You’ve probably seen the videos or heard the rumors. Social media, especially TikTok, has a way of taking niche health "hacks" and blowing them into massive trends overnight. The latest? Putting an ice cube in your butt. It sounds bizarre, maybe even a little funny, but people are actually doing it to manage everything from hemorrhoid pain to basic curiosity. Let's be real—the internet is a weird place, and while some "natural remedies" are harmless, shoving a frozen block of water where the sun doesn't shine carries some actual medical risks that influencers rarely mention between their jump cuts.
I've talked to proctologists and gastrointestinal experts about this. They aren't laughing.
The human rectum is a delicate environment. It’s lined with mucosal tissue that is incredibly sensitive to temperature and friction. When you introduce something at a sub-zero temperature directly to that tissue, you aren't just "chilling out." You're potentially causing thermal injury. Think about it. Your internal body temperature is roughly 98.6 degrees. An ice cube is 32 degrees or lower. That’s a massive jump.
The Science of Cold and the Rectal Wall
Why do people even consider putting ice cubes in their butt? Mostly, it’s about the "vasoconstriction" effect. When you apply extreme cold to blood vessels, they shrink. For someone suffering from Grade I or Grade II internal hemorrhoids, this can feel like an instant relief from throbbing or swelling. However, there is a massive difference between an ice pack applied externally to the perianal area and inserting a raw ice cube internally.
When ice touches the mucosal lining, it can actually stick. We've all seen the movie A Christmas Story where the kid sticks his tongue to the frozen pole. The same thing can happen inside the rectum. The moisture on the rectal wall freezes instantly upon contact with the ice, causing the cube to adhere to the tissue. If you try to move it or if the tissue shifts, you can literally tear the top layer of the lining off.

It’s called a "cryogenic burn." It sounds fancy, but it basically means you’ve killed the top layer of cells through freezing.
What the Doctors Say
Dr. Evan Goldstein, a prominent anal surgeon and founder of Bespoke Surgical, has been vocal about the dangers of DIY rectal treatments. He often emphasizes that the "anoderm"—the skin of the anal canal—is packed with sensory nerves. Damaging these nerves with extreme cold can lead to long-term sensitivity issues or even fecal incontinence if the internal sphincter muscle reacts poorly to the thermal shock.
The Risk of Thermal Shock and Tearing
It isn't just about the temperature. It's the shape. Ice cubes are rarely perfectly smooth spheres. They have sharp edges, corners, and ridges from the freezing process.
The rectum is not a straight, smooth pipe. It has folds called the Columns of Morgagni. Shoving a sharp-edged ice cube past the anal sphincter can cause micro-tears or "fissures." These are notoriously difficult to heal because, well, you have to use that part of your body every day. A fissure can turn a minor curiosity into months of chronic pain and potential infection.

Then there’s the "vagal response." The rectum is heavily tied to the vagus nerve. Sudden, extreme temperature changes can trigger a vasovagal reaction, causing your heart rate to drop and making you feel dizzy or even faint. Passing out with an ice cube inside you is a recipe for a very awkward emergency room visit. Honestly, ER doctors have seen it all, but that doesn’t mean you want to be the reason they have a new story to tell at the nurses' station.
Better Alternatives for Hemorrhoid Relief
If you are looking at the ice cube trend because you are in genuine pain, skip the freezer tray. There are medically backed ways to get that cooling sensation without the risk of frostbite on your insides.
- Sitz Baths: This is the gold standard. Warm water (not hot!) helps relax the sphincter muscle and increases blood flow to the area to promote healing.
- Witch Hazel: Tucks pads or similar products use witch hazel, which is a natural astringent. It provides that "cooling" feeling safely.
- External Cold Compresses: If you must use ice, wrap it in a thick, soft towel and apply it to the outside only. Limit this to 10 minutes.
- Topical Creams: Over-the-counter hydrocortisone creams or Preparation H are designed for this specific tissue. They won't give you a thermal burn.
Common Misconceptions About Internal Cooling
A lot of people think that because the body eventually melts the ice, it’s "self-cleaning" or "harmless." That’s a dangerous way to look at it. The water that melts from an ice cube isn't necessarily sterile. If you're using tap water from an old ice tray that hasn't been cleaned in months, you're introducing bacteria directly into an area that might already have micro-tears.
Also, the "cleanliness" of the ice tray matters. Cross-contamination in the freezer is real. Do you really want whatever was on that frozen chicken breast potentially interacting with your internal mucosal lining? Probably not.

When to Actually See a Professional
If you’re even considering the ice cube method, you’re likely dealing with some level of discomfort that needs a real solution. If you notice bright red blood on the toilet paper, persistent itching, or a feeling of fullness that won't go away, it’s time to call a gastroenterologist.
Self-treating with ice cubes is like trying to fix a leaking pipe with a piece of gum—it’s a temporary, poorly thought-out distraction from a problem that might need a real medical fix, like rubber band ligation or prescription-strength suppositories.
Practical Steps for Rectal Health
- Hydrate: The best way to avoid the need for "rectal cooling" is to keep your stool soft. Drink plenty of water.
- Fiber is King: 25–35 grams a day. If you can’t get it from food, use a supplement like psyllium husk.
- Stop Straining: Don’t spend 20 minutes on the toilet scrolling through your phone. That pressure is exactly what causes the swelling people try to fix with ice.
- Consult an Expert: If the pain is "ice cube worthy," it's "doctor worthy."
The bottom line? Keep the ice in your drink. Your body has complex systems for regulation and healing, and shocking those systems with frozen objects is more likely to cause an injury than it is to provide a cure. If you've already tried it and feel sharp pain, bleeding, or numbness that lasts more than an hour, don't wait for it to "thaw out." Get checked out by a professional to ensure you haven't caused a mucosal tear or a deep-tissue thermal burn.
