Things are starting to return to normal despite the country still facing increased cases of the virus, and as the need for more precautions becomes even clearer, some feel they don't need to adhere to medical guidelines - often citing spurious medical facts.

But one doctor has proven them all wrong with a test that shows no negative effects on his oxygen levels during mask-wearing - even while long-distance running.

We all know we should be wearing masks, right?

They play an absolutely crucial role in limiting the spread of coronavirus.

And right now, we need that more than ever.

Our grip on the virus's spread is rapidly slipping out of control.

And although some complain about face masks ...

One doctor has gone above and beyond to prove they are truly safe.

Think masks make it hard to breathe?

Think again.

Because masks don't actually impair oxygen levels at all.

And this test proves it!

The pandemic has really brought out the worst in people...

Right now the United States is the worst affected country in the world but is it because people are acting so recklessly?

Even though everal states have declared states of emergencies, it seems as though some people just don't care.

And with the uproar from anti-maskers, it seems things are only going to get worse.

Bizarrely these people feel they don't need to take the same precautions as the rest of us.

As if they are immune to the deadly virus.

Although the country is still experiencing increased cases of coronavirus, things have started to get back to normal, we've all had to adapt to a new way of living.

Despite these subtle changes, people are still struggling to adapt to these essential precautions.

In the past few weeks, we've been trying to get back to normality...

With things beginning to reopen again.

But whilst things are getting back to normal, we must still take precautions.

This is very important because we need to stop the spread of the virus.

In fact, some precautions are becoming mandatory in some places.

Including here in the U.S.

In some states, it has become mandatory to wear a face mask on certain occasions.

For example, in some retail stores like Costco, on public transport, and even in restaurants.

Some people are choosing to wear a face-covering regardless.

To provide them with peace of mind. I mean, that seems to be a good idea. Along with that, people are carrying around bottles of hand sanitizer and wet wipes.

But there are issues with face masks that many people have discovered.

Not only are they in short supply, after most countries in the world are requiring PPE.

But the issue that some find these masks uncomfortable.

Particularly when they are worn for a long period of time.

They claim the masks also make it hard to breathe whilst wearing.

But the uncomfortable nature is a small price to pay for the safety they could provide.

Many people have resorted to making their own masks.

Both for themselves and for essential workers, as they are not being provided with enough.

Despite this, health experts have stressed their importance.

Healthline describes them as "crucial in the fight against the pandemic." They stressed that this rule is to protect others and not yourself. Wearing a mask reduces the transmission of the disease by at least half.

A lot of people have decided to take on board these expert suggestions...

But sadly, not everyone agrees...

So one doctor has decided to take on the mask-skeptics.

Dr. Tom Lawton from the Bradford Royal Infirmary in Yorkshire, England, has come up with a clever experiment to prove the naysayers wrong.

He's been going on long-distance runs in his mask to prove his point.

Then testing his oxygen levels - which never change significantly, regardless of his face covering.

Yep, masks aren't dangerous at all!

And if Dr. Tom can wear one while running 22 miles, surely you can while going to get groceries.

He even shared pics as further proof.

Pretty hard to argue with this.

So there you have it - masks are good.
