It is common sense that you should not go cold in any way, since it presents a great danger to the human body, either thanks to serious degrees of hypothermia to the most severe if one is not well protected. It’s not the only problem. Vasoconstriction caused by cold throughout the body increases, and greatly, the risk of decompression accident. Manual dive decompression tables do not take this data into account, although luckily all current dive computers do contemplate it, so having a dive computer is highly recommended when doing this sport.
You should always dive with the dive computer, so it is very important to keep it in optimal conditions, even if it is one of the most expensive diving tools, at the time of safety its price is minimal. Talk to an expert or dive coach to know how to handle this important tool.
We must not forget that you can dive differently in winter. Shorter dives, at a lower depth, avoid decompression, actively swimming to generate heat.
This is where the scuba wetsuit comes in. Each diving suit offers a variety of fabrics and clothing, the delicate thing about this is that many manufacturers usually sell a series of diving suits that are not always suitable for cold water temperatures. For this reason, they are usually only used in summer seasons or in warm temperatures.
They are suits made with a porous and flexible plastic material called neoprene. These suits do not prevent water from coming into contact with the diver, which prevents the diver from having problems with cold water. For it to be, it must be a suit that fits the body properly.
The best wet suit to combat the cold is 7 millimeters thick, even if you have a versatility between 3 millimeters to 7 millimeters, 7 is the most suitable. When buying a scuba wetsuit, a two-piece suit is recommended. This way you will get double protection against cold water.
Let’s talk about the hood that should be taken when entering cooler waters. Recommended for winter use is a hood about 5 millimeters thick. Gloves and ankle boots are essential to combat cold water, the extremities are the most delicate of the human body in relation to the cold, so you should take care of yourself with greater zeal.
It must be taken into account that dry or semi-dry suits even when they can be used for cold waters, 7 mm wet suits are the most suitable, so that the cold of the water can cause damage or problems to the diver.
If you are a beginner who wants to practice this sport, do not be fooled and do not believe in those people who offer you an “economical” suit, diving suits are expensive, good diving suits are made with a special fabric. Remember that you will not always be in warm water, and that the cold is the number one enemy of this sport.
