Blue light: are LEDs dangerous for the eyes?

We talk more and more about the blue light emitted by some LEDs. Generally, in a somewhat negative way. Moreover, that is once again the case today. Researchers tell us how it damages our retina.

Remember that to see; we need photoreceptor cells in full shape. Also, to keep them in shape and to correctly perceive the light that reaches our eyes, they need a supply of molecules called retinal (C20H28O).

Blue and retinal light

However, according to American researchers, it is these same molecules that, exposed to blue light, end up blind us. They trigger reactions that produce killer molecules of photoreceptor cells. So once dead, the photoreceptor cells, unfortunately, do not regenerate.

Today, researchers advise us to protect our eyes by equipping ourselves with glasses capable of filtering blue light. Or not to use smartphones or tablets in the dark. Until a solution is found to block the toxic chemical reaction, they’ve uncovered.

Are LEDs dangerous for the eyes?

A study by Inserm raises the question of the dangers of LED bulbs for vision. In rats, some of the LED wavelengths are toxic to the retina in a mechanism that may promote age-related macular degeneration (AMD).

However, in the absence of pupil dilation, albino rats exposed to long-term LED light (continuously for a week or a month) also show retinal degeneration. So even non-albino rats, known to be protected from photo-induced degeneration, show signs of oxidative stress in their retinas.

Blue LED light is toxic to the retina

Behind the phototoxicity of LED bulbs, a culprit: blue light. Each light source – LED, fluorescent tubes or compact fluorescent bulbs – combines different colors in varying proportions. Also, the potential toxicity of each of them on the retina depends on both the intensity of the light and the wavelengths that compose it.

Although it is probable that the observations made in rats are not transposable as they are in humans, the data from this study are questionable. As a precautionary principle, these data call for the next generation of domestic light bulbs, in which we would reduce the proportion of blue light.

Beware of LED lighting

Some diode lighting lamps, or LEDs, would pose a risk to the eyes, especially children.
Light-emitting diodes (LEDs) are increasingly present on the spokes. Designated as ideal due to their low consumption, they multiply in homes or workplaces and flourish in car headlights. However, their light differs quite significantly from other types of lighting, and the usual standards do not suit them.

Its conclusions published in a report cast a shadow on this contemporary lighting, which would not be without risk. The study: wavelength and luminance note two main effects. Diode lights emit a significant proportion of blue light, i.e., short wavelengths.

Cannabis Smokers you should read this !

As there are fewer prejudices, different methods are becoming more and more accessible to the general population.

Smoking cannabis is an instant natural remedy for generations thanks to its ease of use. Now that it is allowed in more and more states and the practical side is a less important factor, it is time to weigh the pros and cons.

So what do the experts think?

With regard to its anti-tumor properties, the prevention of melanoma and the eradication of epilepsy problems and the underlying causes, cannabis oil rich in CDB is the most effective method.

However, if your illness includes chronic pain, inflammation, anxiety, loss of appetite and headaches, you should know this:
Many doctors consider vaporizers as the ideal method to consume cannabis. In fact, in Israel, where medical cannabis is legal, sprays can be found in hospitals and retirement homes. Volcano Medical Spray is a medical device also approved in Canada and the EU.

If you smoke cannabis beware of your lung’s health

The effect of vaporization on the lungs is perhaps the best argument for using a vaporizer.

use of a plant vaporizerDoctors have long been reluctant to use cannabis as a medication because of the effects of smoke combustion. Although cannabis smoking has not been proven to cause lung cancer, cannabis burning produces several known carcinogens, which can irritate the lungs and cause chronic bronchitis.

The vaporizers were primarily designed to overcome this problem. By heating cannabis at a temperature below combustion, the apparatus produces an inhalable vapor which always contains the active ingredients of cannabis (cannabinoids), but without the harmful sub-products.

Cannabis vapor removes about 95% of the smoke that is inhaled. In addition, it has been reported that steam increases the yield of anti-inflammatory terpenoids that protect the lungs from irritation.

Research also indicates that spraying can reverse the respiratory symptoms caused by traditional cannabis use.

Most cannabis lovers smoke the product. It is the simplest, the fastest way to get the benefit and for the most enjoyable. But also the least healthy especially in if your goal is to fumer de l’herbe sans tabac !

It is the simplest, the fastest way to get the benefit and for the most enjoyable. But also the least healthy especially in case of intensive use. And yes, inhaling a smoke is always harmful to the respiratory system and that of cannabis is no exception. Especially since it is usually mixed with the hard drug tobacco. A pure herb joint yields three times more tar than a cigarette and five times more carbon monoxide.

Moreover, the smoke of the joint is of higher temperature and often inhaled more intensely and for longer, which is useless, a simple passage in the lungs being equally effective. With the development of the medical use of cannabis appeared a whole bunch of new machines designed to smoke while preserving its lungs.


Natural Medicine and Its Multiple Benefits

Too many people these days are in medicine for things that are caused by poor nutrition. A healthy diet not only keeps your weight under control, it also prevents against some serious diseases, such as cancer and diabetes.

All of the preservatives in packaged foods have the tendency to cause disease. Our bodies were designed to digest the food that is grown from the earth, not the “food” that is made in factories around the world.

For every disease, there is a cure somewhere on this earth.

Even the healthiest person can get sick or injured. For a lot of people this means going to the doctor. While doctors are indeed needed in this world for serious things such as setting bones and surgeries, they are not always needed for something like the flu, bronchitis, a UTI, or any of the numerous things they see thousands of people a day for.

Some natural medicines that are too often overlooked are baking soda, lemon juice, and apple cider vinegar. They can help cure sickness and disease as well as contribute to preventing it when taken a few times a week. A good way to make sure you are getting the benefits of each is to take one dose daily, alternating, first baking soda, then lemon juice, then apple cider vinegar.

Use one cup of water, and mix in either one teaspoon baking soda, or two tablespoons lemon juice or apple cider vinegar. Use aluminum-free baking soda and 100 percent organic, not-from-concentrate, no sugar added lemon juice. Apple cider vinegar should be organic and unfiltered. These simple and natural medicines help prevent and treat everything from UTIs to cancer to obesity, and are much lighter on your wallet than prescription drugs.

Merits of Thai Massage Over Other Massages

Thai massage has one large benefit as compared to regular massages because it also massages the therapist in the process. Given that it is traditionally performed on a floor mat, the therapist can use many body components like hands, forearms, elbows, knees, and feet. This makes Thai massage more therapist friendly by allowing the therapist take pressure off their arms.

It is a well-known practice to do half of a Thai massage session with other body components besides arms. Many regular massage therapists mostly carry out massages with their hands which include the danger of wounding thumb or wrist joints that can lead to carpal tunnel syndrome.

coffret bienvenue bien etreIn Thailand, there is a sizeable amount of female Thai massage therapists who often work mostly with western customers. And a recent study finds that patients from the West find the use of the elbow, feet and knees to be too intense. Additionally, operating on a ground mat lets in for better ergonomics than working on a desk wherein you need to lean over to reach the patron’s frame. On the other hand carrying this out on a floor mat gives you a proper hold over the patient’s frame and allows you use your body weight a lot more efficiently. This reduces pressure on the muscle and is therapist friendly too.

There have been reports on therapists who complained about being no longer able to do western style body massages on a desk. However, they could do Thai massage due to the above-stated benefits. Regularly people want to know what the difference between Thai massage and “average massage.” is the simple answer is a regular western massage is performed at a massage desk.
Thai massage isn’t like the regular massages out there. Traditional massages usually entail lying in one position and getting alloyed for an hour or so — an admirable acquaintance nonetheless.

An Introduction to Laser Hair Removal

When a person is not happy with the amount of body hair that they have, they can get a laser hair removal treatment. The process will help reduce the amount of body hair a person has with the user of lasers. This process is more efficient than shaving, tweezing, or even waxing according to experts.

A common cosmetic procedure.

Sugar paste used to remove hair

Removing hair with lasers is a common cosmetic procedure. Highly concentrated laser beams are shown onto the hair follicles under the skin. The pigments can absorb this light and destroy hair from the root.

This laser treatment can help remove unwanted hair from the face, legs, underarms, bikini area, as well as other areas. The lasers can remove even dark and coarse hair and will not damage the skin around them.

Modern technology offering comfort.

The laser technology used is able to remove any hair follicles at the same time. It will remove hair in an area the size of a quarter every second that it is used. Before having this treatment, a person should not remove their hair for six weeks. This will allow the lasers to get the hair at the root.

During this laser treatment, a specific process is used. During this process, the outer layers of the skin may be covered with a gel-like substance for protection. A laser will then be used over the area that is being treated to remove the hair. After the laser is used anti-inflammatory cream will be applied to the skin. A person will need to have another laser hair removal treatment in six weeks to prevent the hair from growing back. A person can expect to have a feeling of sunburn a couple of days after having this procedure.

the good old shaver
No need to use the good old shavers…

Laser hair removal will help a person to get finally rid of unwanted hair. This method will prevent the hair from growing back as quickly and over time will prevent body hair from growing back at all.

What Is Implant Dentistry And Why Is It Great?

Implant dentistry is the specialization of dentistry that deals with the replacement of teeth in a very successfully way. This specialized form of dentistry is all about dental implants. Dental implants are the very thing that has managed to revolutionize dentistry and permit a dental practitioner in East Perth to mount replacement teeth straight into a metal post or frame that is designed to be strong and to last in a description.

dental implant processA dental implant is a unique titanium post. This is because it is every inch like a tooth root and it is surgically positioned into one’s jawbone, which is beneath the gum-line, and which does allow a dentist to put in replacement teeth for natural teeth that are missing or whatever else. A bridge can also be put into the area, as well, also. An implant is something that cannot become loose like a denture can. What is great about dental implants is everything. They are far more than just replacement teeth for missing teeth, teeth that have been damaged, or whatever else in connection with teeth that do need replacement for whatever reason. These dental implants are the thing that can significantly benefit oral health too.

Implant dentistry has greatly influenced the world of dentistry in a major way for numerous reasons. However, one of the most important of all reasons is something, which does make it stand out as being one of a kind in delivery. Dental implants do make oral health a whole lot better and not just for superb smile quality either. These dental implants are dental devices that don’t have to be anchored to other teeth means they are less of a painful process (remember you can still ask for dental sedation if needed). Bridges do need to be anchored. However, dental implants do not, and this is where the big oral advantage does clearly come into play.

xray scan of a jawThe American Dental Association does consider two forms of dental implants to be the safest, as well as, the most active forms of implant dentistry to be used for patients. These two types of dental implants are no other than Endosteal implants and Subperiosteal implants. Endosteal implants are those that are placed surgically right into the jawbone itself. Once the gum tissue has healed after the dental implant has been inserted, the next step is this, and that is to connect a post up to the original implant. The final step is, to then put in a plastic type of tooth or teeth, and this is done by attaching the tooth or teeth individually to the post itself. It is also something that can be grouped onto a bridge or denture.

Subperiosteal implants are those that are made from a metal frame. This metal frame is fitted directly onto the jawbone. This jawbone is usually located just right below the gum tissue. When the gums start to heal, the metal frame is something, which does become fixed into the jawbone. There are posts, which are connected to the metal frame, and these posts are seen protruding from the gums themselves. In the very same manner, as is, endosteal implants. Subperiosteal implants do contain artificial teeth. These false teeth are mounted onto the metal frame via posts.

Cosmetic Dentistry

smileIf you are unhappy with the way that your teeth look, it can really affect your confidence. You may feel as you don’t want to do anything that involves opening your mouth in public, such as smiling, or even talking to other people. A cosmetic dentist offers a wide range of services that can help improve the appearance of your teeth, and help you get some of your confidence back. They specialize in these types of procedures and therefore can be a better choice to carry them out than your regular dentist.

bracesMany people have teeth that are slightly uneven. In the past, this problem has been overcome with the use of braces. These braces were often unsightly, and some adults would feel apprehensive about wearing them as they are considered to be something that a child would wear. The braces that are used by cosmetic dentists are now barely even noticeable and are much more comfortable to wear.

Another popular cosmetic dentistry procedure is the whitening of teeth. This helps to restore teeth that have become discolored and stained back to their natural whiteness. A form of bleach is used to whiten teeth, but this has been formulated so that it is perfectly safe to be applied to your teeth. The teeth whitening process is usually carried out over a number of sessions, but you will be able to notice a difference in the color of your teeth almost straight away.

dental mirrorsWhen you have decided that you want to have a procedure carried out, then you will need to find a reputable cosmetic dentist. If you know someone who has recently had some work carried out, then you may want to ask them for a recommendation. When you have chosen a dentist, then it is always a good idea to ask to see testimonials from previous customers and examples of their work. You should also check their qualifications and that they are fully insured in case of the unlikely event that something should go wrong.

How To Prepare For Wisdom Tooth Extraction

Wisdom tooth extraction is a common type of oral surgery that is performed by dentists, oral surgeons, or maxillofacial surgeons. You may have seen videos or heard stories of the aftermath that individuals have faced after their wisdom tooth surgery. Whether it is funny reactions from the anaesthetics or having to rdentistely on a liquid diet afterwards, wisdom teeth surgery and the aftermath may make you feel nervous. As many individuals are given anaesthetics during their extraction, so they are either numbed or asleep during the procedure, the surgery itself can be a pretty easy experience. The aftermath is what people need to be educated on in order to have the best experience as possible. Below, you will find tips on how to prepare for and recover from wisdom tooth extraction surgery.

  1. Buy Groceries Before The Surgery


After wisdom tooth surgery, you will be required to eat a liquid diet; this can include soup, jelly, pudding, shakes, applesauce, yogurt, and more. It is preferred that you eat food that does not require you to chew; you will have stitches in your mouth and solid foods may cause them to tear. Not only will you have to eat a liquid diet that you don’t have to chew, but you will also need to ensure the food you buy is not served at very hot or cold temperatures.

  1. Get Someone to Drive You To Your Surgery

Since anaesthetics are used for wisdom tooth surgeries, it is important to have someone drive you to and from your appointment. The anaesthetics will leave you feeling groggy and could impair your driving. Choose a person you can trust to take you to and from your appointment. They should know you well enough to speak on your behalf since you will be required to go to a pharmacy and pick up a pain medication prescription. Since you cannot talk, it is important that you choose someone that can provide all the information the pharmacy will need to know.


  1. Take Care of Your Mouth


Once your wisdom teeth are removed, you will be required to have gauze in your mouth to soak up any blood or saliva as well as help the clotting process. The gauze should be kept in your motoothbrushuth for at least 30 minutes after your surgery; do not change the gauze. Once the gauze is removed, there is a variety of steps that need to be taken in order to take care of the surgery site. These include avoiding continuously spitting out blood as well as rinsing your mouth with salt water. When rinsing your mouth with salt water, combine 1 teaspoon of salt and 8 ounces of warm water. Do not gurgle the water; let the water sit in your mouth as gurgling could cause a blood clot in the surgical site.

There is a variety of steps that can be taken in order to make your wisdom tooth surgery recovery the best experience as possible. In order to fully prepare for your surgery, as well as the aftermath of it, follow the above steps. Most dentists and oral surgeons who complete these surgeries will provide you with a booklet of information with additional information about the surgery and recover process to ensure you are as educated as possible about it.

Balance Is The Key

With people living longer these days, making sure you’re healthy during that extended lifespan is more important than ever before. And you don’t have to be a rocket scientist or a nutritionist to know that some things are good to do, and somethings are to be avoided at all costs.

Eating right is the foundation of good health.

Nowhere else in life does the old adage, “Everything in moderation” applies more than with what we eat. Sure, experts will tell you that salty or fatty foods are bad for you, but those are only bad if eaten every meal of the day. Fruits and veggies are good for you, but the body also needs natural protein as part of a balanced diet. Grains are good as well, but there are good grains (oats and rice) and bad grains (wheat – not the worst thing on the planet, but should be limited in your diet). The basic watchword here is balance. A little bit of everything you like, with an occasional splurge on a “cheat” food – something that is not too good for you, but satisfies your need to be bad – is the best way to go.chocolates
Water is the key to a healthy life style, and while drinking water alone is a good start, don’t assume that all water is the same. Different sources of water (municipal, well water, rivers or lakes) all have different levels of quality, and all have some measure of impurities that can be potentially harmful if taken in large quantities. Make sure you have a good filtration system in your home or office to get rid of those impurities and chemicals. There are trade-offs to every system out there. Faster systems provide better flow, but don’t catch everything needed to be filtered out. Slower systems filter out most every harmful element but provide that water in a slow trickle. But remember, while water is important, you don’t (and shouldn’t) drink gallons of it every day. Too much water can flush out valuable minerals that your body needs to stay healthy. Also, if you don’t filter water throughout your whole house, consider at least filtering the water you shower or bathe with, as your skin can absorb harmful chemicals from water almost as easily as drinking them.


Organic should not be a trend, it should be your way of life.

Too much of our food has been genetically modified, and while there are benefits to some of the modifications, like extending shelf life and providing better pest control, the benefits of buying something that doesn’t spoil as fast are outweighed by the increases in other harmful chemicals used in the growing process. Organic costs more, and you’ll have to shop more often because you’re buying less quantity due to the product being less resistant to spoilage, but organic tastes better and is better for you. Remember that what we put into our bodies is going to determine how healthy we are today and in the future, and could be the foundation for an active and healthy lifestyle as we grow older.
