We all know that sitting in a Office Chair Singapore all day is bad for your health, especially your back. But why is this? Well, humans were not designed to sit in the position that most non-ergonomic chairs put us in. Our backs have been evolved for a hunter-gatherer type lifestyle, in fact, there are very few complaints from tribe’s people today about back pain, somewhat proving the theory.Typically the wrong Office Chair Singapore puts your back in a straight position when it should in fact curve inwards. As your weight bears down on your pelvis the Office Chair Singapore pushes the base of the pelvis up. This pressure causes your spine to bend forward into an unnatural position and puts a strain on to your ligaments.Most people tend to naturally slouch over or down in their Office Chair Singapore, this worsens the situation. After extended periods of time, this pressure builds up and you start to ache. This is why it is important to stand and stretch regularly (at least once an hour) and take short breaks often.SymptomsThere are many symptoms of back pain caused from sitting, these include:- An achy, dull pain and soreness- Difficulty moving with ease- Pain that spreads to the groin, buttocks and upper thighs- Muscle spasmsPain can be ongoing for days or weeks before easing and can sometimes be just as bad, if not worse in the legs and feet. You may also suffer from other symptoms such as numbness and weakness too. These symptoms are the same as you would get after driving a long distance or flying long haul. The cause is all the same, sitting for too long.
