According to the National Blood Clot Alliance, certain activities are not beneficial for DVT. For example, people should aim to avoid sitting for periods of 2 hours or more at a time. Getting up regularly to move and stretch can help. If people are traveling, they can stop roughly every hour to walk for several minutes or walk about on a plane to stretch their legs. Wearing compression stockings when traveling can also help. People will also need to avoid crossing their legs when sitting, as this can negatively affect circulation. It is also important to avoid dehydration, so people should drink plenty of fluids, such as water, throughout the day.
