Yes. The acid in the food can harm the enamel and brushing it to soon can remove it. So wait at least 30 minutes, brush before or avoid acidy foods. Mayo Clinic: If you've eaten an acidic food or drink, avoid brushing your teeth for at least 30 minutes. These acids weaken tooth enamel, and brushing too soon can remove enamel. If you know you're going ...

This is something people have been studying since 1847 when Ignaz Semmelweis hypothesized that childbed fever was caused by physicians assisting at deliveries without cleaning their hands (sometimes coming directly from autopsies or cadaver dissections). Since then there have been thousands of experiments performed to find the best methods of hand ...

Hands play a major role especially in the transmission of blood-borne, fecal, and respiratory tract viruses. Hand washing after use of bathroom aims at preventing the transmission of pathogens, which rely on faecal-oral transmission, such as rotavirus, noroviruses, enteroviruses in some cases hepatitis A virus (1). It prevents those pathogens from reaching ...

While I cannot comment on the issue of laying on your back causing acne, I hope my answer helps with your concern for prevention. There is some evidence that glycemic index (GI) is related to more severe acne. One study examining the diets of 287 people from ages 18-25 with no, mild or severe acne, found that those with worse acne had greater dietary (...

The hygiene hypothesis For some reason I hold the opinion that the immune system needs to be kept busy so it wont get weak In scientific terms, this is known as the hygiene hypothesis. It was proposed in 1989 by Strachan and is about whether people who have been exposed to a lower amount of pathogens in their childhood are more likely to develop ...

There are a few other active ingredients you could try for dandruff (seborrheic dermatitis), if that's what's causing your problem. Keep in mind that it might actually be a different problem, such as eczema or scalp psoriasis. From a quick internet search, the active ingredient in "Dettol Anti-bacterial Soap" is cholroxylenol, is that correct? If so, here ...

This is an interesting question. You are certainly not an isolated case. The "origin" of foot odor has been examined in many studies. This study conducted by Marshall et al focused on the microflora found on normal feet (no foot odor) and compared it to feet with foot odor. They reported a higher population densities of staphylococci and aerobic coryneform ...

Urine is not sterile, not while in the bladder and certainly not when it comes out. Contrary to dogma that urine is sterile in the absence of a clinical urinary tract infection (UTI); our research team and others have recently shown the existence of a urinary microbiota in individuals with and without lower urinary tract symptoms From "Bacteria isolated ...

In principle: yes, the gut microbiome can be altered by external exposures. It is the large but and a large range of buts that follow. The newborns indeed get their initial "seeding" by birth, vaginally preferred and from the surface of the mother's body, and everyone and everything else in the surroundings. This is facilitated by two main factors: ...

In most isolation cases, the actual order isn't going to matter, since the typical isolation area that you would be allowed to enter isn't for the patient's benefit, but other people, so that they don't catch what the patient has. In this case, it doesn't matter which order you put it on. (Especially since they are being stored in an area where anyone ...

As a rule of thumb: anywhere that blood is coming out, you should be assuming that pathogens can be transferred in. In this situation I would smear with antibiotic ointment and wrap with sterile gauze every day (and after every shower) until the cracking-and-bleeding-with-motion stops.

One big problem here is that it's difficult to do double blind studies. One is then forced to use more theoretical arguments, but because medical science is not a hard science like physics, such arguments are not very reliable. The best we can then do is argue from biological plausibility, in this case we should take serious the fact that Homo Sapiens ...

A better comparison than "beard vs toilet" may be "face with beard vs face without beard." This is actually a reasonable concern in the context of healthcare, where healthcare staff can be a vector for disease and where vulnerable people are numerous. If facial hair is a reservoir for disease, it might be reasonable to recommend that healthcare staff remain ...

Much like you probably won't catch a cold every time someone sneezes on you, you also most likely won't get an eye infection every time you neglect contact lens hygiene. We all did it at some point, I'm sure. However... just because you can't see the wildlife on your contacts and hands, doesn't mean it's not there. It is. Little buggers like this one https:/...

I'm not a dentist, and I would look forward to reading other answers (I believe this topic is misunderstood and there is a lack of guidance generally), but these are my top tips: Don't brush straight after eating Your mouth becomes acidic after eating, and this can last for 60 minutes or so. So brushing immediately after eating is a bad idea, no matter ...

I am not aware of any evidence based research looking at the efficacy of at home ear wax removal. In general the goal is not to make your ear canals 100% free of wax at the microscopic level. Rather, the goal is remove blockages and NOT damage the ear canal. The American Academy of Otolaryngolgoy recommends: Most cases of ear wax blockage respond to home ...

Adverse Effects: A study [See Reference] analyzed the literature and did interviews with medical staff and found that the most common risk for laser hair removal is burns and changes in pigmentation. Lesser common complications include increased sweating, rash, post-op pain. Benefits: From what I've read [See Reference], the main benefit is cosmetic ...

A similar question is answered here: https://medicalsciences.stackexchange.com/a/17052/8728 but isn't really a duplicate. This has been studied, not in the context of health to the individual with the beard, but the related issue of whether wearing a beard presents a danger to others in a health care setting. Quoted from the earlier answer: Wakeam, et al. ...

The Aloe Vera is just to help moisturize the skin and is being used when glycerine can't be bought. Essential oils are a waste of time, and you need to add a water based substance to moisturize the skin. You need ethanol or isopropylalcohol as the basis of your sanitizer so that the final concentration is over 60%. https://youtu.be/WVvtF5uOX3Q

I had never heard of these things and never had them. I had to find out what they are and came across an article in Volume 21 - Issue 7 - July 2013 edition of The Dermatologist. The article says that An omphalolith – also referred to as an omphalith, omphalokeratolith or umbolith – is a keratin and sebum containing stone-like mass found in the umbilicus....

The correct use of dental floss is to use a new portion of the floss for every site. The easiest way to achieve it is through the loop or circle technique, using a new part of the loop every time. Here is a video Also, always use the floss before the toothbrush. If you use after, you will remove toothpaste (fluoride) deposited in the surface of the teeth.

There is no official medical advice on this matter, taking regular showers doesn't yield any known health benefits. Except for certain specialized professions e.g. in the medical field where you need to be sterile, you don't need to take showers except possibly for social reasons. Not taking showers, however, may yield health benefits. While not proven, ...

I agree with the comments in that article. It's rubbish. Does the NHS toss their bedding every few years?? To get rid of dust mites Wash bedding weekly. Wash all sheets, blankets, pillowcases and bedcovers in hot water that is at least 130 F (54.4 C) to kill dust mites and remove allergens. If bedding can't be washed hot, put the items in the dryer for ...

The evidence is inconclusive linking talcum powder to cancer. However, most doctors say there is no reason for you to use it, at all, ever, on any part of you. If you want to absorb perspiration, use clothing. For example, choose soft absorbent cotton underwear over shiny synthetic fabrics. Choose larger underwear that contacts more skin over "thong" or "...

Since you approach this from a mathematical point of view, you should consider reading this first. Von Neumann's theory on universal constructors captured the essentials of biochemistry long before the field of biochemistry came into existence, therefore the right approach in biology and medicine is to frame things in terms of robust machines that are going ...

There have been suspicions for a long time that meat processing plants are just plain unhealthy due to poor hygiene as well as likely aerosolizing animal viruses which are then inhaled by meat processing workers. This suggests that these places are unable to protect workers from air borne viruses Results: An excess of deaths from cancers of the base of the ...

TLDR: They're both equally effective. Technically, liquid soap is "cleaner" than bar soap unless the soap container is usually refilled. In more detail: From my understanding, any soap is effective at destroying viruses because it literally shreds apart the coating of the virus, obliterating it in the process. This is due to the nature of the soap being ...

The EPA has a list of products known to be effective against COVID-19. I can't tell you if your Lysol cleaner is one of them -- the list includes 14 different products sold under the Lysol brand, using five different active ingredients. Any cleaning product should have instructions on how to use it safely. As long as you follow those instructions, both ...

There's no quick fixes. The deeper you dug yourself in the pit, the taller and heavier the ladder you're gonna need to get yourself out. In general, there are a few rules to start with that should work for everyone. (Unless you're allergic to any of these items). Start counting calories. Avoid wheat, gluten, dairy. Eat as much as you can fresh home made ...
