Work-Life Balance Definition
The Cambridge dictionary defines work-life balance as "the amount of time you spend doing your job compared with the amount of time you spend with your family and doing things you enjoy." This definition can be flexible based on your job, where you work, and how you work. For example, when you're working from home, it can be harder to identify when you're doing "work" and when you've transitioned into the "life" section. But regardless of the definition, when work-life balance is in an ideal state, you're centered, avoiding burnout, have low stress levels, and are able to perform at your best inside and outside of the office. However, we all know that this is a very elusive state, and often tricky to achieve actual balance between your professional and personal life.
The Issues That Arise
If you spend too much time working and too little time tending to your mental and emotional health, you're putting yourself at risk. You're risking burnout, which is now a condition defined by the World Health Organization as a "syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed." You're also likely not giving your body enough time to physical rest, sleep, and recover after work. A lack of sleep not only limits your productivity in the days after, but when you're regularly not getting enough sleep, your life expectancy can even be shortened.
