travel with a red light device in the suitcase

As the winter holiday approaches, many people want to take advantage of the vacation to visit distant places. Maintaining optimal mental and physical health during traveling is important to stay productive and fully enjoy new experiences. Preventing sickness from exposure to germs in transportation is always a concern, especially for people constantly traveling. Long-distance and frequent trips also increase the risk of sleep disorders and low immunity.

Would it be possible to easily prevent travel-related health issues if you have a red light therapy device that can be carried with you? Today, let's explore the popular Red light therapy device to see if it meets expectations!

Red light therapy – Traveler's Health Aid

Red light therapy devices consist of visible spectrum light (red + near-infrared) LEDs with a 660–850 nm wavelength. Red light is known to exert a beneficial photobiomodulation effect on the human body, similar to natural sunlight. One of the core advantages of red light therapy is that it increases cellular energy by stimulating the production of adenosine triphosphate. ATP is the energy used by mitochondria to power cells, and an increase in cellular energy has many systemic health benefits.

The red light therapy device's slim size, lightweight, and long battery life make it suitable to use anywhere, including planes, trains, and hotels. Portable red light therapy is a unique option for travelers seeking an easy wellness solution.

Supports Restful Sleep

Sleep disorders are common among travelers, such as insomnia and restless legs syndrome. We should pay close attention to the dangers of sleep irregularities. Long-term insomnia may damage the nervous system and manifest as dizziness, headaches, fatigue, etc. The secretion of melatonin – a sleep hormone, is closely related to sunlight exposure. The pineal gland naturally secretes melatonin in the dark, and morning sunlight inhibits melatonin secretion.

If you are continuously in a bright light environment, such as traveling on a train at night, it can interfere with the secretion of melatonin, which in turn will cause a disturbance of sleep and body rhythm. When sleep duration is consistent with endogenous circadian rhythms, the best sleep quality can be achieved, and if this balance is disrupted, it can lead to insomnia or drowsiness.

Natural sunlight exposure during traveling may vary due to unpredictable factors such as sunny and rainy days. Due to the constant use of electronics on the journey, screens emit blue light, which inhibits melatonin. Conversely, red light therapy can help you calm and relax. There is evidence that red light therapy regulates melatonin levels and energy in the body to remove the adverse effects of sleep deprivation, such as drowsiness and difficulty concentrating. Red light phototherapy equipment can maintain the continuity and consistency of light. Based on this principle, using red light during travel or by nomad workers could improve sleep quality and reduce jet lag by regulating sleep-wake cycles. Current studies have shown that light therapy is more effective in the treatment of circadian rhythm disorders and sleep disorders.

Boost Immunity

Traveling makes the body more susceptible to infections due to disrupting dietary rules, climate change, and other reasons. Studies have shown that 40%–60% of travelers may experience gastrointestinal disturbances, so preparing for prevention before travel is extremely important.

For some infectious diseases, antibacterial or antiviral drugs do not treat the condition's cause and may prolong the duration of the illness. Adverse reactions to the body and environment can lead to loss of appetite, mental fatigue, and gastrointestinal problems. In short, it will affect the normal work arrangement.

Red light therapy has been shown to strengthen the functioning of the immune system. It can boost your body's energy and metabolism to keep you healthy. Red light therapy's positive effects on the immune system include the following:

  • The adenosine triphosphate (ATP) level increases enable cells to resist microbes.
  • Stimulates angiogenesis and improves blood flow throughout the body, providing nutrients to cells and removing waste products.
  • Increases the production of red blood cells and stem cells. Red blood cells can promote phagocytosis. Red light can penetrate deep into the organs and tissues of the human body. Various immune cells in the blood flowing through the body surface can receive red light and send immune cells to prevent and treat multiple infections.
  • Whether the infection is on the skin or deep within the body, red light therapy can help reduce inflammation. Inflammation interferes with the body's normal functioning and leads to many chronic diseases in travelers. Therefore, red light therapy can enhance immunity sterilization and reduce the likelihood of illness.

Tips for using Red Light Therapy

The duration of light should be short, generally 30~45 minutes per day. It is advised not to exceed the application of red light from the recommended dosage and duration. Red light therapy is currently recommended in combination with medications or other treatments for insomnia disorders. If you are suffering from insomnia, especially if you have jet-lag insomnia or difficulty in falling asleep, you can try light therapy.

To Wrap Up

Bestqool red light therapy is natural, simple, and low-cost, which does not result in any adverse effects. As red light becomes increasingly convenient to integrate into active lifestyles, its regular self-care use shows great promise for modern travelers.
