1. Reusing unwashed grocery bags

The problem: Reusable grocery bags reduce waste. But they may also harbor germs that could contaminate your food and make you sick.

The fix: Wash reusable bags frequently. Put cloth ones in the washing machine, and scrub plastic ones with hot, soapy water. Store in a cool, dry place.

2. Eating large amounts of nuts

The problem: Nuts are packed with protein, fiber, vitamins, minerals, and heart-healthy fats. But they also contain about 160 to 180 calories per ounce.

The fix: Keep servings small—1.5 ounces (a small handful) of whole nuts or 2 tablespoons of nut butter.

3. Counting sheep for hours

The problem: A consistent bedtime helps promote better sleep. But if you don’t doze off within 20 minutes, forcing yourself to stay in bed is counterproductive.

The fix: Get up and do something relaxing, such as reading a book or listening to soft music, until you feel drowsy.

4. Doing the same workout every day

The problem: Staying active is crucial for your health. But always doing the same thing can get boring and zap your motivation.

The fix: Mix things up. Walk one day; then ride your bike, go for a swim, or use an elliptical machine the next. Include strength and flexibility activities as well.

5. Leaping before you look

The problem: It’s fun to try out a new cardio routine, strength move, or yoga pose. But improper form could lead to injury.

The fix: To see how to do an exercise correctly, take a class, follow a video, or look up how to do it online.
