Is it better to drink cold water or room temperature water when you wake up?

4 min read

According to Medical News Today, there is little scientific evidence suggesting that drinking cold water is bad for you. However, when asking if it is better to drink cold water or room temperature water when you wake up, the answer depends largely on personal preference and health goals. The first glass of the day is crucial for rehydrating your body after a night's sleep, but the temperature can influence how you feel.

Quick Summary

This article examines the comparative benefits of drinking cold versus room temperature water first thing in the morning. It details how temperature affects hydration speed, digestion, metabolism, and alertness, providing guidance to help you choose the best option based on your personal health needs and goals.

Key Points

  • Gentle on Digestion: Room temperature water is easier on the digestive system and promotes smoother nutrient absorption.

  • Refreshing Jolt: Cold water provides an invigorating sensation that can increase alertness and boost energy levels in the morning.

  • Quick Rehydration: The body can absorb room temperature water more efficiently, making it ideal for rapid rehydration.

  • Metabolic Effect: Drinking cold water causes the body to expend a small amount of energy to warm it, resulting in a minor metabolic boost.

  • Personal Preference Matters Most: The most important factor is drinking enough water consistently, so choose the temperature that encourages you to hydrate regularly.

  • Nightly Dehydration: Since the body becomes mildly dehydrated overnight, rehydrating upon waking is highly beneficial for overall function.

Why Morning Hydration is Crucial

After hours of sleep with no fluid intake, your body is in a state of mild dehydration. Drinking water upon waking is one of the simplest and most effective habits for jump-starting your system. This early hydration helps flush out toxins, aids organ function, and supports better cognitive performance throughout the day. The question is, does the water temperature make a difference?

The Case for Room Temperature Water

Room temperature water, often considered the gentler option, has several benefits for your morning routine. The body absorbs it more quickly without needing to expend extra energy to heat it or cool it down. This makes for more efficient rehydration. Its mild temperature is also less of a shock to your digestive system, which can help kick-start digestion more smoothly. Many people with sensitive teeth or throat issues also find room temperature water more comfortable to drink.

Benefits for digestion and comfort

  • Smooth Digestion: Warm or room temperature water can help stimulate the digestive tract and ease bowel movements, which is particularly beneficial for those prone to constipation.
  • Less Shock to the System: The moderate temperature doesn't cause blood vessels in the stomach to constrict, allowing for more natural absorption.
  • Improved Circulation: Some evidence suggests warmer water can temporarily expand blood vessels, improving blood flow.

The Case for Cold Water

For many, a glass of cold water in the morning is a refreshing jolt that helps them feel more alert. This invigorating effect can be a great way to wake up and start the day. Cold water consumption also has a minor metabolic effect, as the body expends a small amount of energy to warm the water to body temperature.

Benefits for energy and metabolism

  • Increased Alertness: The sensation of cold water can provide a quick mental boost and increase alertness, similar to the effect of caffeine but without the side effects.
  • Minor Metabolic Boost: While minimal (around 8 calories per glass), your body burns energy to warm the water, contributing to a slight increase in metabolism.
  • Workout Performance: If you plan to exercise first thing, drinking cold water can help lower your core body temperature, improving endurance.

Comparison Table: Cold vs. Room Temperature Water

Feature Cold Water Room Temperature Water
Hydration Speed Absorbs more slowly as the body adjusts the temperature. Absorbs more quickly and efficiently, optimizing rehydration.
Metabolism Provides a very slight temporary boost as the body works to warm the water. Has a minimal to no impact on metabolic rate in most individuals, focusing on steady hydration.
Digestion Can cause blood vessels to constrict, potentially slowing down the digestive process for some people. Is gentle on the digestive system, promoting smoother and more efficient digestion.
Energy Boost Offers a refreshing, invigorating sensation that can boost alertness. Does not offer the same sharp jolt, providing a more gradual, natural energy lift from simple hydration.
Comfort Can cause discomfort for those with sensitive teeth or sinus issues. Is gentler on sensitive teeth and throats, and is often more soothing.

Making the Best Choice for You

Ultimately, the choice comes down to personal preference and health needs. There is no single answer to the question, "Is it better to drink cold water or room temperature water when you wake up?". For most people, the most important thing is simply to hydrate consistently, regardless of the temperature. The best option is the one that you will drink regularly and that makes you feel your best.

Putting it into practice

  • Listen to your body. If cold water feels like a great way to wake up, go for it. If it causes discomfort, opt for room temperature.
  • Set a reminder. Keep a glass or bottle of water by your bedside to ensure you don't forget to hydrate first thing.
  • Consider your goals. For a quick energy boost, cold water might be your choice. For gentle digestion, room temperature is often better.
  • Infuse your water. If plain water isn't appealing, consider infusing it with lemon, mint, or cucumber to make morning hydration more enjoyable.
  • Don't overthink it. The cumulative effect of staying well-hydrated throughout the day is far more impactful than the temperature of your first glass.

Conclusion

Deciding if it's better to drink cold water or room temperature water when you wake up depends on what you want to achieve. Cold water offers a refreshing jolt and a minor metabolic kick, while room temperature water provides smoother digestion and quicker absorption. Both are excellent ways to rehydrate after a night's sleep. The critical takeaway is to prioritize morning hydration, as it significantly impacts your metabolism, digestion, and cognitive function. Choose the temperature that aligns with your personal preferences and health goals to make morning hydration a simple and effective part of your daily routine. Consistent hydration, regardless of temperature, is the key to overall health and wellness.

Frequently Asked Questions

No, drinking cold water upon waking is not bad for most people. While it might cause discomfort for those with sensitive teeth or throats, it's a safe and effective way to rehydrate and can provide a refreshing energy boost.

Yes, but only slightly. The body expends a small number of calories to warm cold water to your internal temperature. The effect is minimal, with studies suggesting it amounts to only a few extra calories burned per glass.

For digestion, room temperature or slightly warm water is generally considered better. Cold water can cause blood vessels to constrict and may slow down the digestive process for some individuals.

Yes, drinking water in the morning can assist with weight loss. It can boost metabolism, help you feel fuller before meals, and is often mistaken for hunger. Staying hydrated can curb unnecessary snacking.

Experts often recommend starting with 1-2 glasses (around 250-500 ml) of water in the morning. This amount is enough to kickstart hydration without overwhelming your system. It's best to sip it slowly.

Yes, research suggests that room temperature water is absorbed by the body most quickly and efficiently. Both very cold and very hot water are absorbed slower than room temperature water.

If you have sensitive teeth, room temperature water is a better choice. Drinking cold water can cause discomfort or pain for individuals with dental sensitivity.
