Yoga is an open-source, customizable, and innovative creative practice with many forms, shapes, and colors. Smiley Retreat likes to see it as a great methodology for controlling emotions, calming the mind, and getting closer to your true self, as well as having a multitude of physical benefits and being awesome.

Strengthen the body through five days of coconut water and 1 green juice fasting. Fall in love with yourself a little more! Heal and repair the gut, boost the immune system, lose some fat, let your inner glow shine, and gain a more positive outlook on life. Let go of worries, stress, and negative emotions, leave with a calmer mind and a bigger soul.

Benefits of fasting include:

  • Space and time to heal and repair the digestive system
  • Good against oxidation
  • A boost to the immune system
  • Normalizes insulin levels, improve insulin sensitivity, and regenerates pancreatic cells
