We take home stress to work and workplace stress home with us, and the two can exacerbate each other. Imagine this scenario. You have an argument with your partner one morning and then go to work. When you arrive, you find out that one of your team hasn't finished their work, and you get very angry with them. Equally, you may find that if you have a particularly bad day at work, that you take this stress home with you and take it out on your family. These examples are quite simplistic, and the effects of stress are often more subtle and the boundaries between workplace and home stress more blurred.
We can learn highly effective stress-management techniques and exercises to cope with both but we must keep being honest with ourselves and trusting others. It is common to act defensively when someone tells us we're stressed, and often we don't want to admit that we're suffering from stress. But if a trusted friend or confidant tells you that you're stressed, listen to them, and take the opportunity to reflect inwardly on this.
Stress is a medical condition and it can have a serious effect on your health. If you think you are suffering from stress it is crucial that you consult a medical professional.
