Avoid taking sides if tempers flare. Instead of a traditional family holiday weekend, consider only a brunch. Avoid sensitive topics. Although most people prefer to be themselves, holiday stress tends to bring out sensitivities. Limit alcohol consumption.
Alcohol can cause unpredictable behavior when used in excess.
Alternating the location of family get-togethers or who's responsible for cooking, decorating, photography and cleaning could make the holidays more fun and less stressful for everyone. Take care of yourself. Plenty of sleep, a healthy diet and regular exercise can help reduce stress. When it comes to holiday stress and family tensions, an ounce of prevention is worth a pound of therapy.
