Cold Weather Boosts Hunger and Heightens Respiratory Risks, Experts Advise Caution

Nutritionist Taynara Abreu explains that falling temperatures increase the body's energy expenditure, often prompting a stronger desire for calorie‑dense foods such as chocolates, pasta and other comfort meals. She notes that the rise in appetite is partly physiological, as the body works to maintain core temperature, and partly emotional, with people seeking warmth and well‑being from food. Hydration remains important, as reduced thirst in winter can be mistaken for hunger.

Otolaryngologists Roberta Pilla and Maura Neves warn that indoor heating units commonly used in the cold season dry the air, impairing the mucosal barrier that normally filters and humidifies inhaled air. This dryness can trigger nasal congestion, nosebleeds, dry cough, throat irritation and aggravate conditions like rhinitis, sinusitis and asthma, especially in children and the elderly. They recommend using humidifiers or placing water trays near heaters, keeping indoor humidity between 40‑60 %, ventilating rooms regularly, limiting heater use at night, and practicing nasal irrigation and adequate fluid intake.

Combined, these insights suggest that while the cold season can increase caloric needs, it also poses respiratory challenges. Balanced meals rich in protein, fiber and healthy fats, along with consistent hydration and mindful heater operation, can help people stay healthy and comfortable during winter.
