Back in the day, before electricity was a thing — let alone smartphones — humans typically rose with the sun and went to sleep after it had set. This occurred for centuries, and as a result, the human body evolved in such a way that its circadian system ran parallel to the sun.
Essentially, when the sun was up, you woke up and went about your business. And once the sunset for the night, you were tired and so went to sleep. This is evident in the way we biologically respond to light to this day.
Red and Blue Color Light Therapy
Blue light, typically found in the sun, stimulates cortisol and a reduction of melatonin. Cortisol, in particular, is increased when you first awake in order to make you alert. In primitive times, this was in response to the need of being immediately aware of your surroundings in the event danger was nearby. Hopefully, there’s less of a need for that now. Today, cortisol works to get you out of bed and on the road to be on time for work.
Red light, on the other hand, is a spectrum of light that can be found in campfires, for example. It has a profound effect on melatonin levels as it drastically increases the production in your system. Today, melatonin is often sold in pill or liquid form at the pharmacy, marketed as a natural sleep aid. However, exposure to the right spectrum of red light is actually the most natural way to kick-start the existing melatonin in your body.
Artificial lighting and the use of blue light in smartphones, laptops, and TV screens cause our sleeping patterns to be disrupted. Studies have shown that it’s imperative to turn off any blue-lit device 30 minutes before bed in order to have a fair chance of falling asleep. Alternatively, most newer smartphones have a night time function, switching the backlight on your phone to a red hue.
Benefits Of Blue And Red Light
Light can be used for numerous therapeutic treatments. Blue light, for example, is excellent for maintaining physical and mental health, although its benefits are most effective during the day. Blue light enhances your mood and level of awareness.
Additionally, it can signal your body to maintain a certain weight as well as keep your adrenal functions working properly. When blue light penetrates the skin it kills certain bacteria by shutting down the bacteria’s metabolism, which starves and then kills them. This method has become highly reputed through photo facials in order to diminish, and in some cases completely get rid of, acne for those who suffer from severe cases.
Similarly, red light can have just as much of a profound effect on the body. Contrary to blue light, red light promotes collagen production, which can help heal wounds as well as reduce sunspots and hyperpigmentation.
Making Light Therapy Work For You: IPL
Intense Pulsed Light (IPL) is a treatment commonly used for sun damage, hyperpigmentation, rosacea and other skin problems. IPL utilizes light therapy to remove or reduce problem areas. During the 30-minute session, a certified aesthetician will repeatedly pulse either blue or red light over the problematic areas in order to penetrate your skin.
The goal of red light therapy is to tighten collagen and blood vessels that rest in the epidermal layer. This tightening results in a decrease of redness on the skin as well as a reduction in age lines. On the other hand, blue light therapy is primarily used to deal with severe cases of acne and other bacterial skin conditions.
The procedure is quick and doesn’t require any downtime, therefore you can schedule an appointment during your lunch break or right before a night on the town. Better, the treatment is relatively painless as there are no harsh products utilized or exfoliation done to the skin.
If you’re considering an IPL treatment, you can expect the results to last around five years. This treatment will produce different results for everyone. It is highly dependant on the individual’s skin to work to its full potential. It is also recommended to do follow-up treatments every once in a while. Also, stick to a consistent skin care routine in order to maintain your glow.
Light Therapy At No Cost
If you’re skeptical about the effectiveness of light therapy, try making a few simple adjustments to the light. Take small steps like changing the light settings on your devices at night to see if it helps your sleep pattern, or go for a walk in the bright sun to test the effect it has on your energy levels.
