Everyone has bad days at work, but there are signs that employees need to watch out for before a bad week at the office turns into never-ending, debilitating work stress that is ruining your health.

Too many Americans are trapped in toxic jobs, a problem employers and employees need to take more seriously. Jeffrey Pfeffer, an organizational behavior professor at Stanford who wrote the book Dying for a Paycheck, found through his research that poor management in U.S. companies accounted for up to 8 percent of annual health costs and was associated with 120,000 excess deaths every year.

If you want to be taken seriously and if you wish to get ahead in your career, you must learn how to behave professionally in your workplace. This is nothing new. Yet many people fail miserably in modeling professionalism at work. This happens because people generally don’t understand the significance of demonstrating professionalism in the workplace and the role it plays in determining the amount of success they manage to garner in their lives. Those who truly understand its value would want to work on improving themselves so as to be more professional at work.

Happiness looks different for everyone. For you, maybe it’s being at peace with who you are. Or having a secure network of friends who accept you unconditionally. Or the freedom to pursue your deepest dreams. Regardless of your version of true happiness, living a happier, more satisfied life is within reach. A few tweaks to your regular habits can help you get there. Habits matter. If you’ve ever tried breaking a bad habit, you know all too well how engrained they are.

Take a deep breath. Hold it for a moment, and then exhale. Feel more relaxed? Breathing exercises are one way to relax. Here you will learn about different ways to relax your mind and body. Being relaxed can help ease stress. It can also relieve anxiety, depression, and sleep problems.

Worry is a normal reaction to a stressful or troubling event, and it usually goes away on its own. But what happens when the worry doesn’t go away? Some people worry all the time—even when everything is okay. They might feel like their worry is out of control or feel like they just can't stop their worried thoughts. Others don’t notice their problem with constant worry until they feel physical signs of stress, like headaches, stomach aches, muscle tension and fatigue. We all worry sometimes. But if you seem to worry much more than other people and you worry so much that it affects the quality of your life, you may have something called generalized anxiety disorder.
