If the purpose of your bath is to relax, then bright, overhead lights and the sounds of arguing neighbors shan't help you unwind. Dim the lights or light a few candles in the bathroom. Turn on calming music, like a classical station or some ambient noise, such as ocean waves or bird calls.  If your bath has a curtain, draw it all the way or part-way to trap steam and heat. Just make sure the curtain is not in the bathtub with you. If you have a heater in the bathroom, turn it on to make sure the temperature outside the bath water isn't jarringly cold. Running the bath with the bathroom door closed can also help create a warm environment. Ensure the heater doesn't get wet. Don't use electronics in the tub. This can be dangerous (and potentially deadly). And while your phone or e-reader probably won't electrocute you if you drop it in the tub, it will be ruined. Be careful if you use candles. They could fall over during your bath and burn something. Don't put unsecured candles near the tub. Bring a magazine or book to read. Paperbacks are easier in the bath than heavy, hardback books. Personalize your bathing experience by adding fun bubbles or bath bombs; essential oils for aromatherapy and to keep skin moisturized; or things like Epsom salts, honey, or oatmeal to soothe or heal skin and muscles.  Add oils or other extras when the tub is halfway full to ensure they disperse evenly throughout the water.  Use at least an entire cup of oil per bath to reap the moisturizing benefits. Now is a great time to really pamper yourself. Exfoliate your body with a sugar scrub. Apply a mud or face mask and lay slices of cucumber over your eyes to soothe and de-puff. Try an oil hair treatment and deep condition your hair.  Try a hydrating mask if your skin is dry or you're worried about it drying out in the bath. Use a clay mask for super smooth skin. These are great if you have large pores or oily skin Tea tree oil can help treat dandruff and moisturize dry hair. Try just a little Moroccan oil on your hair for silky, not...
