Photobiomodulation (PBM) refers to the use of red or near-infrared light to stimulate, heal, regenerate, and protect injured, degenerated, or dying tissue. The brain is susceptible to a variety of different conditions, which can be divided into three major categories: traumatic events (stroke, traumatic brain injury, and global ischemia), degenerative diseases (dementia, Alzheimer’s disease, and Parkinson’s disease), and psychiatric disorders (depression, anxiety, and post-traumatic stress disorder). There is evidence that all of these seemingly unrelated conditions can be beneficially affected by shining light into the head. PBM can even be used to enhance cognition in healthy individuals. In this application of transcranial PBM (tPBM), near-infrared (NIR) light is typically applied to the forehead because it has better penetration (no hair, longer wavelength).

Red/near-infrared light can stimulate complex IV (cytochrome c oxidase) of the mitochondrial respiratory chain and increase ATP (adenosine triphosphate) synthesis. Furthermore, absorption of light energy by ion channels leads to the release of Ca2+, activating transcription factors and gene expression. Infrared light can enhance neuronal metabolic capacity and stimulate anti-inflammatory, anti-apoptotic, and antioxidant responses, as well as neurogenesis and synaptogenesis.

Recommended for High Frequency Use of Diseases

Major disease categories	Specific Disease	Recommended Frequency
1.Cerebrovascular diseases	Cerebral arteriosclerosis, cerebral ischemia	50 Hz
	Cerebral thrombosis, cerebral infarction	50 Hz
	Lacunar cerebral infarction	50 Hz
2.Neurodegenerative diseases	Cerebral atrophy,Alzheimer’s disease (AD)	40-50 Hz
	Parkinson’s disease	30-50 Hz
3.Brain injury and recovery period	Postoperative recovery period after brain trauma	30 Hz
	Cerebral intoxication recovery period	30-50 Hz
4.Psychiatric disorders	Depression	50 Hz
	Mental disorders	30-50 Hz
5.Somatic and functional symptom-related diseases	Neural headaches	20-40 Hz
	Brain fatigue,Memory loss	30 Hertz

These diseases are often accompanied by abnormal brain hemodynamics, disordered neuronal activity rhythms, or poor metabolic function. High-frequency (30 Hz and above) 810nm photobiomodulation is more suitable for matching the neural electrical activity characteristics and energy requirements of these pathological conditions. By enhancing the penetration depth and intensity of light energy, it can effectively improve cerebral blood supply, promote neuronal metabolism, and regulate abnormal neural rhythms, thereby alleviating ischemic symptoms, delaying neurodegeneration, accelerating brain damage repair, and improving mood and physical function. At the same time, high-frequency modulation can more accurately activate the functional networks of relevant brain areas, improving intervention efficiency.

Recommended for Low Frequency Use of Diseases

Major disease categories	Specific diseases	Recommended frequency
1.Neurodevelopmental and Childhood Disorders	Children with Autism	10-30 Hz
	Children with Cerebral Palsy	5-15 Hz
2.Psychiatric Disorders	Neurasthenia	5-20 Hz
	Schizophrenia	5-20 Hz
3.Sleep and Somatic Symptom Disorders	Insomnia	5-15 Hz
	Hypertension	5-15 Hz

These diseases are often associated with immature neurodevelopment, imbalanced neural excitability, or autonomic nervous system disorders. Low-frequency modulation is more suited to the sensitive state and rhythmic characteristics of their nervous systems: for children with autism and cerebral palsy, gentle stimulation can regulate abnormal neural connections in the brain, improving social interaction, language skills, and motor coordination. For neurasthenia and schizophrenia, it can soothe overactive neural discharges, relieve anxiety and tension, and stabilize emotions and thinking. For insomnia and hypertension, it can regulate autonomic nervous rhythms, inhibit excessive brain excitation to improve sleep quality, and assist in balancing sympathetic nervous system activity and helping stabilize blood pressure. Overall, by adapting to low-frequency gentle photobiomodulation, targeted improvements in neurodevelopment, mental state, and physical function are achieved, overstimulation of sensitive nervous systems is reduced, and the safety and adaptability of modulation are improved.

Irradiation with 810nm light can modulate calcium ion concentrations and related signaling pathways within vascular smooth muscle cells, restoring normal contraction and relaxation of smooth muscle cells. In cases of cerebral vascular damage or chronic ischemia, photobiomodulation can also stimulate the expression and secretion of related growth factors, such as vascular endothelial growth factor (VEGF). These growth factors promote endothelial cell proliferation, migration, and differentiation, inducing new angiogenesis and establishing new collateral circulation. This plays a crucial role in improving blood supply to ischemic areas of the brain, as well as in vascular repair and neurological recovery after cerebral infarction.

The emitted near-infrared light can penetrate the scalp and skull, and be absorbed by the cytochrome c oxidase in the mitochondria of nerve cells, thereby enhancing mitochondrial respiration, promoting ATP production, and supplying energy to nerve cells. At the same time, it regulates neurotransmitter levels, promotes the synthesis and release of serotonin and dopamine, and maintains the balance of excitation and inhibition in the brain. It can also activate anti-apoptotic pathways such as PI3K/Akt to inhibit apoptosis of nerve cells. It stimulates nerve and glial cells to secrete nerve growth factor, which helps the growth of nerve cell axons and dendrites and the reconstruction of synaptic connections. It also inhibits the excessive activation of microglia, reduces the release of inflammatory factors, and alleviates neuroinflammation. From the dimensions of energy supply, transmitter regulation, anti-apoptosis, repair promotion, and anti-inflammatory, it protects the health of nerve cells and promotes the recovery of damaged nerve function.

Red and near-infrared light photons penetrate the skull and enter brain cells, stimulating their mitochondria to produce more ATP, thereby promoting neuronal metabolism. Activating cytochrome C oxidase on the mitochondrial membrane accelerates cellular energy production, increases blood flow, and stimulates the secretion of various neuroprotective proteins and growth factors.

There is no need for invasive procedures such as surgery or injections. The near-infrared light emitted by the helmet penetrates the scalp and skull and directly acts on the brain tissue, reducing the risks of infection and bleeding. It is relatively safe and suitable for all types of people, especially those who are concerned about invasive treatments.

As people age, their brain function gradually deteriorates, leading to memory loss, difficulty concentrating, slow thinking, and even the risk of mild cognitive impairment or dementia (such as Alzheimer’s disease). This helmet can help delay cognitive decline and maintain memory and thinking skills by improving brain metabolism and promoting neuroplasticity.

Such as Parkinson’s disease and Huntington’s disease, often experience neuronal damage and decreased motor and cognitive function during their illness. The helmet’s neuroprotective and repair mechanisms (such as promoting mitochondrial function and inhibiting inflammation) can help improve the state of neurons and alleviate cognitive symptoms (such as distractibility and decreased executive function).

After a stroke (cerebral infarction, cerebral hemorrhage) or brain trauma, the brain may suffer from ischemia and hypoxia, leading to damage to nerve cells and symptoms such as memory impairment, difficulty concentrating, and illogical thinking. Helmets can help restore damaged nerve function and accelerate cognitive recovery by promoting neural repair and improving cerebral blood flow and metabolism.

Such as depression and anxiety, often experience cognitive symptoms like inattention, slow thinking, and memory loss. The helmet can regulate neurotransmitters (such as serotonin and dopamine), improve the brain’s microenvironment, help alleviate negative emotions, and enhance cognitive function. Furthermore, patients with chronic fatigue syndrome caused by long-term stress can benefit from it by improving brain energy supply and alleviating problems like inattention and inefficient thinking.

Such as students facing high-intensity learning pressure and professionals who engage in long-term mental work may experience temporary memory loss, difficulty concentrating, and reduced thinking activity due to brain fatigue. The helmet can help improve brain state and enhance short-term cognitive performance by optimizing cerebral blood flow and enhancing nerve cell metabolism.

People with chronic insomnia or poor sleep quality are prone to memory loss and difficulty concentrating due to insufficient brain rest. The helmet can help improve sleep-related cognitive problems by regulating nerve function and improving blood circulation in the brain, indirectly enhancing the brain’s focus and information processing abilities.
