Now that we're into September, it's time for many telltale seasonal changes to take place. Shifts that not only remind us that it's fall, but that lead toward a new season and changing weather. For instance, candle scents, beverage flavors, and even the colors of clothes that we wear. Some of these go-to fall sessions are recognizable nationwide (maybe even beyond), while others might indicate personal choices come fall. Whatever the changes, however, it's how you prep for cooler temperatures – in both practicality and preference.

In any instance, how do these common fall signs affect us? And should we be looking to change them for the better?

Common Fall Fare:

Apple Cinnamon Candles

These pie-themed candles are all the rage with fall weather. As are pumpkin, nutmeg, and other "fall" scents. They can also be found frequenting houses all across America. Whether they're lit and hosted on top of a counter, wax that's placed in a lamp-heated device, or released into the air by an alternate substance, like aerosol or scented oil. No matter the form of technique, however, we all want to know the same question: are they safe? Yet the answer isn't as clear as we'd like – it simply depends on what you're dealing with. In general, aerosol fresheners release toxins, as well as their scents, into the air. While lit candles bring burning chemicals into your breathing space. In contrast, heated waxes and perfumed oils are much safer for the nose and lungs. Be sure to check labels to be doubly sure, as each brand might be laced with a different recipe.

Pumpkin Spice Lattes

Even the regular coffee drinkers will sway from their order to indulge in this delicious concoction. It's a seasonal blend that smells as great as it tastes, but can only be purchased for a few months out of the year. (To avoid that ill fate, many pick up special creamer or ask a small-town coffee shop to mix their own brew.) But what about how this cult classic affects the body? Obviously, it's not good to ingest too many lattes, no matter what flavor. Especially when adding in whipped cream and all the sugars that come standard on pumpkin spice. It's also a good idea to count caffeine intake, as too much can cause unwanted and severe consequences. (The same goes for artificial sweeteners or flavorings, though caffeine comes in higher amounts in these beverages.)

Potpourri

Similar to the candles listed above, there's just something about potpourri that screams fall. What's nice about this decorative piece, however, is that it's fairly gentle in reach (unlike some other room-freshing methods), and can be adjusted for individual tastes. It's also an easy DIY project that doesn't require any type of waxes or oils. Whether cooking or purchasing, however, pay attention to what's included all around. Some natural ingredients can cause allergies (or bring in critters if not properly prepped), as can certain scent additions. Be sure to use mild ingredients and admire potpourri from afar to keep each batch as safe as possible.

The Great Outdoors

Let's face it, outside smells "different" with each weather change. Yet out of all the seasons, fall likely smells the best. There are plants changing colors, winds blowing in cooler air, and a brisk feeling – all of which band together for Mother Nature's own personal pre-winter scent. Many of us even open our windows so we can enjoy it inside as well as out. But is it safe? So long as you aren't letting creatures inside (especially the tiny ones who like to hide), or are susceptible to fall allergies, generally yes. Opening windows can land triggers within fabrics, allowing them to affect you for months at a time. If you might be susceptible leave the windows closed instead.
