During prolonged hot days, people with diabetes are at high risk of blood sugar disorders due to the direct impact of environmental temperature on the body.
Accordingly, high temperatures cause the body to sweat more, easily leading to dehydration. This condition can cause blood sugar to rise higher than normal. Conversely, when blood sugar increases, the body tends to urinate more to excrete glucose, thereby continuing to cause dehydration. These two mechanisms form a vicious cycle that makes blood sugar control more difficult in the hot season.
Doctors recommend that patients pay special attention to maintaining reasonable exercise. Exercise is still necessary but should avoid sunny hours from 10 am to 4 pm. Instead, patients can choose indoor exercises such as yoga, walking on a treadmill or gentle stretching exercises. When forced to go out, it is necessary to wear a hat, sunglasses, wear cool clothes and use sunscreen to reduce the impact of heat.
In addition, water supplementation plays an important role in stabilizing blood sugar. Patients should drink enough water every day, prioritizing filtered water or low-sugar fruit juices such as lemon, apple, strawberry. Juicy fruits such as cucumbers, along with fiber-rich green vegetables such as celery, also help support blood sugar balance effectively. At the same time, it is necessary to limit alcohol and caffeine-containing drinks because they can increase dehydration.
In daily activities, patients should monitor blood sugar regularly, especially in the morning, after meals and after exercise to promptly adjust their diet or take medication. The preservation of insulin also needs to be noted, avoided in places with high temperatures and heat-retaining bags should be used when moving far to ensure drug effectiveness.
Patients should also minimize outdoor activities in hot weather to avoid the risk of dehydration and blood sugar disorders. When abnormal signs appear such as dizziness, nausea or fatigue, blood sugar should be checked immediately and treated promptly with juice or glucose according to medical instructions.
