Using dim, red or amber lighting in the hours before bed creates a relaxing atmosphere, making it easier to fall asleep and stay asleep.

They are commonly found in electronic devices and are best avoided before bedtime. Green Light: Although less disruptive than blue light, green light can still decrease melatonin production and should be used with caution.
While red light exposure before sleep may be beneficial, it can have the opposite effect when used during sleep. “Continuous exposure may increase microarousals and negatively affect sleep architecture and mood,” Dr. Prabhakar says. For better shuteye, shut off all the lights and sleep in total darkness.

Red light therapy uses low-wavelength red light to penetrate the skin at a cellular level. This process stimulates cellular activity, boosts circulation and enhances the production of collagen and elastin—two key components for maintaining firm, youthful skin.
There is often a misconception that SAD/energy lamps produce vitamin D, but that is incorrect!

LED lights and our devices do contain a significant amount of blue light (but with important caveats and qualifications - see below), and the concern is that excessive use during evening hours will cause our bodies to continue the production of melanopsin, making it harder to fall asleep naturally.
Set your phone timer to remind you to look away every 20 minutes at an object that is about 20 feet away for a full 20 seconds. How Is Digital Eye Strain Treated? A simple way to avoid sleep disruption and digital eye strain is to turn on night mode on our iPhone or Android devices.

The koala is famous for sleeping around 20-22 hours a day, which is about 90% of the day, due to their low-energy diet of eucalyptus leaves that requires extensive digestion. Other extremely sleepy animals include the sloth (up to 20 hours) and the brown bat (around 20 hours), with some snakes like the ball python also sleeping up to 23 hours daily.
Signs of poor core sleep (deep, restorative sleep) include waking up foggy, daytime fatigue/energy crashes, poor concentration, irritability, frequent illness, memory issues, and mood swings, indicating your brain and body aren't fully repairing and consolidating memories. You might also experience increased sugar cravings, slow muscle recovery, and a weakened immune system.
