Ambient air temperatures in the Pacific have broken record highs in 2024. Solutions are needed to build heat resilience in communities and adapt to increasing heat from climate change. Sunlight-reflecting cool roof coatings may passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions in the Pacific are susceptible to increased heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are experienced in communities that are least able to adapt to heat exposure. By reducing indoor temperatures, cool roof use can promote physical, mental and social wellbeing in household occupants. The long-term research goal of the investigators is to identify viable passive housing adaptation technologies with proven health benefits to reduce the burden of heat stress in communities affected by heat in Niue. To meet this goal, the investigators will conduct a cluster-randomized controlled trial to establish the effects of cool roof use on health, indoor environment and economic outcomes in Niue.
NCT07381881
The objective of this clinical trial is to assess whether hydration with gelled water (GEL-AID) can improve fluid intake and reduce cases of dehydration, as well as the incidence of urinary and respiratory infections in institutionalized elderly individuals in nursing homes. The main question this trial aims to answer is: • Do institutionalized elderly individuals hydrated with GEL-AID increase their daily fluid intake and reduce the incidence of dehydration, urinary infections, and respiratory infections? Participants: The control group will follow the center's usual hydration plan. Individuals with swallowing difficulties will receive thickened liquids and/or gelatin, while those without swallowing difficulties will be hydrated with unmodified liquids or gelatin. The intervention group will receive hydration with GEL-AID. For participants with swallowing difficulties, thickened liquids and gelatin will be replaced by GEL-AID, with texture adapted to their needs. Those without swallowing difficulties will receive unmodified liquids and GEL-AID instead of gelatin.

Cardiovascular diseases (CVD) are the leading cause of death in middle- and high-income countries, according to data from the World Health Organization (WHO). Epidemiological studies have associated low water intake and underhydration with diabetes, chronic kidney disease, and an increased risk of CVD. Similarly, the prevalence of chronic metabolic dysfunction is increasing dramatically worldwide, becoming both a significant public health concern and a global economic burden. Reports from the WHO indicate that the number of people with diabetes worldwide has risen from 108 million in 1980 to 422 million in 2014, representing 8.5% of adults. Therefore, there is an urgent need to identify modifiable risk factors that could help prevent metabolic dysfunction and mitigate the epidemic of type 2 diabetes (T2D). Evidence suggests that the hormone arginine vasopressin (AVP) may play a key role. AVP is the primary hormone responsible for regulating body fluid balance; however, increased AVP secretion, such as under conditions of low water intake, appears to be a risk factor for developing diabetes. Increasing water intake may represent a simple and cost-effective way to improve glucose regulation and cardiovascular health. However, many individuals do not prefer drinking plain water, and although beverages with high sugar content may promote greater fluid intake, they also contribute additional calories that can negatively impact body weight and overall health. Thus, the central research question of this study is whether improving hydration with non-sugar-sweetened beverages can provide equivalent benefits for hydration and health outcomes in adults. Aim 1: To explore the association between habitual fluid intake and fluid preferences (water and non-sugar-sweetened beverages), hydration biomarkers, and health outcomes in normal-weight and obese adults. Aim 2: To compare the impact of increased total water intake, provided as plain water or non-sugar-sweetened beverages, on hydration, cardiovascular health, and glucose regulation in normal-weight and obese adults.

Caffeine is known to enhance physical and mental performance, but few beverages combine caffeine with electrolytes and carbohydrates to enhance exercise performance. This study evaluates a caffeinated electrolyte-glucose drink's effect on endurance, strength, and cognition. Using a repeated-measures, cross-over design, 20 trained cyclists will complete one familiarization and four randomized 3-hour experimental trials (Liquid I.V.™ Energy Multiplier, Hydration Multiplier, Sugar-Free Hydration Multiplier, and water). Each trial includes 2 hours of cycling in a warm environment (32ºC), followed by strength and cognitive assessments. Cycling performance, capillary blood, urine, and expiratory gases will be collected.
NCT06206434
In elderly patients with cardiac diseases, changes in cardiovascular physiology diminish cardiovascular reserve and predispose to significant hemodynamic instability after spinal anesthesia; hence, such patients could be at risk of postoperative complications. Additionally, point of care ultrasound (POCUS) and transthoracic echocardiography (TTE) are used in clinical practice to evaluate cardiovascular hemodynamics. Inferior vena cava (IVC) and its collapsibility index (CI) have been used in clinical practice for the prediction of post-spinal hypotension. Specifically, the dIVCmax-to-IVCCI ratio \< 48 showed high diagnostic performance among other indices in the prediction of post spinal hypotension in elderly patients with cardiac diseases undergoing proximal fracture repair. Elderly patients also experience high likelihood of dehydration. According to the above findings, the investigators hypothesized that fluid co-loading immediately after spinal anesthesia can lower the incidence of spinal-induced hypotension in dehydrated patients. . For this reason, it is prospectively evaluated echocardiographic indices of the LV and the right ventricle (RV), as well as of the IVC prior to spinal anesthesia in elderly patients with proximal femur fractures who had low LV-EF and increased ratio of BUN-to-creatinine.
NCT06858904
It is well established that post-exercise rehydration with electrolyte solutions is more effective than plain water. However, most commercially available drinks are high in electrolytes but lack some essential trace minerals. This study aims to examine the impact of a higher-electrolyte sports drink compared with a low-electrolyte, trace-mineral-rich solution and water on the time course and extent of rehydration after exercise-induced dehydration.
NCT06259799
Approximately 60% of males and 40% of females do not meet current fluid intake recommendations, which is associated with adverse health consequences such as obesity, diabetes, and chronic kidney disease. Newer technologies have been designed to promote fluid intake. "Smart Water Bottles" use mHealth technology to capture fluid intake behaviors automatically and provide cues to encourage fluid consumption. Studies using Smart Water Bottles have helped some individuals increase fluid intake to help reduce kidney stone formation. However, limited research has assessed the efficacy of this technology on improving fluid intake in college students. College is a time with the potential to form healthy habits that carry into adulthood. Previous work has also identified daily changes in morning urine color, thirst perception, and body mass, as simple, inexpensive indicators of daily fluctuations in water balance. Tracking changes in these metrics has the potential to provide participants with evidence of adequate or inadequate fluid consumption. Thus, the combination of prompting from a smart water bottle, as well as daily self-monitoring changes in hydration status, may encourage college students to increase daily fluid consumption.

This randomized controlled trial aims to evaluate the impact of a mobile-friendly, web-based hydration tracking application (named "SIVI") on hydration-related knowledge, attitudes, and behaviors in older adults. Inadequate fluid intake is a common and modifiable risk factor for dehydration in the elderly, leading to increased morbidity, hospitalizations, and functional decline. However, many older individuals forget to drink fluids or face barriers such as fear of incontinence, mobility limitations, or cognitive challenges. This study will include 70 community-dwelling older adults aged 65-84 years, recruited from a Family Health Center. Participants will be randomly assigned to either the intervention or control group. The intervention group will use the SIVI application for two months. The app is specially designed for older adults and includes features such as personalized fluid goals, reminders, hydration education modules, feedback, and a user-friendly interface with large fonts and high contrast. Participants will log their daily fluid intake, receive motivational messages, and access videos and information about healthy hydration habits. A water bottle will be provided to standardize measurement across groups. The control group will receive only routine care. Both groups will complete questionnaires measuring demographics, hydration knowledge, attitudes, behaviors, and fluid consumption habits at baseline, one month, and two months. Data collection will be conducted face-to-face by the researcher, and analysis will be performed using SPSS 22.0. Statistical tests will include descriptive statistics, Shapiro-Wilk for normality, chi-square for categorical data, and t-tests and ANOVA for comparisons over time. The results are expected to show that the SIVI application improves older adults' hydration knowledge, fosters positive attitudes, and promotes healthy fluid intake behaviors, thus supporting self-management of hydration and potentially reducing dehydration-related health risks.

NCT05380089
Greater muscular strength and power are relevant qualities for athletic success and decreased injury rate. It is known that dehydration impairs muscular strength and power, although the explanation for this association is not entirely clear. Besides morphological factors, strength production also depends on neural factors which in turn can be affected by dehydration. Some studies tested the effects of dehydration on neuromuscular function using electromyography (EMG) analysis. However, there is no consensus among those studies. Additionally, exercise may disturb water balance. This can further lead to dehydration if the athlete does not properly rehydrate. In this sense, the scientific evidence has identified people who are considered low drinkers that may be more susceptible to cellular shrinkage, potentially impairing health and performance. Thus, it would be expected that athletes regularly exposed to lower amounts of water intake would have beneficial effects in both performance and health if higher water ingestion was promoted, namely an improved neuromuscular function via enhanced cellular hydration. However, any potential benefit of increasing water intake on neuromuscular function is still to be determined using well-designed experimental studies and state-of-the-art methods. Lastly, there is no consensus regarding the diagnosis of dehydration in athletes. The identification of simple indices to measure dehydration in athletes is crucial as many may be inaccurately diagnosed.
NCT06084702
The low fluid intake in combination with a high intake of sugar-sweetened beverages (SSB) by children is a significant concern among public health professionals. Therefore reformulation of existing commercially available beverages has been suggested as one of the strategies to change SSB beverage behaviors of children. It has been suggested that lack of flavor in plain water is one of the factors of low water intake in children. Therefore, the addition of a flavor to a low-carbohydrate beverage might increase and facilitate the voluntary fluid intake in children, and result in more effective rehydration during and after exercise. The present study aims to examine if a lower sugar flavored water will improve voluntary hydration in children that perform multiple exercise bouts within a period of 3 hours.
NCT06338501
Known as "Thai boxing," Muay Thai utilizes a combination of upper limb strikes (such as punches and elbow strikes) as well as lower limb strikes (such as kicks and knee strikes), and is thus referred to as the "art of eight limbs." It is practiced worldwide and is a prominent discipline in many mixed martial arts (MMA) training camps. In this sport, training load control involves monitoring and adjusting the quantity and intensity of training according to each athlete's capacity. In the context of combat sports, such as Muay Thai, heart rate variability (HRV) and assessment of body composition by bioelectrical impedance analysis can be used as tools to evaluate training responses. Additionally, HRV can also serve as a tool for assessing recovery after training or competition. If HRV does not return to baseline after training or competition, it may be a sign that the athlete is not fully recovered and may need more time to recuperate before returning to training or competition. Due to the absence of studies in the literature that have assessed a possible association between HRV and dehydration and rehydration processes in amateur Muay Thai athletes, it becomes essential to evaluate this correlation. Given the growing interest in practicing Muay Thai in gyms, assessing the sympathetic-vagal balance, body composition, and performance of these athletes becomes of utmost importance. Therefore, the aim of this study is to investigate the relationship between dehydration indicators, HRV parameters, and performance in the frequency speed kick test (FSKT). Participants will be assessed before and after an eight-week training program, conducted three times a week. Assessments will include resting HRV measurement and FSKT; in addition, bioimpedance will be used to estimate the body composition of participants pre- and post-training. It is expected that the results will reveal changes in HRV, performance, and body composition of the athletes after training.
