Thermal insulation is a key element of comfortable diving. If you're not cold and feel comfortable in the water, you not only save air but also increase your safety in terms of nitrogen saturation, fatigue, and concentration.

The moment you enter the water, you immerse your body in water that is colder than your body temperature (except in exceptional situations). Even at a moderate temperature, after long exposure, the body cools down and can even lead to hypothermia.

Have you ever been on a dive where you were so cold that you were shivering? Shivering is a symptom of hypothermia. Other symptoms that may occur or be a sign of hypothermia include clumsiness, disorientation, poor decision-making, and lack of energy. For the tough, cold water is water that will be a few degrees Celsius. However, for most, it will be higher temperatures; some will even say that cold water is 22-24 degrees Celsius. Regardless of what benchmark we adopt, if you're freezing during a dive, it's terrible. When you start to get cold, you think about getting warm, and maybe you even wonder when the dive will finally end. When it comes to thermal insulation, there are two options available, dry or wet. Below are a few arguments in favor of a drysuit.

When you dive in a drysuit, you are warmer than in a wetsuit because you are dry from the beginning. Additionally, you can choose the thickness of your undergarment and regulate thermal insulation depending on the water temperature and your own preferences. For those who have never dived in a drysuit, we explain that diving in cold water in a drysuit is like going outside on a cold day. You are in a cold environment, you feel that it's cold, but you stay warm and you are DRY.

Besides the obvious issues, there are other conditions related to diving in a drysuit compared to a wet one. As the depth increases during a dive, Boyle's law (pressure) affects us. At a depth of 10 meters, a wetsuit will compress by 50%. At a depth of 30 meters, your wetsuit is subjected to a pressure equal to 4 atmospheres, which means compression to about 25% of the original thickness of the suit. The compression of a wetsuit can affect buoyancy and thermal comfort while at the bottom. In many cases, the coldest water is encountered at the bottom.
When diving deeper in a drysuit, the suit compresses, but its real thickness does not change. To maintain comfort, you add air to the drysuit. This air space allows you to stay warm and maintain buoyancy throughout the dive. The most interesting part is that if it's colder at the bottom, you stay warm, you are dry, and you feel comfortable.​

3. NITROGEN SATURATION
Even during no-decompression dives, the body becomes saturated with nitrogen during the dive. For most divers, a 3-minute safety stop will be sufficient to remove nitrogen from the body and safely surface. Studies by various scientists dealing with decompression have shown that decompression in warm water is more conducive to releasing nitrogen than in cold water. When diving in a drysuit, you maintain thermal comfort throughout the dive and stay warm during the crucial safety stop (or decompression stop), when you are relaxed and mostly still in the water.
