As an expert in the field of respiratory physiology and exercise science, I can provide a detailed explanation for why it can be difficult to breathe when running in the cold. The sensation of shortness of breath during cold weather exercise is multifactorial, involving both physiological and environmental factors.
Step 1: English Answer
Respiratory Tract and Airway Protection
The primary reason for the difficulty in breathing during cold weather exercise is the body's attempt to protect the respiratory tract. The nasal cavity is designed to filter, warm, and humidify the air we breathe. When the air is cold, the nasal passages constrict to reduce heat loss and maintain body temperature. However, this constriction can also make it harder to draw in air, leading to the sensation of shortness of breath.
Airway Irritation and Inflammation
Cold air can cause irritation and inflammation in the airways. The air we breathe is normally warmed and humidified as it passes through the nasal cavity. When we breathe in cold air, especially through the mouth, it can cause the airways to dry out and become irritated, leading to coughing and difficulty breathing.
Increased Oxygen Demand
During exercise, the body's demand for oxygen increases significantly. The muscles require more oxygen to produce the energy needed for physical activity. Cold air, being denser, contains more oxygen molecules than warm air. However, the body's ability to extract this oxygen is reduced due to the rapid inhalation and exhalation, which doesn't allow for optimal gas exchange in the lungs.
Breathing Technique
The method of breathing can also impact the ease of respiration. Breathing through the nose is more efficient because it filters and warms the air. However, the need for increased airflow during exercise can lead to mouth breathing, which allows unfiltered, cold air to enter the lungs directly, potentially causing discomfort and making it harder to breathe.
Bronchoconstriction
For some individuals, the cold air can trigger bronchoconstriction, a narrowing of the airways. This is more common in people with asthma or other respiratory conditions but can also occur in healthy individuals. Bronchoconstriction reduces the airway's diameter, making it more difficult for air to pass through and leading to shortness of breath.
**Physical Conditioning and Acclimatization**
A person's level of physical conditioning and acclimatization to the cold can also play a role. Those who are not used to exercising in cold weather may find it more challenging to breathe. Over time, the body can adapt to the cold, and breathing may become easier as the body learns to warm and humidify the air more effectively.

If you don't have asthma, it's best to breathe in through the nose so that it can be filtered and warmed. However, between a runny nose and the need for more air, many people begin mouth breathing, which means freezing cold air will be hitting your lungs, says Cohen.Jan 14, 2017
