A phone, wallet, keys and a few small essentials disappear into our pockets almost automatically before we leave home.

Most of the time, that is exactly where they belong. But a few common pocket habits can create problems that range from discomfort and accidental calls to damaged batteries or exposed personal information.

Here are five worth checking.

Sitting on an overloaded wallet

A back-pocket wallet can slowly grow thicker with old receipts, unused cards and loose cash.

Mayo Clinic says sitting on a large wallet can tilt the pelvis and compress the sciatic nerve, potentially causing pain or numbness in the hip or leg, especially during long periods of sitting or driving.

Better habit: Remove a bulky wallet before sitting for extended periods and clear out what you no longer need.

Carrying loose batteries with keys or coins

A spare battery should not be tossed loose into a pocket filled with metal objects.

Health Canada specifically advises keeping batteries away from keys and coins and out of pockets, purses and bags unless they are properly protected. Contact between battery terminals and metal can create a short circuit, leading to overheating and potentially fire or explosion.

Better habit: Carry loose batteries in a protective, non-metallic case.

Keeping unidentified pills loose in a pocket

A tablet slipped into a pocket in the morning can be difficult to identify several hours later, while heat and storage conditions can also matter for some medicines.

Health Canada recommends keeping medication in its original container, storing it in a cool, dry place and avoiding mixing different medicines together. Canadian travel guidance also recommends keeping medication in its original labelled packaging when travelling.

Better habit: Keep medication identifiable and follow the storage instructions provided with the drug or by your pharmacist.

Carrying sensitive documents you rarely need

The contents of a lost wallet can be more valuable than the wallet itself.

The Government of Canada advises people not to routinely carry their Social Insurance Number card or confirmation letter in a wallet or bag. Limiting access to the SIN helps reduce the risk of fraud and identity theft.

Better habit: Carry only the personal documents you actually expect to need that day.

Letting your phone operate inside your pocket

Pocket calls and accidental messages still happen when a phone screen responds to unintended touches.

Some smartphones include features designed specifically to prevent this. Samsung, for example, says its Accidental Touch Protection feature keeps the screen from responding to unintended taps or swipes in dark places such as a pocket or bag.

Better habit: Lock the screen before pocketing the phone and enable accidental-touch protection when your device offers it.

None of these items is unusual.

The difference lies in how we carry them.

A quick check of what goes into your pockets each morning can prevent unnecessary discomfort, protect personal information and eliminate a few everyday problems before they start.
