Essay Example on Technology & Human Health: Effects of Devices on Nervous System & Sleep

Technological devices include a computer, cellular phones, smartphones, or any other devices that can be used to create, store, and transmit data in electronic form. These devices emit electromagnet waves and blue light that can be harmful to human beings. Therefore this context will mainly focus on the effects of technological tools on human beings such as effects on the nervous system and one's sleep. This is associated with being exposed to too much light at night from these devices before sleeping.

Firstly is the effect of blue light when it comes to sleep, especially among children. Most of the children tend to be troublesome, especially when it comes to quit watching the television or stop using their electronic gadgets before sleep time. Furthermore, these gadgets give them a motivation to go one using them because they are attractive (Johansson & Olle, 2009). The blue light radiated from these devices screens' can prolong the development of encouraging melatonin that increases readiness and resets the body's inward clock to a later calendar. This is getting worse, especially to teenagers whose circadian rhythms are moving regularly, making them feel conscious later, mostly during the evening time. At the end of it all, we find that restless or children that are inadequately refreshed end up having poor concentration in classes, which may end up affecting their performance.

Apart from that, blue light has a short wavelength that affects levels of melatonin more than any other wavelength. Light from these bulbs and LED lights can develop the same impact. In most cases, the pineal organ in the cerebrum starts to remove melatonin two or three hours before one gets to sleep. However, it is during the night that melatonin arrives at its top (Selhub, Eva & Alan, 2012). In this instance, when a person reads using blue light from gadgets such as a tablet during the night, they take a long time to nod off.

Nonetheless, they tend to wake the following day, feeling even sleepier, which makes doing chores difficult and unsatisfactory. To avoid this, therefore, parents should ensure that their children shut down hardware one hour or two before the time they are supposed to sleep. This will help enhance their bodies to create more melatonin.

On the other hand, there is the issue of mobile Cell, which ever since they were developed, have expanded drastically. Alongside this, the duration that individuals spend on their telephones has likewise increased forcefully in late decades. They emit a type of vitality known as radiofrequency (RF) waves, raising a few concerns about the security of PDA use. This has resulted in the question of whether mobile phones are associated with brain tumors. Most PDAs work through the transfer of signs to cell towers that are nearby using RF waves in which electromagnetic vitality is falling between microwaves and FM radio waves (Kumar & Girish, 2010). They are similar to other waves such as FM radio waves, microwaves, light is noticeable, and warmth in that all are the type of radiation that is non-ionizing. This means that they require more power to develop dangerous growth by harming the DNA inside cells. However, they are not quite the same as an ionizing form of radiation. Some of the examples include x-beams, bright (UV) light, and gamma beams, which can break bonds that form the compound of DNA. At some levels, however, RF waves can result in an increased temperature for the body tissues. But since the power radiated by phones is lower, it is not enough to raise temperatures of an individual.

These waves originate from the antenna of the phone, which is part of a phone held using a hand. They are strongest at the antenna and move one weakening as they travel away from the phone. Most of the people, when using mobile phones they hold them against their ears, which is close to the brain. The more the antenna is close to the head of an individual, the more one is at higher risk of getting exposure to RF energy (Habash et al., 2003). This means that parts close to the antennae are affected adversely, and the spread continuous. Researchers have detailed that the RF waves from phones produce impacts in cells of human being that may, at some point, result in the development of tumors. Some of the investigations that have been carried out include the use of rodents like mice to illustrate if RF my advance tumors brought about by other known cancer-causing agents.

A good example is a study carried out by the US National Toxicology Program. It found out that if a large number of guinea pigs or mice are exposed to RF waves with power emitted from the antennae over their bodies for nine hours each day. This was done before birth and continued for a duration of two years, which is similar to ninety years of human beings. Through this, it was found out that continued exposure led to the dangers of tumors called harmful schwannomas of the heart in male rodents. Apart from that, another investigation carried out illustrates that people using mobile phones may have different difficulties in the brain despite not knowing they are hurtful. From the examination, people spending time with wireless devices on their ears resulted in cerebrum tissues using more glucose than muscles on the other side of the mind. Glucose acts like fuel for the brain and provides energy to keep it working. Scientifically levels of glucose should go high in case one is moving or working. This, therefore, illustrates the use of mobile phones affects one's mind as the amount of glucose used may be unknown. When the cells of the brain are not working well, this leads to the crimpling of the nervous system.

Nonetheless, EMF may lead to harm in the structure and capacity of the sensory system. This is since the likelihood EMF introduction to one's body is unknown may end up not being peril right away. For instance, microwave frequencies underneath 3,000 megahertz can penetrate the external layers of the skin, which is invested with necessary tissues resulting in the majority of organic impacts of warming that may lead to one's demise (Bisht et al., 2001). There are two types of Brain caused by electromagnetic radiation, which are dangerous tumors and generous tumors. These affect cells if the mind causing difficulties to one's health.

EMF results in harm due to individuals using mobile phones for a long period. Misfortune of hearing develops in a person if he or she uses a wireless device with higher recurrence for a longer time. Practically for one to hear the person who is calling them, they hold their mobile phones near their ears. This radiation harm the inward ear, and a longer duration of using phones is destructive as it actuates the cochlear receptor through a similar procedure that is engaged with the average hearing. Through this, what is heard by the individuals exposed to the microwave radiation. A large portion of the youth experience hearing impairment because of increased use of the phone.

A good example is where people using mobile phones every day for a duration of two to three hours end up with incomplete deafness. There is a large number of people in their 20s working in showcasing and teleconsulting experts, which involves the use of the mobile phone. They have led to the expansion along these lines whereby PDA radiate radiofrequency, which includes attractive fields and swaying electric, which collaborate adversely with the cells of plants, people, and creatures. The radiofrequency electromagnetic radiations are being made for the specialized remote gadgets, which increasingly affect the wellbeing of a human being. The radiofrequency is associated with the tissue near the versatile that works with the sound-related nerve. Therefore when a cell phone is being used, the inner ear and parts around its skin develop microwave power and radiofrequency, which hinders an individual from hearing. This means the sensory cells for hearing in the nervous system have been destroyed.

EMF is also associated with Bluetooth innovation, which lately is connected to health issues such as cerebrum tumors and births of imperfect infants, among others. From the context, one has already identified that RF radiation influences the body thermally. Therefore this means that these radiations have the properties to change one's cell structure, which results in proneness to diseases. Bluetooth innovation among devices is not grouped among phone radiation. People over some time have had thoughts that low levels of RF radiation have no harmful effects. This, however, is not the case since if one is exposed for a longer duration over a period of years, he or she develops some health issues. An instance of Bluetooth innovation is the microwave, which is linked to various medical problems. That is from studies carried out by different scientist Bluetooth devices produce RF radiation that is responsible for the break of blood cerebrum obstruction. This is the part that forms a boundary that acts as the last line of defense to protect one's body from harmful synthetic compounds. Most medical specialists state that once the barrier is killed, one gets inferior to disease-causing agents and thus can get infected by any disease easily. This leaves the nervous system open affecting individuals' minds.

From the above context, therefore, one can conclude that blue light and electromagnetic waves are harmful to one's health. Therefore for better conditions, one should ensure they reduce the use of artificial light. For instance, they should use diminished red lights for the night. Red light has minimal capacity to move circadian musicality and stifle melatonin. Apart from that, people should ensure they go to bed early and avoid looking at the screens before going to bed. By any chance, one takes a night shift and spends most of the time piking mobile phones from clients he or she should ensure protection by having protective gear that blocks EMF radiation. This will aid in ensuring that health facilities are able to curb most of the nervous system effects. Nonetheless, the life span of one is extended since he or she is not prone to disease association with electromagnetic radiated waves.
