‘Amputees living near cellphone towers may suffer from increased pain’

New York: A new research suggests that amputees living near cellphone towers that produce radio-frequency electromagnetic fields may suffer from increased pain.

“Our study provides evidence, for the first time, that subjects exposed to cellphone towers at low, regular levels can actually perceive pain,” said senior study author Mario Romero-Ortega, associate professor of Bioengineering at University of Texas at Dallas, US.

Until this study, published online in the journal PLOS ONE, there was no scientific evidence to back up the anecdotal stories of people, who reported aberrant sensations and neuropathic pain around cellphone towers, the researchers said.

“Our study also points to a specific nerve pathway that may contribute to our main finding,” Romero-Ortega noted.

Most of the research into the possible effects of cellphone towers on humans has been conducted on individuals with no diagnosed, pre-existing conditions.

This is one of the first studies to look at the effects of electromagnetic fields (EMFs) in a nerve-injury model, Romero-Ortega said.

The team hypothesized that the formation of neuromas — inflamed peripheral nerve bundles that often form due to injury — created an environment that may be sensitive to EMF-tissue interactions.

To test this, the team randomly assigned 20 rats into two groups — one receiving a nerve injury that simulated amputation, and the other group receiving a sham treatment.

Researchers then exposed the rats to a radio frequency electromagnetic antenna for 10 minutes, once per week for eight weeks.

The antenna delivered a power density equal to that measured at 39 meters from a local cellphone tower.

Researchers found that by the fourth week, 88 percent of rats in the nerve-injured group demonstrated a behavioral pain response, while only one rat in the other group exhibited pain at a single time point, and that was during the first week.

“Our model found that electromagnetic fields evoked pain that is perceived before neuroma formation; subjects felt pain almost immediately,” Romero-Ortega said.

The researchers believe that the protein TRPV4, which is known to be a factor in heat sensitivity, could be a mediator in the pain response for these rats. (IANS)(Photo: www.networkedindia.com)

With a brand new year most of us contemplate on our flawed decisions and make resolutions to do better in the coming year. One of the most important resolutions that is made by many is to live a healthy lifestyle and practice a sustainable fitness regime.

Studies suggest that many resolutions are broken within the very first month of the year, while several others give up as the year ends due to irregular working patterns or low will power or even lack of perseverance. Amaresh Ojha, CEO and Founder, Gympik suggest few ways that might help one to stick to their fitness resolution.

Self-awareness

Change starts when you measure where you stand and how far you need to go. You need self-awareness before you can achieve self-improvement. Keep a regular check on your growth cycle and constantly observe and read what can help you improve, in terms of both your health and wellness.

Maintain a daily journal

Maintain a workout journal to record each workout you do. It is interesting to look back when you see the progress you’ve made. Depending on your capability, make smaller changes such as run 100 meters more than the past week, do 1-2 more reps more with an increased weight, increase your workout time by 10 minutes etc.

Don’t skip breakfast

You must not skip breakfast as it is the first meal of the day and it helps in breaking your overnight fast. If you skip your breakfast, you add to this fast which might affect your metabolism. So, make it a habit to have breakfast within two hours of waking up. Consuming a healthy breakfast reinstates the glucose levels in the body and lowers your stress levels.

Don’t beat yourself up

You may skip a yoga or cardio session once in a blue moon, which won’t make much of a difference. But if you skip them for days this will disrupt your healthy lifestyle and you will notice strength losses. In order to return your body to pre-holiday levels, begin with 10 to 12 minutes of cardio at a normal intensity. Then gradually, add time till you get back to your previous workout duration. To return to weight training, use the same resistance as before but lessen your reps by about a third and then gradually increase going back to your normal workout patterns.

Eat at regular intervals

It is important that you plan your meals to avoid last-minute hunger-driven decisions which may lead to unhealthy eating habits. Once you disrupt your eating patterns, it is difficult to get back to the rhythm. So, eat as per your diet but at regular intervals so that you do not gain or lose weight in an unhealthy way.

Use health monitoring/fitness apps

Use fitness and weight monitoring apps to have a better understanding of your fitness journey. Install your favourite fitness app and keep a track of your everyday growth.

Exercise wherever and whenever

Do not restrict yourself to gyms and aerobic classes when it comes to exercising. Walk a few extra miles, whenever possible. Moreover, research says that household chores like cooking, laundry, cleaning your car or mopping burn a substantial amount of calories.

Take one step at a time

Last but not the least, go ahead even if you take small steps. It happens to many of us often that if we miss a day of exercise or have a cheat day, we lose focus and feel like we have failed. But that is not the case, we must understand that we are in a continuous process of improvement and every time we fail, there is always the next day to get on track. Do not feel pressured to do it all at once or nothing at all. (IANS)
