How Too Much Screen Time is Damaging Your Health

      Comments Off on How Too Much Screen Time is Damaging Your Health

The rapidly developing tech world has opened us up to new possibilities. We interact with one another in real-time at the press of a button, or via moving pixelated pictures. The whole world is available to us via a digital screen, and sometimes we are unaware of how much time we spend with our eyes glued to one (or two, or three—who uses just their computer these days?)

Research has shown that too much screen time can have serious effects on one’s health over time. While it is nearly impossible to eliminate one’s screen time entirely (it is the 21st century after all), here are a few reasons you might consider cutting down on how many hours a day you spend looking at your smartphone, tablet, computer, etc.

Screens cause eye strain.

Possibly the most obvious effect of too much screen time, eye strain has become increasingly common over the last decade. Digital screens emit blue light, which has a significant effect on our circadian rhythms, especially if you are exposed heavily to it at night. Aside from keeping you awake (blue light suppresses the hormone melatonin, which is a key hormone needed for sleep), looking at a screen for too long—and especially in the dark—can strain your eyes and can even damage the retina over time.

A good rule of thumb for reducing eye strain is the “twenty” rule. If you have been glued to a screen for twenty minutes, look away and at an object at least twenty feet away, and fix your eyes on that object for at least twenty seconds.

The brain rewires itself according to screen addiction.

This takes longer to happen in adults than it does in children, but studies show that addiction to gadget use and the subsequent screen time can affect the brain’s grey matter. Grey matter is responsible for the transmission of signals from neuron to neuron. The more exposure to screens, the greater the chances for screen addiction, leading to an eventual decrease in grey matter that affects the way signals between neurons are transmitted. This later results in an overall decrease in cognitive performance. (Another way of putting it is: spending too much time looking at screens can, theoretically, make you stupid.)

Too much screen time affects metabolism.

A study in 2008 showed that people who generally spend more time looking at their screens are those who lead sedentary lifestyles. While metabolic syndrome is not strictly caused by looking at screens, the data showed a strong correlation between the amount of screen time and the subsequent development of metabolic syndrome caused by several hours of physical inactivity. The syndrome is a mix of acquired diabetes, high blood pressure, and obesity—all of which you get from sitting still.

Another effect of spending several hours on a computer, tablet, or smartphone is poorer cardiovascular health, which leads to a greater risk for developing fatal heart disease later in life; in 2011, researchers found that adults who had plenty of screen time increased the likelihood of their death by a whopping 52%.

Exercise and a healthy diet—combined with actually logging off the tech—can help significantly reduce that statistic. If you’re going to be spending time in front of a screen, you may as well be outside. Why not try an setting up an outdoor movie theater and let the kids enjoy both nature and a great flick.




Three Legged Mobility: The Importance of Assisted Walking

mobiilty aids

Needless to say, we are all destined to grow old some day. And in the twilight years of our lives, things, inevitably, start becoming more difficult for us in terms of mobility. When our limbs begin to be less responsive, mobility/walking aids and other such forms of assistance are, therefore, needed to support us. There are numerous disabled and elderly individuals out there who require support from mobility equipment in order to compliment their need to stay independent.

What are Mobility Aids?

These are equipment and devices that are intended to support the elderly or people who experience pain in weight-bearing joints due to disease or injury. In addition, mobility aids also provide users with numerous health benefits as they improve balance and assist the disabled to sit, stand, and keep moving.

Health Benefits of Mobility Aids

  • Improved balance and stability

Whenever the elderly walk over uneven surfaces, various obstacles can make it difficult for them to maintain proper balance. For instance, when they are going uphill, stepping on rocks, or hiking on loose dirt, proper support for balance and stability is essential. Mobility aids thus help in stabilizing body weight and consequently reducing the risk of slipping and falling. They also assist on hilly terrain by providing balance, especially when fatigue sets in and the muscles become less reliable.

  • Joint and back health

Mobility aids also help in the redistribution of the body’s mass by preventing a situation where all your weight comes down on your hips, knees, and back. They displace your body mass from your lower body and back and support it through the walking aid and your arms. This is greatly beneficial in reducing pressure on the muscles and joints and should be particularly helpful to those who suffer from back problems and arthritis.  Additionally, walking aids foster proper body posture, especially in the upper back. Proper posture is crucial as it redistributes mass evenly which improves back health and reduces the risk of injury.

  • Improved mobility

Walking aids drastically improve an elderly person’s mobility as it helps them maintain an active and healthier lifestyle. It is thus little wonder that these devices have gained such immense popularity among the elderly who use them to move around better and for any other things that they need to do. This gives them more confidence as they are likely to be more energized in their day to day activities.

  • Avoid falls and trips

Mobility aids can assist older people to not only maintain balance, but minimize their risk of falling. Falls are a common phenomenon in older people and the risk of falling invariably increases with age. A third of people aged 65 and over, rising to over 40% in those over the age of 80, fall each year, compared with 8% in the middle-aged.  This can be mainly attributed to psychological changes that are associated with the normal aging process which increase reflex times, reduce balance and, consequently, increase the risk of falling.

Undoubtedly, it can be quite depressing going through life feeling like you cannot do everything that active, healthy people around you are doing. With mobility aids such as the highly acclaimed 3 wheeled rollator, the elderly are assured of the best quality of life as simple tasks are made as easy as possible. Check out the 3 wheeled rollator reviews to see how mobility aids are benefitting those in need.

1. Record maintenance and taking care of patients

2. Dental radiography and infection control

3. First aid emergency services

4. Oral diseases and how to prevent them

5. Offering support during treatment

For qualification, one needs to undergo either of these approved courses:

• Foundation Degree in Dental Nursing

What does a dental nurse do?

As aforementioned, dental nurses provide support to dentists in matters concerning dental care. This support ranges from taking patients record to handling and sterilizing the dental kit and includes:

• Preparation of materials such as those used for teeth filling

• Getting saliva and water out of the patient’s mouth during treatment

• Passing of instruments from the dental kit to the dentists or therapists

• Ensuring the patients are comfortable and relaxed

In addition to the above, the nurse helps out at the reception area. This is common during busy periods. The nurse sorts out and books the appointments and collects payment. It is common for them to apply their skills and reassure patients too to put them at ease.

Working hours

The working schedule is normal. Normal working hours, that is 9am to 5pm during weekdays i.e. Monday to Friday although this depends with the practice. Some open during evenings too and allow for part-time work sometimes.

A nursing uniform is a must have. In addition, surgical gloves and safety glasses are used to minimize the threat of cross-infection


Those starting out in the NHS earn around 16000 euros while their qualified counterparts earn between 19000 to 22000 euros.
