 You need to start showering at night. Showering before bed keeps the toxins, sweat, bacteria, and 60,000 types of germs you come into contact with daily out of your bed and off of your sheets. It can also help you fall asleep faster. When your body is curing up to fall asleep, it begins to cool down. A shower 90 minutes before you hit the hay can help speed up the cool down process, sending you into dreamland quicker. Night showers can also help relax your muscles, which aids in better quality sleep.
