Morning vs. Evening Walks: Which Is Better for Blood Sugar?
Key Takeaways
- A 10-minute walk after eating can help slow the rise in blood sugar.
- A 30-minute walk before breakfast may lower high morning blood sugar in people with type 2 diabetes.
- While an evening walk after dinner can lower blood sugar spikes, late exercise may affect sleep or cause low blood sugar overnight.
Both morning and evening walks can help manage blood sugar, but the best time to walk may depend on when your blood sugar tends to rise. Morning walks may help with elevated blood sugar after waking, while evening walks can reduce after-dinner spikes. Research also suggests that walking after meals, even for just 10 minutes, may be particularly beneficial for blood sugar control.
Morning Walks May Help With High Blood Sugar After Waking
Blood glucose levels may be higher in the morning, despite following hours of fasting. Exercise, such as walking, in the morning may help with high blood sugar in the morning, particularly from the dawn phenomenon.
The dawn phenomenon occurs when hormones signal the liver to release more glucose in preparation for waking. For people with diabetes, the body may not produce enough insulin to counter this rise.
According to research, 30 minutes of moderate aerobic exercise before breakfast has been shown to reduce the rise of blood sugar at dawn in people with type 2 diabetes. Morning exercise is also associated with better overall blood sugar control throughout the day.
For some, morning walks fit into a daily schedule better than in the evening, when there may be more activities to try to fit in. Morning exercise has also been associated with greater adherence to regular physical activity.
Evening Walks May Help Reduce After-Dinner Spikes
Taking an evening walk after dinner can help reduce postprandial (post-meal) blood sugar spikes. Recent research has suggested that walking 30 minutes after your meal for just 10 minutes can be effective in managing the post-meal blood sugar rise.1
As many people eat their largest and/or most carb-heavy meals at dinner, an evening walk may be good timing if you are choosing one meal per day to exercise after.
Some precautions for walking in the evening include:
- Exercising too close to bedtime could interfere with sleep.
- For people with type 1 diabetes, and those who rely on insulin, late-day exercise could lead to nocturnal hypoglycemia (low blood sugar overnight).
If you are experiencing sleep disruption or lows overnight, morning walks may be a better option.
Considerations When Choosing What Time to Walk
Morning walks may be beneficial if you have high blood sugar upon waking, while evening walks can help reduce post-dinner glucose spikes. The choice may depend on your schedule, medications, and blood sugar patterns.
Which is better appears to come down to what works best for the individual. When choosing when to exercise, there need to be considerations such as:6
- When is medication taken and how is it affected by exercise?
- When are you most likely to stick to a regular, long-term exercise routine?
- When can you make time for exercise?
- When do you tend to have blood sugar highs and lows?
- What are your natural sleep and wake habits?
Walking After Meals May Matter More Than Time of Day
Morning and evening are not the only times that walking and other exercise are beneficial for blood sugar management. No matter what time of day, walking after any meal can be beneficial.
It is normal for blood sugar to rise after a meal, both for people who do and do not have diabetes. However, taking a walk, even for just 10 minutes, after eating can help slow the rise.
If walking after every meal is not realistic for you, try to aim for walking after as many as you can. There is some evidence that regular exercise may help improve long-term blood sugar control in people with type 2 diabetes.
However, studies have produced mixed findings on the ideal timing, duration, and intensity of post-meal exercise.
Find the walking schedule that works best for you, whether it’s planning to walk at least 30 minutes after each meal or splitting up that time into shorter sessions.
