Additional tip:

Avoid using devices in bed

Most people do not realize how using a phone, computer or tablet in bed affects their sleep and productivity. Short wavelength blue light affects your mood, quality of sleep and energy levels. In the morning, the sun produces a high concentration of short wavelength blue light.

When your eyes get exposed to the blue light, the self-inducing hormone, melatonin stops being produced and you become very alert. In the afternoon, the sun stops producing the blue light. And your body starts producing melatonin which starts making you sleepy.

Most of the devices we use emit short wavelength blue light right in your face. The exposure impairs the production of melatonin thus interfering with your ability to fall asleep and the quality of your sleep once you start doze off. And poor sleep will affect everything you do the entire next day. To break this habit, avoid using your phone, tablet or computer after dinner.
