## What are the Effects of Temperatures When Scuba Diving?

When scuba diving, it is important to be aware of the effects of temperature on your body. Water conducts heat 25 times faster than air, so even a small change in water temperature can have a significant impact on your body.

### Hypothermia

Hypothermia occurs when your body loses heat faster than it can produce it. This can happen in water temperatures as warm as 60 degrees Fahrenheit (16 degrees Celsius). Symptoms of hypothermia include:

Shivering
Cold skin
Numbness
Confusion
Loss of consciousness

If you experience any of these symptoms, get out of the water immediately and seek medical attention.

### Hyperthermia

Hyperthermia occurs when your body temperature rises to dangerous levels. This can happen in water temperatures as high as 86 degrees Fahrenheit (30 degrees Celsius). Symptoms of hyperthermia include:

Headache
Dizziness
Nausea
Vomiting
Seizures
Loss of consciousness

If you experience any of these symptoms, get out of the water immediately and cool down. You can do this by:

Drinking plenty of fluids
Taking a cold shower
Applying cold packs to your body

### Other Effects of Temperature

In addition to hypothermia and hyperthermia, there are a number of other ways that temperature can affect your body when scuba diving. These include:

Impaired mental function. Cold water can impair your mental function, making it difficult to think clearly and make decisions.
Reduced muscle strength. Cold water can reduce your muscle strength, making it difficult to swim or use your equipment.
Increased risk of decompression sickness. Cold water can increase your risk of decompression sickness, a serious condition that can occur when you ascend from a dive too quickly.
