Although it seemed quite fantastic in the past, today, science is acknowledging that our minds have a huge impact on physical health. Bodies and minds are very connected and it’s really amazing how the different processes within us can be controlled and stimulated by each of them.

1. Use your non-dominant hand to eat less.

If you can't resist eating at any time of the day, start eating with your non-dominant hand, and researchers say you'll eat less.

2. Apply ice to hand when you have toothache.

This may sound unbelievable, but a study has shown that an ice massage between the thumb and forefinger will reduce toothache.

3. Sleep immediately after studying to learn better.

If you fall asleep right after learning something new, you will remember it better than if you stay awake for a longer time.

4. Chew gum to focus.

Researchers suggest that chewing gum helps you focus longer on tasks that require constant concentration, such as reading.

5. A pencil in the mouth can improve mood.

Try this if you are stressed or in a bad mood. A psychological research project showed that holding sticks in your mouth, in such a way that it looks like you’re smiling, will actually make you happier.

6. Write down your emotions before an exam on a piece of paper to get the best out of it.

Researchers from the University of Chicago believe this may work. To get a better grade, just write about your anxiety and concerns before the exam.

7. Listen with your right ear for a better hearing.

Daily background noise and permanent interruptions can really affect your ability to fully understand what you are hearing. However, one study says that both children and adults hear better with the right ear.

8. Eat on a regular basis even when you encounter flight delays.

We have all tried to delay our flight at least once. Adjust meal schedules, and eat at the same time each day.

9. Divide large projects into smaller pieces to be more productive.

Specialists believe that any task can be much more manageable if you break it into smaller pieces. Then you need to think about the logical order of completing those parts and create a timeline for the realization of each.

10. Start the day with the hardest task to perform better.

We tend to start with lighter and more enjoyable tasks, however, this negatively affects our productivity. One study suggests that we should do the opposite: first and foremost make the task more difficult, so that performance during the day will be better.
