How can I get into light therapy?
Light therapy has long been used by athletes and fitness trainers to increase recovery and reduce oxidative stress. These days, it’s fast becoming a regular at the local gym and Wellness Spa too. You will probably be able to find bright light rooms or “red light stations” there, which form part of the hot and cold cycle of rejuvenating treatments alongside the cold panels and saunas.
Having easy access to light therapy doesn’t stop there. On the Internet, you will find many products that sell Red-Light Therapy beauty tools for home use. Red treatment options include face masks, massage guns, blankets and panels, and bright red revitalizing hats that stimulate hair growth.
For example, Theragun Pro Plus offers five treatments combined in a full area with this warm body figure that shows LED light and vibration to give you 15 minutes of exercise in two minutes.
Prices and effectiveness vary by brand name, design, and quality. A cheap mask may not work to reduce fine lines and wrinkles and you’d like, but at least you’ll look like you’re preparing for a trip with the new bezos.
Benefits of light therapy
In the age of BOTOX Naisler and plastic surgery plastic knives, the light treatment is closure. It uses specific wavelengths of red and red light to stimulate cellular activity and help them heal properly. “Red light therapy is an umbrella term that includes all the red light funks on the spectrum, from the basic visible LED led to the illegal transparent light of the laser,” said Graeme Glass, director of beauty at LYWA.
“These specific wavelengths that look red are visible very bright and very close – they can stimulate cellular activity and support the processes of repairing the body’s conditions. Mitochondria (battery packs (cells) manage briefly as they were young.”
RLT has been shown to rejuvenate the skin to improve texture and tone, reduce wrinkles, and aid in recovery, for example. It has been shown to help after exercise to give muscles more energy to repair and function, reduce joint stiffness, increase circulation and increase energy levels. There is evidence that the frequency of red light can help regulate circadian rhythms, calm the mind and induce sleep. But remember, these are controlled studies using lab-grade equipment, so home devices may give you different results.
