Sleeping in your basement is generally not recommended as it can be a more damp environment and potentially increase exposure to allergens or airborne particles. If you do choose to sleep in the basement, consider investing in an air purifier to reduce levels of these contaminants.  Additionally, try running a fan during the day to help circulate air and keep the area dry. Be sure to also check for any signs of mold or mildew growth and address these issues as soon as possible
