The timing of your shower can affect your sleep and energy levels in different ways.
Sleep researchers say warm nighttime showers work best if you're having trouble sleeping. Taking a warm shower one to two hours before bed helps your body temperature drop, which signals your brain it's time to sleep. This matches your natural body clock and can help you fall asleep faster and sleep better.
Evening showers also have a creative bonus. When your mind is relaxed, you might come up with new ideas or solutions to problems you've been thinking about. The best choice depends on what you want.
If you need better sleep, try warm evening showers.
If you want more energy in the morning, cold morning showers work well.
