If you don't disturb others, it's a good idea to sit and elevate your legs to prevent varicose veins. Varicose veins are a condition where blood pools and swells in the leg veins. Sitting in one position for long periods of time can impede blood flow in the legs, making varicose veins more likely to develop. Elevating your legs stimulates circulation in the lower body and loosens up swollen leg muscles. Elevating your legs also relieves pressure on the blood vessels in your legs, improving blood flow to the brain.
Stretching while seated is also beneficial. Professor Kim Jeong-hyeon of the Department of Sports Medicine at Kyung Hee University said in a past interview with Health Chosun, "If you sit in a chair for long periods of time, you should take 10 to 15 minutes every hour to move your body. Moving your body improves blood circulation and has a positive effect of waking up the body."
A good place to stretch first is the hamstrings at the back of your thighs. Just sit on a chair, straighten your back, tuck your chin in, place your feet together, and stretch one leg out in front of you. It is good to slowly move your legs back into place and do it with both legs. There are also exercises that target the piriformis, the muscle that stabilizes the hip joint. Sit on a chair, straighten your back, and place one leg over the other. Place both hands on your ankles and knees to stabilize them, then bend your upper body.

It's also essential to develop the habit of drinking water regularly. Dehydration can cause blood to become sticky and impede circulation. Drinking water increases the amount of blood and lymph, promoting circulation. Stretching can also help loosen stiff joints and muscles.
