Lifestyle Psychiatry synthesizes and analyzes the extensive evidence supporting the effectiveness of physical activity, diet and nutrition, adequate sleep, and stress management in preventing and treating mental illness.

This book specifically addresses the effectiveness of various lifestyle interventions for a variety of mental illnesses, including depression, anxiety disorders, post-traumatic stress disorder (PTSD), schizophrenia, and addiction, and presents a wealth of evidence supporting the validity of each intervention, regardless of the patient's diagnostic category.

The neurobiological and psychological mechanisms of each intervention are clearly explained, enabling clinicians to educate patients about the intervention's effectiveness and integrate it into their treatment processes.

It also presents a clinical framework for fostering sustainable and practical lifestyle change by addressing strategies that strengthen the therapeutic alliance and motivate patients to actively participate in their own mental health and wellness.

Furthermore, chapters exploring the impact of therapists' lifestyles on clinical practice and the implications of lifestyle psychiatry for health care systems and population mental health delve into the key role this emerging discipline can play in a sophisticated, holistic approach to promoting the mental health of individuals and societies.

Chapter 1: Introduction to Lifestyle Psychiatry
·Lifestyle psychiatry is a branch of lifestyle medicine that focuses on managing mental illness through an integrated and holistic approach to health.
·In medicine, lifestyle refers to physical activity, diet and nutrition, sufficient sleep, and stress management.
·Lifestyle psychiatry goes beyond the traditional biopsychosocial model to help manage mental illness through specific recommendations for exercise, diet, sleep, and mindfulness practices.
·Lifestyle interventions can complement drug and psychotherapy by positively influencing cognitive function, motivation, and self-efficacy.
·Lifestyle interventions have been proven to have neurobiological and epigenetic effects, and physical activity in particular is known to be the most powerful intervention for promoting synaptic plasticity.
·Lifestyle psychiatry provides opportunities to find balance in life and immerse yourself in nature.

-Chapter 2 Physical Exercise and the Brain
·The link between physical strength and cognitive function appears to stem from common factors that led to improvements in both functions during human evolution.
·There is strong clinical trial evidence that aerobic exercise can significantly improve brain function in both psychiatric patients and the general population.
·Evidence that resistance exercise affects the brain is still in its infancy, but it holds great promise as a complementary exercise intervention for improving cognitive function.

Chapter 3: Physical Exercise for the Management of Major Depressive Disorder
·Physical activity is beneficial for patients with major depressive disorder and other depressive disorders in several ways, including alleviating mood symptoms, preventing other diseases, and improving psychosocial functioning.
·Although it has been reported to be effective even with a low level of activity, the symptom improvement effect tends to be more pronounced as the exercise intensity increases.
·Medical and public health professionals recognize the changing motivational processes in patients and address common barriers to exercise performance.
We also provide mental health education on evidence-based strategies and utilize behavioral activation techniques.
This can help promote physical activity in patients with depression more effectively.
·Future research is needed to examine the relationship between depression and physical activity in patients with postpartum depression, bipolar disorder, and diverse socioeconomic and demographic backgrounds.

Chapter 7: Physical Exercise for Cognitive Protection and Management in Neurocognitive Disorders
·The various benefits of physical activity and exercise also apply to the prevention and management of neurocognitive disorders such as mild cognitive impairment and Alzheimer's disease.
·Exercise has positive effects such as increasing brain volume, reducing beta-amyloid accumulation, and improving cognitive function.
·The mechanisms by which exercise positively affects cognitive function are proposed to include promotion of neurogenesis, enhancement of synaptic plasticity, activation of the neurotransmitter system, and stimulation of the secretion of growth factors such as brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF).
·The American College of Sports Medicine (ACSM) and American Heart Association (AHA) physical activity guidelines for older adults build on existing federal guidelines by focusing on activities that improve balance and flexibility, while further emphasizing the importance of activity planning and exercise prescription.

Chapter 9: Physical Activity for Managing Attention Deficit Hyperactivity Disorder
·Physical activity helps improve attention function and alleviate symptoms of attention deficit hyperactivity disorder.
·Children with attention deficit hyperactivity disorder tend to be less physically active than their peers.
In adults, the prevalence of obesity and cardiovascular disease is high, which can lead to long-term health problems.
Interventions to promote physical activity and reduce sedentary behavior in children and adults are promising approaches that could be included in comprehensive treatment plans for ADHD.


-Chapter 13 Diet and Nutrition Management for the Prevention and Supportive Treatment of Mental Illness
·Diet and nutrition can influence the risk and symptoms of various mental disorders.
·Key mechanisms include the effects of diet on neuroinflammation and oxidative stress.
Deficiencies in certain nutrients may affect the onset and severity of mental illness.

Chapter 15: Managing Sleep for Optimal Performance, Brain Function, and Mental Health
·The need for sleep enhancement or the sleep enhancement process (process S) gradually accumulates with longer wakefulness and greater daytime activity.
This increased need for sleep helps you fall asleep more easily and maintain deeper sleep.
·The circadian rhythm or circadian wakefulness process (process C) changes in approximately 24-hour cycles, increasing the need for sleep by keeping us awake during the day and decreasing the need for sleep by keeping us asleep at night.
This rhythm is influenced by zeitgebers, circadian rhythm-regulating stimuli such as food, physical activity, and especially light.
·The sleep of healthy adults alternates between light and deep sleep stages several times throughout the night, and is characterized by longer periods of non-rapid eye movement (NREM) sleep in the first half.
·The most common sleep problems in psychiatric disorders are insomnia and poor sleep hygiene, but hypersomnia, circadian rhythm disturbances, obstructive sleep apnea, and restless leg syndrome can also occur.
Cognitive behavioral therapy (CBT) is recommended as the most effective treatment for insomnia and poor sleep hygiene.
·The most effective CBT techniques for improving insomnia include bed time restriction, which limits the amount of time spent in bed to the amount of time actually spent sleeping, and bed-sleep reassociation training, which uses the bed only for sleep.
·Practicing how to calm your mind and relax your body will help you sleep much more comfortably than forcing yourself to fall asleep.
Forcing yourself to sleep is ineffective and counterproductive because it keeps your body and mind awake, making it difficult to fall asleep.

Chapter 18: Physicians' Lifestyles and Health Promotion Behaviors
·Many people cite their doctors as their primary source of information about a healthy lifestyle.
These patients are more likely to practice a healthy lifestyle when their doctor recommends it.
·Physicians and medical students who personally practice healthy habits are more likely to recommend these habits to their patients, and physicians who personally perform preventive screenings or interventions tend to see more patients who adhere to preventive health management.
·The recognition that medical schools must actively cultivate healthy doctors is becoming increasingly clear.
·The relationship of 'healthy doctors = healthy patients' promotes the evaluation and support of the positive impact of a prevention-oriented healthcare system on doctors' health.
