Health Information Which "Bad" Habits Should You Break (and Which Should You Keep)?

Learn how the things you do every day can affect your health.

A smoking habit can harm almost every part of the smoker's body. But doctors — and the smoking public — haven't always known that. Before researchers laid bare the links between smoking and the many diseases it can cause, tobacco companies ran ads that promoted the health benefits of their cigarettes.

"Have you any of those little nervous habits such as twisting your handkerchief ... (or) playing with your ring?" asked one Camel ad from 1934. "These may all be signs of jangled nerves. ... Remember, if you smoke Camels, you can smoke as many as you want, for Camel's costlier tobaccos never jangle your nerves."

This ad, of course, gets a lot wrong. Not only is smoking one of the unhealthiest possible habits; fidgeting — those "little nervous habits" — can actually be good for you.

History suggests, then, that it's not always easy to figure out which "vices" are worth ditching. So Discover Rush Online asked primary care physician Johan Lane, MD, to explain whether we should kick — or embrace — some common "bad" habits.

"Bad" Habits You Can Keep

Fidgeting. Studies suggest that people who make more "incidental" movements — such as repeatedly tapping their feet or getting up to walk to the restroom — have an easier time maintaining their weight and their heart and lung health. "Fidgeting can also be a relatively healthy way to release nervous energy or creativity," Lane adds.

So if you fidget, there's no need to stop. That said, the benefits of fidgeting aren't great enough — and the results aren't conclusive enough — to justify dropping your exercise routine in favor of tapping your fingers on the table.

Double checking. Do you sometimes go back home a few minutes after leaving, just to make sure you locked the door? While they might make you late or annoy your spouse, "these kinds of habits have a self-preserving effect," Lane says. "That one time the garage door really is open, or you really do have lettuce in your teeth, you'll probably be glad you checked."

That said, talk to your doctor if you compulsively check on things to an extent that significantly interferes with daily life, which can be a sign of a psychological disorder.

Drinking (in moderation). Drinking too much alcohol can increase your risk of alcoholism; head, neck, stomach and breast cancers; and risky behavior (which may, in turn, lead to car accidents or sexually transmitted infections).

But small quantities of alcohol can have health benefits, particularly for your heart. One large study found that moderate drinkers were about a third less likely than nondrinkers to have a heart attack.

"The key here is moderation," Lane says. That means no more than one drink a day for a woman and no more than two drinks a day for a man. (One drink equals 12 ounces of beer, 5 ounces of wine or 1.5 ounces of liquor.)

Habits You Should Break

Smoking. Even in the smallest quantities, smoking is bad for you. "Try to quit as soon as you can," Lane says. Many of his patients have succeeded by setting small goals and cutting back gradually before quitting completely.

Think it'll take years for your body to reap the benefits of kicking the habit? Guess again: The benefits of quitting begin just 20 minutes after your last cigarette.

Not exercising. Not all bad habits are as obvious as smoking. "A lot of times we don't think of bad habits as not doing things," Lane points out. "But not exercising is actually one of the most common bad habits."

If you're too busy to go to the gym, you can still get the benefits of exercise by doing it in small chunks. "Exercising 15 minutes in the morning, 15 minutes at lunch and 15 minutes after work is just as good as a continuous 45-minute workout," Lane explains.

Not sleeping enough. Another bad habit by omission, getting too little sleep can have serious health effects. Research has shown that chronic sleep deprivation increases your risk of high blood pressure, diabetes, obesity, depression, heart attack and stroke.

Most adults need seven to eight hours of sleep a night — so you should go to bed early enough to get that much. If you regularly have trouble falling asleep, discuss it with your doctor.

Looking at a screen right before bed. One way to get more sleep? Break the increasingly common bad habit of looking at a screen right before you go to bed.

"We think that light, especially from things like TVs, tablets and smartphones, can affect the hormones that help us to sleep," Lane says. "So I recommend that people don't use these things within an hour or two of going to bed, especially if they have problems with sleep."

Slouching. Screens also sometimes cause us to hunch over them. And routinely hunching or slouching, whatever the reason, can cause low back pain. If you spend all day sitting in front of a computer, stand up every so often (maybe even now) and walk around.
