Updated Feb 25, 2025 | 11:15 AM IST

SummaryAs 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. However, there are other sets of regulation too that supervises your eligibility. Find out here.

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

Just One Psilocybin Use May Lead to Lasting Positive Brain Changes, Study Finds

Updated May 6, 2026 | 07:00 PM IST

Summary​The study participants noted that they had experienced more psychological insight after taking the 25 mg of psilocybin than they had after the 1 mg placebo, and noted "feeling optimistic about the future".

Psilocybin is the active ingredient found in magic mushrooms, and a new study shows that just one high dose (25 mg) is enough to cause alterations in the brain’s structures and help improve mental health.

The changes could explain why some people report psychological benefits from the experience, revealed the study published in the journal Nature Communications. The study found that the effect may last for up to a month after the experience.

In the study, researchers from the University of California, San Francisco, and Imperial College London argue that the effect may lead to “subsequent improvements in mental health”.

"Psychedelic means 'psyche-revealing,' or making the psyche visible," said senior author Robin Carhart-Harris, Professor of Neurology at UCSF.

"Our data shows that such experiences of psychological insight relate to an entropic quality of brain activity and how both are involved in causing subsequent improvements in mental health. It suggests that the trip—and its correlates in the brain—is a key component of how psychedelic therapy works," Carhart-Harris added.

How A Psychedelic Trip Improved Brain Health

Psilocybin has been the subject of several studies in people that have found it appears to alleviate symptoms of depression and anxiety. It has also shown promise in addiction medicine.

In the latest study on 28 people, none had a diagnosed mental health condition. The team gave the participants a 1 mg dose of psilocybin, which the researchers regarded as a placebo, and then monitored them with electroencephalography (EEG), which records brain activity from electrodes on the scalp.

One month after the placebo, the subjects were given 25 mg of psilocybin, a dose capable of eliciting a strong psychedelic trip.

After each experiment, the researchers measured the participants’ psychological insight, well-being, and cognitive ability. They also examined brain activity with functional MRI (fMRI) and brain connectivity with diffusion tensor imaging (DTI).

The results showed that within 60 minutes of taking the 25 mg dose of psilocybin, the EEG revealed higher entropy — which means that the brain was processing a richer body of information under the psychedelic.

A month later, the researchers looked at their subjects' brains with DTI, which measures the diffusion of water along neural tracts in the brain, and found that they were denser and had more integrity. This is the opposite of what happens in aging, which makes these tracts more diffuse.

While the result is a never-before-seen sign of how psychedelics can change the brain, the researchers cautioned that more work needs to be done to better understand the meaning of this change.

The participants noted that they had experienced more psychological insight after taking the 25 mg of psilocybin than they had after the 1 mg placebo, and noted "feeling optimistic about the future".

A month after the study, they also did better on a test of cognitive flexibility.

"Psilocybin seems to loosen up stereotyped patterns of brain activity and give people the ability to revise entrenched patterns of thought," said Taylor Lyons, a research associate at Imperial College London and the first author of the paper. "The fact that these changes track with insight and improved well-being is especially exciting."

The findings could improve treatment for people with mental illness with psilocybin, for example, by ensuring that the right dosage is used to produce the right amount of brain entropy to promote insight.

Untreated Eczema Could Lead To Chronic Asthma: Dermatologist Answers FAQs

Updated May 5, 2026 | 10:00 PM IST

SummaryEczema is a skin disorder, but how it contributes to asthma risk is relatively unknown.

Every year on May 5, World Asthma Day is observed, an event that aims at spreading awareness about the respiratory disorders. While asthma is becoming a common occurrence in India, citing excessive pollution and unhealthy lifestyle choices. But in a shocking revelation on the occasion, Dr. Gitika Sanodia, Consultant Dermatologist at Dr L H Hiranandani Hospital, Powai, revealed that leaving eczema untreated could lead to chronic asthma. Talking about it, Dr Sanodia answered some common FAQs about eczema and asthma.

Can untreated eczema cause asthma?

Yes, especially for those suffering from early childhood onset of moderate/severe atopic dermatitis. Eczema is not always limited to being solely a skin condition. In many cases, patients who suffer from eczema actually have one part of the atopic triad, which means the patient's skin barrier is dysfunctional, allowing for allergens to enter and sensitize the immune system. With time, the same tendency can impact other organs, causing allergic rhinitis or asthma. However, it must be noted that not all children with eczema develop asthma.

Why does everybody treat eczema as merely a skin problem?

Because of symptoms including itching, dryness, redness, scaling, and oozing from the skin. The families take care to control the acute phase of eczema while ignoring the patient's predisposition to allergies. Furthermore, atopic dermatitis is an inflammatory skin condition that is accompanied by impaired skin barrier function, immune dysfunction, and environmental factors. Moreover, according to DermNet, atopy is a term used for conditions where eczema, rhinitis, and asthma happen together.

Early signs for which parents and adults should be vigilant

Parents should worry if their children with eczema exhibit recurrent coughs, wheezing, noisy breathing, difficulties breathing during playtime, nighttime coughing, chest tightness, frequent sneezing, nasal blockage, allergic rhinitis, or exacerbation of symptoms following exposure to dust, animal dander, pollens, airborne particles, or fluctuating environmental conditions.

Is eczema therapy sufficient to prevent the development of asthma?

Successful treatment of eczema can help minimize the chances of allergens penetrating the skin barrier and allergic inflammation. Nonetheless, it would not be accurate to predict with certainty that eczema therapy will effectively prevent the onset of asthma. Literature recommends the prompt restoration of the skin barrier function, regular application of moisturizing agents, avoiding triggers such as fragrances and harsh soaps, managing flare-ups with prescription corticosteroid creams, controlling infections, and referring patients with severe eczema cases.

Is it a significant public health concern?

Yes. This condition is becoming more common, especially among children. If not controlled effectively, eczema will result in poor sleeping habits, difficulties with academic performance, reduced quality of life, greater susceptibility to infections, and potentially even links to other allergies. People lack sufficient information regarding the condition because they normally medicate themselves by applying whatever ointment or steroid to their skin.

Is Your Home Making Your Asthma Worse? Doctors Highlight Indoor Triggers

Updated May 6, 2026 | 03:58 PM IST

SummaryFrom bedding to pets to scented candles and furry friends, asthma triggers can be found indoors. Doctors urged patients to identify their personal triggers and act early, because managing their indoor environment is just as critical as managing their medication.
Is Your Home Making Your Asthma Worse? Doctors Highlight Indoor Triggers

Asthma is often thought of as an "outdoor" problem, with triggers such as smog, pollen, or car exhaust. But for many, the real danger may be sitting right there on the sofa or hiding under the sink.

The chronic condition affects over 260 million people. It is also responsible for over 450,000 deaths each year worldwide.

If you're doing everything right with your inhaler but still feel that tightness in your chest, it’s time to look at silent indoor triggers.

1. The Bedding "Dynasty"

“It’s a bit unsettling, but your mattress is likely home to millions of microscopic dust mites. They love the warmth and humidity of a bed. You won't see them, but you’ll feel them,” Dr. Sandeep Nayar, Principal Director & HOD - Chest & Respiratory Diseases, BLK Max Super Speciality Hospital, told HealthandMe.

The Fix: Don’t just wash your sheets; use hot water (60°C). If you haven't encased your pillows in allergen-proof covers yet, make that your priority this weekend.

2. Moisture is the Enemy

Dr Nayar said mold isn't always a giant green patch. It hides in the "sweat" behind your wallpaper or the damp corners of a bathroom that doesn't vent well. If a room smells even slightly musty, mold spores are likely in the air.

The Tip: Keep your home's humidity below 50 per cent. A simple dehumidifier can sometimes do more for your lungs than an extra dose of medicine.

3. It’s Not Just the Fur

Many people think "hypoallergenic" pets are the cure. It’s actually a protein in pet saliva and skin flakes (dander) that causes the flare-up.

The Reality: Even if you keep the dog off the bed, dander travels on your clothes. HEPA air purifiers are a must-have if you share your home with a furry friend.

4. The "Clean" Smell Myth

That "fresh lemon" scent or your favorite scented candle? Those are Volatile Organic Compounds (VOCs). To a sensitive lung, those chemicals are irritants, not cleaners.

The Switch: Move toward fragrance-free products. If a cleaning spray makes you cough, your body is telling you everything you need to know.

5. Urban Uninvited Guests

In cities, cockroach droppings are a massive, often ignored asthma trigger. Their proteins mix with household dust and get kicked up every time you walk across the floor.

The Strategy: Seal the cracks in your walls and keep the kitchen bone-dry.

Other asthma triggers include dust mites, pet dander, indoor smoke, and strong cleaning agents that can worsen symptoms over time

How To Prevent Indoor Asthma Triggers

Dr. Manisha Mendiratta, Director & Head - Pulmonology, Sarvodaya Hospital, Faridabad, told HealthandMe that the key is prevention through simple, consistent habits. To make a meaningful difference, the expert urged people to

  • ensure good ventilation,
  • reduce indoor humidity,
  • clean soft furnishings regularly,
  • avoid aerosol-based products.
  • ise air purifiers,
  • keep windows open when possible,
  • creating a smoke-free space.
“Managing asthma is about more than just a prescription. It’s about making your home a place where your lungs can finally relax,” Dr Nayar said.

“Most importantly, patients should identify their personal triggers and act early, because managing their indoor environment is just as critical as managing their medication,” added Dr. Mendiratta.
