Humans are tropical creatures & to survive outside a tropical environment, humans must use clothing & shelter to prevent body cooling.
Incidents can occur at sea because the victims:
- Can't swim & then drown in the sea
- Exposed to cold weather & water
- Not using PPE & rescue equipment (life jackets, wetsuits, life rafts & more)
Things to remember:
- Cold air & water will irritate the skin, muscles, breathing, nerves & heart (usually called cold shock)
- Breathing that is not done properly & uncontrolled will disrupt blood flow, nervous system & heart
- Disorders of the heart when at sea can lead to stroke & heart attack
- Inability to control breathing resulting in drowning
- Various disturbances in the body will interfere with swimming performance & other actions that are important for survival
- Disturbed body temperature (Hypothermia) can cause death
- Hypothermia can cause confusion, disorientation, amnesia, cardiac arrhythmias, loss of consciousness & death
Simple tips:
- If you don't need to be in the sea, try to keep your body dry & warm
- If you need to jump to the sea, enter the sea slowly
