Could red light therapy be used to help us sleep and help us relax more? In this second installment of our series exploring the technology behind the handheld red light device we discuss the significance of the circadian rhythm and our ability to release the hormone melatonin.  We also explore the longer-term implications for our energy levels during the day and healthspan. Dr. Zulia Frost is a medical doctor and clinical director at Recharge Health, creators of a targeted red-light device, known as FlexBeam. In this conversation we cover:Dr. Frost explains that the technology has many applications, including the treatment of sports injuries, therapy for age-related aches and pains and as way to help improve sleep.Sleep disorders can be caused by an imbalance in the autonomic nervous system, which controls our sleep-wake cycle.Lack of sleep can lead to physical and mental fatigue, decreased cognitive function, and increased risk of accidents and mistakes.Technology and exposure to artificial light, especially blue light from screens, can disrupt our natural sleep patterns.Red light therapy, such as the FlexBeam device, can help improve sleep by stimulating the release of melatonin, a hormone that regulates sleep-wake cycles.Melatonin is released by the pineal gland, as well as various cells throughout the body, in response to red light.Red light therapy can also improve mitochondrial function and reduce oxidative stress, which can contribute to sleep disturbances.The optimal time and duration of red light therapy for sleep improvement may vary depending on individual needs and responses.Using red light therapy on specific areas of the body, such as the stomach, thymus, back of the neck, and sacrum, can target the release of melatonin and promote relaxation.Red light therapy should be used consistently, but not excessively, to allow the body to adapt and self-regulate melatonin production.Affiliation disclosure: This podcast receives a small commissionFlexBeam red light therapyRecharge Health is offering a discount on the purchase of FlexBeam, the wearable red light therapy device which targets key parts of the body to improve sleep/treat injuries/sooth aches/pains.  Sale price US$369 (down from $449) + an extra $10 off use code equinox  Sale ends Sept 21: 0259 PST DoNotAgeDoNotAge.org is offering listeners to LLAMA a 10% discount on its range of products – NAD boosters, Sirtuin activators, senolytics and more.  Any health queries can be answered by emailing the team at hello@donotage.orgUse the code LLAMA at checkout. - Time-line Mitopure (a highly pure form of Urolithin A) boosts the health of our mitochondria – the battery packs of our cells – and improves muscle strength.
