Is there formaldehyde in mahjong seats?

Mahjong mats are a kind of cool mat that many people choose in the summer. This kind of cool mat will feel very cool when sleeping, so it will not cause heatstroke. However, mahjong mats also contain formaldehyde, so people must first measure the formaldehyde content when purchasing mahjong mats. If it is too high, try not to buy it.

1. Check whether the color is uniform, light green or bright yellow is preferred. Then spread the mat flat to see if the weaving is tight and even.

2. When purchasing a mat, it is best to smell the mat first. If it smells a bit pungent, it may contain formaldehyde.

3. Touch the front and back with your hands to check if there are any burrs or burrs, and whether it is flat and smooth.

4. After purchase, you can scrub, dry and expose it to the sun, and the formaldehyde content will be significantly reduced.

In addition, choosing a cool mat according to your physical condition is one of the best ways. Below are four types of cool mats suitable for people with different physical conditions. You may want to refer to them.

1. Suitable for people who are very afraid of heat and have yin deficiency and internal heat

1. Cooling mat: Fix the special potion inside the mat material, and when people lie on it, they will have a freezing feeling similar to lying on ice water. If we rank them by degree of coolness, the ice mat would rank first.

Disadvantages: It is very cold and is not suitable for use by the elderly, children and people with weak constitutions. Moreover, the surface material and internal filling of the cooling mat are made of chemical composite materials, and some people may be allergic to it after sleeping on it for a long time.

2. Jade mat: The second coolest mat is made of jade slices strung together. There is a certain gap between each piece of jade, which increases the breathability of the mat. It has a calming and soothing effect and is very effective for treating irritability and insomnia.

Disadvantages: It feels cold to the touch and is more suitable for young and middle-aged people who are afraid of heat and have yin deficiency and internal heat.

3. Bamboo mats: cool, durable and moderately priced. The most common ones are water bamboo mats, bamboo mats and mahjong bamboo mats strung together with small bamboo pieces and plastic ropes. The mahjong mat is the coolest and most flexible, and has a good massage effect on the back.

Disadvantages: poor air permeability, high hardness, and easy to break when the bedding is uneven. Bamboo mats with spray-painted patterns may cause contact dermatitis. It should be noted that due to the high external temperature in summer and the increased body temperature of human beings, the thick plastic rope tubes in the mahjong mat are easily volatilized and toxic when heated, and are not suitable for long-term use.
