It's easy to minimize the daily impact of lifestyle choices, but medical professional say that many common everyday habits are harming your health. Things like a nightly glass of wine, long days at your desk, or skipping your workout might feel like they're not a big deal in the moment, but these habits can have significant consequences down the road. Certain cancers, heart conditions, and other chronic diseases have been linked to habits like drinking alcohol, not eating a balanced diet, and not exercising enough.
While it's probably unrealistic to change all your habits overnight, understanding the risks of some common habits can help you make better choices. Here's what doctors want you to know about the everyday habits that are harming your health.
Drinking alcohol, even in small amounts
Any amount of alcohol increases overall health risks, including cancer, according to hematologist and medical oncologist Sanjay Juneja, MD. "It’s a common myth that only heavy drinking is harmful, but even moderate drinking has been linked to increased risk, particularly for breast cancer," says Dr. Juneja.

Not eating enough fruits and vegetables
Dr. Juneja says that a diet lacking in plant-based nutrients can negatively impact your gut microbiome, which plays a key role in immunity and overall health.
"Fiber, in particular, supports digestion, reduces inflammation, and helps protect against chronic diseases," he adds.
Occasional smoking
Smoking is a major risk factor for multiple types of cancer, including lung, throat, and stomach cancer, as well as chronic disease.
"There's no 'safe' amount of tobacco use; even light or social smoking can cause lasting damage," says Dr. Juneja. "This includes hookah as well—if not worse."
Ignoring snoring
Snoring may seem harmless or cute in kids, but it is a symptom of obstructive sleep apnea, according to Tonia Farmer, MD, board-certified otolaryngologist and chief medical advisor to Nampons.
"This is a condition linked to high blood pressure, heart disease, stroke, and even sudden death," she explains.
Consistently using nasal spray and decongestants
"Frequent use of decongestant sprays such as Afrin or Neosynephrine can cause 'rebound congestion,' where the nose becomes more stuffy the longer the spray is used or stopped abruptly," says Dr. Farmer.
"Instead, I'd recommend using a nasal steroid like Flonase or Nasacort."
Sitting for prolonged periods
Do you work a standard nine-to-five desk job? Well, you might be sitting for too long.
"Sitting for eight or more hours a day is linked to poor cardiovascular health and an increased risk of obesity," says Dr. Jennifer Brown, MD, board-certified obesity medicine doctor at MyObesityTeam.
"Even short periods of standing or walking during the workday significantly improve overall health."
Not sleeping enough
Chronic sleep deprivation isn't just about feeling tired.
"Poor sleep quietly drives up blood pressure, worsens insulin resistance, and significantly increases stroke and heart attack risk," says Lily Johnston, MD, vascular surgeon with Scripps Clinic.
Skipping annual doctors appointments
According to Dr. Johnston, avoiding checkups and screenings means conditions like high blood pressure, high blood sugar, and abnormal cholesterol go undetected for years.
"These 'silent killers' don't cause symptoms at first, but they're quietly damaging your arteries and can show up later as heart disease, stroke, or peripheral artery disease (PAD)," she tells Good Housekeeping.
Regular preventive care catches these problems when they're most treatable, long before they become emergencies.
Using single-use plastics
Do you drink water from bottles often? You may want to think twice next time you pick up a bottle.
"Not only are single-use plastics detrimental to our environment, but they can also be harmful to our health," says Dr. Brown.
"Microplastic particles accumulate in our bodies, including the brain, so it's best to opt for glass food storage containers and stainless steel reusable water bottles."
Drinking sugary beverages
According to Dr. Brown, one of the most detrimental habits a person can develop is the routine consumption of sugary beverages, including sodas, energy drinks, and fruit juices.
"Sugary beverages are packed with empty calories that do little to curb appetite, and can lead to chronic diseases such as diabetes and obesity," she says.
"It's better to stick with plain water as much as possible."
Ignoring hearing changes
If you find yourself constantly asking someone to repeat themselves or having to raise the volume, then you don't want to put off getting that checked out.
"Ignoring early signs of hearing loss can delay treatment, strain the brain, and increase the risk of social isolation and cognitive decline," says Dr. Farmer.
"Studies have shown that unaided hearing loss can increase the risk of dementia."
Not exercising enough
In today's busy world, many people skip exercise because they don't feel like they have time, but physical activity and exercise are critical to maintaining health.
"Taking the stairs and parking at the far end of the lot are ways to get more steps into your day," says Dr. Alex McDonald, MD, family medicine doctor and assistant professor of clinical science at Kaiser Permanente Bernard J. Tyson School of Medicine.
