Cold weather
In colder conditions, insulin may be absorbed more slowly at first, but once you warm up, it can be absorbed rapidly, which increases the risk of hypoglycemia (low blood sugar).
Additionally, your body expends more energy to maintain warmth, such as when shivering, which can also trigger low blood sugar. To help manage this, dress in layers so you can stay warm and remove clothing as you heat up.
Hypoglycemia in cold weather can be particularly dangerous since it affects your body's ability to stay warm, raising the risk of hypothermia.
