As explained in Diabetes Forecast magazine, apart from administrating insulin, physical activity is the quickest way to lower blood sugar levels. The American Diabetic Association says the effect exercise has on blood glucose levels depends upon a number of factors, but it can lower them for up to twenty-four hours after physical exercise has taken place.
The British National Health Service states that high blood sugar levels (hyperglycemia) occur when the body can't remove glucose from the blood to turn it into energy. This results in symptoms such as increased thirst, a need to urinate frequently and tiredness.
Exercise can help lower blood sugar levels because, as WebMD says, during exercise, muscles contract, and this allows cells to take up much more glucose. In doing so, this takes glucose away from the bloodstream and, as such, lowers blood glucose levels.
The American Diabetes Association reports that stress can also be a factor in having higher blood sugar levels, so relaxing or carrying out controlled breathing exercises can also help bring down your sugar levels. Regular exercise along with a balanced diet can continue to keep your blood glucose at the correct level. People with consistently high sugar levels should consult a doctor.
