Does Exercise Lower Blood Sugar?


Exercise is not only beneficial for weight loss and overall health, but it can also play a crucial role in managing blood sugar levels. Regular physical activity is known to lower blood sugar levels and improve insulin sensitivity in individuals with diabetes or prediabetes.

How Does Exercise Affect Blood Sugar?

When you exercise, your muscles require energy, which is primarily supplied by glucose. To meet this demand, your body increases insulin production, allowing glucose to enter the cells and fuel your muscles. As a result, blood sugar levels decrease during and after exercise.

The Immediate Effects of Exercise on Blood Sugar

During exercise, your muscles take up glucose from the bloodstream without the need for insulin. This means that even if you have insulin resistance or insufficient insulin, exercise can still help lower your blood sugar levels. The immediate effects of exercise can last for several hours, depending on the intensity and duration of the activity.

The Long-Term Benefits of Regular Exercise

In addition to the immediate effects, regular exercise can have long-term benefits for blood sugar control. Physical activity helps increase insulin sensitivity, allowing your body to use insulin more effectively. This can lead to improved blood sugar control and reduced risk of developing type 2 diabetes.

Types of Exercise That Lower Blood Sugar

Various types of exercise can help lower blood sugar levels. Aerobic exercises, such as walking, jogging, swimming, and cycling, are particularly effective in improving blood sugar control. Strength training exercises, such as weightlifting, can also have a positive impact on blood sugar levels.

Best Time to Exercise for Blood Sugar Control

The timing of exercise can also influence its effects on blood sugar levels. Some studies suggest that exercising before meals may help lower post-meal blood sugar spikes. However, the best time to exercise for blood sugar control may vary depending on individual preferences and lifestyle factors. It is important to find a routine that works for you and stick to it.

Considerations for People with Diabetes

If you have diabetes, it is essential to monitor your blood sugar levels before, during, and after exercise. This will help you understand how different types and durations of exercise affect your blood sugar levels. It is also important to consult with your healthcare provider before starting a new exercise regimen and to adjust your diabetes management plan accordingly.


Regular exercise can be a powerful tool in managing blood sugar levels. It not only helps lower blood sugar immediately but also improves insulin sensitivity and long-term blood sugar control. By incorporating physical activity into your daily routine, you can take control of your blood sugar and improve your overall health.
