There are numerous reasons why you should keep your ring on your bedside table at night. For one thing, while you're catching ZZZs, your ring may become entangled in your hair or mattress, loosening the setting. 

Certain sleep postures might apply pressure and body weight to your ring, gradually reshaping the setting or loosening the stones.

It may be an especially good idea to temporarily part with your piece while sleeping if your ring consists of stones on the softer side of the Mohs scale.

In some case, you may experience discomfort from nighttime swelling and the resulting ring tightness.

Besides removing your military ring when you are going to sleep, you also should remove your ring when under several situations such as:

When swimming

You must have heard many horror stories about diamond rings getting lost in the ocean. Due to this, it would be unwise to wear them while spending the day at the beach.

Swimming (especially in cold water) can lower your body temperature and shorten your finger size, making it much easier for your ring to slip off.

Salt water is a ring adversary that can form a film. The pool is also off limits. Chlorine and other chemicals in pools degrade certain ring materials and metal alloys.

In white gold wedding rings, the rhodium will deteriorate in chlorine, turning them yellow. Whether you're heading to the beach or the pool, make sure to store your ring at home first.

Don't set it next to a towel or in a beach bag. While one dip in the water is unlikely to damage your ring, it is preferable to keep it safe at home.

When doing yard work

You should wear rubber gloves when handling cleaning supplies to protect your hands, so keep your ring away from the abrasive, harsh chemicals found in popular household cleaners.

Bleach, for example, oxidises metals.

Remember this mantra: what makes your bathroom mirror shine, dulls your diamond ring. The same is true for gardening, which necessitates a variety of tasks that can endanger (or dirty) your ring.

When cooking and preparing food

This usually goes without saying, but it's easy to overlook: remove your ring before handling any raw or ground meat.

The last thing you want is for your ring to become bacterially contaminated.

Though you may clean your ring on a regular basis, it might still store bacteria that can be transferred to or from the food you're cooking.

Sharp kitchen knives, hot ovens, and stovetop stresses can all put your ring at risk, so remove it when you're in the kitchen.

When operating machinery

Many forms of machinery can be detrimental to jewelry and even dangerous, depending on the equipment in use. If you're using machinery for work, a pastime, or any other reason, consider removing any rings and jewelry to guarantee optimal safety.

This can also apply to equipment used for home-based activities. When in doubt, read the safety instructions for the equipment you're using for any mentions of jewelry removal before you begin working.

When applying lotions

One of the most common causes of dull diamond rings is buildup from lotions, moisturizers, sunscreen, oils, and other beauty products. Make it a part of your beauty regimen to store your ring carefully when using moisturizers and other cosmetic products.

Don't put it back on until you've finished doing your hair. Otherwise, it can easily snag, which, in addition to making you uncomfortable, can help to loosen the setting.

In addition to this, lotions and cosmetics have the potential to damage certain gemstone engagement rings. So, you should keep them out of your rings.
