In hot climates, glucose meters may not be quite as accurate (this is the same in really cold climates!). In the heat, the blood flow to the skin is faster and nearer the surface to keep you cool. As a result, your insulin may well be absorbed quicker and your usual dose may seem to be more effective than usual, predisposing you to hypoglycaemia. However, there is some evidence that sunbathing can put your blood glucose up!

You are also more prone to hypos in cold conditions. Your body uses more energy to stay warm, increasing the risk of hypothermia. So, guard against them and wrap up well. This is also important in looking after your feet and hands, particularly if you have reduced circulation, sensation or some neuropathy. It may be more difficult to get your finger to bleed for a blood test in colder weather but you should be able to scan a sensor over the top of your clothes.

You may need to think about where to inject your insulin if you’re wearing hundreds of layers to keep warm. Insulin pens need to be kept close to the skin or at least away from the chill, so the insulin doesn’t freeze. A pump should be already close to your skin. Insulin may be slow to be absorbed and it may seem as if it’s slow to work. But this will speed up as the body warms up.
