It is important to get rid of any bad smells, the odor of last night’s burned roast does nothing good for anyone, before adding new ones.
So open windows, clean, etc. as required before visiting the scent aisle at your local store.
For mingling, a good smell to add is lavender, it’s relaxing to smell and sniffing its odour has been tied to trusting other people more. An odour to which you or your guests have a positive attachment, for example, the vanilla smell of your common grandmother’s holiday cookies, is also, always, a good option.
Generally, however, florals are safe choices. Any scent used should be used in slight, very slight, sparing amounts.
Meeting and mingling pleasantly and regularly are vital for our wellbeing, they are at the core of our humanness.
Meeting and mingling effectively is more likely when the findings of design-related neuroscience studies are applied.
