Hot Farts: Why Do Some Feel Warmer Than Others or Even Burn?

You may experience the sensation of “hot farts,” or feeling that the air passed during a fart is warmer than normal. The truth is the temperature of your toots is typically the same. Here's why.

Culture & Entertainment

The average person farts, or expels gas from their rectum, 14 to 23 times per day. Many farts pass silently while you sleep. Others may come during the day, and those waves of gas can range from quiet but stinky to loud and odorless.

Occasionally, you may experience the sensation of “hot farts,” or feeling that the air passed during a fart is warmer than normal. The truth is the temperature of your toots is typically the same, but a few factors can make them feel warmer than normal.

Read on to find out what can cause that sensation and what you can do to keep gas passing tamed.

What causes burning farts?

On average, the temperature of the gas passed from your rectum is the same each time you break wind. Your farts may feel warmer in some instances. These causes may be to blame:

Low gas levels

It’s not bad to have fewer than normal farts. Each person’s gassiness level is unique and often based on the foods you eat and your lifestyle habits.

However, having less gas to pass may make toots seem hotter. That’s because when gas is expelled with a bit of force — that is, you have more to pass — it clears your rectum quickly. You don’t typically feel the air warm up around your anus.

If you have less gas, however, the gas may move slower with less force. In that case, the air may linger right around your bum, heating up the skin slightly.

Diarrhea

The temperature of your gas doesn’t increase when you have diarrhea, but the skin lining your anus and rectum may become sensitive as a result of the increased bowel movements. That can make everything more irritated and painful, including your farts.

Spicy food

What’s hot going into your body is likely to be hot coming out. Spicy foods often contain natural substances, such as capsaicin, which impart a fiery flame to your tongue — and they do much the same to your anus during a bowel movement.

The food itself won’t make the gas you’re passing hotter, but it may make the sensitive skin lining your anus more irritated. That can make farts seem warmer than normal.

Tight pants

If you have on tight underwear or tight pants, the gas you expel from your rectum will likely hover just a bit longer around your bum before it’s dispersed through the fabric.

Hot farts and constipation

Constipation and hot farts can go hand in hand. When your gastrointestinal (GI) system is backed up and you haven’t been able to have a bowel movement for a few hours or days, your bowels have less space for gas. That means you won’t exert as much force when you do fart, which can make the toots seems hotter than normal.

Constipation can be caused by several factors, including:

eating a diet low in fiber

drinking too little water

getting too little physical activity
