Blood sugar, or blood glucose, is the main sugar found in the blood. It is our body’s primary source of energy and comes from the food we eat. When your blood glucose goes up, it signals your pancreas to release insulin. However, when things aren’t functioning properly, you can develop high blood sugar, which means there is too much sugar in your bloodstream. You may have high blood sugar due to:
- Your body isn’t using insulin correctly
- Your pancreas doesn’t make enough insulin
Elevated blood sugar levels can cause blood vessel damage, which can lead to serious complications, such as:
- Heart attack
- Stroke
- Diabetes-related retinopathy, which can cause blindness
- Diabetes-related nephropathy, which can lead to kidney failure
- Nerve damage
Our blood sugar naturally rises when we eat and is highest about 30 to 90 minutes after eating. However, frequent or especially high spikes in blood sugar levels can increase the risk of or worsen diabetes.
Fortunately, there are several ways to lower blood sugar levels into a healthy range, such as eating healthy, getting regular exercise, and managing stress. Another way to manage blood sugar levels is to take a short walk after eating.
Research shows that a short walk after a meal can:
- Prevent your blood sugar from spiking as high as it would if you ate and remained seated
- Keep your insulin levels stable
Walking for ten minutes, or as little as two to five minutes, can lower your blood sugar.
When walking after a meal, it is important to stay safe. Some safety tips to keep in mind when walking include:
- Go slow and gradually increase your physical activity
- Avoid environmental triggers, such as high heat and humidity, environmental allergens, cold air, and safety hazards
- Fall prevention for those who are 65 years of age and older
