I’m a doctor — here are 4 things I would never do because they’re bad for your body

She’s giving her TikTok followers the 4-1-1 on four bad habits to avoid.

Dr. Jess Andrade, a sports medicine specialist and pediatrics doctor in Massachusetts, is sharing the four activities she won’t do — vape, pull an all-nighter, exercise for less than 150 minutes a week and consume too many artificial ingredients and preservatives.

To prove her point, Andrade showed a picture of popcorn lung — the nickname for bronchiolitis obliterans, a lung condition that makes breathing difficult because of damage to small airways.

Johns Hopkins Medicine reports that the culprit is diacetyl, a chemical that was widely used to give popcorn its buttery flavor. Now it’s added to the liquid in some flavored e-cigarettes to evoke a buttery or creamy taste.

It seems that some teens are already taking Andrade’s advice to quit vaping .

Data from September shows that 1.63 million US middle and high school students (5.9%) reported using an e-cigarette in the past 30 days compared to 2.13 million (7.7%) in 2023.

This is good news since besides bronchiolitis obliterans, vaping can cause lung cancer , organ damage, heart disease , asthma, breathing problems and other conditions.

“Pulling all-nighters or not sleeping for 24 hours — the same as being legally drunk,” Andrade wrote in her June post.

Driving with a blood alcohol concentration of 0.08% or more is considered driving while intoxicated.

Being awake for 17 hours mimics a BAC of 0.05%, according to the Centers for Disease Control and Prevention . The CDC says being awake for 24 hours is similar to having a BAC of 0.10%.

Experts recommend getting seven to nine hours of sleep a night. A study published this week finds that the effects of a restless night can linger on our brains for days.

In the long term, poor sleep has been linked to a higher risk of diabetes , heart disease , high blood pressure , anxiety and other chronic health problems.

According to the Physical Activity Guidelines for Americans , adults should aim for 150 minutes of moderate-intensity physical activity and two days of muscle strengthening a week.

Andrade said not reaching that threshold raises your risk of several diseases including heart disease, Type 2 diabetes , colon, breast and uterine cancers, along with obesity, high blood pressure and stroke .

Artificial ingredients and preservatives are often found in processed foods — the bad apples in a diet.

Eating too many ultra-processed foods can lead to obesity, diabetes, depression , heart disease, heart attacks, stroke and high blood pressure.
