Effect of Ambient Temperature on Blood Glucose and Insulin Absorption in Adults With Type 1 Diabetes
Effect of Ambient Temperature on Insulin Absorption and Change in Blood Glucose Levels in Individuals With Type 1 Diabetes
Source: ClinicalTrials.gov · Last updated 24 Mar 2026
Brief summary (registry, in English)
The goal of this clinical trial is to learn how different temperatures affect blood sugar levels in adults with type 1 diabetes. Climate change is causing more extreme hot and cold weather, and people with type 1 diabetes may be at higher risk during these temperature changes. The main questions it aims to answer are: * Do different temperatures (cold, normal, or hot) change blood sugar levels in people with type 1 diabetes? * How does temperature affect insulin absorption in the body? Researchers will compare three different temperature conditions to see how each affects blood sugar levels and insulin in the body. Participants will: * Complete a screening visit with body measurements and questionnaires * Attend 3 separate study visits, each in a different temperature setting: * Cold room (10°C/50°F) * Normal room temperature (23°C/73°F) * Hot and humid room (36°C/97°F with 65% humidity) * Sit for 2 hours in each temperature condition while researchers monitor their blood sugar, heart rate, and body temperature * Wear a continuous glucose monitor for 48-72 hours before each visit * Keep a diary of food, sleep, and activity for 24 hours before and after each visit Each temperature visit is separated by at least 3 days. The study helps researchers understand if people with type 1 diabetes need special guidance for managing their blood sugar during extreme weather.
