You should generally avoid wearing compression socks at night because when lying down, your body's legs are horizontal and gravity no longer impedes blood flow, so the extra pressure from the socks is not needed. Wearing them unnecessarily at night may cause skin irritation, restricted blood flow if they are too tight or ill-fitting, nerve pressure, discomfort, and in some cases, skin breakdown or infection from trapped moisture. Additionally, people with certain conditions like peripheral artery disease, uncontrolled diabetes, or neuropathy may experience worsened circulation or complications by wearing compression socks while sleeping. If compression socks are recommended at night by a doctor, they usually advise using a mild compression level and ensuring the socks fit properly to avoid these risks.
In summary, compression socks are primarily designed for use during the day to support venous return against gravity. At night, since gravity’s effect is less, wearing compression socks without medical advice can lead to discomfort or health risks rather than benefits.
