Sleep, stress and hunger
Short sleep makes hunger hormones work against you. A few habits for better nights.
3 min read · 03 Nov 2026
If you have ever felt hungrier after a bad night, you are not imagining it. In studies, short sleep raised ghrelin (a hunger signal) and lowered leptin (a fullness signal), and people reported more appetite, especially for sweet and starchy foods.
Habits for better sleep
- Keep a regular bed and wake time, even on weekends
- Finish your last meal 2 to 3 hours before bed — an early eating window helps
- Limit coffee and tea after mid-afternoon
- Dim screens and lights in the last hour
- A short evening walk helps many people
Stress
Stress can push us towards comfort eating. Slow breathing, a walk, prayer or a chat with someone you trust can break the cycle. Log your energy, hunger and mood each day to spot patterns.
