You have trouble focusing your mind
If you are overwhelmed by many things and you are thinking about a lot of stuff at the same time, you will find it difficult to concentrate on anything. You will also become forgetful, such that you may even forget simple things like your colleague’s name.
You have probably noticed that many public speakers drink water when making presentations. This is because the mouth tends to become dry when one is under stress. This is as a result of essential body fluids being redirected to other important parts of the body, such as the heart, lungs and muscles. This results in body fluids being ‘lost’ in ‘non-essential’ areas of the body, such as the mouth and lips, hence the dry mouth.
If you have had a long, tiring day, it is only natural for you to fall asleep at night when you get in to bed. However, if you are constantly anxious and thinking about a lot of things, you will have trouble sleeping at night.
