My favorite light and sleep optimization company BluBlox has rebranded itself as BON CHARGE. They’re now involved with a huge range of evidence-based products to improve your wellness and life in every way. Their extensive range of premium wellness products help you sleep better, perform better, have more energy, recover faster, balance hormones, and reduce inflammation…the list is endless. From blue light glasses to EMF management and circadian-friendly lighting, BON CHARGE products help you naturally address the issues of our modern-day way of life effortlessly and with maximum impact. My favorite products are the red light lightbulbs because they can be used to create a melatonin-friendly environment in your bedroom by shining only red and not blue or green lightwaves that would reduce your sleep quality. After using these red lightbulbs, I find it much easier to fall asleep and feel less awake before bed. Go to boncharge.com/SIIMLAND and use coupon code SIIM15 to save 15%.
