Make sure you follow a regular sleep pattern by going to bed and getting up about the same time. Computer screens can force you to concentrate for a long time, causing eye strain. Take an occasional break when you work on the computer. If your vision problems persist, have an eye exam to find out if lenses may improve your vision.
Tension related to everyday problems can cause headaches and even migraines.
It is important to take at least 30 minutes out of your busy day to relax. Stand up during a telephone conversation. Take a walk during your lunch time.
