HOW DANCING CAN IMPROVE YOUR MENTAL AND PHYSICAL HEALTH Move your body to your favourite tunes – it’s the ultimate feel-good exercise and has some surprising effects on both the body and mind Music and dance have been fundamental parts of the human experience for thousands of years. No matter what your favourite tune may be, music can have a huge effect on your wellbeing – Charles Darwin even thought that our ability to make and understand rhythmic beats worked as an early form of communication. Whether or not we still share messages through music, we all know that it can change our mood and studies have shown that we share a natural sense of rhythm (no matter how much you might protest). Dance is therefore a natural outlet, and one which can do a lot to make us feel good. Club Azucar offers corporate dance packages for the workplace in order for your organisation (Companies, Institutions & Schools) not only function at its best, but to be happy and healthy in life. These are the expected benefits for the individual employee which have been also confirmed by the participants: Physical Health: Salsa/Zumba or any Latin Dance Classes improves mobility, coordination / motor skills and fitness level.while being a low-impact exercise which includes people of all ages, abilities and fitness levels Mental Health: Dancing requires full concentration so for one hour away from their desk ,participants will experience reduced stress levels, , feel refreshed and more alert and able to concentrate better following the lesson Music in combination with physical exercise has an uplifting effect through the release of endorphins and dopamine in the body & brain Learning a new skill is proven to train your brain, contribute to prevention of dementia and give the confidence to face new tasks and challenges in other areas of work and life The patience and encouragement of the teachers has furthered this new confidence and sense of achievement and contributed to participants’ belief in themselves and their ability to take themselves out of their “comfort zones” and take on new challenges Getting to know each other in a social rather than work context and learning a new skill together, dancing and laughing together, gives participants a sense of belonging and furthers team buildingDo you want more proof?
