Stress can do much more than make you lose sleep and eat all the wrong things. It can also cause hair loss, forgetfulness, and skin rashes. Here are the facts, courtesy of * Prolonged emotional or physical stress - including surgery or illness - can cause your hair to stop growing. When it falls out about three months later, it can lead to thinning hair. The fix: If you're losing hair due to stress, avoid dying or perming, drink plenty of water, and eat a healthy diet with lots of fruits, veggies and lean protein. You hair should grow back within nine months. However, you should also talk to your doctor to rule out thyroid problems. * Stress can also activate your skin's immune function, resulting in itchy, red rashes like dermatitis and psoriasis. The fix: Use hydrating skin lotions, and drink plenty of water. If that doesn't help, ask your doctor about using an over-the-counter or prescription antihistamine. * Another result of stress: Forgetfulness. When you're chronically stressed, the hormone cortisol can damage the hippocampus, the part of the brain responsible for learning and memory. The fix: Take control by making lists and keeping a calendar. The more organized you are, the less stressed you'll be. * Stress can also cause nail-biting - which doesn't just damage your nails. It can also lead to infection. The fix: When you feel anxious, substitute another activity, like squeezing a rubber ball. Chomping down on your nail transfers germs from your nail bed into your mouth, which could lead to infection. * High stress can increase your risk of a car accident, because stress affects your ability to concentrate and focus on the task at hand. The fix: Take a few deep breaths before your start the car, and remind yourself to focus on the road. Also, strictly obey the speed limit and other rules of the road, and always signal and check your mirrors before you change lanes. If you're too upset to drive safely - pull over until you can get a grip on yourself.
