How to avoid excessive body temperature loss during diving
Learning to dive allows us to get closer to the world of the sea and experience the colorful world of the underwater world. However, diving also presents many dangers. Now we introduce to everyone how to avoid excessive temperature loss in diving.

Wear a fitted waterproof jacket
Anti-cold clothing should not be so tight that you cannot breathe easily, but fits and is comfortable. As long as there are some loose areas, water will accumulate in the area, so that the body temperature will be absorbed. When you are in exercise, you will squeeze the water from the place into other parts of the anti-cold coat and contact the sea to take your body to a tropical zone. At the same time, it will bring cold water to absorb your body heat.

Wear headgear
Because there are many arteries flowing under the scalp, there will be a lot of blood and body heat passing through it. Most users of wet-type winter jackets will have their headgear partially enlarged so that they can be tightly integrated with the winter coat. If the headgear feels oppressive, you can cut the scissors with your face open. Users of dry-type winter clothes, because of the different headgear design of this type of winter clothes, do not have much pressure on the neck and can easily turn the head.

If you feel cold, dive into the shallows
Not only are the water temperatures in the shallow areas warm, your winter jackets will not be thinned by squeezing. Under water more than 18 meters, the average thickness of winter clothes will be squeezed into less than half of the original. This will also greatly reduce the degree of warmth.

When you tremble, it's time to go ashore
At this time, your mental capacity can no longer bear too much, it may make you make bad decisions. There is no fun at all.

Pay attention to insulation when resting on the water
When you take off your jacket, dry it with a towel. Or wear a dive trench coat to avoid the cold when the wind blows. In any case, when you take off your winter coat, first dry your skin and hair and put on warm clothing.

Buy your own jacket
If you are mostly engaged in diving at temperatures below 27 degrees Celsius, consider buying your own wet or even dry winter jacket. Generally used outside rental clothing, although the appearance looks good, but too much repetition of diving will make the nylon material is squeezed and deformed. Bubbles that were originally in the inside were almost pushed to nothing. Without bubbles, there was no insulation at all.

Will you feel warm when you pee in your winter clothes?
It will warm your skin, but it will consume your body temperature. Two reasons: The first is that your body heat will be excreted with the urine and then exchanged with cold water outside in an anti-cold coat. The second is that when your perception under the skin tells the hypothalamus that it is warm, the hypothalamus will command the blood vessels in the area to expand so that the body will dissipate heat. This illusion will cause you to lose more body temperature. Although the cold skin feels uncomfortable, the insulation is better than warm skin. If you can avoid it, don't urinate in winter clothes. Inevitably, if you are healthy, urine does not have any effect; if urine is impatient, then when combined with seawater, it is odorless and colorless. So who distinguishes it?

The tropics are also very cold
Because the water is very conductive to heat, even if the water temperature is 27 degrees, people's skin will feel like 6 degrees in the air. So divers in the tropics face a kind of silent hypothermia. They never shivered or felt cold, but they were tired of diving and lost their enthusiasm. What people lose is not only body temperature, but also the driving force for diving. Therefore, it is recommended that wearing a thin waterproof suit in the tropics can take longer.
