Workplace Health Tips
When you hear the words"workplace health", what do you think of it? Your associations with this phrase are most likely negative: stress, eyestrain, muscle soreness, etc. In fact, over eighty percent of workers complain of some type of health problem related to their job. But it doesn't have to be that way. Here are some simple tips on how to alleviate a few of the most common workplace ailments.
Stress:
You've susceptible to stress no matter what you job is. It's one of the toughest conditions to beat, and it' s also one of the most serious. The best thing you can do if you experience frequent or severe stress is to talk to your supervisor. There may be ways to rearrange your schedule or adjust your responsibilities so that you don't feel so overwhelmed. During the milder onset of stress, take repeated deep breaths, which will help you to calm down and confront the situation.
Eyestrain:
In addition to causing damage to the eyes, spending too much time in front of the computer can lead to headaches, muscle soreness, and general, irritability. To minimize these problems,remember to take regular breaks away from your computer. Experts recommend looking away from the screen for at least 20 seconds every 20 minutes. Also, ensure that your computer screen is clean and well positioned.
General Discomfort:
For those of us with office jobs, we spend most of our day sitting down. Remember to stand up, walk around, or take a short break so often to keep your muscles from becoming too tight.
