Have you ever been so tired that the moment you hit the bed, you feel like you are sinking in your mattress? Or did you ever feel your leg twitch in middle of your sleep? Did you feel like you moved your leg to prevent yourself from falling down? If yes, then you are in for a great read!

Why does this happen?

You are not alone, this happens to around 70% of the total population in some way or another. Although these are signs of sleep disorders, it can also happen to people who are otherwise healthy. Sleep disorder specialists believe that there are certain common triggers that leads to such a sensation.

Our brain is exceptional and sometimes when we dream, it makes us believe that we our part of the dream. And if you are falling from somewhere in your dream, chances are, you would feel like you are falling in real life. This experience is known as hypnic jerk, the movement of your muscle that helps you be safe from that fall, or the imaginary one.

What causes it? When we sleep, our bodies become paralyzed, but that does not mean that our muscle control is not totally off. Rather, a slow, dimmer switch. When the dim switch randomly is turned on, we get jerky movements in our sleep.

This involuntary muscle movement is also called myoclonus or hypnic myoclonus, that transitions as you shift from one sleep phase into another.

What Could Cause It?

There are many theories on what might be causing it. One of them is that when you are at this stage of sleep, you are still not in deep sleep and your brain misinterprets it as wakefulness, however, at the same time your brain does not recognize your muscles to be moving. This is what leads your brain to send a message to your muscles to check-in. It is a way your brain tries to protect you.

Another theory is of course that of stress. When you are stressed, your mind might be racing, while your body is in stationary. This can also affect your sleep cycle and your sleep can be disrupted.

If you are on stimulant drugs or alcohol, it too can prevent you from achieving a good night sleep. If you have consumed too much caffeine then too your muscles can twitch to make you stay awake.

Furthermore, lack of sleep could also be the reason why your mind is used to staying awake even if your body really needs the rest.

Periodic Limb Movement Disorder

While the falling sensation in sleep is quite common, and happens to healthy people, a severe form is the Periodic Limb Movement Disorder (PLMD). PLMD is a repetitive cramping or jerking of legs during sleep. It is a movement disorder that happens only during sleep. It is called "periodic" because the movements are repetitive and rhythmic, which means it occurs in every 20 to 40 seconds. It is also often linked with restless legs syndrome, however, the two are not the same thing.

Restless leg syndrome on the other hand is a condition that involves strange sensations in the legs and arms while awake and an irresistible urge to move the limbs to relive the sensations.

What causes PLMD may be more severe things, including diabetes, iron deficiency, spinal cord tumor, spinal cord injury, sleep apnea, uremia, anemia, narcolepsy, or certain medications.

Did you also wake up with a mild cold? A sneeze, blocked nose and a sore throat. It is worse because you had just shaken off the miserable cold and your energy was finally coming back and then now again you are sneezing. So, now the question is, could you really get the same cold twice, or is it just your bad luck?

As per the National Health Service, UK (NHS), adults could get an average of 2 to 4 colds a year. The NHS, UK notes that the viruses behind them behave in a complicated way. This is because some mutate quickly, and some stay in your system. This is why your body's ability to fight them off can differ depending on how well does your immune respond.

Catching The Same Cold, Twice

Conventionally, it is believed that once you have a virus, your body recognizes it and does not let you catch the same virus again. However, this is not the case, always.

Professor Brain Ferguson, who is the professor of viral immunity at the University of Cambridge told Yahoo UK, that it is possible to catch cold twice. This is due to the levels of antibodies that we have in our system.

Ferguson says, "It depends on the quality of the antibodies that your body generates when you get infected the first time. Sometimes your body might make really good ones, and that will stop you being reinfected with the same virus later. But another person might not, and they can catch the same virus, exactly the same one, again later."

The expert further added, "It is also down to the actual molecules, and the constituents of the virus, like proteins and things you make antibodies against. The longer they exist in your body, the better the antibody response tends to be."

This means that the cold can stay in your system, and the longer it stays the better your immune system will be prepared to build up a stronger defense.

Reinfection Time: How Long Does It Take?

If you had two colds very close together, you may not have had enough time to build immune response the first time. Ferguson says, "Reinfection can be very fast."

"It can be as soon as a couple of weeks if the antibody response is very weak... You might pick up a virus and get a few minor symptoms, but fight it off really quickly. In that case, you get much weaker antibodies that fight the virus, which means the same virus appears in your system again very quickly."

This means your body only has a "fleeting encounter" with the virus and thus it won't remember it well enough to protect you the next time. However, a more severe cold may trigger a stronger immune response, which can work as a longer-lasting protection.

Why Some People Catch More Often?

This has something to do with genetics. This is because of their immune system, how good it works against different infections. As Ferguson says, "Some people are just naturally better or worse at fighting off viruses or bacteria due to their genetic makeup."

While it is believed that multivitamins and supplements can help "boost" immunity, Ferguson says that the evidence is mixed.

There’s not a great evidence base for [vitamins] for repeat infections," he says. However, Ferguson adds there is evidence that people who spend more time outside and get more vitamin D tend to have a slightly better-functioning immune system.

Flu season has arrived, and while the summer wave of COVID-19 has subsided, a winter increase is expected. Vaccines are available for both viruses, prompting many to ask about timing, especially if they haven’t received their shots yet. With the CDC updating guidelines, rules around vaccination are constantly evolving, so the most common question is: can you get your COVID and flu shots at the same time?

Can You Get Your Covid And Flu Shots At The Same Time?

The COVID-19 vaccine can be administered alongside a seasonal flu shot for those who prefer to get both at once. It is considered completely safe. “There are no recommendations against it; it mainly comes down to personal preference,” Dr. Mike Ren, an assistant professor of family and community medicine at the Baylor College of Medicine explained. He added that some people may experience mild fatigue with vaccines, and getting multiple shots at the same time could slightly increase that effect.

Many people are already familiar with how their bodies react to flu and COVID-19 vaccines. The COVID shot can sometimes cause soreness in the arm, so it’s recommended to avoid getting both vaccines in the same arm if that happens. For those who experience minimal side effects, there’s no disadvantage to receiving both shots at the same visit. Some choose to space them out simply based on convenience.

Which Covid Shot To Get?

For individuals who have experienced strong reactions to the Pfizer or Moderna mRNA COVID vaccines, the Novavax shot, which uses a more traditional protein-based method may offer an alternative with fewer temporary side effects, according to Caitlin Rivers, an infectious-disease epidemiologist and senior scholar at the Johns Hopkins Center for Health Security.

Males aged 12 to 29 may particularly consider Novavax, as it carries no known risk of myocarditis, a rare heart inflammation sometimes associated with mRNA vaccines. Andrew Pavia, a pediatrics infectious-disease physician at the University of Utah, noted that myocarditis cases linked to mRNA vaccines are generally mild, and COVID-19 itself poses a higher risk of heart complications.

Pavia also explained that there are no major differences between the current Moderna and Pfizer vaccines, so people can choose whichever is more convenient or available.

When Should You Get A Flu Vaccine?

The ideal time to get a flu vaccine is generally from late September through October. Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, recommends aiming to be vaccinated before Halloween, in line with CDC guidance.

While many pharmacies begin offering flu shots as early as July or August, Dr. Peter Chin-Hong, an infectious disease specialist at the University of California, San Francisco, advises waiting a bit longer. This is because vaccine protection can wane after a few months, and flu cases often peak between December and February.

Even if you miss the early window, it’s still worthwhile to get vaccinated. “Some protection is better than none,” Dr. Chin-Hong emphasizes.

Staying up to date with both COVID-19 and flu vaccinations is an important step in protecting your health during the respiratory virus season. Getting the shots at the same time is safe and convenient for most people, though minor side effects like fatigue or soreness may be slightly increased.

Nearly five years after the COVID-19 pandemic began, new variants of the virus are spreading again, bringing with them some unusual symptoms. The main strains currently circulating are called Stratus and Nimbus. According to the NHS, Stratus, which includes the XFG and XFG.3 variants, has caused a 60 percent rise in Covid hospitalisations.

As cases increase worldwide, one woman who recently tested positive described this infection as the “worst it’s ever been.” With more people falling sick, the NHS continues to update its warnings and guidance.

Could That Toothache Be ‘Frankenstein’ Variant?

A woman from the US, Nev, shared on TikTok that she began feeling slightly unwell on August 30, with mild congestion and one blocked nostril. The next day, she noticed a scratchy throat and continued congestion, but later that night, her symptoms worsened as she experienced pain in her teeth, jaw, and head. Her post quickly drew comments from others who said they had also suffered similar symptoms while infected with Covid.

The Stratus strain has been linked to a sudden hoarse voice, while the Nimbus strain often causes severe throat pain described by some as feeling like “swallowing razor blades.” Health officials in the UK have warned that Covid is still leading to serious illness and deaths and have urged people to stay alert to new and unusual symptoms.

Frankenstein Variant Symptoms

The “Frankenstein” variant, officially known as Stratus (XFG), is a recombinant form of the Omicron strain of COVID-19. Its symptoms often resemble those of a seasonal cold or flu. While most infections are mild, some patients have reported unusual signs such as sudden hoarseness or a raspy voice.

Common symptoms include:

• Fever
• Sore throat
• Cough
• Runny or blocked nose
• Fatigue and body aches
• Headache
• Digestive issues

Are Frankenstein And Stratus Variant Same?

The Frankenstein variant and the Stratus variant refer to the same strain of COVID-19, officially known as XFG. The nickname “Frankenstein” emerged because the variant is a recombinant of multiple Omicron sublineages, essentially a genetic mix that combines traits from different versions of the virus. The scientific name Stratus (XFG) is the formal term used by health authorities such as the UKHSA.

According to the UK Health Security Agency (UKHSA), anyone showing symptoms of a respiratory infection such as COVID-19, especially if they have a fever or feel too unwell to continue daily activities should try to stay home and avoid contact with vulnerable people.

If staying home isn’t possible, the agency advises taking extra precautions to reduce the risk of spreading infection. This includes wearing a well-fitted mask with multiple layers or a surgical mask, avoiding crowded or poorly ventilated spaces, and opting for outdoor exercise where there is minimal contact with others. People are also urged to cover their mouth and nose when coughing or sneezing, wash their hands often with soap and water or use sanitizer, and avoid touching their face.

The simplest way to confirm if you have COVID-19 is by taking a test, which can be purchased at most pharmacies.
