Your Circadian Rhythm: What It Is And Why It Matters




If you’ve ever read anything about how using your cell phone can keep you from getting a good night’s sleep or wondered why you get jet lagged when you travel, then you’ve spent at least a little time thinking about circadian rhythms. But what exactly are circadian rhythms, and why are they so important? It’s a big question with a lot to unpack.

Your Body’s Clock

A common way that scientists and writers describe your circadian rhythms is as your body’s internal or biological clock, and this is a good, basic description. Circadian rhythms consist of the many different bodily patterns that are tied to a 24-hour daily cycle

These are physical, mental, and even behavioral, and different organ systems have their own unique expressions of these cycles. These shifts, which are largely regulated by exposure to light, especially sunlight, are most notable to the individual as hunger signals and digestion, body temperature, and alertness or fatigue.

Circadian Rhythm Disruptions

Another important factor everyone should understand about circadian rhythms is that their disruption by outside forces can lead to serious health problems. Now, a few nights of fatigue due to jet lag aren’t serious, of course, but in the long-term, dysregulation can lead to serious illnesses. And conversely, disruptions in circadian rhythms can be a sign of an underlying disorder.

As the most outwardly obvious sign of your circadian rhythms daily progression, sleep may be the most widely researched of the daily biological cycles. For example, researchers have looked carefully at sleep apnea as a cause of serious health problems

Sleep apnea can be obstructive – meaning it’s caused by a physical blockage – or central – meaning the brain doesn’t send the signal to breathe during sleep; but in either case, it can prevent people from experiencing restful sleep, leading to significant health problems, including daytime sleepiness, problems with appetite regulation, and even an increased risk of heart disease and obesity.

Circadian Rhythms And Neurodegeneration

One of the most significant recent discoveries of note regarding circadian rhythms is the link between circadian rhythm dysfunction and neurodegenerative conditions like Alzheimer’s disease. In a study supported by the Brain Research Foundation, Dr. Ravi Allada explored the function of the circadian clock gene in fruit fly models, specifically examining its neuroprotective role. When there is a mutation in this gene, his lab concluded, the body is less able to protect itself against neurodegeneration.

Circadian Rhythms And Cancer

Another emerging area of research related to circadian rhythms is in regard to cancer risk. When the body’s normal rhythms, which include those involved in immune system function, are no longer working properly, it’s more likely that normal cellular repair systems will fail. This can lead to dangerous mutations; the body may also be less able to naturally kill cancer cells when there is a circadian rhythm disorder present.

There are many different illnesses directly and indirectly linked to circadian rhythm disorders, and work addressing these issues is still in the early stages. What has become clear, however, is that the more we know about our vital internal rhythms and how to maintain them, the better equipped we are to protect our overall health.

Getting to the Root of It! Lebanese Cosmetic Dentist Dr. Mohammad Waizani Explains Root Canal Treatments




Did you know that more than 15 million teeth are treated and saved every year? One of the most common treatments received are root canal treatments. At Dr. Mohammad Waizani’s clinic in Beirut, he specializes in making sure anyone who comes in with a root canal, leaves with a bright smile! 

A root canal treatment is a dental procedure in which the soft center of the tooth called a ‘pulp’ is removed. The pulp is made out of blood vessels, connective tissues, and nerves. In these cases, the pulp is infected after being exposed to bacteria that causes a lot of pain. The crown of the tooth is usually still intact despite the pulp being dead. 

Root canals can be caused by several reasons such as a chip or cracked tooth, deep decay due to cavities that are left untreated, an injury to the tooth, and multiple procedures on the same tooth. 

Some of the signs of root canal infections include the following:

  • Constant toothache 
  • Heat sensation and swelling of gums
  • Sensitivity to heat and cold 
  • Swollen jaw
  • Discoloration of teeth
  • Pain with applied pressure 

Dr. Waizani explains how this surgical procedure works to remove the pulp and ensure the tooth doesn’t get infected. He starts by applying anesthetics to the gum and around the infected tooth. Next, the pulp is removed through a small opening at the top of the tooth. After the procedure is done, his patients’ recovery includes antibiotics to ensure that that infection does not flare up post-procedure. This is followed by a temporary filling. 

If you are experiencing any of the symptoms mentioned, there is no need to panic. Contact Dr. Waizani to schedule your appointment!
