If I sit at my desk for too long and then stand up, my knees feel really stiff. What causes this?

Question

I am 25 years old and in good health.

Answer 1

I do believe that the circulation of blood is being cut off in your legs. ;)

You can address this with a new chair. It sounds like the chair is too short in the seat (stops about mid thigh) and cuts off the circulation to your lower legs. A good chair depth is 2-3 fingers from the front of the chair to the back of the knee.

If that is not possible, get up every hour or so and strech. My knees hurt after 10 minutes in a chair so I have to get up and stretch once every hour.

Answer 2

Sitting at your desk for a long time is what causes that your just stiff from not moving.

Answer 3

For every 55 minutes you sit you should get up and move around for at least 5 minutes. While sitting don't sit in one positon for too long. Move your legs or shake them or something. Keep the blood circulating.

Answer 4

The blood in your legs are not circulating properly. Get up and walk around to the bathroom are someplace sitting to long will cause this to happen.

Answer 5

Sitting at your desk too long. Get up and move around.

Answer 6

You need to take breaks like walk around to get that circulation rolling. flex your legs, your muscles, do squats and then go back to your exciting desk.

Answer 7

NO circulation getting to your legs aka your legs are asleep

Answer 8

drink more water. It not only loosens your joints but moistens your lungs and is actually beneficial to all of your organs.

Answer 9

May be the beginnings of osteo-arthritis. I got it about then.
