ESPFeeling cranky, anxious, tired or just a little “off?” Sometimes the reason may be more physical than emotional. Your brain depends on glucose for energy, so changes in blood sugar can affect how you feel, think and function. That doesn't mean every bad mood is caused by blood sugar—but significant highs and lows can certainly play a rol.*
Low blood sugar can come on quickly. Along with hunger, sweating or shakiness, you may feel irritable, impatient, nervous, anxious or confused. For people with diabetes, blood sugar below 70 mg/dL is considered low and should be treated promptly.
On the other hand, foods high in added sugar and refined carbohydrates can cause blood glucose to rise quickly. For some people, the ups and downs that follow may leave them feeling less than their best. Instead of chasing another quick burst of energy, try giving your body more consistent fuel.
But your emotions can affect your blood sugar, too. When you're stressed, your body releases hormones that can cause blood sugar to rise or fall unpredictably. So, stress can affect blood sugar—and changes in blood sugar can affect how you feel.
Exercise, adequate sleep, regular meals and stress-management techniques such as meditation or yoga can help support both physical and emotional health.
