For deeper tissue benefits, you can get a little closer. It is recommended to be 20cm from the device for a treatment time of 5-10 minutes. This allows the light photons to penetrate deeper and reach some of your muscles and organs, allowing the beneficial healing power of red light to take it's effect. Remember, the closer you are to the light, the higher the intensity. Therefore applying Mercola's formula you will need less time in front of the light to achive the required amount of energy from it.
At 15cm the Half Stack achieves a light intensity of around 100mW/cm2. In theory, you only need 1 minute to achieve the 6 Joules of energy, but given the depth you are targetting, it is recommended to apply the similar treatment times of 5-10 minutes.
You can use red light as a 'pre-workout', and use it up to 1 hour before your workout to stimulate bloodflow and energy for your muscles. You can also use it post working out, as the increased nutrient delivery and energy generation within you mitochondria and cells, means you will recover faster and experience less DOMS (Delayed Onset of Muscle Soreness).
Therefore, in summary in order to target the deeper benefits of red light for muscles and organs:
- Stand a little closer to the light, at 15-20cm
- Treatment times are reduced as the light photons are stronger, therefore these should be 5-10mins
- You can use as a pre-workout, or post workout to maximise recoovery, so you're ready for your next session
- You will still be getting the skin health and other benefits of using red light therapy using the above protocol
Whatever goal you are targeting, you will still receive all the other benefits to do with red light therapy during your treatment (see our blog post on Which Wavelengths Work).
You should also feel the gentle warming effect on your body which is natural as red and near-infrared light improves blood circulation and mitochondrial energy and efficiency.
Don’t worry though, the lights never get hot enough to burn you or damage your skin.
