Why the Time Change Impacts Your Body More Than You Expect
Even though it is only an hour, Daylight Saving Time can definitely disrupt your circadian rhythm. Your circadian rhythm helps regulate sleep, hunger hormones, digestion, and mood. When your sleep timing shifts suddenly, your body needs time to recalibrate.
For many people, this shows up as feeling more tired during the day, especially when waking up in the morning, more snacky in the afternoon, and less emotionally regulated in the evenings.
The Sleep & Hunger Hormone Connection
When sleep quality drops, hunger hormones often change.
Two common shifts:
- Ghrelin, the “hunger hormone”, can increase, which increases appetite
- Leptin, the “fullness hormone”, can decrease, which makes it harder to feel satisfied
This does not mean that anything is wrong with you. It means your body is responding to a real biological stressor.
Why Cravings Increase After the Time Change
Cravings often increase because your brain looks for quick energy when it is tired. Refined carbohydrates and sugary foods provide quick glucose and quick relief, even though the relief is short-lived.
A time change also increases the chance of blood sugar swings throughout the day. If you are reaching for coffee and something quick in the morning, or skipping meals because you are running behind, cravings can intensify by late afternoon.
Mood Changes Are Common Too
Sleep disruption can increase irritability and anxiety, especially if your stress levels already run high. Less sleep can also make normal stress feel heavier and even more stress-inducing. That emotional load can make comfort eating more likely to occur.
If you notice more emotional eating around the time change, it is not a lack of discipline. It is often your nervous system looking for relief.
What Helps the Most in the First Week
You do not need a major reset. A few consistent changes usually will help.
Helpful strategies include:
- Morning light exposure as early as possible
- Adequate protein at breakfast to reduce blood sugar swings throughout the day
- A planned mid-morning and/or afternoon snack with protein and fiber
- Less caffeine after midday, focusing on increasing water intake
- A consistent bedtime routine for at least a few nights
A Simple Day of Eating That Supports Appetite & Mood
You can keep it realistic and simple.
Example:
- Breakfast: eggs with high-fiber toast and fruit, or Greek yogurt with berries and chia, hemp, flax, or basil seeds
- Lunch: protein plus non-starchy vegetables plus a carbohydrate you enjoy
- Snack: apple and nut butter, yogurt and berries, hummus and crackers, roasted edamame, or roasted chickpeas
- Dinner: balanced meal with protein, non-starchy vegetables, and a satisfying carbohydrate
The goal is not to eat perfectly. The goal is to reduce the glucose roller coaster that often follows disrupted sleep.
