1. ‘Crack’ Your Knuckles
It doesn’t just annoy your friends and co-workers — it may not be very good for you, either. A substance called synovial fluid keeps your joints moving easily. The sound your knuckles make when they “crack” comes when you pop tiny bubbles in that fluid. If you do it all the time, you’re more likely to have swollen hands and a weaker grip over time. It doesn’t seem to raise your chances of arthritis, though.
2. Bite Your Nails
This can damage your teeth as well as the skin around your nail bed, which can lead to infection. You also may get more colds and other illnesses when you put your fingers, which often carry germs, into your mouth. It can help to keep your nails neatly trimmed or manicured. If stress could be the reason for your habit, you might try things like exercise to manage it. Talk to your doctor if you want help stopping.
3. Cheat Yourself on Sleep
If you don’t get enough sleep, you’re not just turning yourself into a daytime zombie — you also could be more likely to have high blood pressure, heart disease, diabetes, and depression. And it might be harder for you to learn and remember things. Set a regular sleep routine and stick with it. And do your best to get 7-8 hours a night.
4. Blast Your Headphones
Sound is measured in decibels — normal conversation is about 60 decibels. It’s best to keep the volume in your headphones below 75 (about as loud as a vacuum cleaner) to be safe. And don’t listen for more than a couple of hours at a time.You’re more likely to lose hearing as you age if you’re around loud noise a lot. That happens with more than half of us by age 75. Hearing loss in older adults is linked to thinking problems and even brain tissue loss.
5. Surf Before Bed
Not waves — the Internet. The “blue light” given off by electronic gadgets like phones, computers, and TVs can mess up your sleep. And some studies show that too much of any kind of nighttime light might be linked to cancer (especially breast and prostate), diabetes, obesity, and heart disease. Calm yourself before bed. If you want to read something, open up a book. Keep your bedroom dark and quiet for better sleep.
6. Sit for Long Periods
Most people spend too much time in chairs. Part of the problem is the modern workplace, where you may hunker over your computer for hours on end. This slows down your metabolism, which means you could gain weight. It’s also linked to other health problems, including heart disease. There’s an easy fix, though: Just get up now and then and move around. Even a 10-minute walk each day can help.
7. Drink Alcohol
Regardless of the researchers supporting moderate intake of alcoholic beverages, you want to save yourself from health challenges such as kidney disease, liver disease, digestive issues, heart problems, bone damage, cancer by stopping alcohol intake
The health risks obviously outweigh the benefits, you may want to consider stepping down on your alcohol intake and stopping eventually.
8. Eat Too Much
If you make a habit of it — even if it’s healthy food — you’re likely to gain weight. That can lead to heart disease, diabetes, and high blood pressure, and it can raise your chances of certain kinds of cancer. Check portion sizes before meals and measure out snacks you have in front of the TV, so you know exactly how much you’re eating.
9. Eat Too Quickly
It can leave you less satisfied — and make you more likely to overeat over the course of the day. If you slow down, you could feel fuller with less, because your body has a chance to realize you’ve eaten enough. It can help to focus when you eat: Take small bites, and chew them well.
10. Skip Flossing
You did a full brush, isn’t that enough? Nope, you need to clean between your teeth, too, if you want to do all you can to get rid of plaque, the sticky bacteria-filled film that causes cavities. Too much plaque also can lead to gum disease, a serious condition that’s linked to other health issues like stroke, heart disease, and diabetes.
11. Eat Junk Food
Soda, candy, and pastries have lots of calories and little nutrition, and all that sugar gets into your blood too quickly. Those kinds of things are linked to serious health problems like obesity, diabetes, and heart disease. “Complex carbs” with more fiber and nutrition — whole grains, fruits, and vegetables — take longer to digest, satisfy your hunger, and give you steady energy. “Good” fats like nuts and seeds also can be part of a healthy diet.
12. Spend Too Much Time Alone
It’s not how many people you know or how often you see them — what matters is that you feel connected to others. If you don’t, you’re more likely to have high blood pressure, depression, brain issues (like Alzheimer’s), and inflammation. If you feel alone, reconnect with family or friends, or start something new that involves other people — join a book club or learn to play tennis or bridge, for example.
13. Smoke Cigarettes
This bad habit affects nearly every organ in your body. It can lead to heart disease, cancer, diabetes, stroke, bronchitis, emphysema, and other health problems. It also raises your risk of tuberculosis, eye problems, and immune disorders like rheumatoid arthritis. And if you spend a lot of time around someone who smokes, you’re more likely to have asthma, heart disease, lung cancer, or a stroke. Talk to your doctor about quitting smoking.
14. Go to a Tanning Bed
Even though this is not common in our environment, it is worthy to note considering the rate at which we are adopting western lifestyles.
A tanning bed is a piece of equipment with ultraviolet lights. You lie on it to make your skin browner. It predisposes to skin cancer.
