Research indicates that sleeping with red led lights is not bad at all. Indeed, using red led lights at night is good for helping people to sleep. The bright blue led lights used in laptops, PCs, smartphones or tablets should be avoided for at least an hour before you try to go asleep.
They are very bright compared to blackness in the middle of the night. I honestly recommend you to not leave led lights all nights but in gosund leds are compatible to work with alexa and Google assistant and voice command you easily on/off your led lights.
There are red lights on the market, and if you want to try them before all the research is in, “the best way would be to use a high-quality red LED light bulb in your room for 15 to 20 minutes consistently before going to bed daily,” says Dr. Posina.
But red light may have the opposite effect and aid in creating drowsiness. It might work in conjunction with melatonin, known as the “sleep hormone,” which helps regulate sleep and circadian rhythms.
Why do we see red lights at night?
Red light and night vision. The glare from bright white light at night can leave you squinting and straining to see clearly. Red light is non-glaring, so it can help you see better at night. That’s why you’ll find red lights in airplane cockpits and submarines, and why astronomers and stargazers like to carry red flashlights.
If you want to try red light for better sleep, choose products that emit red light wavelengths instead of bulbs that are simply tinted red. Also, try to expose yourself to sunshine and brighter lights in the daytime, dimmer lights in the evening, and darkness when it’s time to sleep.
What’s known about red light’s effects at night? The type of red light that affects your sleep is light that emits red light wavelengths — not simply light bulbs that are tinted red. While red-tinted light bulbs can be quite soothing and put you in a good mood, they don’t actually produce red light wavelengths.
The theory is that red light wavelengths stimulate the production of melatonin. Melatonin is a naturally occurring hormone that helps you sleep. Your brain releases more melatonin as darkness falls and tends to release less when you’re exposed to light.
It helps you feel sleepy at night when it’s dark and it also makes you feel alert during daylight hours. Light exposure provides your brain with information that guides your circadian rhythm. In a natural light pattern, your circadian rhythm follows sunrise and sunset.
In addition to lighting, you’ll want to take other sleep hygiene measures, like avoiding caffeine, alcohol, and vigorous exercise before bedtime.
That’s because blue light wavelengths can stop your brain from producing melatonin, the hormone that helps you feel sleepy. Blue light waves are emitted from the sun, as well as from:

Why do people use red lights at night?
The use of red led lights at night mean that people will find it easier to relax and then will go to sleep longer. The aim of using a red led light at night is to get to sleep sooner and to have a deeper and more relaxed sleep.
There is the potential for led lights to last for between 50,000 and 100,000 hours depending on their make, precise function and how long they are left on continuously. Although led lights can be more expensive when first brought, they last longer, cost less to power, and are safer than any other type of bulb.
Depending on how the light is powered, it is safe to leave led lights on for a week. If the led lights are screwed directly into a socket in the ceiling, it is fine to leave it on non stop for an entire week as there will be no fire risk.
In as much as the LEDs are the safest lighting options, there are cautions you should take, especially if you are dealing with low quality and cheap LEDs. These types are known to have a reduced heat dissipation capability. If left unattended for a long time, the LEDs could get hot, and probably start a fire.
In a single word, no. Even if left on for a longer period, led lights do not get hot enough to start a fire, as they are the type of bulb that uses the least amount of energy, and would not create enough heat to set nearby flammable materials such as paper on fire.
It is your decision whether led lights stay on or are switched off. Unlike other lights, led bulbs do not need a few minutes to become bright enough to use, so it makes sense to turn any light off when it is not in use.

Why do people turn on red lights at night?
To help quiet the mind and doze off, some people are turning on red lights at night as a helpful aid that could make snooze time longer.
Blue light, the type that comes from electronic devices, has shorter wavelengths (450 and 495 nm). Blue light has been implicated in keeping us awake at night —that’s why experts recommend turning off your devices well before bedtime.
A study in the Journal of Athletic Training found that 30 minutes of red-light exposure improved sleep and melatonin levels. Some other research suggests that red light therapy at night may also help you wake up more alert and ready for the day. A study in the Journal of Nature and Science of Sleep found that red lights prevented “sleep inertia.”.
