Can an Android phone affect your sleep?
Blue Light interrupts our Circadian Rhythm, which is the sleep-wake cycle.
Your circadian rhythm is the sleep-wake cycle that’s regulated by light. If you’ve ever heard someone mention the phrase “circadian rhythm,” they were referring to this. Melatonin is the hormone that regulates your circadian rhythm, and it’s triggered in part by darkness. Blue light is a specific wavelength of light and it can be particularly disruptive to our sleep cycles especially at night because it suppresses melatonin production.
So what does blue light have to do with your phone? Well, LED screens emit blue light and if you’re scrolling through Facebook before bedtime, you might just be messing up your Circadian Rhythm.
This light is also released by electronic devices such as cell phones.
While the science behind blue light’s effect on sleep is not definitive, it may be beneficial to reduce exposure to blue light in the evening and before sleeping. This light can affect our circadian rhythm—our bodies’ natural wake-sleep cycle that is regulated by how much exposure we get to sunlight throughout the day.
Because blue light can pass through the retinas and get into the brain, it’s possible that it may cause cognitive fatigue and become a source of insomnia. While more research needs to be done in this area, we do know that overexposure to blue light can decrease melatonin production; melatonin is a hormone that helps us fall asleep.
This light can actually enter the brain by passing through your retinas.
As you may have experienced, the blue light can affect your sleep by disrupting your natural circadian rhythm as well as increasing alertness. Blue light can also be called high energy visible (HEV) light. HEV light is produced naturally by the sun and has a shorter wavelength than other colors of light. While there is nothing inherently wrong with blue light, it does have these two negative effects on our bodies that are important to note and understand why we should avoid exposure at night-time.
The first effect occurs because blue light can actually enter the brain by passing through your retinas, which triggers the neuroendocrine system to release hormones like cortisol and adrenaline that keep you awake. The second effect happens when these same hormones suppress melatonin production. Melatonin is a hormone in our body that helps regulate sleep patterns and your body’s overall circadian rhythm or internal clock.
This can cause cognitive fatigue as well as a decrease in melatonin production.
The light from your smartphone, tablet, or laptop can affect the production of a sleep hormone called melatonin. This can cause cognitive fatigue as well as a decrease in melatonin production.
Melatonin is a hormone that regulates circadian rhythm and helps you sleep. It’s produced in the pineal gland, located in the brain. The pineal gland produces high levels of melatonin at night when it’s dark — helping to induce sleep. In the morning, when it’s light out, production declines and you wake up.
Low melatonin levels can cause poor sleep and insomnia. Poor or insufficient sleep can lead to several physical and mental health conditions like:
- heart disease
- impaired immune function
Melatonin is a hormone that helps to regulate sleep.
The production of melatonin is triggered by darkness, and suppressed by light; this is called a circadian rhythm (from Latin words that mean “about a day”). Your brain naturally releases more melatonin as the day goes on and you get closer to bedtime. Melatonin levels will stay high for the majority of the night, then drop in the early morning as light increases.
It’s easy to see why blue light can mess with your sleep schedule when you look at its impact on melatonin. The blue wavelengths emitted by smartphones, tablets, and computer screens are short, meaning they carry more energy than longer wavelengths — like red or orange ones. These short wavelengths also happen to affect our bodies similarly to sunlight; thus, we find ourselves alert and awake during daylight hours when we should be going about our days.
In addition to affecting your natural sleep-wake cycle, exposure to blue light at night may increase your risk for certain cancers, diabetes, heart disease, and obesity. It may also accelerate skin aging.
Long story short, your android phone (or other smart phone) can affect your sleep
The world has never been crazier, and we’re only getting started. Some health experts are worried that the constant barrage of bright light emitted by our smartphones may actually be affecting our sleep.
The fact of the matter is, there’s no way to know if your phone is affecting your sleep without talking to a professional, but scientists are sure that it can.
Research points to various negative effects of smartphone use on sleep patterns.
Studies show that keeping phones close at night disturbs melatonin production in humans; a hormone that helps regulate the body’s internal clock, which helps us get more restful sleep at night. Melatonin can also reduce eye pressure, which would likely leave you feeling tired and sick. All of this lowers cognitive performance and cognitive fatigue during waking hours, which may have an effect on your ability to concentrate properly throughout the day and make difficult decisions later in life (like quitting smoking or developing alcohol dependency).
