Eat plenty of carbohydrate-rich meals or snacks
One of the evening habits that can disrupt blood sugar is eating large meals or snacking with a lot of starch, especially a few hours before bed. In the evening, the body processes glucose less than during the day, so eating a lot of carbohydrates (especially sweets and soft drinks after 5pm) will easily cause a sudden, uncontrollable increase in blood sugar.
Drinking alcohol
Even a single cocktail for dinner can affect your blood sugar throughout the night. Alcohol can initially lower blood sugar, but then cause it to increase again, while disrupting sleep. The reason is that the liver has to focus on metabolizing alcohol, so it does not release enough glucose to keep blood sugar stable. This is even more dangerous if you are taking hypoglycemic drugs or drinking sugary pre-mixed foods.
Not drinking enough water
Lack of water in the evening causes blood glucose to be more concentrated, increasing blood sugar and reducing insulin sensitivity. Drinking enough water will help keep blood sugar stable. However, you should not drink too much right before bed to avoid having to wake up to go to the toilet many times, affecting sleep.
