Why Poor Sleep Makes You Crave Junk Food
Struggling with late-night snack attacks? Your sleep quality might be to blame.
Research from The American Journal of Clinical Nutrition found that sleep deprivation:
- ā Increases cravings for high-calorie foods by 30%
- ā Reduces willpower by impairing prefrontal cortex function
- ā Disrupts hunger hormones, making you feel hungrier
The good news? Optimizing your sleep can reset cravings naturally. Hereās how.
4 Sleep Hacks to Reduce Junk Food Cravings
1. The 1-Hour Digital Sunset (Dim Lights for Better Melatonin)
What to do:
- Lower lights 1 hour before bed
- Use warm, dim bulbs (under 3000K)
- Avoid screens or use blue light blockers
Why it works:
Bright light suppresses melatonin (sleep hormone) and increases ghrelin (hunger hormone). A dark environment helps regulate both.
š Study: Participants exposed to dim light before bed consumed 176 fewer calories the next day (JAMA Internal Medicine).
2. Silk Sleep Mask Trick (Improves Sleep Quality Instantly)
How it helps:
- Blocks 100% of light for deeper, uninterrupted sleep
- Reduces nighttime wake-ups
- Regulates cortisol, a stress hormone linked to cravings
Budget Tip: High-quality silk sleep masks cost under and last for years.
Ideal sleep temperature: 65Ā°F (18Ā°C)
Benefits:
- Promotes fat-burning during sleep
- Enhances REM sleep (critical for appetite regulation)
- Reduces midnight wake-ups
Hack: Take a warm bath before bed ā the post-bath cooldown triggers sleepiness.
4. Pre-Bed Protein Snack (Stops 3 AM Hunger)
Best options:
- Cottage cheese (rich in casein, a slow-digesting protein)
- Almond butter (healthy fats + magnesium)
- Chamomile tea (calms cravings + supports sleep)
Avoid: Sugary snacks that spike blood sugar before bed.
