Doctor Olga Ulanikina warned that sudden immersion in cold water during hot weather can cause vascular spasms, increased blood pressure, heart strain, breathing difficulties, and muscle cramps, especially for people with pre-existing health conditions.
Consensus
- Sudden immersion in cold water during hot weather can trigger vascular spasms and increase blood pressure.
- The sudden contact with cold water can cause reflexive breath-holding, increasing the risk of water inhalation or vocal cord spasm.
- Prolonged exposure to cold water can lead to hypothermia, disrupted heart rhythm, and respiratory depression.
- Muscle cramps may occur, potentially impairing the ability to swim.
- Gradual acclimatization by first wetting hands, feet, neck, and chest is recommended to reduce risk.
- People with heart or vascular diseases, diabetes, asthma, or a tendency to cramps should exercise special caution.
