state self-esteem.” The research matters deeply for Thai readers, as cultural norms around masculinity, social acceptance, and mental health coverage intersect with emerging scientific understanding, and because mental health struggles linked to low self-esteem, especially among young men, are increasingly noted across Thailand (WHO).

A new wave of international research reveals that while high-intensity interval training (HIIT) delivers sweeping health benefits, it can also disrupt hormone balance—especially if done too often or without proper nutrition and rest. This has sparked growing interest and concern among fitness buffs and health professionals in Thailand, where HIIT classes and early-morning boot camps are booming. Understanding the nuanced impact of high-intensity exercise on the body’s delicate network of hormones is increasingly important for Thai readers eager to maximize the benefits of their workouts without jeopardizing long-term health or well-being.

A wave of recent research is challenging the stereotype that men’s sexual health fades harmlessly with age, with new evidence suggesting that certain sexual health traits may be linked to longevity. Several academic and medical sources now indicate that men who maintain robust sexual health, including frequent sexual activity and normal testosterone levels, may enjoy a significant survival advantage compared to their peers.

The question of whether men who are sexually active or who display high sexual health indicators live longer has attracted scientific attention worldwide. In Thailand, where cultural discussions of male sexual wellbeing are often discreet, such research is particularly resonant as demographic shifts shape health policy priorities. The findings matter for Thai men and their families, integrating a vital aspect of sexual wellness into broader public health.

A groundbreaking new study reveals that the natural ebb and flow of hormones during the reproductive cycle can dramatically reshape the brain and sharpen learning abilities, promising to transform our understanding of cognition—and even hinting at new paths in personalized medicine. Published this week in the journal Neuron and led by researchers at the University of California, Santa Barbara, the research shows that cyclical changes in estrogen not only alter the physical structure of neurons in the memory-related hippocampus but also enhance the brain’s ability to form and maintain mental maps of our surroundings (Neuroscience News).

A groundbreaking study by researchers at Japan’s Fujita Health University has uncovered an unexpected role for brain-derived estrogen in directly regulating appetite and body weight, upending traditional beliefs about how hormones shape our eating habits. Their findings, recently published in The FEBS Journal, not only broaden our scientific understanding but could also open new avenues for treating obesity and overeating—issues of increasing significance in Thailand and around the world (PsyPost).

A growing body of research and expert opinion is highlighting a silent yet serious consequence of excessive abdominal fat in men: a dramatic impact on hormonal balance, sexual health, and fertility. As obesity rates continue to rise—across the world and notably in Asian countries including Thailand—doctors are warning that belly fat is much more than a cosmetic concern. Landmark findings discussed by leading endocrinologists reveal that fat surrounding the waistline acts as an endocrine organ, disrupting testosterone levels and overall male vitality (The News).

Popular health trends recently have seen a surge in interest in so-called “cortisol bellies” and “cortisol faces,” fueled by viral social media posts and a spike in online searches for cortisol-related health advice. These buzzwords, while catchy, attempt to simplify the highly complex biological processes behind how our bodies respond to chronic stress—sometimes sparking unnecessary worry among Thai and global audiences.

Cortisol, often dubbed the “stress hormone,” is produced by the adrenal glands and plays a critical role in helping the body respond to stress. When stress levels rise, so does the production of cortisol, which can affect multiple body systems—regulating metabolism, controlling blood sugar, influencing immune responses, and aiding in fat storage. According to a recent report by the National Post, online searches for information on cortisol, its “trigger foods,” and supposed “cortisol detoxes” have climbed dramatically in the past year, reflecting the growing anxiety about how stress hormones may visibly influence appearance and health (MSN).

For decades, millions of women in Thailand and around the world have relied on birth control pills (“ยาคุมกำเนิด”) not just to prevent pregnancy, but also to help manage acne, painful periods, and hormonal imbalances. But as more young Thais engage in open conversations about relationships and sexuality, an intriguing urban legend has gained traction online: could the pill secretly shape not just your menstrual cycle, but also your feelings towards your romantic partner? Recent expert commentary and scientific research—together with lived experiences—shed light on whether hormonal contraceptives can actually influence who you find attractive or even cause you to fall “out of love” with your partner.
