Why You Feel Hungrier in Cold Weather

When the temperature drops, have you ever noticed your appetite seems to rise? You’re not alone. Feeling hungrier in the winter is a common experience, and it’s not just about holiday indulgence or cozy comfort food. Science suggests there are both biological and emotional reasons why colder weather increases hunger and understanding them can help you navigate seasonal cravings with greater awareness and balance.

1. Your Body’s Ancient Survival Instincts

Long before modern grocery stores and food delivery apps, humans had to hunt, gather, and farm their food often under harsh weather conditions. Cold weather meant a greater need for calories to stay warm and fueled, which created a biological drive to eat more during the winter months.

Historical shifts in food access help explain this:

• Pre-1800s: Most people burned high levels of energy to obtain food, facing seasonal scarcity.

• 1800s to early 1900s: Agriculture and industrialization improved food availability, but shortages were still common.

• Mid-1900s onward: With less physical labor and more food access, overeating and weight-related health issues became more prominent.

Even though we no longer rely on food for basic survival in the same way, the instinct to “stock up” during colder months remains deeply ingrained.

2. Emotional Eating and Winter Traditions

Winter is packed with occasions that center around food holidays, family gatherings, football games, and seasonal treats. These events often include calorie-dense meals and indulgent desserts that are high in sugar and fat, which can spike your blood sugar and leave you feeling hungrier shortly after.

But it’s not just tradition; food also becomes a form of emotional comfort during colder, darker months especially for those dealing with grief, loneliness, or post-breakup heartache. Emotional eating is a natural response to seeking warmth and pleasure, especially when it’s cold outside and moods may dip.

3. Seasonal Affective Disorder (SAD)

About 5% of Americans experience Seasonal Affective Disorder (SAD) each year, with women making up nearly 80% of cases. This form of depression typically occurs in the fall and winter, triggered by reduced sunlight and shorter days.

A common symptom? Increased hunger and cravings, especially for carbs and sweets. This can lead to weight gain and make the winter months feel even more emotionally challenging. Treatments like Cognitive Behavioral Therapy (CBT) and light therapy can help manage both the emotional and physical symptoms of SAD, including excessive hunger.

4. Hormonal Shifts and Cravings

Serotonin and melatonin two hormones closely tied to mood, sleep, and appetite are affected by seasonal light exposure. In winter:

• Less sunlight leads to lower serotonin, a neurotransmitter that stabilizes mood and appetite.

• Increased melatonin (due to longer nights) can trigger fatigue and, for some, greater food cravings especially for carbs and comfort foods.

This hormonal imbalance contributes to that sleepy, snacky feeling many experience during colder months.

5. Lifestyle Changes and Boredom Eating

As temperatures fall and daylight hours shrink, many people naturally spend more time indoors. This can reduce physical activity and increase feelings of boredom or restlessness both of which are associated with mindless snacking or emotional eating.

Research suggests that boredom alone can increase hunger signals, even when your body doesn’t truly need more food. Structuring your days, staying active, and finding ways to stay mentally engaged can help reduce boredom-driven eating.

6. Increased Caloric Needs in Cold Weather

Your body works harder to regulate its internal temperature in cold environments, and that burns more energy even when you’re at rest. While the average person may only need about 5–15% more calories in chilly (but not extreme) weather, those in arctic or high-exertion cold conditions may require 25–50% more.

This extra energy demand prompts your brain to send hunger cues to ensure you’re getting enough fuel, especially if you’re frequently outdoors or exposed to the cold for extended periods.

How to Stay Balanced During the Cold Months

Feeling hungrier in winter isn’t something to feel guilty about it’s a natural response to environmental and emotional shifts. But there are ways to support your body and mind through the season:

• Eat balanced meals with fiber, protein, and healthy fats to stay fuller longer

• Keep hydrated thirst can often be mistaken for hunger

• Get regular sunlight exposure or use a light therapy box to help regulate hormones

• Stay physically active with winter-friendly workouts or indoor routines

• Acknowledge emotional eating patterns without judgment and seek support when needed

The Takeaway

Whether it’s hormones, history, or holiday habits, cold weather can turn up your hunger. But understanding what’s behind the cravings gives you the power to respond with intention. After all, taking care of your body doesn’t mean ignoring your appetite it means learning how to listen to it wisely.
