Teeth Grinding and Jaw Clenching: The Gym Habits

Published

Gym Habits

Exercising and going to the gym involves preparation. There’s time and effort dedicated to warming up, preparing it for a workout. There’s time and effort dedicated to recovery, preparing it for the next workout. It is all about preventing injury, ensuring that your body is okay and ready for optimal performance. The areas of your body which gym goers sometimes neglect in this cycle of warm up, workout, and recovery are their teeth and jaws. A bit of a left-field observation and a comment which many might raise their eyebrows at but it’s true. The teeth and jaw are often not even afterthoughts.

Teeth Grinding and Jaw Clenching

People who lift weights clench their jaws or grind their teeth. It’s often a reaction to the stress of the activity. When we lift heavy weights, we are often activating a lot of muscles. There are the more obvious ones we are using to actually lift – more often than not: triceps, biceps, quads, etc. There are the less obvious ones which we use to supplement the core action. Clenching our jaw and/or grinding our teeth – otherwise known as bruxism – fall into the latter category. Experts suggest that bruxism can increase strength and power to enable better performance on lifts and other activities. There’s a reason we do it. However, it can cause oral issues.

Dental Problems

Dentists around the world see the same issues when gym goers clench their jaw and grind their teeth. The load put on and expressed through them have typical effects.

Let’s begin with the jaw. When you clench your jaw you should notice it won’t be fully aligned. It’ll lean one way. This can cause an uneven wear in your teeth. However, there are other issues more directly related to the jaw. Arthritis can occur due to strain and bone degradation or TMJ disorder can develop, also known as TMD. This disorder, according to a leading Calgary dental clinic, can cause issues like dizziness, which will further affect sporting performance. Nerve damage could also be a problem, whereby nerves in your jaw become inflamed and damage which can even extend to causing some neck pain.

Teeth face similar trauma. The pressure on your teeth can result in chips and cracks.  Robert Herbst, a world powerlifting champion, claimed one of his teeth exploded in a world championship final, which resulted in him needing bone grafts and an implant. There are “smaller” issues which can arise, like little holes in your teeth which can later, without treatment, cause cavities. In other cases, teeth simply reduce in size as they wear away.

 

Treatment

There’s two key solutions. Number one is self-awareness. Number two is a mouth guard.

Number one simply involves you lifting in front of a mirror and noticing yourself. If you begin to clench and grind, you stop. It’s a different kind of training. Breathing through your nose is also a helpful solution to include in this new habit.

A mouth guard acts as a barrier between your teeth, minimising the direct contact they have. Not only this but you’ll be able to find ones which helpfully align with your jaw, meaning that you will no longer be kicking out to one side. You could think of a mouthguard in the same way you think of belts and knee sleeves, another piece of hardware which helps to protect your body.

Canada allows Pfizer COVID-19 vaccine for children aged 12-15

(Corrects headline and lead to make clear that Canada was not the first nation as stated by Canadian officials, adds context from Pfizer in fourth paragraph)

By David Ljunggren

OTTAWA (Reuters) –Canada is authorizing the use of Pfizer Inc’s COVID-19 vaccine for use in children aged 12 to 15, the first doses to be allowed in the country for people that young, the federal health ministry said on Wednesday.

Supriya Sharma, a senior adviser at the Canadian federal health ministry, said the Pfizer vaccine, produced with German partner BioNTech SE, was safe and effective in the younger age group.

“We are starting to see the light at the end of the tunnel,” she told reporters.

Sharma and a health ministry spokesman said Canada was the first country to grant such an approval, but a Canadian representative for Pfizer later said Algeria permitted use of the vaccine for this age group in April. The Canadian health ministry said it had no information about the discrepancy.

The U.S. Food and Drug Administration is expected to take a similar step “very soon,” U.S. health officials said.

Separately, authorities reported the third death of a Canadian from a rare blood clot condition after receiving AstraZeneca PLC’s’s COVID-19 vaccine. The man, who was in his sixties, lived in the Atlantic province of New Brunswick.

Jennifer Russell, the chief medical officer of health in New Brunswick, said the province would continue using the AstraZeneca vaccine. Alberta reported a death from clotting on Tuesday and Quebec announced one on April 27.

“There will be rare cases where thrombosis will occur. However, the risks remain minimal compared to the risks, complications and potential consequences of COVID-19,” Russell told reporters.

Canada‘s federal government has bought tens of millions of doses of vaccines but critics complain the pace of inoculation is lagging due to bottlenecks in the 10 provinces, which are responsible for administering the doses.

Alberta will become the first province to offer COVID-19 vaccines to everyone aged 12 and over from May 10, Premier Jason Kenney said on Wednesday, a day after he introduced tighter public health measures to combat a third wave of the pandemic.

Alberta, home to Canada‘s oil patch, has the highest rate per capita of COVID-19 in the country, with nearly 24,000 active cases and 150 people in intensive care.

Around 20% of the 1,249,950 cases of COVID-19 in Canada have been reported in people under the age of 19. Canada has recorded 24,396 deaths.

Younger people filling up COVID-19 intensive care

Published

By Anthony Boadle

BRASILIA (Reuters) –COVID-19 infections continue to spread fast across the Americas as a result of relaxed prevention measures and intensive care units are filling up with younger people, the director of the Pan American Health Organization (PAHO) said on Wednesday.

In Brazil, mortality rates have doubled among those younger than 39, quadrupled among those in their 40s and tripled for those in their 50s since December, Carissa Etienne said.

Hospitalization rates among those under 39 years have increased by more than 70% in Chile and in some areas of the United States more people in their 20s are now being hospitalized for COVID-19 than people in their 70s.

“Despite all we learned about this virus in a year, our control efforts are not as strict, and prevention is not as efficient,” Etienne said in a virtual briefing from Washington.

“We are seeing what happens when these measures are relaxed: COVID spreads, cases mount, our health systems become overwhelmed and people die,” she said.

Canada continues to report significant jumps in infections in highly populated provinces such as Ontario as well as in less populated territories of the North and Yukon, home to remote and indigenous communities, according to PAHO.

Puerto Rico and Cuba remain significant drivers of COVID-19 cases in the Caribbean, which is facing a new surge of the virus, PAHO directors said.

Cases are rapidly accelerating in the Guyanas and across Argentina and Colombia, where weekly case counts are five times higher today than they were this time last year and hospitals are reaching capacity in large Colombian cities.

In Central America, Guatemala is seeing significant spikes in cases and Costa Rica is reporting record-high infections.

While vaccines are being rolled out as fast as possible, they are not a short-term solution because they are in short supply, said Etienne, the World Health Organization’s regional director.

Alberta confirms first death linked to AstraZeneca vaccine

Published

 on

Reuters) -The province of Alberta reported its first death of a patient from a rare blood clot condition after receiving the AstraZeneca COVID-19 vaccine, its chief medical officer said.

Canada has reported at least five cases of blood clots following immunization with the vaccine, but public health officials maintain the benefits of the AstraZeneca shot outweigh the potential risks.

The Alberta case, of a woman in her 50s, marks the second case of blood clots, and the only death after more than 253,000 doses of AstraZeneca were administered in the province, Alberta’s chief medical officer of health Dr. Deena Hinshaw said in a statement on Tuesday.

“While any death is tragic, it is important to remember that the risks of dying or suffering other severe outcomes from COVID-19 remain far greater than the risk following AstraZeneca vaccine,” Hinshaw said.

AstraZeneca did not immediately respond to Reuters’ request for a comment.

Canada has had 1,243,242 confirmed coronavirus cases and 24,342 deaths, according to a Reuters tally

Last month, the province of Quebec reported Canada’s first death of a patient after receiving the AstraZeneca COVID-19 vaccine.

AstraZeneca, working with the vaccine’s inventor Oxford University, was one of the leaders in the global race to develop a COVID-19 vaccine. Its cheap and easily transportable shot was hailed as a milestone in the fight against the crisis, but has since faced a series of setbacks.

The rare complication, which some regulators including Health Canada are calling Vaccine-Induced Prothrombotic Immune Thrombocytopenia, involves blood clots accompanied by a low count of platelets, cells in the blood that help it to clot.

Dozens of countries paused the use of the AstraZeneca vaccine in March after reports of rare, but serious, blood clots. Several of them have now resumed use either fully or with restricions after health regulators said the benefits of the shot outweigh any risks.
