One of the best experiences is cold water diving as cold water offers an amazing underwater ecosystem with beautiful and strange sights increased in cold waters. One disadvantage however is keeping comfy and warm and it is often easier than you might think. Try these tips to make your icy scuba diving experience memorable and enjoyable while warm.
A dry suit is perfect although it is complicated to get in and you spend less energy to keep warm while diving and you stay much warmer. The risk of hypothermia is considerably less and you can stay in icy water for much longer too.
In water as cold as 5C you can get away with a 7mm wetsuit. The secret though is to prime the wetsuit before you dive into cold water, this is done by having hot water in insulated container and once you have your wetsuit on, pout hot water down the front of the suit, until it leaks from your ankles. If you do it the same way with your gloves and boots, your body does not have to use energy in warming the water layer between wetsuit and skin. Even wearing surgical gloves from latex under gloves reduces additional heat loss. Once your dive is over, use hot water again to thaw regulators, zippers, frozen fingers and face.
We all know that extra fat is a welcome insulation against cold and in icy water, however the skinny ones do well with a solid breakfast and a cup of warm beverage before a dive. Carbohydrate filled snacks after your dive will also add the calories you burned while your body fought to stay warm in the cold water.
Before and after an icy dive you need to keep warm when you can. Keep a warm jacket and keep it on until you dive and put it on immediately after getting out.
