Lose your double chin! Straighten your teeth! Get a jawline so well-defined you could open a bottle of beer on it! These are just a few of the supposed benefits of 'mewing', an odd but popular practice of DIY facial reconstruction - no cosmetic surgery required.
Originally conceived by a controversial orthodontist, the technique has become a viral beauty trend on social media platforms.

HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?
Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys.
