Bright Light At Night Throws Off Sleep Wake Cycle

As strange as it may sound, bright light at night throws off your body clock. Your body clock is a synchronizer-a device that helps you keep time-and when it starts to run out, it can throw your sleeping pattern out of whack.

  • The problem with your body clock is that it doesn’t know when to slow down or stop.
  • Some people are naturally more resistant to change than others are and their bodies may not always respond to artificial means.
  • However, there are ways to make the body clock adjust to your lifestyle and give you and your family better sleep at night.
  • Bright light at night can really throw your bodywork out of whack if you’re accustomed to staying up late for work or playing games.
  • If you have trouble sleeping because you need to stay awake for the family or yourself, try going without any artificial light at night.

Avoid as much light as possible in the area where you live or where you work to make sure that light at night doesn’t affect your sleep.

For those who live in a city or town where streetlights are common, the lighting outside your window may also be too bright.

Try to use ceiling fixtures instead of exterior lights if you can.

Make sure to shut off any light fixtures when you leave the house, even if you don’t need them at that moment.

Going to bed with a bright light at night is very difficult for most people, but if you’re able to adjust your light fixtures and shut off unnecessary lights, you’ll sleep better and wake up much easier each day.

Best to Sleep Without Light

If you suffer from insomnia, the best way to sleep is to go to sleep with the lights off.

This is especially true if your bedroom is quite dark because it will be difficult to sleep when bright lights are shining in your eyes or your head is being throbbed with light.

This is why it is said that the best time to sleep is actually in the darkness because even a small amount of sleep can help.

  • The problem is many people don’t really know how to go about avoiding this and as a result end up tossing and turning at night.
  • You might want to start by looking around your bedroom. The best way to sleep without a light is to simply avoid the things that shine especially in the light that shines in your eyes.
  • This means removing any decorations that have lights on them such as on picture frames or mirrors and also getting rid of any TV sets that have televisions built into them.
  • There is no need for these things to shine because they will keep you from getting to sleep.
  • As a result you will only be absorbing more light, which will mean a lower chance of being sleepless.
  • In addition to this there are also things you can do to avoid being awake while sleeping by using motion detectors.

Motion detectors can make it much easier for you to fall asleep because they will automatically turn on the lights at the appropriate time so you won’t have to worry about them shining into your eyes.

As a result, your chances of falling asleep will be greatly increased and you can enjoy a peaceful night’s sleep.

Why Do Our Eyes Are More Sensitive to Green and Yellow Lights at Night?

ColorWavelength ( nm )
Violet390 to 455
Blue455 to 492
Green492 to 577
Yellow577 to 597
Orange597 to 622
Red622 to 780

The table above shows you that eyes will be more sensitive to shorter wavelengths. Eyes will be very sensitive to violet, blue, green and yellow.

The red has the longest wavelength and eyes will be comfortable with it.

In our research, we have found out that the eyes of human beings are more sensitive to green and yellow lights at night.

The eyes are capable of blocking these harmful light rays because it has a coating in their lens to reflect them.

However, there are certain environmental factors that can reduce the effect of this protective coating and make our eyes prone to be affected by harmful light at night.

Pollution, outdoor lighting and glare from nearby buildings are some of these environmental factors that reduce the effect of the protective lens coating. Thus, having the right protective eyeglass like sunglasses can protect your eyes against the harmful effect of these environmental factors at night.

human eyes are more sensitive to green and yellow lights at night

Aside from the protective coating in the human eyes, the pupils of our eyes also play an important role in regulating the amount of light that goes into our eyes.

The larger the pupil in our eyes means that more light will enter our eyes to form an image. However, the smaller the pupils are, the lesser amount of light will enter our eyes to form an image. Thus, having larger pupil in our eyes can help us reduce the amount of light that goes into our eyes during nighttime.

Now, if you really want to take care of your eyes at night and not get dazzled by the yellow and green light during the day then the best solution that you should do is to use LED sunglasses. These LED sunglasses are equipped with the technology that helps reduce the exposure level of the light that goes into our eyes during nighttime. Usually, these kinds of sunglasses are also available in dark colors so that people will not be able to see the green and yellow lights at night. These sunglasses also help to block out the red, blue and ultraviolet light that can harm our eyes in the night. With these sunglasses, you will be able to enjoy outdoor light during nighttime without having to worry about the possible damage that these light rays can do to your eyes. Try using this amazing pair of LED sunglasses today for great results.

How Do The Waves Of Light Affect Your Sleep Channels?

Did you know that different wavelengths of light have different effects on the ability to sleep?

Well, it is true. Certain wavelengths of light have the ability to wake us up from a deep sleep and stimulate the brain and central nervous system.

Conversely, other wavelengths of light may actually suppress this natural ability to sleep.

different wavelengths of light have different effects on ability to sleep

Research has shown that certain wavelengths of light have the ability to induce different kinds of dreams or states of being in dreamlike states.

Different wavelengths of light stimulate different brainwave activities and even can alter the speed of your metabolism. So, depending upon which wavelength of light you are exposed to while you are asleep, depending upon whether or not you will be able to sleep soundly at night, the level of stimulation you receive may be different.

For instance, blue light has the ability to stimulate melatonin, which is a hormone secreted by the pineal gland.

Melatonin is a hormone that helps people sleep. It helps them get in and out of REM sleep and also helps them to wake up during the day without a problem.

However, too much blue light can also inhibit melatonin production.

This means that if you are going to use this wavelength of light for treating insomnia, you may want to use a natural sleep aid instead of a prescription drug that may have harmful side effects.

The other wavelength that has different effects on the ability to sleep is red light. Red light stimulates the production of adrenaline. This hormone is produced because it is excited by heat, which then causes the body to increase heart rate. It can also increase blood pressure and can cause the body to sweat. Although, again, too much red light can stimulate hypertension and cause problems with the immune system.

  • The last different wavelength to consider is red light.
  • This is the most powerful of the different wavelengths that can be used for treating insomnia.
  • It is a good bet that your grandmother slept with a red lamp beside her bed.
  • The wavelength works especially well at night because our eyes are less sensitive to light at night.
  • However, when using this light source for treating insomnia, it is important to remember that people who are highly sensitive to light are not good candidates.
  • As you can see, understanding how different wavelengths of light affect our sleep cycles is key to developing a healthy lifestyle that includes an effective sleep routine.

If you need to treat insomnia, make sure that you understand how different wavelengths can affect your body so that you can choose the best treatment for your personal situation.

It is also important to understand that there are different levels of light sensitivity so be sure to talk with your doctor about whether or not light therapy is right for you.

Once you are able to understand how the different wavelengths of light effect your sleep cycles, you will be able to make educated decisions about which treatments are best for your needs.

Why Do Human Eyes Not Settle Over And Make Contact With Light?

human eyes are not sensitive to blue and red lights at night

The answer is that it depends.

In a laboratory setting, where there are no other light and no other matter to experiment with, the human eye is probably most sensitive to yellowish-green color.

In daylight, the eye will more than likely be sensitive to green and yellow lights.

The least sensitive for the eyes is red light.

There are a lot of things that can cause this sensitivity to light at night.

Some of these things are quite technical, but for the sake of simplicity just think about things like flashlights.

Flashlights have extremely bright lights, and they can produce a lot of ultraviolet light. Normal human eyes can only take so much of this light, so if you put a flashlight next to your eye, and shine it on to your pupil, the light that reflects off of the back of your iris is filtered through the human cornea and is sent to the back of the eye, where it is reflected on the retina, causing your eye to darken.

In this way, the human eye cannot fully absorb the red and blue light that is reflected off of the flashlight.

So the next time you try to use a flashlight during the night, just try to use an old photo camera instead.

Another thing that can cause the eyes to be sensitive to light at night is very loud noises. This is especially true if the sound is not near your ear, or if it is very far away. Many people experience this because of a train coming near their home or the sound of an explosion. If you are near these sounds at night, your cornea will become inflamed because of the amount of light that is being reflected onto the back of the eye.

Why Do Red Light Lenses Give Me Less Sensitivity?

So, why do red light lenses give drivers a warning when the red light is turned on?

That’s because they have longer wavelengths, which make them less sensitive to shorter wavelengths, which normally cause flicker during the operation.

This means that if you are traveling at 45 degrees with a traffic light, your red light will turn on sooner than if you were driving at say, a state highway. Why would this be important? Well, imagine this scenario:

red light have longer wavelengths and eyes are less sensitive

You are on a red light cycle, and you are stopped at a stop light.

The cop is coming up from behind you, and his eyes are very close to your vehicle.

As he starts the scan, he accidentally hits your red light, and you are now in violation of the red light law.

In addition, if he had started the scanning process from your red light position, he would have hit your stop light, and you could have been ticketed.

In this case, your longer red light wavelength allows you more time to react, resulting in a reduced chance of being ticketed.

With regards to the specific red light bulb used by your red light system, it will have a slightly different detector than a blue one, resulting in less sensitivity to shorter wavelengths.

How is this relevant? Well, imagine driving on a freeway, where drivers have to drive onto one side of the freeway to enter, while the other drivers can move freely between directions.

Now, imagine if we place the red light at the center of these two freeway systems.

If the red light detector had a detector that was sensitive to shorter wavelengths, it would only detect vehicles on the left side of the freeway, which means it would not detect a car on the right.

Why Does Red Light Make You Lazy and Lower Depression?

red light makes you sleepy and lowers depression

Have you ever wondered why do the red light makes you sleepy and lowers depression in your brain?

If so then you have to know about the science behind it.

According to various researches and studies conducted on this subject, the red light creates an excited state in our brain that makes us fall asleep instantly.

Some people are not able to sleep because of this reason.

This is also known as the sleep cycle disorder or the light/vision disorder.

The red light makes you sleepy and lowers depression in your brain is due to the long wavelength light which passes through our eyes and our retina and enter our brain that makes us fall asleep immediately.

When we go to sleep all the muscles in our body will relax and our internal organs slow down their functions.

Our brain works at a slower pace and this is the reason why we feel drowsy.

This is also known as the pineal gland which is located in our brain and its job is to produce melatonin, which is responsible for the mood and the sleeping cycles in our body.

When our pineal gland produces less amount of melatonin then the person becomes less creative and attentive.

When there is lack of creativity, one gets depressed and loses his passion and interest in life.

Our pineal gland controls and regulates the production and level of melatonin in our body, if there is a high level of melatonin then we feel well and comfortable.

However when there is low level of melatonin then we feel sleepy and sad which is a very bad feeling.

How Do Red Light Applied To The Brain Increase Cerebral Blood Flow And Create Healing?

red light applied to brain increase cerebral blood at night

Studies have revealed that when the red light is turned on, oxygen is reduced in the brain and this can lead to problems in the short term. The results of decreased oxygen in the brain are shown by decreased blood flow and this is what will cause the symptoms of memory loss, drowsiness, fatigue and poor concentration.

Red light therapy was originally developed as a treatment for patients who suffered with head injuries and this has been widely used to reduce or eliminate the symptoms of post traumatic stress disorder and degenerative brain diseases like Alzheimer’s.

However, it has also been used to treat other problems like sleep apnea, depression, epilepsy and excessive daytime sleepiness.

One of the biggest advantages of using the red light therapy is that it provides very quick results.

Patients who have undergone this type of treatment have shown improvements in their brain function after just one session and there have even been instances where patients have seen results after the second session.

This means that a person does not have to undergo the whole treatment course over the course of months.

There is also no need for a follow up session that would involve the administration of medicines or any other invasive methods that may need to be done regularly.

It is simply a matter of applying the red lighted lights and going to bed for the night.

However, the red light is not suitable for all patients. The brain reacts differently to the light and if you are looking for a treatment that will give you good long term effects, then the red light is not the way to go.

  • If you suffer from high blood pressure or a heart condition, then this treatment is not for you as it will have negative implications on your health.
  • In addition, women who are pregnant or nursing and are expecting, do not use the red lighted lights because it will create havoc with the development of their fetus.

ATP Energy Production

red light therapy increase ATP energy production

Red light therapy has recently been found to be very effective in increasing ATP (adenosine triphosphate) energy production and the regeneration of muscle. ATP energy production is a constant process in all aerobic exercises such as sprinting, cycling, swimming, etc. The maximum amount of ATP energy is generated when the respiratory muscles are at their most efficient for this type of exercise. In the case of bodybuilding, when the athlete trains hard, the ATP energy production is naturally lowered because of the lower efficiency of the anaerobic system for this purpose.

Red light therapy, by increasing the efficiency of the anaerobic system for this purpose, allows the athlete to train harder, longer and more efficiently. The red light therapy supplement was developed by combining the use of a very powerful and effective red light photochemical, known as ATP Choline, with a step that allows the supplement to enter the muscles and be absorbed and used. This combination allows for the red light therapy to not only increase the energy and stamina of the body during exercise, but also allows the red light therapy to work even better when taken minutes before the workout and then again minutes after the workout. The increase in ATP energy is then used immediately.

For bodybuilders, this means two things. First, it allows them to recover more easily from intense training sessions and build more muscle while they are recovering. Second, the red light therapy supplement helps to burn up any excess fat or carbohydrates that might be trying to take up space in the body, since it is all about getting the nutrients where they are needed, and quickly. The red light therapy supplement has been proven to work in many different circles and is gaining popularity and effectiveness all over the world. So, if you’re looking to increase your training intensity, improve recovery and speed muscle growth, then this supplement could be the answer for you.

Does Red Light Therapy Increase Neuroprotection?

red light applied to brain increase neuroprotection

Neurons in the human brain are protected by the specialized blood vessels called the corpus cavernosa and by the diencephalon that lines the cavity. When the brain is exposed to light, the corpus cavernosa dilates and the light acts as a selective filter. As a result, brief flickers of light can bypass the photoreceptor layer and reach the inner layers of the cortex where the brain’s nerve cells and synapses are located. In neurons, light can trigger or inhibit synaptic activity, which has implications for learning and memory in addition to evading the damaging effects of red light. The results of red light exposure on learning and memory can be of particular interest because they reveal both the strengths and weaknesses of such an approach.

For instance, when red light is applied to the human brain, it appears to activate both types of diencephalic neurons (memory and information processing neurons) but only those that are actively receiving light.

Over time, this process appears to deplete these neurons, impairing performance on cognitive tasks and increasing both the likelihood of experiencing a traumatic event and the severity of that event.

As it becomes clear that the red light is a powerful agent for cognitive neuroprotection, more hospitals, nursing homes and other healthcare centers are adding red lighted rooms to their patient care.

The apparent benefits of this procedure are not based on knowledge of how it works or on the effects of long-term exposure, but on knowledge of the underlying mechanism.

In essence, red light applied to the brain through surgery reduces both the likelihood of a traumatic event and the intensity of that event.

Neuroprotective mechanisms such as those found in the eye and nose begin operating immediately to protect the brain from light.

When the organism is exposed to light for prolonged periods, the light-sensitive pathways in the brain begin to die.

The reduction in cellular communication and eventually the death of specific cells is what constitutes the neuroprotection provided by red light therapy.

This study offers an exciting insight into the role of red light in the human body and provides new insight into the care and possible curative mechanisms of this light therapy in the treatment of patients with brain injury.

A Hard-To-Shake Lazy Feeling When Waking Up in the Morning

Although I never had the problem of sleep deprivation during my young days, I’m yet to experience the Insomnia experienced by many Insomniacs.

This is primarily because, although the Insomniac’s condition of mind is conducive to such a state, it is not easy to stay asleep after sleeping for long hours due to the presence of certain triggers and disturbing conditions in the environment.

The presence of sleep ions and melatonin, the former anatomic derivative, acts as a natural lullaby to the patient, inducing deep sleep without inducing the feeling of fatigue or leaving you groggy and sluggish.

Sleep inertiathat hardtoshake groggy feeling upon waking up

Melatonin is actually produced by the pineal gland and accounts for the melodic tune of melosomes, or dream signs.

Insomnia sufferers have reported falling asleep to music, watching television or even reading a book prior to going to bed.

These activities are proven to be very effective in inducing sleep but unfortunately, they also block the production of melatonin leading to a hard-to-shake lazy feeling upon waking up in the morning.

Melatonin is a natural sleep chemical that is produced by the pineal gland. It is produced naturally in the absence of light or dark.

Sleep Insomnia treatment options can either come in the form of synthetic drugs like Zolpidem, Ambien CR, Lunesta, and so forth. Unfortunately, synthetic drugs are known to induce side effects that are somehow unrelated to sleep.

Natural herbal supplements are better alternatives as they contain ingredients that are completely safe, have no adverse effects and also promote proper sleep hygiene.

Natural sleep ion generators are available in the form of ear plugs, wearable body heaters and other portable devices that generate a natural and relaxing flow of sleep ions in the body.

Sleep Insomnia treatment options which use melatonin are safe and effective as they act on the brain and pineal gland directly thereby boosting and enhancing normal melatonin levels.

Sleep Insomnia treatment options which use sleep ion generators are effective and inexpensive.
