## What to Do if You’re Scuba Diving in Cold Water

Scuba diving in cold water can be an exhilarating experience, but it’s important to be prepared for the challenges that come with it. Hypothermia, dehydration, and equipment failure are all potential hazards that you need to be aware of and know how to deal with.

### 1. Dress Appropriately

The most important thing you can do to stay warm while scuba diving in cold water is to dress appropriately. This means wearing a thick wetsuit or drysuit, along with a hood, gloves, and boots. The type of suit you need will depend on the water temperature and the length of your dive.

* **Wetsuits:** Wetsuits are made of neoprene, a synthetic rubber that traps water between your skin and the suit. This water warms up and helps to keep you warm. Wetsuits are available in a variety of thicknesses, so you can choose the one that’s right for the water temperature you’ll be diving in.
* **Drysuits:** Drysuits are waterproof suits that keep you completely dry. They’re made of a variety of materials, including nylon, neoprene, and rubber. Drysuits are more expensive than wetsuits, but they’re also more effective at keeping you warm.

In addition to a wetsuit or drysuit, you’ll also need to wear a hood, gloves, and boots. These items will help to keep your head, hands, and feet warm.

### 2. Stay Hydrated

It’s important to stay hydrated when you’re scuba diving in cold water. Dehydration can lead to fatigue, dizziness, and even fainting. Drink plenty of water before, during, and after your dive.

### 3. Be Aware of the Signs of Hypothermia

Hypothermia is a serious condition that can occur when your body temperature drops too low. The symptoms of hypothermia include shivering, pale skin, confusion, and loss of consciousness.

If you think someone is experiencing hypothermia, it’s important to take action immediately. Get them out of the water and into a warm place. Remove their wet clothes and wrap them in a blanket. Give them warm drinks and food.

### 4. Know How to Use Your Equipment

It’s important to know how to use your scuba equipment properly before you dive in cold water. This includes being able to operate your regulator, buoyancy compensator device (BCD), and dive computer.

If you have any questions about how to use your equipment, be sure to ask your dive instructor.

### 5. Dive with a Buddy

Never dive in cold water alone. Always dive with a buddy so that you can help each other in case of an emergency.
