Have you ever wondered when the best time to take a shower is? Some people swear by a morning shower to kickstart their day, while others prefer a nighttime cleanse to wash away the day´s stress. But what does science have to say about this? Let´s dive into the research and find out.

Understanding Our Body Clock

Before we delve into the specifics of showering, it´s essential to understand our body´s internal clock, also known as the circadian rhythm. This natural, internal process regulates the sleep-wake cycle and repeats roughly every 24 hours. It can influence sleep, feeding patterns, hormone production, and even body temperature.

Morning Showers: A Fresh Start to the Day

1. Boosts Alertness

If you´re not a morning person, a morning shower might be just what you need. The sudden exposure to cooler water (relative to your body temperature) can increase your alertness. When the cold water hits your body, your oxygen intake increases, your heart rate speeds up, and your metabolism gets a kick start. This reaction can help wake you up and make you more alert.

2. Enhances Skin Health

Morning showers can also be beneficial for your skin. When you sleep, your skin rebuilds its natural oils. Showering in the morning helps to clean off the excess fat, leaving your skin fresh and rejuvenated.

3. Promotes Productivity

A morning shower can also set a positive tone for the day. It can be a time to plan your day, reflect on your goals, and even spark creativity. A study published in the journal "Thinking & Reasoning" found that people were more creative when they were relaxed, like during a shower.

Night Showers: A Relaxing End to the Day

1. Aids in Sleep

On the other hand, a night shower has its own set of benefits. It can be a relaxing activity that prepares your body for sleep. According to the National Sleep Foundation, a warm shower or bath before bed can aid in sleep. The reason is that warm water can increase your body temperature, and the subsequent rapid cool-down period can help induce sleep.

2. Cleanses the Day´s Dirt

Showering at night can also be beneficial in washing off the dirt and pollutants that you´ve accumulated throughout the day. This not only keeps your skin clean but also prevents potential skin problems.

3. Reduces Bedtime Allergens

If you suffer from allergies, a nighttime shower might be best for you. It can help wash off allergens like pollen and dust that have collected on your skin and hair throughout the day, reducing your nighttime allergy symptoms.

What Does the Science Say?

The science behind when to shower—morning or night—doesn´t lean definitively in one direction. It largely depends on individual preferences and lifestyle. If you´re a morning person who needs a jolt of energy to start your day, a morning shower might be best. If you need a way to wind down after a long day, a nighttime shower could be the way to go.


In the end, whether you choose to shower in the morning or at night, both have their unique benefits. It´s all about what works best for you and your routine. The most important thing is to maintain good hygiene and enjoy the process. After all, a shower is not just about cleanliness—it´s also a moment of relaxation and rejuvenation in our busy lives. So, whether you´re an early bird or a night owl, embrace your shower routine and the benefits it brings.
