The Relationship Between Red Light Therapy and Mood Boost
Red light therapy , utilizing a cold source of therapeutic visible red and near-infrared light in the 660–850 nm wavelength range, offers notable health benefits. It's worth exploring red light as an aid in a wellness lifestyle to enhance focus, drive, and self-assurance. The chemistry triggered by red light therapy not only improves physical condition but also significantly impacts mood and confidence. Red light bathing uses natural light to allow cells to produce more energy. Our cells need natural light for power to function, just as they need other nutrients from water and food. Phototherapy based on visible red light dramatically impacts the body's essential metabolic function and the secretion of certain hormones in the body.
Red light can effectively stimulate the feedback and regulation of the hypothalamus and pituitary gland on the brain, maintain the balance of hormone levels in the body, and enable the human mitochondria to promote further DNA/RNA and protein synthesis, ATP decomposition, cellular enzyme activity, improve blood circulation, and promote metabolism in the body. Studies showed red light therapy stimulates the body to secrete endorphins (serotonin and dopamine) – a natural analgesic similar to morphine, which brings pleasure and is also known as the "happy hormone." These endorphins make us feel happy and satisfied when we are running in a low mood, and this positive emotional state is beneficial for confidence. As mood improves and the mental state becomes more relaxed, so does self-confidence.
Red Light Therapy Reduces Stress
The inevitable stress of daily life can seriously affect the mind. A 2012 Yale University study showed that chronic stress can reduce brain volume. If you're in a constant state of tension, your brain may shrink, which can lead to cognitive impairment and mood disorders. Red light therapy is visible and perceptible and can have a crucial impact on psychological well-being. The human eye is the most important sensory organ, and nearly 90% of the information obtained by humans from the outside world needs to be collected and transmitted through the eyes. Through red light therapy, we can lower stress-related chemicals in the brain, such as cortisol, and increase serotonin. When stress is reduced, people tend to be more relaxed and positive, and their self-confidence increases. Red and near-infrared light were able to relieve stress-induced depression in 6 out of 10 participants in as little as four weeks of treatment. Experiments have proven that red light can relax tense nerves, relieve pressure in the brain, and eliminate chronic fatigue.
Red Light Therapy Regulates Sleep
Self-confidence isn't always a mental game. Sometimes, the best way to build confidence is to take care of your body. Several studies have highlighted the relationship between two critical variables: self-confidence and sleep. The researchers showed healthier sleep cycles increased participants' self-confidence and optimistic mindset. A good night's sleep is also essential for a high-quality mind. Red light therapy assists in improving sleep quality by regulating serotonin levels and promoting a natural circadian rhythm. Studies have shown that the shining red light can assist in falling asleep faster and deeper. People with good sleep are likelier to perform better in life and have higher concentration and positivity.
Red Light Therapy Energizes Mind
Red light therapy with deep penetration ability offers potential benefits to enhance cognitive performance, including attention and memory. It stimulates neuroplasticity and supports nerve tissue regeneration by increasing ATP supply and the release of growth factors. Studies show red light therapy may protect the brain from damage and improve memory. It regulates the secretion of neurotransmitters such as acetylcholine. Acetylcholine, a substance in the brain, is deeply related to human cognitive function and motivation. The brain becomes more sensitive to negative responses to external stimuli if our cognition is relatively chaotic.
At the same time, red light therapy modulates the amygdala of the brain to regulate depression, maintain emotional stability, effectively relieve fatigue, relax the body and mind, and allow normal body operation.
Safety of Red Light Therapy
Regarding the research on the safety of red light therapy, experimental data demonstrated that, unlike drugs, red light does not remain in the body and has no residual effects. It is a low-level light energy that is non-invasive and clinically tested. Therefore, as long as the wavelength and intensity of the light source are appropriately selected, it is safe for use.
To sum up, the psychological benefits of red light therapy for mental health are all-encompassing. Not only can red light boost our mood and self-confidence, reduce stress, and improve sleep, but it also helps us fight depression, all of which positively impact the quality of our lives. Train yourself with red light therapy from the three dimensions of body, mind, and spirit to achieve good health, energy, and vitality.
