Advantages and Disadvantages of Microwaves

Microwaves are a part of the electromagnetic spectrum, which also includes radio waves. They are electromagnetic radiation that has both electric and magnetic components. When microwaves pass through matter, they cause the molecules to jiggle or vibrate. They do not have enough energy to break bonds, but they can cause a molecular friction and dielectric heating that causes the molecules to reorient themselves. The continuous re-orientation causes energy loss and results in heat generation.

Microwave ovens are one of the most convenient appliances in the kitchen. They cook food in a fraction of the time it takes conventional ovens. They are relatively safe, too. The hot air is confined within the cooking chamber so there is little danger of burns. They are easy to clean and have a sleek, modern look that complements most kitchens.

Another advantage of microwaves is their portability. They are smaller and lighter than conventional ovens, so they can be taken with you on the road. They are also very versatile, able to be used for everything from reheating leftovers to defrosting chicken or steaming vegetables.

While it is obvious that microwaves have many practical uses, they may not be all good for you. Long-term exposure to microwave radiation has been associated with cognitive deficits. Studies using the Morris water maze test have shown that microwave radiation can alter learning and memory abilities. These effects are mediated by various mechanisms, including oxidative stress, apoptosis and protein synthesis.
