“…32 In summer, warmer ambient temperatures are associated with increased water loss through sweating, which triggers thirst and increased water intake. [33][34][35][36][37] The results demonstrated that season did not have a statistically significant effect in children, which is supported in the literature. 38 Just as hotter weather increases water loss, so does physical activity, leading to a greater fluid intake.…”

Aim: Water is critical for human survival, yet water intake equations may not reflect contemporary populations. This research aims to determine the total water intake of a representative Australian population, per kilogram of body weight (mL/kg) and stratified by age and sex. Methods: A secondary analysis of the 2011 to 2013 National Nutrition and Physical Activity Survey (n = 10 146) was conducted. Dietary intake from food and beverages was assessed by a 24-hour recall, with respondent's weight objectively measured. Data were descriptively analysed, with multiple linear regressions used to identify the impact of demographic and physiologic factors on total water intake (mL/kg). Results:The median (interquartile range) daily total water intake per kilogram of body weight for children (2-8 years), adolescents (9-18 years) and adults (19+ years) were 77.1 (57.4-100) mL/kg, 40.4 (29.3-53.4) mL/kg and 35.5 mL/kg (26.1-47.8), respectively. Increasing height and waist circumference were associated with reduced total water intake, with a change of À1.03 mL/ kg (À1.43, À0.618) [coefficient (95% confidence interval)] in children for height and À0.448 mL/kg (À0.484, À0.412) in adults for waist circumference.Similarly, seasonality decreased intake, with greatest reductions in winter [adolescents: À4.11 mL/kg (À6.83, À1.40)]. In comparison, being male, living in rural areas and having a physical occupation were associated with greater intake, by 1.73 mL/kg (0.347, 3.10), 4.74 mL/kg (3.47, 6.00) and 2.82 (trade workers: 1.08, 4.59) in adults, respectively.Conclusions: Total water intake (mL/kg) decreased with age in both sexes. The results highlight possibilities to incorporate other factors into water intake equations to improve their accuracy.

“…Williams et al indicated sebum excretion rate varied with local temperature, that is, sebum excretion rate increased by 10% for every 1°C increase in temperature ( 82 ). A recent study also showed hot environments cause more production of sebum secretion, especially on the forehead ( 83 ). Increased sebum excretion might cause acne to worsening.…”

Background: Acne vulgaris is known as a commonly-seen skin disease with a considerable impact on the quality of life. At present, there have been a growing number of epidemiological, medical, demographic and sociological researches focusing on various influencing factors in the occurrence of acne. Nevertheless, the correlation between environmental factors and acne has yet to be fully investigated. Objective: To assess the impacts of individual, natural and social environmental factors on acne and to construct a framework for the potential impact of built environment on acne. Methods: A thorough review was conducted into the published social demographical, epidemiological, and environmental studies on acne through PubMed, Google Scholar and Web of Science, with reference made to the relevant literature. Results: The influencing factors in acne are classed into four major categories. The first one includes individual socioeconomic and biological factors, for example, gender, age, economic level, heredity, obesity, skin type, menstrual cycle (for females), diet, smoking, cosmetics products, electronic products, sleep quality and psychological factors. The second one includes such natural environmental factors as temperature, humidity, sun exposure, air pollution and chloracne. The third one relates to social environment, including social network and social media. The last one includes built environmental factors, for example, population density, food stores, green spaces, as well as other built environment characteristics for transport. Acne can be affected negatively by family history, overweight, obesity, oily or mixed skin, irregular menstrual cycles, sugary food, greasy food, dairy products, smoking, the improper use of cosmetics, the long-term use of electronics, the poor quality of sleep, stress, high temperature, sun exposure, air pollution, mineral oils and halogenated hydrocarbons. Apart from that, there are also potential links between built environment and acne. Yang et al. Acne Conclusions: It is necessary to determine the correlation between the built environment and acne based on the understanding of the impact of traditional factors (sociology of population and environment) on acne gained by multidisciplinary research teams. Moreover, more empirical studies are required to reveal the specific relationship between built environment and acne.

Background Seborrhea is linked to several medical and mental conditions. Although it is common, effective agents and the standardized sebum level for seborrhea are not elucidated. Aims To determine the efficacy of chitosan particles (CP) formulation on controlling sebum secretion, its extended effects on skin redness and texture after combining with proretinal nanoparticles (CP‐PRN), and a correlation of the clinical grading with sebum levels that affect mental health. Patients/Methods A four‐week clinical trial with forty subjects was conducted. Subjects applied either CP formulation or CP‐PRN during nighttime. Objective measurements including sebum levels, transepidermal water loss (TEWL), skin corneometry, skin redness, and texture were analyzed. Subjects completed a self‐assessment clinical grading of skin oiliness at every visit. Results Both CP and CP‐PRN significantly decreased sebum levels (P ≤ .01) at week 4 compared to baseline. CP also resulted in significant decreases in TEWL (P ≤ .05) and skin corneometry (P ≤ .05) throughout the study. A significant improvement in skin redness was observed with CP‐PRN (P ≤ .01). A moderate correlation between the clinical grading and sebum levels was detected (coefficient of 0.5, P ≤ .001), with a sebum level of 106 μg cm‐2 indicating emotional discomfort. One subject experienced local irritation with the CP‐PRN. Mild pruritic symptoms were reported in both groups. Conclusions Chitosan particles exhibited an interesting anti‐sebum effect. It could be combined with PRN to extend benefits without losing the sebum controlling effect. The clinical grading may be useful in practice due to a modest correlation with sebum levels.
