How Long After a Tattoo or Piercing Can I Donate Blood?

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

Kidney Health Myths That Are Doing More Harm Than Good

Updated May 7, 2026 | 07:00 AM IST

SummaryStaying hydrated matters, but excessive water intake isn’t beneficial for everyone—especially in advanced chronic kidney disease (CKD), where fluid intake often needs to be carefully limited to avoid complications.
Kidney Health Myths That Are Doing More Harm Than Good

Kidney disease is one of those conditions where myths quietly cause a lot of damage. Misinformation about symptoms, diet, medicines, and treatment can delay diagnosis, worsen kidney health, and prevent people from taking simple steps that could protect their kidneys early on.

Myth: Kidney disease is rare.

Fact: It’s actually quite common, but many people don’t even know they have it.

Myth: You’ll feel it if something is wrong.

Fact: Early chronic kidney disease (CKD) is usually silent, and symptoms often appear only after significant damage has already occurred.

Even something as simple as a slightly raised creatinine is often ignored.

Fact: Even mild elevations can signal a meaningful loss of kidney function.

Myth: Dialysis cures kidney disease.

Fact: Dialysis does not cure kidney disease. It only replaces some kidney functions to help keep the body in balance.

Myth: If dialysis is needed in Acute Kidney Injury (AKI), it means lifelong dialysis.

Fact: Dialysis in AKI may be temporary. In advanced CKD, however, it is often long-term or lifelong unless a kidney transplant is performed.

Diet myths don’t help either

Myth: More water is always better.

Fact: Hydration is important, but too much water isn’t helpful for everyone—especially in advanced CKD, where fluid intake may need to be restricted.

Myth: All kidney patients should eat the same diet.

Fact: Kidney diets are highly individualized. High-protein diets, often seen as healthy, can increase stress on damaged kidneys. Plant-based proteins can be a suitable alternative in many cases.

Myth: Herbal or indigenous remedies can cure or prevent kidney disease.

Fact: Many of these remedies are unregulated and may actually worsen kidney damage because of hidden toxins or heavy metals.

Myth: Painkillers are harmless.

Fact: Regular use of medicines like NSAIDs can quietly damage the kidneys over time.

At the end of the day, kidney disease isn’t just about treatment—it’s about awareness. Getting the facts right can make all the difference.

Weather Changes Can Spark Migraines and Sinus Trouble: Here’s How to Protect Yourself

Updated May 6, 2026 | 11:00 PM IST

SummaryWeather changes can cause chemical imbalances in the brain, specifically affecting serotonin levels, which are involved in migraine development. They can also cause inflammation or a "pressure difference" in the sinuses.
Weather Changes Can Spark Migraines and Sinus Trouble: Here’s How to Protect Yourself

There are many components of weather that are reported to affect migraine, such as barometric pressure, humidity, temperature, and seasons. A drop in pressure (often before a storm) can create a pressure imbalance between the environment and the sinuses/inner ear, stimulating nerves and causing headaches.

Rapid shifts in temperature or intense cold/heat can trigger migraine attacks. Both high humidity and very dry air can trigger migraine symptoms. Bright Sunlight or Intense sun exposure, especially reflecting off snow or water, is a significant trigger for migraine.

Weather Changes: Brain Imbalances

Weather changes can cause chemical imbalances in the brain, specifically affecting serotonin levels, which are involved in migraine development. They can also cause inflammation or a "pressure difference" in the sinuses.

Both spring/summer (due to heat and allergens) and winter (due to cold/dry air) can trigger migraines and sinus problems. While many studies report weather as a trigger, some studies suggest that our perception of the trigger can exceed the actual statistical impact.

Often, it is a combination of factors, such as allergies in the spring or the flu in autumn, that triggers the headache, rather than just the air pressure.

Maintaining a migraine diary for at least 90 days helps identify specific weather patterns that trigger your attacks.

Seasonal Allergies And Sinus

Seasonal allergies do not cause migraine attacks, but migraine is commonly misdiagnosed as a sinus headache, because some symptoms can overlap. It is common for migraine to be associated with forehead and facial pressure over the sinuses, as well as a blocked or runny nose.

However, sinus issues may be accompanied by a fever rather than a migraine. Migraines can cause activation of the nerves in the face (referred to as cranial autonomic activation), which can lead to the blocked, congested feeling.

How To Stay Safe

If weather changes are a trigger for you, this can be difficult to avoid, and beyond your control, but it can be useful to keep an eye on the weather forecast. A preventive treatment may be needed to reduce the overall sensitivity to such changes, allowing you more freedom to plan your daily activities. When you think the weather might increase the risk, it is useful to treat early to shorten and completely stop the migraine attack.

Attacks that are treated early will have fewer debilitating symptoms by not becoming fully developed and severe. Drink enough water to make up for extra fluid loss on warmer days and during physical activities.

Consider taking water with you when out to remain well hydrated and to compensate for excessive sweating. Consider staying indoors during the peak hours of brightness if that is an option.

If going out, be prepared by wearing protective sunglasses or a hat to minimize glare and light. Use a humidifier to maintain indoor humidity between 40-50% to prevent nasal passages from drying out, especially in winter.

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

Updated May 7, 2026 | 01:30 PM IST

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

What Is Psilocybin? Its Effects on the Brain, Explained

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.
