    1. It should be noted that studies across different populations have found significant gender and age differences in SAD symptoms (44, 45), SAD is more prevalent among individuals with a predisposition for deep depression.

      Serotonin, a key mood-regulating neurotransmitter, is strongly influenced by sunlight. Its production and receptor activity decrease in low-light conditions, contributing to winter drops in serotonin levels, and the development of SAD, with symptoms varying by age and gender. This demonstrates that reduced light exposure can trigger negative emotional states through lowered serotonin activity.

    2. A study by Cereda et al. (38) pointed out that in winter, reduced sunlight exposure and lower vitamin D levels may induce depressive symptoms in individuals with Seasonal Affective Disorder (SAD), as well as conditions like bipolar disorder.

      Vitamin D, which is mainly produced through UVB exposure from sunlight, decreases during cloudy weather and winter, and low vitamin D levels are strongly linked to depression, fatigue, negative emotions, and even greater suicide risk, while supplementation has been shown to improve mood and reduced inflammation. This shows how adequate vitamin D is essential not only for physical health but also for maintaining psychological well-being and life satisfaction.

    3. Studies have shown that melatonin influences the production and release of neurochemicals such as serotonin, dopamine, and endorphins, which are associated with happiness and well-being (36).

      Melatonin, a light-sensitive hormone that rises in darkness and regulates the sleep wake cycle, also influences happiness by affecting key mood-related neurochemicals like serotonin and dopamine, and its balance can be disrupted by factors such as artificial light, caffeine, alcohol, and stress, highlighting its important role in both emotional regulation and overall well-being.

    1. The degree of air pollution can significantly influence individual schedules and life satisfaction, especially for vulnerable groups such as children, the older adult, and those with respiratory or cardiovascular conditions.

      Large-scale social media analyses and other studies show that higher air pollution reliably lowers happiness—even beyond its physical health effects—likely due to aesthetic unpleasantness, sensory discomfort, and health-related anxieties, with especially strong impacts on vulnerable groups such as children, older adults, and people with respiratory or heart conditions.

    2. Well-being is not only the core pursuit of human life but also an important predictor of various positive life outcomes, such as longevity, creativity, quality of interpersonal relationships, and work efficiency (1).

      Well-being is deeply intertwined with weather conditions, a relationship long noted in daily life and literature. Modern research on this topic has rapidly expanded, revealing through multidisciplinary studies how weather influences well-being via physiological, psychological, and social pathways.

    1. 4.2.2 The effects of landscape type on fatigue recovery various among students with different major.

      Environmental majors experience stronger physical and psychological recovery from natural environments than non-majors because of their education, familiarity, ecological awareness, and emotional connection to nature enhances their ability to relax and recover. Suggests that nature based mental health interventions should account for students' backgrounds and environmental values

    2. 4.2.1 Juniors exhibit faster recovery and more positive preference than freshmen.

      Juniors experience stronger psychological and physical restoration from natural environments than freshman, possibly due to the fact that they are older, more emotionally mature, have better coping skills and social support, and therefore better able to benefit from nature. Suggests that age and developmental stage should guide how schools design nature-based mental health programs.

    3. 3.1 Physiological response of viewing different landscape types

      This study shows that visual exposure to natural environments, especially forests and water, produces measurable physiological relaxation: • nature images lower systolic BP • forest images lower diastolic BP • water images lower HR Suggests that different types of natural scenes have different calming effects, and body overall responds physiologically to nature in ways that promote relaxation and reduce stress.

    1. Health care is an area that will likely see many innovations. There are already multiple research prototypes underway looking at monitoring of one’s physical and mental health. Some of my colleagues (and myself as well) are also looking at social behaviors, and how those behaviors not only impact one’s health but also how innovations spread through one’s social network.
