3. Cut Back On Sugar
While sugar is undoubtedly delicious, it is a short-term energy source and leads to rapid changes in levels of blood sugar. If you eat a sugar bomb treat before bed, the resulting sugar rash can interrupt your sleep and lead to bouts of insomnia, especially if those sugar bomb nighttime snacks are a regular occurrence.
Depending on your overall diet and if you have any underlying health issues like diabetes, try either not snacking before bedtime at all or eat a longer-lasting snack like an apple, with its complex carbs and pectin, or nuts with their slow release of protein-based energy.
