One hour of exercise lows blood sugar level?

One hour of exercise can indeed have an impact on blood sugar levels, but the extent to which it lowers blood sugar levels can vary depending on several factors, including the type of exercise, intensity, duration, and individual characteristics.

Generally, during exercise, muscles use glucose for energy, which can lead to a decrease in blood sugar levels. However, the effect of exercise on blood sugar levels can be influenced by the individual's overall health and fitness level, insulin sensitivity, and the timing of exercise in relation to meals or insulin administration.

For people with type 1 diabetes, exercise can pose a unique challenge as it can both lower blood sugar levels and increase the need for insulin. Therefore, careful planning and monitoring of blood sugar levels are essential before, during, and after exercise to avoid hypoglycemia (low blood sugar).

For individuals with type 2 diabetes or prediabetes, exercise can be a beneficial component of managing their condition. Regular physical activity can improve insulin sensitivity, making the cells more responsive to insulin and allowing for better glucose uptake from the blood. As a result, blood sugar levels may be lowered over time with consistent exercise and a healthy lifestyle.

In general, moderate-intensity aerobic exercises such as brisk walking, swimming, or cycling for at least 30 minutes can help lower blood sugar levels. However, it's important to note that individual responses may vary, and it's always advisable to consult with a healthcare provider or a registered dietitian before starting an exercise program, especially if you have any underlying health conditions or are taking medications that affect blood sugar levels.
