What may be easy for some people, the noise, the normal day-to-day concerns of life, working, and new technology can be very difficult for returning soldiers. Often they have been in isolated areas of battle, away from normal society, and in foreign lands in foreign languages. Do not underestimate the strength of your soldier. They have been through hell and back!
Take time to let them adjust. Do not push, gently, and calmly let them find help. Work with your friends and family to get the support you need while your service man and woman find their feet. The crush of being in battle, being on threat 24/7, can make any one jumpy. The constant noise of children, pets, and TV, can be very unnerving for the human brain returning from a stressful and quiet place of battle. Battle can be noisy, but extremely quiet as well.
So, some advice: take some time to keep the news off, keep the TV off, just for a little while. Take some time for your children to find a great new activity at school, so they remain growing and learning, and then can give your soldier the much needed adjustment time.
Bells, whistles and any constant noise can be very unsettling for the returning hero. Keep a pace of calm and peace, whenever you can.
