NASA: Using Light Therapy to Increase Astronauts’ Sleep Quality

Timed light exposure treatment is recommended by the American Academy of Sleep Medicine (AASM) as a drug-free method to control and improve sleep quality. In 2012, NASA used timed light exposure treatment to improve astronauts’ sleep quality and proved that this method was effective.

Pegasi Smart Sleep Glasses 

Give You a Better Sleep in Blink 

PEGASI, a smart medical certified sleep glasses, brings this innovative technology to the public, giving people a brand-new experience of controlling the sleep quality in hand. The light therapy can help your body to manage the biological clock and regulate the circadian rhythm to improve sleep quality.

PEGASI glasses generate a specific wavelength green light and transmit it into our inner retina. Suprachiasmatic nucleus, the core controller of our body’s internal secretion on hypothalamus, adjusts the secretion levels of melatonin under different situations.

Melatonin: A Main Hormone Regulates Your Sleep Cycle

A hormone created by the pineal gland which helps your body to know when it’s the time to sleep and wake up. Normally, your body secretes a high level of melatonin at night to help you fall asleep. And the secretion level goes down at sunrise. The amount of the light your body received determines how your body adjusts your mood and energy.

Once Suprachiasmatic nucleus receives the light signal from PEGASI, an order will be sent to the brain to inhibit the secretion of melatonin. This inhibition can last a few hours to help you stay away from sleepiness. Based on the ideal biological clock for most people, the best using time is 7 am – 9 am. After daytime, melatonin will be released drastically to help you fall asleep smoothly in the night.

Why Pegasi Sleep Glasses

1. Say goodbye to pills 

PEGASI specific wavelength light helps to restrain melatonin secretion in the daytime and stimulate melatonin releasing at night. It works like a natural light, keeping your body work regularly. Forget about sleeping pills. You never need them anymore!

2. PEGASI Does Work

Clinical Proof

PEGASI conducted a clinical trial at the First Hospital of Hebei Medical University. The results showed that compared with the control group’s time of falling asleep, the average time of falling asleep of the treatment group who used PEGASI smart sleep glasses was reduced by up to 37%.
