Productivity crashes when you do. Sleep deprivation, poor nutrition, and a sedentary lifestyle can all contribute negatively to your health.
Simple truth? Take care of yourself, or your life will fall down around you.
Make sure you drink enough water and get enough sleep, as both are vital for attentiveness. Eat healthy foods, and make sure you move around a bit during the day. Just going for a little walk or working while standing for a bit can have a huge impact on your health.
Be sure to look after yourself—you can’t do anything if you aren’t healthy!
