Wearable Technology: are Physical activity and Fitness monitors useful ?

Once we come out of this COVID pandemic, everyone’s attention needs to be focused on the obesity pandemic.

During the COVID pandemic, lot of people started to focus on their physical fitness. People invested in Home Exercise equipment and in wearable technology such as Fitness monitors.

Even before this pandemic, lot of people have started using Fitness monitors.

Are they any good?

A recent study published in British Medical Journal (BMJ) looked the effectiveness of physical activity monitors.

The study authors looked at more than 120 trials involving more than 16 700 participants.

Most of studies they looked at were either European (31%) or North American (40%). Most of these studies included healthy participants (47%), although some included overweight participants (17%).

They found Fitness monitors are generally safe and help to increase physical activity.

Whether the Fitness monitors will help overweight people to lose weight permanently over long term needs further investigation.

Are mind numbing jobs associated with dementia ?

Yes.

It’s the principle of “use it or lose it”.

Body muscle strength can be lost quickly if it is not used. That’s why many people try to go to Gym and exercise regularly.

The same principle seems to apply to the brain.

People who are using their brain regularly with stimulating jobs are better off than people who are doing mind numbing jobs when it comes to dementia later in life.

So if your are not using your brain that much in your job, perhaps you need a “brain Gym” outside your work !

Covid-19: Can you catch the coronavirus while exercising outdoors?

Yes, you can.

But the risk depends on how long and how close you have been in touch with an infected person.

Momentarily passing someone while jogging is extremely unlikely to lead to an infection.

But face to face contact lasting many minutes with a friend or someone who is infected can lead to an infection.

There is a good article on how BBC website.

Does air pollution in cities make your jogging and walking less beneficial ?

Yes, air pollution is now being recognised as an important cause of death in major cities and towns.

So avoid major roads and very busy streets.

Any benefit you might accrue from exercise can be wiped out by heavy air pollution if you are jogging on a heavily congested road.

Walking is good exercise

New year. January. First month of a New year – it’s the time of year many people take a look at their lifestyle and vow to eat better, exercise better and live better.

Many people consider Gym or Health Club membership.

But Exercise doesn’t need to cost a lot. Being active, doesn’t need to be regimented.

Simply walking anywhere is good compared to no exercise at all. Walking in the Park or Quiet streets has lot of benefits.

Good article in BBC on the benefits of walking.

A word of caution though !

Avoid Walking or Jogging near busy roads so that the benefits of walking are not negated by pollution.
