About

MyTrials

Features
Read full description

An app to help researchers capture biospecimens (e.g., temperature, blood pressure) remotely from research study participants. Are you enrolled in a remote research study? Do you have to submit biospecimen readings and complete questionnaires as part of your participation? The MyTrials app allows research participants in remote studies to easily complete and submit biospecimen readings and questionnaires all in one place. Get reminders about upcoming biospecimen submissions and questionnaires so you never miss a follow-up. DISCLAIMER: MyTrials may connect to bluetooth devices that take biometric readings which are informational only and not intended to be used for making medical decisions. Seek a doctor’s advice as a result of concern from any biometric readings before making any medical decisions.

Join Groundbreaking Climate-Mental Health Research The HEAT-MIND Lab app connects you to cutting-edge research exploring how rising temperatures affect mental health. By participating, you'll contribute to science that could protect millions as our planet warms. Why This Research Matters Climate change isn't just an environmental issue – it's a mental health crisis. Young adults are particularly vulnerable, experiencing a 3% increase in suicide rates for every 2Β°F temperature rise during the summer – that's an effect as large as what we see after major environmental disasters. That's why our research focuses on your age group. With global temperatures expected to rise by nearly 8Β°F by 2100, we urgently need solutions. The Challenge We're Addressing While we know heat affects mental health, we don't fully understand how. Does it disrupt sleep? Make it harder to think clearly? Interfere with exercise and socializing? Understanding these pathways is crucial for developing effective interventions. How the App Works As a participant, you'll wear small sensors that continuously monitor the temperature and humidity around you, along with sleep and activity trackers. Through the app, you'll complete regular surveys about your mood, depression symptoms, and cognitive performance over one month. For the first time, we'll see how real-world temperature exposures relate to mental health symptoms, sleep quality, thinking ability, and physical activity patterns in everyday settings. We’ll see if daytime versus nighttime heat exposure affects mood differently. We’ll also see if factors like gender, race, education, income, geography, or medications make people more vulnerable or protected. Real-World Impact Your participation will help us identify targets for practical, affordable interventions to maintain mental wellness during hot weather. We're committed to developing clinical guidelines that reduce human suffering as temperatures rise. Our Broader Mission HEAT-MIND Lab (Healthy Environments and Temperatures – Mechanisms in Neuropsychiatric Disorders) integrates lived experiences of people with mental health conditions into every aspect of our research. We're training the next generation of researchers and sharing our methods so scientists worldwide can advance this critical field. We believe in meeting people where they are, sharing findings through social media, news outlets, and community channels – not just academic journals. We're also developing training for mental health professionals to understand climate impacts on their patients. Be Part of the Solution This research prepares us for the mental health challenges of climate change. By participating, you're not just contributing data – you're helping build a future where we can protect psychological well-being in a warming world.
