Surprised I couldn't find an entry for this in Wikipedia.

What is it? It's when you tend to get sick on weekends and on holidays.

An article from Guardian UK elaborates on it more.

Getting sick or just feeling tired doesn't help reduce stress, as work just piles up if you don't recover by the time the week start.  If you're an IT worker, if you're tired, you just can't think and that is a major productivity killer.

For me this mostly started after having kid, I just didn't have any chillout time, and if I did, it ended up being exhausting rather than relaxing.

I already started one of their suggestions which is to ensure you do something to relax/calm down on Fridays. A partial solution for me is to regularly schedule Friday evenings for basketball, followed by a massage.

On massages

For me due to sports, I usually associate massage with physiotherapy. Reading some local cartoons such as "Durian Life or Lat", I often see that in Malaysia massage has sexual connotations eg. massage parlor. Possibly it's why people think it's not a good idea. Trust me on this, if you're having headaches and are stressed out, arrange an appointment it will work wonders.

What you should look for is so call "Blind Massage" centers in your local neighbourhood commerical area. These are clean, simple establishments run by blind people and it's male to male and female to female. It's about RM30-40 per hour for full body massage. I suggest you chose the pressure point (or shiatsu) option, as you will not need to take any clothing off for those that have reservations. Not only is it a good way to relieve stress, you're also helping out the local blind community businesses. It's also a good way for IT people to better understand why accessibility is important.
