Blue light has been getting such a bad rap especially in the context of sleep. Many believe that blue light gets in the way of having a good night sleep and causes a lot of tossing and turning at night.
But what is blue light and where can you get it? Can it really keep you from sleeping well? If so, what’s the explanation behind it?
Let’s get a bit nerdy and pretend we’re all back in physics class. To understand what blue light is, you need to know that light is composed of electromagnetic particles travelling in waves.
Blue light is part of a wide array of colors in this light spectrum seen by the naked eye (the others being violet, indigo, green, red, orange and yellow). It is a short wavelength so it produces higher amounts of energy.
According to studies, prolonged exposure to blue light can result in eyestrain, fatigue, headaches, long-term eye damage, and sleeplessness.
While present in sunlight, blue light also comes from digital screens. So when you stare at your computer screen at work the whole day, or spend hours on Instagram, then you may run the risk of suffering from the adverse effects of blue light. Here are the various sources of blue light:
Blue light wavelengths are all around us. If you’re wondering why the sky on a beautiful day is blue, then you can thank blue light for that.
Natural blue light is great for uplifting the mood, having an overall feeling of well-being, and regulating the circadian rhythm – or our body’s sleep and wake cycle. Blue light is also the reason why you feel so much more alert, energized, and mentally sharp during the day.
But it’s also the reason why you may be having a hard time falling asleep at night. Too much blue light may keep you wide awake and make it tricky to wind down.
Artificial blue light from electronic devices may mess up with your circadian rhythm, because it prevents your system to prepare for snooze time and slow down the production of melatonin, a hormone that helps you become more sleepy.
The problem of artificial blue light impeding sleep is unfortunately quite widespread. Just look at these stats from Blue Tech Lenses: 
Being exposed to blue light - especially at night - slows down the secretion of melatonin, which affects the sleep cycle. While melatonin is naturally produced, it can also be found in supplements.
The circadian rhythm – or the body’s internal clock – gets signal from the environment, usually in the form of light. The presence of blue light – whether during daytime or at night – affects this. Getting blue light during the day brings about alertness and general wellbeing. But at night, too much of it can keep you from having a proper snooze.
A study conducted at the University of Toronto compared the melatonin levels between people wearing blue-light goggles that exposed to bright lights indoor and those exposed to dim light sans goggles. The research is quite telling, in that the melatonin levels are just about the same between the two, showing that blue light suppresses melatonin secretion. 
Another study conducted by Harvard researchers showed a comparison between two groups - those exposed to blue light for 6.5 hours and another exposed to green light by as much the same brightness. The result showed that the first group suffered from suppressed melatonin secretion for about twice as long and had their circadian rhythm moved by twice as much as those in the green light group. 
There are also many other ways you can sleep better. Remember, blue light is only part of the story. Make sure that you supplement your blue light protection with proper diet, enough exercise, and other sleeping hacks.

Beginning an exercise program can be daunting, especially if you have never really been into fitness before.
Some people, when they exercise, strive for a bikini body. If you have a diving bell body, don't fret, you too can be helped by regular exercise. You can look better, but more important feel better if you eat right, exercise, and get enough sleep.

You've heard running can help you slim down, help maintain heart and lung health, and keep your body strong. Those benefits alone can help you feel well mentally.
But did you know that running can also help lift your mood and even ward off depression? It can help you be more creative and productive and feel less stressed out.
No wonder about 50 million Americans, or 15 percent of the population, jog or run regularly!

Whatever kind of intense exercise you do, whether running, weightlifting, team sports, or hard work, your body needs rest days.
In fact, Healthline says rest days are just as important as exercise days, and no regimen is complete without both exercise and rest. Rest enhances your energy and restores the body to full capacity.
