Cold-wet injuries
- Heat Loss Mechanisms: In cold environments, your body loses heat primarily through radiation and sweat evaporation. However, when skin and clothes are wet, heat conduction away from the body increases, causing faster heat loss.
- Water vs Air: You lose heat more quickly in water than in air of the same temperature due to the increased contribution of convective heat loss, especially when there's water movement over the body.
- Water Temperature Tolerance: Individuals have different tolerances for water temperature; body heat loss from conduction is greatest during immersion in cold water. Water temperature and exposure duration are key predictors of cold-wet injuries.
Too cold to exercise?
- Breathing Cold Air: Exercising in the cold means breathing cold and dry air, which must be warmed and humidified before entering the lungs. This can trigger asthma attacks in asthmatic individuals and those with exercise-induced asthma.
- Exercise-Induced Asthma: A study by Stenstrud et al. (2007) found that individuals with exercise-induced asthma had a lower maximum oxygen uptake and slower running speeds in a cold air environment (–18°C) compared to a 20°C environment.
- Hydration in Cold: High ventilation rates during exercise in cold air temperatures can result in significant heat loss and potentially dehydration. Therefore, ensuring adequate hydration is important during exercise in the cold.
