Below is a video that'll show you why you should have a window cracked, and would want to cover your face when in social situations.  (ie wear a mask)

Their results: "We conducted a study among healthcare workers (HCWs) exposed to patients with severe acute respiratory syndrome (SARS) before infection control measures were instituted. Of all exposed HCWs, 7.5% had asymptomatic SARS-positive cases. Asymptomatic SARS was associated with lower SARS antibody titers and higher use of masks when compared to pneumonic SARS."

I know that this might not be in concordance with CDC guidance, and so ultimately when you disregard them, you'll be doing it after your own informed decision.  Please, read past this blog if you need to.  I don't believe that folks in the Far East are wearing masks because of superstitious or religious belief; they are wearing masks because its been proven again and again to reduce spread of contagion.  Around the world people have used variants, and I personally would not think twice to adding some essential oils to my cloth mask, although doing such a thing might also not be in accordance with CDC guidelines as of the present. 

The message you should get bottom line is this: wearing a mask does not eliminate your risk of getting an infection by some other route besides your nose and mouth, nor does it perfectly filter the air that's reaching your mouth and nose.  But it does do a pretty good job of it, and I'll argue that pretty good is better than none at all. 

There's more eye candy on their site if you're interested. 

The findings of the study was that a homemade mask should be a "last resort" but "better than nothing" at all.  Duh. 

Coronavirus is about 1 micron in size (100nm).  This is about the same size as Influenza, which is 0.8-1.2 microns (80-120nm).   An effective filter should be able to trap particles that small. 

According to SmartFilters, who read the whole study, (I didn't)   "The homemade cotton masks captured 71% of 0.65-1.1 micron particles, compared with 86% for the surgical mask. Although the surgical masks captured 15% more particles, the cotton masks did surprisingly well. The researchers concluded that homemade masks would be better than nothing"

In the words of a redditor:

"Based on size alone, small amounts of virus could in theory fit through gaps in the microfibre, at differing rates for different masks (N95, N100 etc)... But:

As I outlined above, the less your viral load, the better.  Take every measure that's reasonable and practical to reduce that load for yourself and others around you that you're going to be depending on. 

If you aren't getting good sleep, now's the time to try and fix that.  Make a point of going to bed early.  It's better to go to bed early and wake up early than stay up late and be groggy later. 

I'm looking for the link to the study, but a week or so ago I read one on sleep and coronavirus.  It found that after missing sleep for 3 hours on just one night made people three-times more likely to contract the virus, and suffered three-times-worse symptoms the next day.

I'd just be repeating what Doctor Sleep says, and so I'll just send you right over to his site.  He will suggest blue-blocking glasses.  It's good advice, and they work, but the only caveat to his approach is that I prefer to recommend melanin glasses.  They're also amber, but the pigment is made from real melanin.  Melanin lenses improve melatonin production by restricting UV and blue light, allowing the pineal gland to operate in "night time mode."
