WASHINGTON DC. [USA]: Nowadays, we all know that spending too much time watching screens – be it computers, phones, iPads – disrupts sleep. But do you know why?
Researchers have identified how certain cells in the eye process ambient light and reset our internal clocks, the daily cycles of physiological processes known as circadian rhythms. When these cells are exposed to artificial light late at night, our internal clocks can be disrupted, resulting in many health problems.
The study, conducted by researchers from the Salk Institute, was published in the journal Cell Reports.
The results could contribute to the development of new treatments for migraines, insomnia, jet lag and circadian rhythm disorders, including cognitive disorders, cancer, obesity, resistance to insulin, metabolic syndrome
"We are continually exposed to artificial light, whether it's time spent in front of the screen, spending the day indoors or staying awake late at night," said Professor Salk, Satchin Panda , lead author of the study. "This lifestyle disrupts our circadian rhythms and has deleterious health consequences."
Sleep like a baby! Six technologies to make your room more comfortable
For a good sleep!

Technology that is an integral part of our daily lives can not only brighten up our bedrooms, but also improve the way we sleep at night.
Bedroom monitor and sleep sensor
August 9, 2017
This beautiful little ball – Sense with Voice of the second generation of Hello – has everything to help you sleep better. Besides the measurement of light, humidity, temperature, air quality and noise, the device can now detect volatile organic compounds such as CO2, levels UV in the room and barometric pressure. Its Sleep Pill button attaches to your pillow to monitor your movements overnight and sends this data to the Sense app for analysis.

Make sure your clothes are tracking your sleep
August 9, 2017
The bands to wear are not just follow-up activities. The lightweight and stylish Jawbone UP3 is designed to give you the benefits of tracking your sleep and a complete picture of your hearing, beyond your daily activities. It tracks your sleep by automatically measuring Deep, Light and REM (quick eye movements) and offers tips to help you sleep well at night.

Wake up light
August 9, 2017
Daily light therapy with a Philips morning wake-up light can change the way you start the day. This light alarm concept uses a colorful simulation of the sunrise with sound. It gradually brightens from soft morning red to orange until your room is filled with a bright yellow light. The process of increasing light change, according to society, stimulates your body to wake up naturally.

The wardrobes are outdated. Give your room a smart clothing management system that not only houses your clothes, but also refreshes them. The LG Styler reduces wrinkles and eliminates odors from your clothes, reducing the frequency of their trips to the cleaner. Hot steam is used to refresh and remove wrinkles and odors from clothes.

The back of our eyes contains a sensory membrane called the retina, whose innermost layer contains a tiny population of light-sensitive cells that function like pixels in a digital camera. When these cells are exposed to continuous light, a protein called melanopsin continually regenerates within them, signaling ambient light levels directly to the brain to regulate consciousness, sleep, and alertness. Melanopsin plays a vital role in synchronizing our internal clock after 10 minutes of illumination and removes, under bright light, the hormone melatonin, responsible for regulating sleep.
"Compared to other photocells in the eye, melanopsin cells react as long as the light lasts, even a few more seconds," said Ludovic Mure, first author of the article. "It's essential because our circadian clocks are designed to respond only to prolonged illumination."
In the new work, Salk researchers used molecular tools to activate melanopsin production in retinal cells in mice. They discovered that some of these cells were able to maintain bright responses when they were exposed to repeated long pulses of light, while others became insensitive.
Conventional wisdom has argued that proteins called arrestins, which stop the activity of certain receptors, should stop the photosensitive response of cells a few seconds after illumination. The researchers were surprised to find that the arrestins are in fact necessary for melanopsin to continue to react to prolonged illumination.
In mice lacking one or the other version of the arrestin protein (beta-arrestin 1 and beta-arrestin 2), retinal melanopsin-producing cells failed to maintain their sensitivity in the light under prolonged lighting. It turns out that the reason is that the stopin helps melanopsin to regenerate in the retinal cells.
"Our study suggests that both arrestines perform the regeneration of melanopsin in a particular way," Panda said. "One artery does its conventional job of stopping the response, and the other helps the melanopsin protein to reload its co-factor for retinal light detection." When these two steps are performed in rapid succession, the cell appears to react in permanence in the light. "
By better understanding the interactions of melanopsin in the body and how the eyes respond to light, Panda hopes to find new targets to counter asymmetric circadian rhythms due to, for example, artificial illumination. Previously, the Panda research team had discovered that chemicals called opsinamides could block the activity of melanopsin in mice without affecting their vision, thus providing a potential therapeutic track to fight against. hypersensitivity to light experienced by migraine sufferers.
Do you often feel tired? Include these foods in your diet to stay energized

Low immunity and energy that weighs on your health?
We often tend to become less active because of time changes. After a busy schedule, we are often deprived of "free time", following which we resort to an unhealthy diet.
Good nutrition, lots of water and an active lifestyle are some of the habits you should adopt this season, as well as the following tips:
Start your mornings with muesli
July 28, 2018
Keeping your belly full and nurtured is very important. Start your mornings with muesli to be energetic all day long!
Muesli is a healthy blend of rolled oats, wheat flakes and corn flakes of various flavors. It is rich in dietary fiber, protein, iron and antioxidants.
Go green
July 28, 2018
Say no to sugary and carbonated drinks, and opt for a cup of hot green tea instead. Filled with powerful antioxidants and nutrients, green tea helps regulate blood sugar, improve brain function and improve metabolism.
This drink also helps to increase the detoxification process in the body and to promote weight loss.
Add a pinch of honey, squeeze a lemon into your green tea cup and make your day a tasty affair!
Multifloral honey
July 28, 2018
This blend of sugar, oligo-enzymes, minerals, vitamins and amino acids is unlike any other sweetener on the planet. Honey is a great substitute for sugar and helps manage calories while adding many healthy nutrients instead of empty calories.
For a nutritious and satisfying meal, pour multifloral honey over a bowl of skim milk muesli.
Drink for all seasons
July 28, 2018
An important habit is to stay well hydrated. If you have trouble drinking plain water, you can try adding lemon or fresh fruit to the water. Water is important for keeping the immune system healthy and eliminating toxins.
