Are you that kind of person who celebrates milestones of your life with getting a tattoo? These milestones could be anything, including the things you achieved, or the things you could not achieve but taught you a lesson. If you are this person, then you must have wondered if you can donate blood with all the tattoos on your body? There are lots of rumors on how can one donate blood, or if at all they are allowed to donate blood. So let's get into its nitty gritty!

As per American Red Cross, in most states, a tattoo is acceptable if the tattoo was applied by a state-regulated entity. Which means the tattoo artist must be licensed and must practice following all the guidelines, using sterile needles and ink that is not reused. The same is the guideline for cosmetic tattoos, which includes microblading of eyebrows. If it is done by a licensed artist in a regulated state, then it is acceptable.

However, if you got your tattoo in a state that does not regulate tattoo facilities, you must wait three months after it was applied.

The states that do not regulate tattoo facilities are:

• Arizona
• District of Columbia
• Georgia
• Idaho
• Maryland
• Massachusetts
• Nevada
• New Hampshire
• New York
• Pennsylvania
• Utah
• Wyoming

Body Piercing

Similar is the case with body piercings. It has to be done following the regulation, here the key is that the instrument used has to be a single-use equipment and disposable. Which means if you are getting it by a gun, or an earring cassette, they have to be disposable. In case you got your piercing with a reusable gun or a reusable instrument, you will be required to wait for three months.

Three-Month Wait Period

The reason behind the wait time is associated with the concerns of hepatitis, which could be easily transmitted from donors to patients through transfusion. All blood donations are thus tested for hepatitis B and hepatitis C, with several tests. However, not always are these tests are perfect, thus the three-month period is given.

What Dangers Loom Over?

Donating blood after getting a tattoo can be dangerous as unclean tattoo needle could carry bloodborne viruses, which are hepatitis B, hepatitis C and HIV. In 2020, the Food and Drug Administration (FDA) updated its guideline, making the wait time shorter from one year to three months. This is because if you contract a bloodborne illness, it could be detectable within the period of 3 months.

What else makes you ineligible to donate blood?

There are other reasons why you may not be allowed to donate blood. As per the American Red Cross, you are not allowed to donate blood if you have

• hepatitis B or C
• HIV
• Chagas disease, which is a parasitic infection that kissing bugs cause
• leishmaniasis, a parasitic infection that sand flies cause
• Cruetzfeldt-Jakob Disease (CJD), a rare disorder that leads to mental deterioration
• Ebola virus
• hemochromatosis, which means extreme build up of iron
• hemophilia
• jaundice
• sickle cell disease

As per the National Institutes of Health (NIH) Blood Bank, these conditions make you permanently ineligible from donating blood.

While there are certain conditions that makes your permanently ineligible, there are other conditions that makes you temporarily ineligible from donating blood. These include:

• If you have a bleeding condition, and have issues with your blood clotting
• If you have received transfusion from a person
• If you have cancer. Here, the eligibility depend son the type of cancer you have
• If you have recently underwent a dental or oral surgery. In such a case, you would have to wait for three days
• If you had a recent heart attack, heart surgery or angina. You must wait for 6 months
• If you are pregnant, you can only donate blood after 6 months after delivering your child

Santa Claus is bad for your health! This is a statement by Dr Nathan Grills, a Public Health Fellow in the Department of Epidemiology and Preventative Medicine, Monash University, Australia. Why is he saying this right ahead of Christmas?

Writing for an article in the British Medical Journal's Christmas issue (BMJ), he says, "Santa only needs to affect health by 0.1% to damage million of lives". He says it would be better if his popularity was rather used to promote healthy living.

Why Is Santa Claus Unhealthy?

Santa Claus's portrayal is where the concerns lie. This was not the first time someone has talked about. In fact, The Conversation in December 2024, talked about this exactly. If you look at Santa, he stands anywhere between 5'6" to 6'6" and weighs between 80Kgs to 136Kgs. He also carries a lot of weight around his belly, which, some may say, keeps him insulated as he sleighs through the snowy lands, but is sure overweight and obese. These portrayal promotes an unhealthy living.

Dr Grils also writes that Santa should rather share Rudolf's snack of carrots and celery sticks than brandy and mince pies, and swap his reindeer for a bike or a walk.

After reviewing existing literature and online sources to understand Santa Claus’s possible impact on public health, the analysis found no peer-reviewed studies directly addressing the issue. What did stand out, however, was the exceptionally high level of awareness of Santa among children. In fact, surveys of American schoolchildren showed that Santa Claus was recognized more widely than almost any other fictional character, second only to Ronald McDonald.

The doctor says that Santa is also used for selling products, which are mostly harmful, and this happens on global scale, which means, people get inspired. "Santa sells, and sometimes he sells harmful products. Like Coca-Cola, Santa has become a major export item to the developing world."

While Santa has been banned from smoking, but his images of enjoying a pipe or cigar are easily found on Christmas cards. The depiction of Santa does form a public perception, argues the doctor.

Dr Grill also notes that Santa may be promoting potential drink-driving, especially when someone follows the tradition to leave him a brandy to wish him well on his travels, while he has billion houses to visit.

Can Santa Spread Diseases?

Dr Grill says that he can spread diseases. If Santa sneezes or coughs around 10 times a day, all the children who sit on his lap may also end up catching the flu along with their Christmas presents.

However, it is important to note that these are views expressed by the doctor and no actual studies have been conducted on the same, Though Dr Grill does indicate for more research before calling for authorities to regulate Santa's activities. For now, Dr Grill proposes a new image for Santa, a healthier one. A slim Santa on a treadmill.

For years, the appendix was brushed off as a useless leftover from human evolution. Many of us grew up believing that it served no real purpose and was better off removed at the first sign of trouble. But science now tells a more interesting story. This small, finger-like pouch attached to the large intestine quietly supports gut health and immunity in ways that were long overlooked.

What exactly is the appendix?

The appendix is a narrow tube connected to the cecum, located in the lower right side of the abdomen. It usually measures between 7 and 10 cm, although its size and position can vary widely from person to person. In some people, it may be just a couple of centimeters long, while in others, it can extend much further. This variation is also why appendicitis pain can sometimes feel confusing or atypical.

Not useless after all

The biggest shift in understanding the appendix came from research into gut bacteria. The appendix appears to act as a safe storage space for beneficial microbes. During bouts of severe diarrhea or intestinal infections, large amounts of gut bacteria are flushed out. The appendix helps reintroduce these good bacteria once the illness passes, helping the digestive system recover faster.

It also plays a role in immunity, especially during early life. The appendix contains lymphoid tissue, which exposes immune cells to substances passing through the gut. This helps the body learn how to respond to harmful invaders while tolerating harmless ones. While humans can survive perfectly well without an appendix, its presence offers subtle support to the immune and digestive systems.

Why appendicitis happens

Despite its benefits, the appendix is still prone to inflammation. Appendicitis is one of the most common abdominal emergencies worldwide. It usually occurs when the appendix gets blocked, often due to hardened stool, infection, or rarely, abnormal growths. Once blocked, bacteria multiply, causing swelling, pain, and infection.

The classic warning sign is pain that starts near the belly button and gradually shifts to the lower right abdomen. This may be accompanied by fever, nausea, vomiting, and loss of appetite. Ignoring these symptoms can be dangerous. If left untreated, the appendix can rupture, leading to serious and potentially life-threatening complications.

Busting Common Myths

There are many myths surrounding the appendix. One of the most common is that fruit seeds or spicy food cause appendicitis. There is no evidence to support this. Another misconception is that appendicitis can settle on its own. While pain may temporarily reduce, the underlying inflammation usually worsens.

Many people also worry that removing the appendix will harm digestion or require lifelong dietary restrictions. In reality, most people return to normal eating habits and daily routines after recovery, with no long-term health issues.

How appendicitis is treated

Surgery remains the most reliable treatment for appendicitis. Today, minimally invasive techniques such as laparoscopic or robotic surgery are widely used. These involve small incisions, less pain, quicker recovery, and shorter hospital stays. In complicated cases, open surgery may still be required.

In selected cases of mild, uncomplicated appendicitis, antibiotics may be used initially. However, studies show that while symptoms may improve, there is a higher chance of recurrence within months. For this reason, surgery continues to be the definitive, long-term solution for most patients.

Recovery after appendix removal is usually smooth. Many patients are able to walk the same day and return home within a day or two. Light meals are recommended initially, and heavy lifting is avoided for a few weeks. Long-term lifestyle changes are rarely needed, and most people forget about the surgery entirely once healed.

Delhi's air quality remained in "very poor" category, and the AQI stood at 342 at 8am, as per the Central Pollution Control Board. The 24-hour average AQI was logged at 412 under the "severe" category on Tuesday evening when Delhi's quality peaked to record the fourth severe air day in the month of December. With the air quality levels remaining continuously in the "very poor" category, Delhi's Chief Minister Rekha Gupta held a pollution review meet.

What Was Discussed In The Pollution Review Meet By Rekha Gupta?

A review meeting was held to discuss the rising air pollution levels in Delhi on Monday at the Delhi Secretariat. The meeting was attended by the officials from various departments, which also included the Public Works Department (PWD), Transport, Delhi Pollution Control Committee (DPCC), Environment, and others.

Post meeting, Delhi Environment Minister Manjinder Singh Sirsa said that the CM sought responses from multiple departments to discuss various aspects of pollution in the national capital. Sirsa also confirmed that a follow-up meeting will be scheduled on Thursday to continue the discussions on various steps that should be taken to bring down the levels of Delhi's AQI.

Rely On Public Transport - As A Solution To Delhi Pollution

On Sunday, a day before the meeting was held, Delhi's CM spoke on relying on public transport as a solution to Delhi's pollution. She said that the government aims to make the metro network "so comprehensive that people do not need to rely on private vehicles even for last-mile connectivity”.

Delhi's Pollution Is Now A Public Health Risk

An analysis by the Global Burden of Disease (GBD) 2023 found that air pollution is city's single largest health risk. The deaths rose from 15,786 in 2018 to 17,188 in 2023.

Another study published in Scientific Reports, a five-year study titled Respiratory Deposition of Particulate Matter in Delhi: A Five-Year Assessment of Exposure Patterns and Health Risks tracked how particulate matter settles inside the respiratory system and found that men's exposure can be up to 1.4 times higher, especially while walking or commuting. The study noted that men on average spend more time outdoors while working, commuting, or walking in traffic-heavy areas. This leads to an increase in exposure.

A different study published in Frontiers in Public Health, explored the data of 2,96,078 women and girls between the age of 16 to 55 years in Taiwan and correlated it with the long-term air pollution data between 2000 and 2013. None of these women had any history of dysmenorrhea before the survey had began.

Furthermore, a study published in Nature Communication notes that after four hours of exposure to particulate matter, it was found that people's ability to perform routine tasks and interpret emotions were highly impacted.

If Delhi is able to cut its local pollution by 50 per cent, the pollution too could drop by 50 per cent. The emission should happen across the airshed. However, the focus should be for a long-term action on the source of emission and not short-term optics like cloud seeding, smog towers, water sprinkling or air purifiers.

In fact, as per a study published in Sustainability (MDPI), an open access journal, which mapped Delhi's air quality between 1990 to 2022 and found that transports emit around 10 to 30% of pollution, whereas agricultural residue burning, which is a seasonal source of pollution leads to less than 3% of pollution, whereas firecrackers, another seasonal source, leads to less than 1% of pollution.
