The story of weighted blankets and deep pressure stimulation, the inspiration behind Nerax.

Having a moderate amount of weight on your eyes while you sleep may improve the quality of your sleep.

This effect is also suggested by research into the use of weighted blankets, which are blankets with a moderate weight that are primarily used to reduce anxiety and insomnia.

One of the reasons for this effect is deep pressure stimulation.

Deep pressure stimulation is a method of relaxation that applies moderate pressure to the body. This pressure activates the parasympathetic nervous system, lowering heart rate and blood pressure and reducing the stress hormone cortisol. This is thought to promote relaxation and make it easier to fall asleep.

Holding weight over the eyes may provide deep pressure stimulation to specific areas of the face, which may have a similar relaxing effect. In particular, there are many nerves around the eyes, and it is thought that moderate pressure may stimulate these nerves and promote relaxation.

However, there is limited concrete clinical data regarding the use of weight on the eyes. Therefore, care must be taken to consider individual differences and usage methods. Care must be taken to select the appropriate weight and material, and to avoid prolonged use.

The following literature is a study on the effectiveness of weighted blankets:

Chen, H.-Y., Yang, H., Chi, H.-J., & Chen, H.-M. (2013). Physiological effects of deep touch pressure on anxiety alleviation: The weighted blanket approach. Journal of Medical and Biological Engineering, 33(5), 463–470.

This study suggests that using a weighted blanket may help reduce anxiety. Placing weights over the eyes may also improve sleep quality through a similar mechanism, but more research is needed.

Deep Pressure Stimulation (DPS) is a technique that applies uniform pressure over a wide area of the body to induce relaxation and a sense of security. This technique is used as part of sensory integration therapy and relaxation techniques, and is said to be effective in reducing anxiety and regulating the autonomic nervous system.

How deep pressure stimulation works

Deep pressure stimulation works through the following physiological mechanisms:

Activation of the parasympathetic nervous system : Deep pressure stimulation activates the parasympathetic nervous system, slowing your heart rate, stabilizing your breathing, and lowering your blood pressure. This puts your body into "rest mode" and promotes a state of relaxation.
Promotes the release of serotonin and oxytocin : Even pressure sends a relaxation signal to the brain, increasing the secretion of neurotransmitters called serotonin and oxytocin (happiness hormones). This gives you a sense of security and happiness, and reduces anxiety and stress.
Reduction of cortisol (stress hormone) Deep pressure stimulation is said to suppress the secretion of the stress hormone cortisol, making it effective for stress management.
Stabilizing sensory processing : By allowing the nervous system to receive pressure stimuli, it is believed to have the effect of reducing sensory hypersensitivity and hyposensitivity, which is particularly beneficial for people with developmental disorders and sensory integration disorders.

How to practice deep pressure stimulation

Deep pressure stimulation is achieved in the following ways:

Weighted Blanket <br>Use a blanket that is evenly weighted. Weighted blankets provide deep pressure by enveloping the entire body. A weight of 10-15% of your body weight is generally considered appropriate.
Hugs and pressure devices Hugs and specialized pressure delivery devices (such as chairs or vests) can also be used to provide deep pressure stimulation.
Manual therapy (massage)
Deep pressure stimulation can also be achieved by applying pressure directly to the body with your hands, as in massage or acupressure.

Situations in which deep pressure stimulation is effective

Deep pressure stimulation is effective for the following problems and conditions:

Anxiety and stress : Deep pressure stimulation activates the parasympathetic nervous system and brings about a relaxed state, helping to reduce anxiety and stress.
Insomnia : Deep pressure stimulation before bed helps relieve tension in the mind and body and induces deeper sleep.
Developmental disorders (ASD, etc.)
Many people with autism spectrum disorder (ASD) suffer from sensory sensitivities and anxiety, and deep pressure stimulation can help provide calming relief.
Panic disorder and PTSD
It may also be effective in reducing panic attacks and overreactions from past trauma.
Improved concentration : It has been reported that the relaxation effect reduces excessive sensory stimulation and improves concentration.

About the burden

Deep pressure stimulation does not put strain on the body, but care must be taken with how and for how long pressure is applied.

Appropriate weight <br>Excessive weight can put strain on the body and cause blood flow problems, so it is necessary to adjust the weight to suit each individual's weight and build.
Duration of Use : If strong pressure is applied for a long period of time, you may feel a sense of pressure or discomfort. It is recommended to start with a short period of time and adjust accordingly.
Consideration of physical condition <br>People with respiratory or circulatory diseases should be careful when using deep pressure stimulation. It is recommended to seek medical advice.
