Hot weather can affect blood sugar levels, making it harder for people with diabetes to manage their condition. High temperatures lead to increased sweating, dehydration, and elevated blood sugar. High blood sugar, in turn, causes frequent urination, accelerating dehydration and creating a cycle detrimental to blood sugar control. Dehydration also reduces blood flow to the skin, potentially affecting the body's ability to absorb insulin.

Appropriate exercise is beneficial for individuals with diabetes. However, on hot days, avoid outdoor workouts from 10h to 16h, when temperatures are highest. Instead, individuals can choose light indoor activities or cool, well-ventilated areas such as yoga, walking or running on a treadmill, or suitable stretching exercises. If going outdoors, wear sunglasses, a wide-brimmed hat, light, breathable clothing, and apply sunscreen to limit UV radiation's impact on the skin.

People with diabetes need to drink more water to prevent dehydration. Prioritize plain water or pure fruit juices with a low glycemic index, such as lemon, passion fruit, strawberry, and apple. Consuming hydrating fruits not only provides fluids but also boosts vitamins, antioxidants, and fiber, helping to stabilize blood sugar in summer. Avoid caffeine and alcohol, as both can worsen dehydration. Water-rich and high-fiber vegetables like celery, cucumber, and broccoli slow digestion and the rate at which sugar enters the bloodstream. These vegetables also provide vitamin C, enhancing immunity, making them ideal choices for diabetic meals during hot weather.

Regular blood sugar monitoring is a safe way for people with diabetes to manage their condition effectively on hot days. Individuals should have a personal glucose meter to check levels in the morning, after meals, or after exercise, allowing for timely adjustments to diet, exercise, and medication. Insulin should not be left in a hot car or direct sunlight, as high temperatures can reduce its effectiveness. When traveling, store insulin in a cooler bag or box, avoiding direct contact with ice or high heat sources. Wrapping insulin in a soft cloth can help prevent sudden temperature changes.

Limiting outdoor activities is crucial. Waiting in line for events on hot days or playing games in parks can lead to dehydration and stress, negatively impacting blood sugar levels. Therefore, during summer, people with diabetes should prioritize relaxing and engaging in indoor activities, such as visiting shopping centers, to maintain overall health. If you experience fatigue, nausea, vomiting, dizziness, or excessive sweating, check your blood sugar immediately. Additionally, carry glucose tablets, juice, or candy to promptly address low blood sugar.
