Taking a shower before bed can throw off your internal clock.
Do not think that we are saying you can never shower before bed. A hot soak in a bath is a great way to relax your body so that you can get ready for bed. However, if you shower more often in the evening, you are sending your body the wrong message; it will think that it is time to start the day. Only take a shower before bed if you have to. For instance, if you had a long workout earlier, or you just got grimy. However, don’t switch back and forth randomly between daytime and nighttime showering, as your body will only get confused. A consistent overall routine can aid in your sleep patterns.
