Many people feel that when temperatures change with the seasons, or when traveling to a hotter climate, BG fluctuations are more common. Is there validity in what we feel is happening?
This study looked at the effect of both temperature and humidity on insulin action in adults with type 1 diabetes.
This study, in adults with type 1 diabetes mellitus, evaluated how a single dose of short-acting insulin held up “under three environmental conditions: i) temperature: 59°F and humidity: 10%, ii) temperature: 86°F and humidity: 10%, and iii) temperature: 86°F and humidity: 60%, controlled in an environmental chamber.”
Evaluation of results showed that high ambient temperature caused a greater “insulin peak effect compared to low ambient temperature, with the contribution of high relative humidity only apparent at high ambient temperature.”
The takeaway for those with type 1 diabetes would be to consider the potential for more hypoglycemic events when spending time in higher temperatures with or without regard to high humidity.
