How do electronics keep time when off

Most electronics with internal clocks keep them regulated via vibrating crystals much Most electronics with internal clocks keep them regulated via vibrating crystals much like a quartz clock that keep their timekeeping precise. But while far better timekeepers than mechanical clocks, even these crystals can be thrown off their regular frequencies by external factors like humidity or temperature.

But artificial lighting is all around us, and it to is a fantastic keeper or time. Alternating current provided by power mains runs at a frequency of 50 or 60 cycles per second, with the power delivered dropping to zero twice per cycle. Sounds and blinking lights can cause unwanted awakenings when sleeping next to electronics. The blue light emitted by many devices disrupts the natural production of melatonin , a hormone that facilitates sleep and can throw off your circadian rhythm.

As a result, the first step is to take an inventory of the technology in your home and bedroom, including these devices: Televisions Cell phones Tablets Desktop and laptop computers Video game consoles E-readers Smartwatches Smart home hubs like an Amazon Echo or Google Home device The way that you interact with each of these devices can vary, and they also have different timetables for charging. Tips for Making Your Bedroom Technology-Free The most obvious way to foster a technology-free sleep environment is to simply remove your devices from the bedroom.

Create a dedicated space for electronics: Find a spot outside the bedroom where you can park all of your electronics during the night. This is an ideal place to put chargers so that all your devices will have a full battery in the morning. Instead, include steps that are practical, like putting on pajamas, and relaxing, like stretching or reading in dim light. It also helps you get used to a set period without screen time and promotes a regular sleep schedule.

Keep something to read nearby: Reducing nightly screen time is a great way to recapture the joy of reading a printed book or magazine. This allows your brain to associate being in bed with those activities, minimizing the urge to bring technology into bed with you. Use a basic alarm clock : If you use your phone as an alarm, a basic alarm clock can take its place and make sure you wake up on time.

Most alarm clocks have settings for low brightness to help keep your bedroom dark. Consider a white noise machine : If you use your phone to play soothing sounds at night, a white noise machine can serve the same purpose but without putting email and messages right at your fingertips.

Set boundaries with friends, family, and work: Many people think they need to sleep with their phone nearby because they may have to immediately respond to something important. Setting this boundary gives you the freedom to make your bedroom technology-free without worrying about missed messages, calls, or emails. Reward yourself: If removing technology from your bedroom feels like punishment, find a way to turn it into a positive, rewarding yourself for certain milestones, such as one week, one month, or one year of having a technology-free sleep environment.

The blue light emitted by your cell phone screen restrains the production of melatonin, the hormone that controls your sleep-wake cycle aka circadian rhythm.

This makes it even more difficult to fall asleep and wake up the next day. The circadian rhythm seems to be especially sensitive to blue light since it has a short wavelength. Studies also show that exposure to blue light can cause damage to your retinas. Even if it's not upsetting content, keeping your mind engaged by scrolling through your phone can trick your brain into thinking it needs to stay awake.

Since you spent that extra time staying awake reading emails instead of sleeping, now you're going to be more tired and less alert for the next day. And who wants to be less aware and more sluggish throughout the day? Aside from the fact that late-night scrolling can make you less efficient, it can also lead to a significant and chronic deficiency in sleep.

Because even though you may not be on it, the text alerts, game notifications or email buzzes can interrupt your deep sleep. Here are some tips and advice to help you get to sleep without your handy sidekick.
