5/ Spice up your space with some seasonal smells.
The scent can affect our mood. Furthermore, that's why the smell makes us happy, and the stench makes us upset. Fragrances are also closely linked to our memories, which is why a warm, wood-scented candle can always remind us of winter. That memory is continuously strengthened, and when you light a scented candle every Christmas, it can evoke your memory.
Try an essential oil diffuser or vaporizer or a scented candle to spread these scents in your home. Different fragrances can have other effects. For example, some odors can energize, some can help relax, and some can help you fall asleep. Change the arrangement of your scent indoors depending on where you live. Some winter-themed scents are ones like nutmeg, cinnamon, vanilla, and lavender.
