How many times have you been told as a child to stop biting your nails, picking your nose or cracking your knuckles? It turns out all those and many more ‘bad habits’ are actually good and beneficial for our health.

1. Cracking Your Knuckles
The arthritis warnings surrounding cracking your knuckles are misguided and misinformed at best. Scientists explain that synovial fluid present in your joints acts as a lubricant. The fluid contains the gases oxygen, nitrogen, and carbon dioxide. When you pop or crack a joint, you stretch the joint capsule. Gas is rapidly released, which forms bubbles. In order to crack the same knuckle again, you have to wait until the gases return to the synovial fluid. The process can relieve joint and muscle tension and is very similar to the therapeutic techniques practiced by Chiropractors. In a large study following people that did and didn’t crack their knuckles over a five year period found that knuckle crackers’ joints were just as healthy as those who didn’t. Cracking your knuckles is actually healthy for your joints, giving you more flexibility and movement.

2. Nail Biting
Biting your nails can actually boost your immune system! Chomping on your nails exposes you to trace amounts of microorganisms that can make you sick. When a bug is encountered a second time, the immune system reaches into its memory and releases weapons — called memory lymphocytes — that it knows will beat it. So, regular nail biting exposes us to small amounts of potentially immune-boosting bugs.

3. Nose Picking
The same principle applying to nail biting also applies to picking your nose and consuming the result. Professor Dr. Friedrich Bischinger, a lung specialist in Austria, says picking your nose and eating it is healthy for two reasons:
i) With the finger you can get to places you just can’t reach with a handkerchief, keeping your nose far cleaner.
ii) Eating the dry remains of what you pull out is a great way of strengthening the body’s immune system. The nose is a filter in which a great deal of bacteria is collected, and when this mixture arrives in the intestines it works just like a medicine.
Although it won’t harm you, you may be a social outcast if done in public so consider it as a private practice.
