With the prevalence of the concept of "smoke-free kitchen", more and more families use microwave ovens as the main cooking tool. But scientists have recently pointed out that improper use of microwave ovens can lead to skin cancer, cataracts and even infertility.

In modern society, people's lives are faster and cooking is easier, so microwave ovens have become almost a kitchen necessity. But Thailand's Chiang Mai Medical Science and Technology Center scholars tanmalat recently told the media, microwave ovens in the use of strict requirements, it is the principle of action is to release the frequency of 2,450 Hz microwave, in the closed oven constantly reflecting, so that the water molecules in the food to the same frequency shock, and ultimately, molecules within the food to produce friction between the heat. However, if there are cracks in the inner wall of the microwave oven, or if the manufacturing materials are defective, then the rays inside the microwave oven will leak out, thus causing harm to the human body.

Tantamarat said that in order to prevent microwave leakage, we should develop the habit of frequently checking the inner wall of the microwave oven and the door lock, and also pay attention to prevent the impact of the inner wall and vigorously close the door when using the microwave oven.
