Red Light Therapy vs Sunlight: What's the Difference?


Created on:

With modern medicine being so advanced in the present day, it makes sense that we’re constantly looking for ways to improve our health, from the mental to the physical. There are endless ailments or possible injuries that can hold us back from achieving our goals, and it’s important to search for answers. In the last few years, one has been particularly popular for those wanting to heal in the comfort of their own home: red light therapy.

While the general public may not know much about it, RLT is starting to become a real force of nature in the field. Of course, there are uninformed views out there that can always hold you back, with some believing it isn’t too dissimilar to sunlight itself.

Today, we’re here to take a proper look at both and figure out what they can offer you.

Red light therapy and sunlight: what are they?

Red light therapy is a kind of photomedicine that treats you in both a medical and cosmetic way. It sends red and near-infrared light into your cells to promote healing, and no, it isn’t painful or invasive. It can stimulate regeneration, repair your skin cells, and generally speed up the recovery time for an array of different issues you may be having.

Sunlight, in essence, is a part of the electromagnetic radiation that is given off by the Sun on a particularly sunny day. There’s the visual light that you can physically see, infrared radiation that makes you feel hot, and UV radiation rays that can’t be seen or felt. It can most often be found in the summer, but that can vary depending on where you are in the world.

The benefits of red light therapy

There are a plethora of benefits to be found when using red light therapy. It can give you relief from joint pain, reducing inflammation in many different parts of your body. It can also improve your skin condition which includes dealing with anything from scars to psoriasis, spots, and rosacea, showcasing just how all-encompassing it can be.

It’ll assist with getting rid of or improving the appearance of your wrinkles, reducing stretch marks, helping wounds heal quicker, and more. If you suffer from problems such as eczema or arthritis then it’ll definitely be worth giving RLT a try, especially as we continue to see more and more studies proving its effectiveness.

The benefits of sunlight

From a general perspective, sunlight is known for putting a smile on your face and improving your mental health - largely because the brain releases serotonin, helping you feel calm and focused. With that can come improved sleep, settling your circadian rhythms by regulating the levels of both serotonin and melatonin that you possess.

Your body also absorbs vitamin D from the sunlight you receive which can help prevent illnesses, infections, and can generally leave you feeling re-energized at all times of the day. There are even studies suggesting that these positive effects could eventually extend your life expectancy, and what better seal of approval is there than that?

Red light therapy vs sunlight: our final thoughts

The positive impact that red light therapy can have on your life is there for all to see, and the same can be said for sunlight. However, the SPF (sun protection factor) used in sunscreen is absolutely vital for those who plan on spending extended periods in the sun. If you don’t use it regularly, it could lead to an increased risk of long-term health conditions.

As for RLT, you should also be using it in moderation, but it’s been proven safe to use, and that’s certainly the case for our products here at NovaaLab. We offer a variety of different options for anyone from beginners to experts, with our sole intention being simple: to help others gain an even greater quality of life.
