As we learn more about how blood sugar affects our health, many of us are making positive changes to our diets. But diet isn’t the only factor—daily habits can also influence glucose levels. Here are eight things to keep in mind when trying to maintain stable blood sugar.
1. Poor Sleep
After a night of too little rest, you might feel groggy, but your metabolism is also affected. Research shows that even one night of insufficient sleep can reduce insulin sensitivity and raise blood sugar, even in healthy individuals. When tired, your body processes sugar more slowly.
2. Dehydration
Staying hydrated is key to good health. Not drinking enough water can lead to headaches and fatigue, and it also increases the concentration of glucose in your blood. Studies indicate that dehydration raises blood sugar both by concentrating the blood and through hormonal responses like the release of vasopressin and cortisol. Regularly skimping on water raises the risk of chronic high blood sugar.
3. Sitting Too Much
Sitting for long periods isn’t just hard on your muscles—it also disrupts metabolism, affecting blood sugar regulation, blood pressure, and fat burning. People who sit eight hours or more daily have a higher diabetes risk, even if they exercise regularly. The good news? Taking short breaks to move helps. Just two minutes of light walking every 20 minutes can reduce blood sugar and insulin spikes after meals.
4. Too Much Caffeine
While many rely on their morning coffee, too much caffeine can temporarily lower insulin sensitivity, slowing sugar processing. Pairing coffee with sugary snacks makes matters worse. You don’t have to give up coffee entirely—having it after a meal or with fiber and protein can lessen the impact.
5. Stress
Stress triggers the release of cortisol and adrenaline, which raise blood sugar to prepare the body for action. Even everyday stressors like arguments or presentations can cause a temporary spike. Taking short breaks for light exercise or deep breathing can help lower stress quickly.
6. Evening Screen Time
Many of us unwind with screens before bed, but artificial light in the evening can disrupt our circadian rhythm and increase insulin levels. This affects how the body handles sugar. Even dim light during sleep can influence blood sugar, so try avoiding screens for at least an hour before bedtime.
7. Skipping Breakfast
Though intermittent fasting is trendy, skipping breakfast may lead to a sharper blood sugar rise at lunch. After an overnight fast, the body expects morning energy. If you’re sensitive to this, try starting the day with a small, balanced meal or plan lighter meals on fasting days.
8. Nicotine
Smoking not only harms the heart…Smoking doesn’t just harm the heart and lungs—it also negatively impacts blood sugar. Nicotine can raise sugar levels and has been found to worsen insulin function in people with type 2 diabetes. Long-term studies show that heavy smokers have up to a 36 percent higher risk of developing diabetes. The good news is that cutting back quickly reduces this risk, and quitting altogether offers the greatest improvement for blood sugar and overall metabolic health.
