סיכום קצר
Assess the acute effects of high-temperature exposure (including both daytime and nighttime conditions) on multiple physiological and psychological indicators, including cardiovascular, respiratory, neuropsychiatric, and metabolic functions, along with their potential mechanisms.
תיאור מפורט
This study will be conducted in Hefei, China, as a randomized controlled crossover human exposure trial involving approximately 50 healthy young adults. The primary objective is to systematically evaluate the acute effects of heat exposure-during both daytime and nighttime-on multiple physiological and psychological domains, including cardiovascular, respiratory, neurocognitive, and metabolic functions, and to explor...הצג עוד

מדדי תוצאה ראשיים
מדד תוצאהתיאור המדידהטווח זמן
Heart Rate Variability
Smart Band will be conducted during each exposure session. Time-domain and frequency-domain HRV indices (e.g., SDNN, RMSSD, LF, HF) will be derived to assess autonomic nervous system regulation.
Volunteers will be asked to wear smart band for 24 hours from 6:00 A.M. at the day of intervention to 6:00 A.M. at the next day.
Systolic and Diastolic Blood Pressure
Blood pressure will be measured using an automated sphygmomanometer under standardized resting conditions. Both systolic and diastolic values will be recorded.
Blood pressure will be examined before exposure and immediately (within 10 mins) after the exposure session
Forced Expiratory Volume in 1 Second
Pulmonary function will be assessed using spirometry according to standardized protocols. FEV1 will be recorded as a measure of airway function.
Lung function will be examined before exposure and half an hour after the exposure session
Forced Vital Capacity
Forced vital capacity will be measured via spirometry to evaluate lung volume and ventilatory function.
Lung function will be examined before exposure and half an hour after the exposure session
Interleukin-6
Venous blood samples will be collected and serum IL-6 concentrations will be quantified using enzyme-linked immunosorbent assay (ELISA) to assess systemic inflammatory response.
Blood will be collected 1 hour before and after the exposure session
C-reactive Protein
Serum CRP levels will be measured using high-sensitivity assays as a marker of systemic inflammation.
Blood will be collected 1 hour before and after the exposure session
F2-Isoprostanes
Plasma or urinary F2-isoprostanes will be quantified using validated assays as a stable biomarker of lipid peroxidation and oxidative stress.
Blood will be collected 1 hour before and after the exposure session
Superoxide Dismutase
Serum SOD activity will be measured to evaluate antioxidant defense capacity.
Blood will be collected 1 hour before and after the exposure session
Serum Creatinine
Serum creatinine will be measured using standard biochemical methods to assess renal function.
Blood will be collected 1 hour before and after the exposure session
Urinary Neutrophil Gelatinase-Associated Lipocalin
Urinary NGAL levels will be quantified using ELISA as an early biomarker of acute kidney injury.
Urine will be collected 1 hour before and after the exposure session
Profile of Mood States
Psychological status will be assessed using the validated POMS questionnaire to evaluate mood disturbances.
Scale assessments will be conducted within one hour before and after exposure.

Heart Rate
Heart rate will be continuously recorded during exposure using wearable devices.
Volunteers will be asked to wear smart band for 24 hours from 6:00 A.M. at the day of intervention to 6:00 A.M. at the next day.
Peak Expiratory Flow
PEF will be measured using a portable peak flow meter to assess expiratory function.
Lung function will be examined before exposure and half an hour after the exposure session
Tumor Necrosis Factor-alpha
Serum TNF-α levels will be measured using ELISA.
Blood will be collected 1 hour before and after the exposure session
Monocyte Chemoattractant Protein-1
Serum MCP-1 concentrations will be quantified to assess inflammatory activation.
Blood will be collected 1 hour before and after the exposure session
Glutathione
Reduced glutathione levels will be measured to assess antioxidant capacity.
Blood will be collected 1 hour before and after the exposure session
Blood Urea Nitrogen
Blood Urea Nitrogen will be measured using standard biochemical assays.
Blood will be collected 1 hour before and after the exposure session
Perceived Stress Scale
Perceived stress will be assessed using the validated Perceived Stress Scale questionnaire.
Scale assessments will be conducted within one hour before and after exposure.
