On the weekend most people want to just kick back and relax. Instead most are running around doing errands, cleaning the house, food shopping, etc. Your body and mind need downtime other then watching TV or sleeping. So turn off the TV, Computer, Radio and any other electronic device. The more you unplug the more time you will find to let your body and mind reconnect. This connection is very important for downtime. A nice quiet walk is a great way to relax, mediatation works or even just go out and look at the stars like we did as kids.
If you do any of these things and do not set a time on how long you are going to do them you will notice a big difference in your stress levels.
