Yes, knight armor could get extremely hot, especially during prolonged periods of physical exertion in warm weather.
Factors Contributing to Heat:
- Material: Plate armor, made of steel, is an excellent conductor of heat. Sunlight would readily heat the metal, and the wearer's body heat would be trapped inside.
- Weight: The weight of the armor, typically 50-70 pounds, hindered movement and ventilation, further exacerbating heat buildup.
- Activity: Combat or even just marching in heavy armor would generate significant body heat, trapped by the armor.
Mitigation Strategies:
- Ventilation: Some armor designs incorporated small gaps or slits for airflow, though these were often limited to reduce vulnerability.
- Padding: Underneath the armor, knights wore layers of padded clothing, which provided some insulation and absorbed sweat.
- Breaks: Knights would take breaks during battles or marches to rest and cool down, though this was not always possible.
Impact of Heat:
- Dehydration: Excessive sweating could lead to dehydration, which could impair cognitive function and physical performance.
- Heatstroke: In extreme cases, heatstroke could occur, potentially leading to death.
- Fatigue: The combination of heat and exertion could lead to fatigue, reducing a knight's effectiveness in combat.
While knight armor provided crucial protection, it came at the cost of significant discomfort and potential health risks due to heat.
