The basic function of a signal jammer is to block the reception between a mobile phone and the cell tower. The device is operated by government officials, especially those in the military, during hostage situations or threats regarding explosives that are triggered using cell phones. How do signal jammers function? Signal jammers are known through various terms like cell jammers, text stoppers, and signal blockers. The device blocks the radio frequency of the area in which it is used. So, here there is a blockage of all communication by creating signal traffic. Any mobile devices in the area can neither send nor receive calls and texts. The best signal jammers can block communication for a wide area. Why are signal jammers used? Many people feel signal jammers are appropriate to use in places where the use of mobile phones is considered disruptive, like in educational institutes and libraries. However, since these jammers can cause problems with not only cell phones but also WiFi, GPS, and police radar, the Federal Government in the country has banned their use. Only government officials, especially officers of law and military use some of the best signal jammers to get an upper hand during dangerous or life-threatening situations. Does a signal jammer affect cell phone signal boosters? Cell phone boosters are used to improve the reception in rural areas or while on the road. They strengthen an existing signal; however, just like cell phone signals and WiFi among others, signal jammers can interfere and block a cell phone signal booster. Can you buy signal jammers in the country? It is illegal to use, buy, or sell signal jammers in the U.S. and most other countries. This is because these devices can easily cause disturbance in important or authorized radio communications. According to the Federal Communications Commission, these jammers can risk breaking the line of contact in the public during critical scenarios or interfere with official communications. Such public safety issues cannot be ignored. Also, The Communications Act of 1934 legally protects radio frequencies, so any interference with official radio broadcasts is against the law. Although signal jammers are frequently seen in movies or TV shows, entertaining the idea of using one in real life is a bad idea. This device is very helpful and should only be operated by authorized officials. Such a device may cause more harm than good if it is in the wrong hands.

Lungs, an integral part of the respiratory system, hold oxygen which is then supplied to the rest of the body through the bloodstream. It is essential to keep the lungs healthy to maintain optimum oxygen intake. However, there can be things in the environment that can trigger lung damage. This article lists five such household factors that can trigger lung damage, which can, in turn, cause diseases. Let's check them out.

Mold
Mold is a type of fungus that grows on damp surfaces and corners. It is common in houses with issues of leaking pipes. The fungus releases spores in the air and can trigger a severe reaction in those allergic to mold. The response is relatively severe in people with lung damage and diseases like asthma and COPD.

Carpet
Carpets add to the allure and warmth of our homes. But there are some other harmful things that they add. Carpets can act as a storage space for dust mites, cockroach droppings, mold, dander, pet hair, and other allergens. These are released back into the air often. As a result, it is advisable to clean and vacuum carpets multiple times a week to ensure they do not work as carriers for lung-damaging components.

Flour
Baker's asthma is a common condition among bakery workers. It is caused by the dust and flour particles that saturate the air and are transported with humans as vectors. Those who suffer from this have a difficult time breathing. Baker's asthma can also be detected in people who live close to bakers, including their family and friends.  

Candles
Candles are made from paraffin, a petroleum-based product. When lit, candles release chemical-fueled fumes into the environment that can trigger allergic reactions in people. This reaction is enhanced in people with pre-existing conditions like COPD, asthma, allergies, and low immunity. Regular use of paraffin candles is, therefore, to be avoided. For people that are often surrounded by candles, it is advisable to use soy or beeswax candles.

Humidifier
There is a reason why appliances like air conditioners and heaters undergo servicing regularly. While all these technological advancements were created to make things easier for us, they can also contribute to weakening lungs. They could act as a breeding ground for fungus or other microorganisms that can lead to lung damage and other respiratory conditions.

Did you ever realize the actual benefits of what trampolining does to adults? Using a trampoline for fun and otherwise does wonders for your health if you practice on the trampoline every day. It's not only a fun way to spend time but is also an excellent way to get into the fitness world and get its health benefits. Trampolining is a form of exercise. Many of those who are not so interested in running or jogging can benefit from simply jumping about on the trampolines. It comes in two designs – mini trampolines or rebounders. Anyone without any age limit can enjoy on trampolines and maintain a healthy body. This activity is considered three times more beneficial than running. For example, bouncing around eight times is almost the same as a 30-min run. Astounding, isn’t it? Other many benefits of trampolining are –

• Increases oxygen capability.
• Stimulates metabolism.
• Improves the sense of balance.
• Strengthens cardiovascular health.
• Develops energy and sense of vitality.

Cardiovascular Fitness: Regular workout with trampolines increases muscle strength and improve pulse rate brought about by the jumps. The oxygen starts to circulate firmly, and it improves the overall health condition. Little Impact: Trampolines are not like just any other sport. Comparatively, they have a low impact on the joints. The acceleration and retardation movement infused by the trampoline pad take off 80% of the shock of the joints. Thus, it is harder to jump on hard surfaces such as roads. Hence, trampolines have a low impact and protect the joints/muscles while exercising. Stronger Bones: Is there anyone who doesn’t want healthy bones? Trampoline exercises are vigorous, and the repeated jump actions slightly stress the bones. This way the musculoskeletal system develops bone mineral content. Over time it becomes a great boon to prevent osteoporosis or brittle bone disease. As the trampoline pad is resilient to a large proportion, the bones and joints are significantly protected and also strengthened. A workout that works against gravity is expected to improve the overall health of an individual. However, if you have any chronic diseases, it is better to consult with a doctor before you just start jumping in the air.
