Working Out

How it Works

blö is a cross between a fan and an air conditioner. It uses a small motor and a blade to create airflow, but it doesn’t work like a typical fan. It draws air in through a chamber where it passes over peppermint oil which acts as the cooling agent. You don’t have to use the peppermint oil, it just enhances the cooling sensation and cools you off much quicker.

The cooler air flows out of the bottom and sides and focuses on a small area of your skin at a targeted location. Unlike a fan that tries to get maximum airflow, blö cools off a small portion of your body using ambient cooling, similar to how an ice cube cools you off. Once that area gets cold, the rest of your body adjusts and you get cooler. When you combine that with the effects of peppermint oil described below you get the perfect combo to cool you off quickly.

How Peppermint Oil Cools You Off

The receptor protein that senses change in temperature is called TRPM8 and is found in all cold sensing nerves. The menthol in peppermint oil binds directly to TRPM8 and activates it which allows the body to feel cooler. Ref: 1.

We combined ambient cooling and TRPM8 activation with targeted locations on the body to create a maximum cooling effect.

Ambient cooling + TRPM8 activation + Targeted locations = Maximum cooling

blö was designed so you can attach it to your clothing at natural cooling locations on your body.

The Brain Stem Regulates Body Temperature

The area of the brain that senses and regulates body temperature is located at the base of the neck in an area known as the brain stem.
blö was strategically designed to be placed at the base of your neck to cool you off faster. When you cool this area down the rest of your body becomes cooler.

blö works just as well when positioned on the front of your body or on your lower back.

Essential Oils

blö not only cools you off, but it also allows essential oil users to enjoy the health benefits of their small diffuser on the go.

Peppermint oil makes the air feel much colder. Not only that, it smells great too and has healing properties!

Essential oils belonging to the mint family, especially those with higher percentages of menthol, like Peppermint Oil, will help make the body feel cooler. Menthol has the ability to trick receptors in the brain into thinking that the body is cooler than it really is. Ref: 2

We also recommend using lemongrass essential oil. It both repels mosquitos and relaxes you at the same time, but you can add other oils as well.

The cool thing about blö is it is designed so you can add whatever essential oils you want depending on your preference. The possibilities are endless!

Inhaling the fragrance of essential oils benefits the sympathetic nervous system. Inhalation of essential oils has shown a decrease in blood pressure and can be used to regulate dysfunctions of the sympathetic nervous system. (Haze, et al. 2002) Ref: 3
