Compression socks, which increase blood circulation, could be used to help improve obstructive sleep apnoea.
A new study found that the socks can help people with obstructive sleep apnoea who also suffer from a condition known as chronic venous insufficiency (CVI), when the veins cannot pump enough blood back to the heart
The researchers tested the socks on twelve people with both CVI and obstructive sleep apnoea. They spent one week wearing the socks and a second week without them, to test whether they made a difference.
The results showed that by reducing the fluid in the legs, the socks were able to also reduce fluid flowing into the neck at night, which can cause disruption for people with sleep apnoea.
After wearing the compression socks, people had an average of a 62% reduction in overnight leg fluid volume compared to when they did not wear the socks. Participants also had a 60%reduction in neck circumference increase and a 36% reduction in the number of interruptions caused by having obstructive sleep apnoea, per hour of sleep.
