No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Hello.

Twice a day I ride bicycle for 2km along a busy city road (2x2 lanes at 50km/h).

From a health standpoint, is it recommended to wear a face mask (N95)? Does it stop exhaust fumes?

Thank you.

Oxygenation may be a concern, depending on how winded you get. I'm not saying that you'll pass out or anything so dramatic, but studies have shown that even mild hypoxia can effect our ability to make complex decisions, which may be an issue when biking in traffic.

Those without respiratory issues don't have oxygenation issues while wearing masks.

The same air is going into your lungs, the only difference is your diaphragm has to work harder due to the filtering effect of the mask. If it can't manage that, then you are likely already on oxygen due to low tidal volume and chronic hypoxia.

You can buy a pulse oximeter from CVS for like $20 and test this yourself if you don't believe me.

Woah, man it's cool, I believe you. No need to threaten me with a trip to CVS.

We should all buy pulse oximeters anyway because they're cool.

As much as I hated that excuse during the pandemic, I think I’d have trouble breathing when wearing an FFP3/N95 mask while cycling. Granted, I’m talking about cycling as a sport, not for commuting (though I tend to have a decent speed while commuting). Going 30 km/h I really need my air to keep it up.
