Resting heart rate chart by age:

HEART RATE is a crucial indicator of how our hearts are working. So what should your resting heart rate be and how can you check it?

Our heart has a big role to play in the day-to-day functioning of our bodies, as it is responsible for pumping blood and oxygen. When looking after our cardiovascular health, it is important to pay attention to our heart rate. Resting heart rate is the number of times the heart beats each minute when someone isn't active. It is easy to work out what your resting heart rate is, so read on to find out more.

What should resting heart rate be?

Most adults have a resting heart rate between 60 and 100bpm, according to the NHS.

However, the fitter someone is, the lower their resting heart rate is likely to be.

The NHS website adds: "See a GP to get checked if you think your heart rate is continuously above 120bpm or below 40bpm, although it may simply be that this is normal for you."

Normal resting heart rates differ for children and are as follows, according to Medical News Today:

· Up to 1 month - 70 to 190 beats per minute (bpm)

· From 1 to 11 months - 80 to 160 bpm

· From 1 to 2 years - 80 to 130 bpm

· From 3 to 4 years - 80 to 120 bpm

· From 5 to 6 years - 75 to 115 bpm

· From 7 to 9 years - 70 to 110 bpm

· Over 10 years - 60 to 100 bpm



How can you check your resting heart rate?

Resting heart rate is measured by counting the number of times the heart beats while sitting still. To check your resting heart rate, you can use a heart rate monitor or alternatively check your pulse. To do this, the British Heart Foundation (BHF) explains you can put one of our hands out so you are looking at your palm. Place the pads of your first two fingers of the other hand on the inside of the wrist, at the base of the thumb, and press lightly.










If you can't feel your pulse, press slightly harder and check for about 30 seconds to see if it feels regular or not.

Count the number of beats after 60 seconds, or count the beats for six seconds and multiply by 10, to find out your resting heart rate in beats per minute (bpm).

The BHF explains that if your pulse feels irregular, check it for the full 60 seconds.

An irregular heart rhythm or pulse or any other concerns should be checked with a doctor, to check whether it is indicative of a health problem like arrhythmia.

What should your target heart rate be by age?

In general, maximum heart rate depends on age and one way to work it out is to take your age away from 220.

Target heart rate is usually between 50 and 70 percent of someone's maximum heart rate for moderate exercise intensity.

In general, the BHF says people should aim to exercise with their heart rate between these two figures.

But everyone's circumstances are different and for anyone with a heart condition it is important to check with a doctor before doing any new exercises.

Here is a chart of target heart rates based on age, as per the American Heart Association:

Age: 20 years
Target HR Zone 50-85%: 100-170 bpm
Average Maximum Heart Rate, 100%: 200 bpm

Age: 30 years
Target HR Zone 50-85%: 95-162 bpm
Average Maximum Heart Rate, 100%: 190 bpm

Age: 35 years
Target HR Zone 50-85%: 93-157 bpm
Average Maximum Heart Rate, 100%: 185 bpm

Age: 40 years
Target HR Zone 50-85%: 90-153 bpm
Average Maximum Heart Rate, 100%: 180 bpm

Age: 45 years
Target HR Zone 50-85%: 88-149 bpm
Average Maximum Heart Rate, 100%: 175 bpm

Average Maximum Heart Rate, 100%: 160 bpm

Age: 65 years
Target HR Zone 50-85%: 78-132 bpm
Average Maximum Heart Rate, 100%: 155 bpm

Age: 70 years
Target HR Zone 50-85%: 75-128 bpm
Average Maximum Heart Rate, 100%: 150 bpm

Blood pressure chart: What is a healthy range? 8 signs your blood pressure is too high

BLOOD PRESSURE measures the force that your heart uses to pump blood around the body, but can be dangerous if gets too high or drops too low. So, what is a healthy blood pressure range?

Blood pressure, when too high, is often related to unhealthy lifestyle habits like drinking too much alcohol, smoking cigarettes, eating unhealthy foods, being overweight and not doing enough physical exercise. When it’s left untreated, high blood pressure can seriously drive up your risk of developing numerous long-term health conditions, like coronary heart disease and kidney disease. Low blood pressure is much less common, and is sometimes brought on by medicinal side effects.

What is a healthy blood pressure range?

Blood pressure is the pressure of the blood within the human arteries and is produced primarily by the heart muscles contracting.

Blood pressure is measured using two recorded numbers.

The first looks at systolic pressure and is measured after the heart contracts at its highest level.

The second, called diastolic pressure, is measured before the heart contracts at its lowest, while blood pressure elevation is referred to as hypertension.

Blood pressure can be categorised into five different kinds in an effort to distinguish what’s high.

Normal blood pressure below 120/80 mm Hg is considered to be a healthy level all around.

Elevated blood pressure readings consistently range from 120 to 129 systolic and less than 80 mm Hg diastolic.

People with elevated blood pressure are at risk of developing high blood pressure unless adequate steps are taken to control it.










Hypertension stage one: At this stage of blood pressure elevation, readings consistently range from 130 to 139 systolic or 80 to 89 mm Hg diastolic.

Doctors at this point could prescribe blood pressure medications and some lifestyle changes to reduce the risk of heart disease and strokes.

Hypertension stage two: During this level, blood pressure readings range consistently from 140/90 mm Hg or higher.

When patients have reached this point of hypertension, medics are very likely to intervene with a combination of medicine and lifestyle changes.

Hypertensive crisis: This is the most critical point blood pressure can reach, and requires urgent medical attention as soon as possible.

When pressure reaches this level, it suddenly exceeds 180/120 mm Hg.

If you have any of the following symptoms, contact an ambulance immediately:

· Shortness of breath

· Chest pain

· Back pain

· Numbness and/or weakness

· Changes in vision

· Difficulty speaking

Eight signs your blood pressure is too high

Hypertension can be terrifying because many people who get it won’t experience any symptoms.

In some cases, it may take years or decades for the condition to reach levels high enough that symptoms become obvious.

Even then, it’s easy to attribute the symptoms to other health ailments, but acting for a symptom of high blood pressure can be fatal so be extra wary if you think you could be affected.

The best way to know if you have hypertension or your blood pressure is too high is to have regular readings, but signs to look out for include:

· Headaches

· Shortness of breath

· Nosebleeds

· Flushing

· Dizziness and nausea

· Chest pains

· Visual changes

· Bleeding in the urine

Booster shots may NOT be needed this autumn but the elderly and NHS will be first in line if they are, claims one of No10's top vaccine advisers 

Booster Covid vaccines may not be needed this autumn, one of the Government's top experts claimed today.

Professor Adam Finn, from the Joint Committee on Vaccination and Immunisation (JCVI) - which advises No10, insisted top-up jabs may well be required for the very elderly and NHS workers.

But he admitted there was still a 'high level of uncertainty' over whether they would be necessary for millions of other Brits.

Scientists had expected the protection given by vaccines to begin to wear off over time but they don't yet know how long immunity from Covid jabs lasts for.

Influenza vaccines are needed every winter because the virus is constantly evolving to beat the human immune system. 

Coronaviruses tend to mutate slower and academics have claimed they've yet to see any proof of waning immunity in vaccinated Britons.

Last month Matt Hancock announced at a Downing St press conference scientists were beginning trials of a third jab to check if it offers better protection.

Millions more vaccine doses than necessary have been bought by the Government and a giant order of 60million more Pfizer doses in April was earmarked for a top-up campaign in the autumn. 

==============================

British health chiefs could soon issue a warning that Pfizer and Moderna's Covid jabs are linked to heart issues in extremely rare cases, experts believe. 

Fears about the two jabs causing myocarditis have grown in recent weeks, following a string of cases in young adults and children in Israel and the US.

American regulators have already accepted there is a 'likely link' between the heart condition and the vaccines, and will add warnings about the potential complication on information sheets given to the public.

Israel's Health Ministry has said the Pfizer vaccine, the only jab it is using in its rollout, is the 'probable' cause in a tiny number of cases. 

Last week the Medicines and Healthcare products Regulatory Agency (MHRA), which polices the safety of drugs in the UK, said rates of myocarditis among vaccinated adults were 'similar or below' expected levels.

But last night, MailOnline can reveal the watchdog dropped all mention of how often the complication was occurring. Instead, it just updated its weekly summary to say cases were 'very rare' and 'typically mild'.

One cardiologist said he believed it the change in tone may signal that the body was going to accept a link between the two vaccines and myocarditis. 

Other experts warned it further complicated the debate about vaccinating children in Britain. 

============================================================

WHAT IS MYOCARDITIS? 

Myocarditis is an inflammation of the heart muscle. There are no specific causes of the condition but it is usually triggered by a virus.

Some of the most common infections which cause myocarditis, are those called adenovirus and Coxsackie B.

It can be caused by the common cold, hepatitis B and C, and herpes simplex virus. 

The most common symptoms of the condition include chest pain, a fever, a fast heartbeat, tiredness and shortness of breath.

If the inflammation damages the heart muscle or the fibres that conduct electrical pulses to the heart, complications can develop.

They can develop quickly, and include sudden loss of consciousness, an abnormally fast, slow or irregular heartbeat.

In very severe cases the condition is fatal, causing heart failure or sudden death. The inflammation enlarges the heart and creates scar tissue, forcing it to work harder and therefore making it weaker.

In most cases of viral myocarditis, the illness goes away and there are no complications. 

But in rare cases when inflammation is severe, there can be damage to the heart which needs monitoring and possibly a heart transplant.

Myocarditis can reoccur, but there is no known way to prevent this. The risk of recurrence is low, around 10 to 15 per cent, according to Myocarditis Foundation.

It is difficult to gauge the prevalence of myocarditis because there is no widely available test for it.

In 2010, approximately 400,000 people died of heart muscle disease - cardiomyopathy that includes myocarditis - worldwide.

Expert consensus opinion estimates that up to 40 per cent of dilated cardiomyopathy results from myocarditis, according to the National Organisation for Rare Disorders.

AstraZeneca & Pfizer's jabs some problems (quoted from https://www.dailymail.co.uk/news/article-9712333/

 

Four British men develop potentially deadly Guillain-Barré syndrome just days after having AstraZeneca's Covid jab

• Four men in Nottingham developed Guillain-Barré syndrome after a Covid jab
• Cases linked to AstraZeneca's vaccine but scientists have not identified cause
• Six cases of the syndrome were also identified in Australia and seven in India

Four British men have developed a potentially life-threatening condition just days after having AstraZeneca's Covid vaccine. 

The recipients developed Guillain-Barré syndrome, which can cause paralysis and leave patients in crippling pain. 

All four cases were spotted in the Nottingham area, where around 700,000 people have had the British firm's coronavirus jab. 

British health chiefs have yet to offer a public breakdown of how many cases of the syndrome have been spotted in vaccine recipients across the entire country. 

But a similar link has been spotted in both Australia and India, where AstraZeneca's vaccine is also being dished out. It is also a known rare side effect of flu and HPV jabs.

AstraZeneca's jab — which is given as a double-dose — has also been heavily linked to deadly blood clots in younger adults. 

For that reason, UK drug watchdogs have recommended under-40s, who face a tiny risk of falling seriously ill with Covid, get alternative jabs.

But data is now also emerging that shows Pfizer's jab — the other main option being administered in the UK — may cause heart inflammation. 

Cases of Guillain-Barre syndrome after AstraZeneca's vaccine were described in two separate studies in the journal Annals of Neurology.

The complication — normally triggered by an infection — usually occurs in around one in 100,000 people in the UK and US.

What is Guillain-Barre syndrome?

Guillain–Barré syndrome is a rare disorder in which the immune system goes into overdrive and the body attack its own nerves.

Common symptoms of the rare condition include weakness and tingling in the limbs. 

As patients' conditions worsen, this can lead to parts of the body — or in some cases the whole body — being paralysed.

The syndrome is rare, affecting about one in 100,000 annually in the UK and US.

Fewer than 20,000 cases are diagnosed per year in the US, according to the National Institute of Neurological Disorders and Stroke. 

Doctors say it is often triggered by a viral or bacterial illness, such as Campylobacter jejuni. 

There is no cure. Treatment focuses on restoring the nervous system.

It can be fatal if it involves the respiratory muscles. 

But doctors in India who also uncovered the link say it was occurring up to 10 times more than expected.

One of the articles published in the journal broke down the cases spotted in Nottingham, which all occurred within ten days of each other. 

Symptoms began 11 to 22 days after the first jab and all of the four men were aged between 20 and 57.

One had no relevant medical history. The three others others had ulcerative colitis, asthma and high blood pressure.

None had been infected with Covid. They were treated with antibodies and steroid pills.

Dr Christopher Allen, a clinical neuroscientist at Nottingham University, who wrote the article, admitted they cannot be certain the jab caused the neurological illness and it could have happened by chance.

But it demonstrates the need for 'robust post-vaccination surveillance,' he said. And he added vaccines currently deployed are 'very safe'.

Dr Allen added the reaction may be 'a cross-reactive immune response to the SARS-CoV-2 spike protein', causing the immune system to overreact and the body to attack its own nerves. 

Dr Allen said if the condition is caused by AstraZeneca's vaccine, it will be because spike proteins contained in the firm's viral vector technology.

Pfizer's and Moderna's MRNA vaccines do not contain the same spike proteins, so are unlikely to see similar links to the syndrome.

The second paper by neurologists at the Aster Medcity hospital in Kochi, Kerala, identified seven cases of severe Guillain-Barré syndrome.

They were struck down within a fortnight of receiving the first AstraZeneca vaccine.

Lead author Dr Boby Varkey Maramattom said rates of the condition were between 1.4 and 10-fold higher than would normally be expected. 

And the patients suffered 'unusually severe' facial weakness — one of the symptoms of the condition.

Four of the cases involved women aged 40 to 70 years — three of whom required mechanical ventilation.

Nerve damage around the face and head occurred in four patients — which happens in less than five per cent of Guillain-Barré syndrome cases.

Dr Maramattom said while the findings suggested the vaccine could be to blame a clear link had been proven and it is 'unlikely' the jabs had triggered the syndrome in all cases.

The benefits of vaccination also 'substantially outweigh the risk of this relatively rare outcome,' he said.

Covid itself is also linked to Guillain-Barré syndrome, with the virus believed to have triggered the condition in a man, 54, in New Jersey in April 2020.

Pulse النبض ما أعظم خلق الله

 

Think about it...
when you're sitting still and not breathing...what is the only thing in your body that's palpably moving?
 Every second, your body gives you a little sign to prove that it's still there.
A pulse.
It is billions of cells beating for billions of times in a lifetime, never pausing to rest.
Behind that beat is an unbelievably vast system whose one and only job is to make sure every cell in your body stays alive.
- The speed, the strength, the frequency, the rhythm...it tells us so much.
- A heart that thumps...blood that flows through thousands of miles of arteries and veins...
All so we can attempt the crazy feats that make humans...unique.
Human life depends on one substance above all others...Oxygen.
We can go about three weeks without food, three days without water.
But without oxygen, we wouldn't last three minutes.
But why? Well, if you think about it, each of us is just a huge pile of cells, somewhere around 37 trillion.
Blood cells, skin cells, brain cells. And every single one of those cells contains an engine that runs on oxygen.
Think of it like a fire that's always burning. Oxygen is the wood or coal.
And to keep the fire stoked, all we have to do is breathe in.
But getting a supply of oxygen is the easy part.
Once it's inside the body, all that fuel has to somehow find its way into those 37 trillion engines.
And that requires a system that never rests. (الله أكبر تبارك الله أحسن الخالقين)
- The cardiovascular and circulatory systems represent our major engine in our bodies.
Now, this is to make sure that all of our cells have oxygen going in, carbon dioxide leaving, plenty of nutrients, and essentially keeps us going.
- The body itself is pretty small, but the network of vessels is enormous.
The vessels themselves laid end-to-end would be about 100,000 miles long, which would encircle the globe probably four times.
- This vast network of pumps, valves, and tunnels delivers oxygen to cells in every corner of your body, without you ever having to think about it.
And what's more insane than that is we can train this system to work even more efficiently. Especially when oxygen is harder to come by.

Cost of Vaccines

What we know

The federal government is providing the vaccine free of charge to all people living in the United States, regardless of their immigration or health insurance status.

COVID-19 vaccination providers cannot:

• Charge you for the vaccine
• Charge you directly for any administration fees, copays, coinsurance, or the balance of the bill after appropriate reimbursement
• Deny vaccination to anyone who does not have health insurance coverage, is underinsured, or is out of network
• Charge an office visit or other fee to the recipient if the only service provided is a COVID-19 vaccination
• Require additional services in order for a person to receive a COVID-19 vaccine; however, additional healthcare services can be provided at the same time and billed as appropriate

COVID-19 vaccination providers can:

• Seek appropriate reimbursement from the recipient’s plan or program (for example, private health insurance, Medicare, Medicaid) for a vaccine administration fee
• Seek reimbursement for uninsured vaccine recipients from the Health Resources and Services Administration’s COVID-19 Uninsured Programexternal icon

Effectiveness الفاعلية

What we know

COVID-19 vaccines are effective at keeping you from getting COVID-19. After you are fully vaccinated, you can start doing some things you had stopped doing because of the pandemic.

Studies show that COVID-19 vaccines are effective at keeping you from getting COVID-19. Getting a COVID-19 vaccine will also help keep you from getting seriously ill even if you do get COVID-19. التطعيم (اللقاح) فعال يحميك من كوفيد 19 ويساعد على أن لا يكون المرض شديد إذا أصيبت ب كوفيد 19

COVID-19 vaccination is an important tool to bring you closer to enjoying the activities you have missed. Learn more about the benefits of getting vaccinated.

COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. It typically takes 2 weeks after vaccination for the body to build protection (immunity) against the virus that causes COVID-19. That means it is possible a person could still get COVID-19 before or just after vaccination and then get sick because the vaccine did not have enough time to provide protection.  People are considered fully vaccinated 2 weeks after their second dose of the Pfizer-BioNTech or Moderna COVID-19 Vaccine, or 2 weeks after the single-dose Johnson & Johnson’s Janssen COVID-19 Vaccine. التطعيمات(اللقاحات) تعلم نظامنا المناعي(فضل الله) كيف يتعرف ويتغلب على الفيرس المسبب لكوفيد 19 ويحتاج الجسم إلى أسبوعين بعد التطعيم (أخذ اللقاح) لإنتاج المضادات (هذا خلق الله) التي تساعد على التعرف ومقاومة المرض فيما بعد ولهذا من الممكن أن يصاب الشخص الذي تم تطعيمه سواء أثناء فترة التطعيم أو بعدها بالمرض ويمرض لأن التطعيم لم يستغرق الوقت الكافي لإنتاج الأجسام المضادة والأشخاص يعتبروا محصنين بعد أسبوعين من أخذ الجرعة الثانية من تطعيم Pfizer-BioNTech or Moderna 

أو بعد أسبوعين من تطعيم جرعة واحدة من  Johnson & Johnson’s Janssen  

You should keep using all the tools available to protect yourself and others until you are fully vaccinated. After you are fully vaccinated, you can start doing some things you had stopped doing because of the pandemic. 

What we are still learning

Scientists are still learning how well vaccines prevent you from spreading the virus. We’re also still learning how long COVID-19 vaccines protect people.

مازال العلماء يتعرفو كيفية جودة (اللقاح) التطعيم  في عدم أنتشار أو انتقال المرض من الشخص الذي تم تطعيمه كذلك ما الفترة التي يبقى (اللقاح) التطعيم فعال لمن حصلوا على التطعيمات

Although COVID-19 vaccines are effective at keeping you from getting sick, scientists are still learning how well vaccines prevent you from spreading the virus that causes COVID-19 to others, even if you do not have symptoms. Early data show that vaccines help keep people with no symptoms from spreading COVID-19, but we are learning more as more people get vaccinated.

We’re also still learning how long COVID-19 vaccines protect people.

For these reasons, people who have been fully vaccinated against COVID-19 should keep taking precautions until we know more, like wearing a mask in indoor public places, avoiding large indoor gatherings, and washing your hands often. Vaccinated people do not need to wear masks outside except in crowds.

لذا يجب على كل من أخذ التطعيمات أن يبقى على الأحتياطيات في لبس الماسك والتباعد وغيرها لأنه كما تم الإشارة سابقاً العلماء لم يتوصلو بعد إلى مدة صلاحية هذه (اللقاحات)التطعيمات وفاعليتها مع مرور الوقت(أشهر سنوات,,,,)

Safety

What we know

COVID-19 vaccines are safe and effective. Vaccines cannot give you COVID-19. You may have side effects after vaccination. These are normal, and should go away in a few days.

You may have side effects after vaccination, but these are normal من الطبيعي أن يشعر البعض بأعراض جانبية بعد أخذ (اللقاح) التطعيم

After COVID-19 vaccination, you may have some side effects. These are normal signs that your body is building protection. The side effects from COVID-19 vaccination, such as tiredness, headache, or chills, may affect your ability to do daily activities, but they should go away in a few days. Learn more about what to expect after getting vaccinated.

Population Immunity المناعة المجتمعية (بدل مناعة القطيع)

What we know

Population immunity means that enough people in a community are protected from getting a disease because they’ve already had the disease or because they’ve been vaccinated. المناعة المجتمعية هي أن يكون عدد كافي من الأشخاص في المجتمع تم حمايتهم بالتطعيم (أخذوا اللقاح) من المرض لأنهم بالفعل قد أصيبوا به( أو إنهم قد تم تطعيمهم ) 

Population immunity makes it hard for the disease to spread from person to person. It even protects those who cannot be vaccinated, like newborns or people who are allergic to the vaccine. The percentage of people who need to have protection to achieve population immunity varies by disease.

المناعة المجتمعة تجعل من الصعوبة أن ينتشر المرض من شخص لأخر كما أنها تحمي حتى الأشخاص الذين لم يمكن تطعيمهم مثل حديثي الولادة والأشخاص الذين يعانون من حساسية للتطعيم أو اللقاح) ونسبة الأشخاص الواجب حصولهم على الحماية(التطعيم) لتحدث المناعة المجتمعية يختلف حسب المرض

What we are still learning

We are still learning how many people have to be vaccinated against COVID-19 before the population can be considered protected.

As we know more, CDC will continue to update our recommendations for both vaccinated and unvaccinated people.

New Variants السلالات الجديدة

What we are still learning

We are still learning how effective the vaccines are against new variants of the virus that causes COVID-19. مازال العلماء يدرسون فاعلية (اللقاحات) التطعيمات بالنسبة للسلالات الجديدة من الفايرس المسبب لكوفيد 19

New variants of the virus that causes COVID-19 are spreading in the United States. Current information suggest that COVID-19 vaccines authorized for use in the United States offer protection against most variants. However, some variants might cause illness in some people after they are fully vaccinated if they are circulating in the community.
