How to wash diving cold-proof clothing? Why can't you dive if you have a cold?

Diving is a relatively professional leisure sport, which includes snorkeling, deep diving, free diving, etc. It is generally an activity carried out in seawater. There are specially designed cold-proof clothing for diving to keep warm, but even so, you cannot dive if you have a cold.

How to wash diving cold weather suit

Before washing, we should first check for damage, especially the seams of the clothes. Then check the elbows and knees, which are often bent, to see if they are worn out. It should be noted that most cold-weather clothes are made of nylon fabric, which will stretch, so you need to pull it slightly when checking to see if there is any hidden wear.

After checking again, we will start washing. Use neutral detergent or cold weather detergent and warm water to wash. Flushing can remove dirt, sediment and salt, but avoid high pressure water and pull the zipper back and forth several times in clean water.

After washing, hang it on a hanger to dry in the shade. Use a flat hanger to avoid shoulder marks. Turn the cold weather jacket inside out to dry. Do both sides to ensure they are completely dry. This will prevent the equipment from getting moldy. The ideal place to dry the equipment is in a place where it is not exposed to direct sunlight and where there is good air circulation.

Why can't you dive if you have a cold?

Reason 1: Lack of physical fitness

First of all, you need to know that diving itself is an extreme sport. Although you are in the water all the time, it actually consumes a lot of energy for the body, and the physical condition will affect the whole experience of diving. It's like asking a person to go running when he has a fever, the feeling will definitely be terrible.

Reason 2: Unable to balance ear pressure

When diving, for every 10 meters we dive, we will experience 1 times the standard atmospheric pressure. Simply put, the deeper we go, the more sea water there is above our heads and the greater the pressure we will experience.

Therefore, as we dive, the pressure on our ears increases, and ear discomfort becomes more likely. This is because the pressure pushes our eardrums and surrounding tissues inward.

Reason 3: Reverse obstruction of the lung cavity

The most important rule of scuba diving is to keep breathing! Never, ever hold your breath!!

This is because during a dive, as the surrounding water pressure increases, we inhale more gas than normal in order to maintain the balance between the lungs and the outside world.

After catching a cold, the trachea becomes easily congested and swollen, causing the expanded air in our lungs to be unable to be discharged in time and be trapped in the cavity of the body. This is a case of reverse obstruction.

How to balance pressure while diving

The main method is to pinch your nose and gently blow air through your nose to transport air from your throat to your ears and nasal cavity. At the same time, you can exhale into the mask through your nose to balance the mask.

Continuing to dive without completing ear pressure equalization will cause the ear cavity to be unable to equalize, and in severe cases it will cause ear fluid accumulation and rupture of the eardrum.
