Have you heard of the many supposed benefits of drinking ice water before bed to lose weight?
If so, you may wonder if these claims are valid and how to incorporate them into your routine.
In this article, we will dive deeper into the potential benefits of drinking cold water before bed and if this practice will help you to lose weight.
Overall, drinking cold water before bed can indirectly aid with weight loss. More specifically, according to a systematic review published in 2019, drinking water can aid in weight loss most when water is used to replace caloric beverages, such as soda, juice, lemonade, and more. [1]
However, the weight loss benefits of drinking cold water before bed are no different than drinking water at any temperature at any other time of the day.
In fact, no scientific studies or research articles exist on the specific effect or benefit of cold water consumption over different temperatures.
Therefore, drink cold water at night if you prefer, but there is no need to drink iced water right before bed for weight loss.
If you consume high amounts of sodium during the day or do not drink adequate amounts of water throughout the day, you may feel increased thirst at the end of the day.
Additionally, if you participated in an intense exercise in which you sweat excessively, you may also feel increased thirst due to water loss.
Let’s discuss the potential benefits and consequences of drinking water before bed.
Drinking water benefits overall health, weight loss, and more. However, no studies focus on drinking water specifically before bed. Therefore, in this section, we will discuss the potential benefits of drinking water at any temperature and any time of the day.
According to the Centers for Disease Control and Prevention (CDC), drinking water can help the following [2]:
In other words, adequate water consumption is essential for your body systems (such as the excretory, nervous, or skeletal systems) to function at their best.
To increase your water consumption, here are a few simple tips:
Drinking water before bed can cause sleep issues since you may wake up in the middle of the night to use the bathroom. The effect of water on your bathroom habits can depend on how much water you drink and at what time before bed you consume it.
Therefore, it is best to avoid drinking large amounts of water within a few hours before bedtime. However, this will differ from person to person, so look for patterns in your urinary habits at night depending on how much water you drink before bed.
It’s best, therefore, to drink water throughout the day so you’re not playing catch-up right before bedtime.
So, what about drinking water for weight loss? Whether you are drinking cold, room temperature, or warm water to lose weight, increased water consumption has many potential indirect benefits to weight loss.
Here are some ways drinking water can aid in weight management.
Drinking water can help you reduce caloric intake if you are accustomed to having sugary and high-calorie beverages throughout the day instead. For reference, a 12-fluid-ounce serving of soda can contain approximately 150 calories. [3]
Imagine you are drinking one with each meal each day for seven days. That’s about 3000 extra calories consumed per week! Therefore, having just one less sugary beverage each day, such as soda, juice, lemonade, energy drinks, and sweet teas, can significantly benefit weight loss.
Interestingly, the effects mentioned above were also found in a study published in the International Journal of Obesity. This study compared the weight loss effects of substituting water for diet beverages. [4]
Researchers saw more significant weight loss when diet beverages, such as diet soda, were replaced with water after the main meal of the day. Therefore, you can also swap out your diet soda with water or unsweetened tea.
Drinking adequate amounts of water throughout the day can help to prevent dehydration.. A 2016 study published in the Annals of Family Medicine also found that adults who did not consume enough water had a higher body mass index (BMI) and a higher incidence of obesity. [5]
Therefore, reducing dehydration may provide benefits to your weight.
Symptoms of dehydration include mood disruption, constipation, overheating, altered mental status, and more. Therefore, drinking enough water is very important.
Experiencing intense exercise with sweating, vomiting or diarrhea, or fever will further increase your body’s water needs, so make sure to stay hydrated in these situations. Speak with your physician or registered dietitian if you are concerned about your hydration status and for personalized fluid recommendations.
