Night Shift feature on iPhone (Image: The Verge) In the description, Apple says that the Night Shift feature on its mobile devices “can help users sleep better”. The reason given by the company is that when the user turns on this feature, the light from the screen will turn into “blue light” thereby helping the user to easily fall asleep. But in a recent study shows the exact opposite, not only does it not make the user sleep easily, this mode also makes the quality of the user’s sleep worse. The study, published in the journal Sleep Health, tracked the sleep of 167 people for a week. These people are divided into three groups: one that uses a phone with Night Shift on for an hour before bed, one group does the same but does not have Night Shift on, and a group does not use a phone at all. before sleep. “There is no difference between the three groups,” said Chad Jensen, “there are even people for whom having Night Shift turned on isn’t as good as using a phone without having that feature activated.” This result is in line with early skepticism that the Night Shift feature isn’t really helping to improve the quality of a user’s sleep, especially since Apple doesn’t announce which wavelengths of light will be blocked when the user turns it on. this feature. While blue light and using your phone before bed can reduce the quality of your sleep, there are still many other variables that need to be considered. The researchers are also quite surprised when the group of people who do not use their phones before bed is not sure to have a perfect sleep. Before the experiment, Jesen and colleagues determined that they had to see the best sleep on the off-phone group, then the group that turned on Night Shift and finally the group turned it off. “But we were a bit surprised that the results were not what we expected.” This was especially true of university student participants who had a pre-existing sleep deprivation. “When people are already very sleepy, whether or not they use their phone before bed is not so important anymore. Since your needs are so high at that stage, you will fall asleep quite easily. whether you turn Night Shift on or off or even use the phone “. Jasen shares. The small differences related to cell phone usage observed by the research team were related to the amount of sleep the participants had. Among students who slept more than 7 hours, those who did not use their phones slept better and woke less in the middle of the night than those who used the phone before bed. But for those who slept less than 7 hours, there was no difference in sleep quality, regardless of whether they used the phone before bed or not. To explain this bizarre phenomenon, Jensen lists a myriad of factors that can affect your sleep apart from using your phone, such as caffeine use, exercise, temperature, and amount of light. , noise, bedtime … Results show that it is not only blue light that causes difficulty sleeping. Your psychological, emotional, and well-being will also affect the quality of your sleep. Raj Dasgupta, a sleep medicine specialist at the University of Southern California, said: “Sleep is such a personalized element that there won’t be one feature that will suit everyone. are more sensitive to light and may find blue light filtering helpful, but that won’t be the only solution to better sleep for others. ” For phones, there’s more to consider than blue light exposure, according to Jensen. “All other non-light stimuli can affect the quality of your sleep. If you’re reading a boring article or watching a funny video on TikTok before bed, That level of alertness and interaction will probably interfere with your ability to fall asleep. Blue light filtering now won’t compensate for that effect. “

KTS AD + studio said that when receiving the project, the architect realized many disadvantages in the construction context. First, the project is located on the ramp that connects two major roads in the area and has no setback space.

Second, the three sides around the house are obscured by neighboring houses with an average height of three stories. The third is to ask the landlord to wish to arrange multiple private rooms for a family of five in limited space of 36 m².

The architect has overcome the limitation of the location of the project to ensure there is a separate function room for a family of five.

With a high usage density of 10 main spaces including five bedrooms and a number of extra spaces just arranged around the traffic axis.

First, KTS AD + studio offers a solution to divide the building into two parts by height, pushing back the upper architectural block backwards.

This setback will change the elevation of the front façade, the rear part not visible from the street, keeping the house in the neighborhood proportionally.

The recoil of the above volume also increases the natural contact area for the stratosphere, optimally exploiting the light from the east façade.

The architect pushed back the upper architectural block to the back of the house.

With a fairly narrow area, the architect designed a medium-sized kitchen that is arranged on the ground floor, enough for family use.

Functional space is pushed back.

The space in front of the house is planted with many trees.

Next, two floors are arranged in the middle and the end of the building. The rear floor is almost just the ventilation road, which helps to correct the angular ground. The main floor in the middle is only allowed to occupy a small area out of a total of 36 m² of floor area.

The SHIFT concept of functional space towards the East of the architect will create an oblique space, maximizing sunlight for the kitchen and dining area in the morning. This is the most active time of the day.

This procedure is also used for the rear floor clearance, increasing ventilation efficiency, taking in light, and at the same time unifying an overall architectural shape reaching forward.

Two floors are arranged in the middle and the bottom of the house.

A solution to compose the vertical space will not guarantee the intensity of the light, so the architect implements the concept of translating.

That is translating

The functional space faces east to create an oblique void, maximizing sunlight for the kitchen and dining area in the morning.

The stairs change flexibly according to the height and corresponding position between the floors, depending on the oblique direction of the floor pine core.

The ladder body and tread surface use a material that has partial light penetration, allowing light to creep in, creating a shadow effect on the surrounding surfaces.

The ladder body and tread have plenty of gaps to allow light to penetrate to create a shadow effect.

The bedroom has a large, well-ventilated door

KTS AD + studio shared: “The construction site is located next to Cholon, an area full of Chinese culture in Saigon.

With the effort to create a new architecture but not too unfamiliar with the surroundings, the combination of details, selection of materials, colors and decorative lines of the building are inspired by us. from this perspective. ”

Task Manager interface.

Turn off booting of some unnecessary programs

All you need is a built-in utility – Task Manager. This app isn’t just the place to stop nasty bots from refusing to shut down. The task manager can also help with boot time management. Open Task Manager by pressing Ctrl + Shift + Esc. Alternatively, press the Windows key, type “Task Manager” and select Task Manager from the search results that appear.

If Task Manager is in minimal view, click More details in the lower left of the window to see the full program.

In Expanded view, select the Startup tab. This section lists all the different third-party programs that are trying to launch at boot time. Virtually all of them can be turned off, but there are some possibilities you’ll want to leave them alone.

To figure out what to turn off and what to retain, see the Startup impact column. Any program classified as “High” or “Medium” must be a “candidate” for disabling. Some programs like sound card, password manager or something related to graphics card … must be kept. On the other hand, items like web browser helper or virtual private network (VPN) can wait to launch until you really need them.

To disable a program, select it, then at the bottom right of the window click the Disable button. Under the Status column you will now see that the program has moved from Enabled to Disabled. Continue as needed through the list of third-party programs.

Turn on Fast Startup

Windows 10 also has an option to start your computer faster, which is Fast Startup. When you turn on Fast Startup, Windows 10 automatically creates a Hibernate file for faster startup. How to enable “Fast Startup” as follows:

Step 1: Open “Control Panel”, then select “View by: Large icons”.

Step 2: Select the “Power Options” feature.

Step 3: Click “Choose what the power buttons do” in the left pane of the window.

Step 4: At the top, please click on the green text “Change settings that are currently unavailable”.

Step 5: Under “Shutdown settings”, check the box “Fast Startup”. Click “Save Changes” to save the settings on your machine.

Run Disk Cleanup and upgrade the drive

Alternatively, to add a bit more speed during boot time, you can also run Disk Cleanup. This will remove any junk files and make your SSD or hard drive work more efficiently.

If your computer is still using a mechanical drive, upgrade to an SSD card for faster boot. Installing an SSD is one of the simplest hardware upgrades you can make, and the difference it makes in terms of overall performance is impressive.

With these tips, you should see a significant improvement in your computer’s boot time, and the best part is that it doesn’t require any special third-party software downloads.
