Taking a shower before bed is a popular bedtime ritual for adults, but does it help us sleep better? Research shows that showering before bed may help improve sleep quality. This is due to the body's thermoregulation process, which regulates our sleep-wake cycle. Our internal body temperature signals to the brain that it's time to fall asleep. Taking a warm shower or bath for at least 10 minutes, one to two hours before bedtime, can help lower blood pressure and improve sleep quality. However, the temperature and timing of showers are important factors to consider, as extreme temperatures and showering right before bed may negatively impact sleep. While there is no definitive answer for everyone, individuals should do what suits their preferences and makes them feel their best.
| Characteristics | Values |

A warm shower before bed can help lower your blood pressure
Taking a warm shower before bed can help lower your blood pressure and improve your sleep. A warm shower stimulates blood circulation, which helps your body get rid of excess heat, allowing your temperature to drop after you get out. This is important because a decrease in core body temperature is necessary for sleep.
Research has shown that taking a warm shower or bath (around 40 to 42°C or 104 to 109°F) for at least 10 minutes, one to two hours before bedtime, can improve sleep quality. This timing gives the body enough time to reach the ideal temperature for sleep. While a warm shower can help lower blood pressure and improve sleep, it's important to avoid extremely hot showers, as these can cause dramatic changes in blood pressure, especially in older adults.
If you're an athlete, cold showers may be beneficial for better sleep. Cold water immersion after exercise can help lower core body temperature, reduce muscle stiffness, and decrease heart rate, all of which can contribute to improved sleep quality. However, cold showers may not be ideal for everyone, as they can stimulate the body and increase cortisol levels.
Ultimately, the ideal shower temperature and timing depend on individual preferences. Some people may prefer warm showers to relax and unwind before bed, while others may find that cold showers help them feel more refreshed and energized. It's essential to find what works best for you and incorporate it into your bedtime routine.

Showering impacts your body's thermoregulation process, helping to lower your body temperature
Taking a shower before bed can help you sleep better by impacting your body's thermoregulation process and lowering your body temperature. This process, also known as the sleep-wake cycle, relies on small changes in body temperature—just one to two degrees—to trigger sleep.
When you take a warm shower, your body temperature rises, and your blood flow is stimulated. This increased blood circulation helps your body release heat more quickly, allowing your temperature to drop after you get out. As a result, your body temperature decreases, signalling to your brain that it's time to fall asleep.
Research supports the idea that taking a warm shower or bath one to two hours before bedtime improves sleep quality. One study found that participants who soaked in a warm bath for 11 to 15 minutes before going to sleep experienced lower blood pressure, with some seeing a dip of up to 16 mm Hg. Another study of over 1,000 older adults found that those who took a hot bath before bedtime fell asleep faster than those who didn't.
While warm showers are generally recommended for better sleep, cold showers can also be beneficial in certain cases. Cold showers are known to reduce muscle stiffness, which may contribute to better sleep by reducing discomfort. Additionally, athletes may benefit from cold showers after evening exercise, as they can lead to a drop in core body temperature, fewer nighttime arousals, and a greater proportion of deep sleep in the first few hours. However, the stimulating properties of cold water can also raise cortisol and norepinephrine levels, which may not be ideal before bed.

Cold showers can help athletes reduce muscle stiffness and discomfort
Taking a shower before bed can affect your body temperature and, consequently, your sleep quality. Body temperature plays a significant role in the sleep-wake cycle, and our bodies naturally experience a decrease in core body temperature before sleep.
Cold showers can be especially beneficial for athletes in reducing muscle stiffness and discomfort. Cold water is an excellent anti-inflammatory, facilitating physical recovery. It is a common practice to apply ice to an injured area to prevent swelling, and cold showers work similarly, providing relief from inflammatory processes. Cold showers can also improve blood circulation by causing a gentle contraction of the blood vessels, allowing blood to flow properly and carry more oxygen and nutrients to the body's cells.
Additionally, cold water immersion can help attenuate muscle soreness, enabling athletes to perform at their peak. Research suggests that cold water immersion may help athletes' muscles recover from intense workouts more quickly than hot or neutral water interventions.
While cold showers offer these benefits, the stimulating properties of cold water may not improve sleep. Cold water immersion raises cortisol and norepinephrine levels, which can be counterproductive to relaxation before sleep.
Therefore, while cold showers can help athletes reduce muscle stiffness and discomfort, they may not directly contribute to better sleep. The decision to take a cold or hot shower depends on individual preferences and goals, with hot showers being more suitable for relaxation before sleep.
