Research shows that a new and curious scent can help boost sleep: the scent of a loved one. This smell is both calming and relaxing. The scent of a romantic partner can also help lower stress levels. Studies found women feel calmer after being exposed to their male partner’s scent. Conversely, a stranger’s scent had the opposite effect and raised levels of the stress hormone, cortisol.

So, don’t worry if you are not with your partner for the night, a sniff of their old t-shirt could make it feel like they are right at home with you!

More traditional fragrances that are scientifically proven to promote restfulness and relaxation are as follows:

  1. Lavender
  2. Vanilla
  3. Valerian Extract
  4. Sandalwood
  5. Juniper
  6. Lemon
