Crussh and healthy lifestyle app, Lifesum offer the first Seasonal Affective Disorder experience to help Londoners beat the winter blues

The ‘Blues Beater smoothie’ and light therapy boxes provide Londoners with an essential vitamin D dose during the dark winter days

This January,  we have been busy working on a new and exciting project: a collaboration with healthy lifestyle app, Lifesum and the SAD Lightbox Company. The UK’s National Health Service estimates that one in fifteen people experience Seasonal Affective Disorder (SAD)  symptoms each year, which include depression, fatigue, and decreased concentration.

Lifesum, being based in Sweden, knows all too well about the long periods of Nordic winter darkness. With an average of seven hours of sunlight in January, nutrients play a vital role in the physical and mental well-being of the population.

Data collated from the Lifesum app showed that many of Lifesums users in the UK lack vitamin D, which is essential for fighting winter blues. So, in order to help Londoners fight SAD, we\’re launching a ‘Vitamin D Pop Up’ in the heart of the capital on Blue Monday (January 16 2017 –  reportedly the most depressing day of the year). The bar will offer SAD lightboxes for people to use, along with ‘Blues Beater’ smoothies – Co-created together with Lifesum to help you raise your vitamin D and serotonin levels.

The smoothie, available in all 27 Crussh stores across London, has the following key components:

  • Kefir by Bio-tiful
  • Vitamin D booster
  • Blueberries
  • Spinach
  • Banana

Kefir, a fermented milk drink made using kefir ‘grains’, adds a natural protein and calcium hit as well as being packed with billions of gut friendly bacteria. Also high in magnesium, fibre and protein, the smoothie speeds up the body’s metabolism and ability to absorb vitamins.

Customers visiting our New Street Square store (5-7 Nevill Lane, New Street Square, EC4A 3AP) will be able to fight the symptoms of winter blues even further by spending time in front of a dedicated lightbox, provided by the SAD Lightbox Company. These SAD lightboxes will be available for two weeks.

So, don’t let the January blues get you down, just grab yourself a Blues Beater smoothie and relax in front of a light therapy box, summer will be here before you know it.
