Understanding Calorie Burn: Laying in Bed vs. Being Active
Ever wondered how many calories do you burn laying in bed all day? It’s an interesting question with some surprising answers. Even when you’re doing absolutely nothing, your body is still hard at work burning calories. Here’s the quick answer:
You’ll burn approximately 69 calories per hour if you weigh 180 lbs, just by laying in bed all day.
So, what does this mean in terms of your overall energy expenditure?
Our bodies need energy—or calories—to maintain basic functions like breathing, circulating blood, and cell production. Even at rest, this energy use is called your basal metabolic rate (BMR). BMR accounts for roughly 60-75% of the total calories you burn in a day, depending on factors like age, weight, and muscle mass.
I’m Ben Trapskin, founder of Yawnder. My own poor sleep experiences inspired me to dive into the science of sleep and metabolism. Through my research, I’ve learned just how passive activities like laying in bed still require energy.
Ready to dive deeper? Let’s compare calorie burn laying in bed versus being active.
How Many Calories Do You Burn Laying in Bed All Day?
Factors Influencing Calorie Burn While Laying in Bed
Even when you’re lying in bed all day, your body is still at work. This continuous energy expenditure is mainly driven by your Basal Metabolic Rate (BMR), which is the number of calories your body needs to maintain basic physiological functions like breathing and circulation.
Several factors influence your BMR and, consequently, how many calories you burn while laying in bed:
- Age: Younger people tend to have higher BMRs because their bodies are still growing and developing. As you age, your BMR typically decreases.
- Weight: Heavier individuals generally burn more calories at rest because their bodies require more energy to maintain basic functions.
- Body Composition: Muscle burns more calories than fat. Therefore, people with more muscle mass will have a higher BMR.
- Hormone Levels: Hormones like thyroid hormones can significantly impact your metabolism. Conditions like hypothyroidism can lower your BMR.
- Genetics: Your genetic makeup can influence your metabolic rate and how efficiently your body uses energy.
Calculating Your Calorie Burn
To get a rough estimate of how many calories you burn laying in bed all day, you can use the BMR equation. The most commonly used formula is the Harris-Benedict equation, which takes into account your sex, weight, height, and age.
Here’s how you can calculate it:
For Men:
[ \text{BMR} = 66.5 + (13.8 \times \text{weight in kg}) + (5 \times \text{height in cm}) – (6.8 \times \text{age in years}) ]
For Women:
[ \text{BMR} = 655 + (9.6 \times \text{weight in kg}) + (1.8 \times \text{height in cm}) – (4.7 \times \text{age in years}) ]
For example, if you’re a 30-year-old woman weighing 70 kg and standing 165 cm tall, your BMR would be:
[ 655 + (9.6 \times 70) + (1.8 \times 165) – (4.7 \times 30) = 655 + 672 + 297 – 141 = 1483 \, \text{calories/day} ]
This means you would burn approximately 1483 calories per day just lying in bed.
Daily Activities and Metabolism
While your BMR accounts for a significant portion of your daily calorie burn, other factors like daily activities and overall metabolism also play a role. Even activities like digesting food and maintaining body temperature require energy.
To sum up, understanding your BMR and the factors that influence it can give you a clearer picture of how many calories you burn while laying in bed all day. This knowledge can help you make more informed decisions about your diet and exercise routines.
Now, let’s compare this to the calories burned during various activities.
Comparing Calorie Burn: Laying in Bed vs. Being Active
Calories Burned in Common Activities
While laying in bed all day, your calorie burn is primarily determined by your basal metabolic rate (BMR). However, being active significantly increases your calorie expenditure. Here’s a quick comparison:
-
Sitting: If you weigh 155 pounds, you’ll burn around 42 calories per 30 minutes just sitting and reading. This is still higher than the 23 calories burned sleeping for the same duration.
-
Standing: Standing burns about 86 calories per hour for someone who weighs 180 pounds. This is more than twice the calories burned lying in bed.
-
Walking: A casual 20-minute stroll can burn 61 calories. If you walk for an hour, you’ll burn around 183 calories, equivalent to the calories burned during 8 hours of sleep for a 155-pound person.
-
Jogging: A 30-minute jog at 5 mph can burn 298 calories for a 155-pound individual. That’s over ten times the calories burned lying in bed for the same duration.
-
Housecleaning: Engaging in housecleaning activities can burn around 240 calories per hour. This is a great way to stay active and keep your home tidy.
-
Gardening: Gardening burns about 309 calories per hour. It’s an excellent way to combine physical activity with a productive task.
-
Climbing Stairs: This vigorous activity can burn around 660 calories per hour. Even 15 minutes of climbing stairs can burn 165 calories, making it a powerful calorie-burning activity.
Boosting Your Basal Metabolic Rate
Increasing your BMR can help you burn more calories even while at rest. Here are some effective strategies:
-
Muscle Mass: Increasing your muscle mass can lift your BMR by up to 15%. Muscle tissue burns more calories than fat, even at rest.
-
Strength Training: Incorporating strength training exercises into your routine can help build muscle mass. Activities like lifting weights or using resistance bands are excellent choices.
-
High-Intensity Interval Training (HIIT): HIIT workouts involve short bursts of intense activity followed by rest or low-intensity exercise. This type of training can boost your metabolism and increase calorie burn long after the workout is over.
By understanding how different activities affect your calorie burn and incorporating strategies to boost your BMR, you can make more informed decisions about your fitness routine.
Next, let’s explore how to increase calorie burn while sleeping.
How to Increase Calorie Burn While Sleeping
Tips for Better Sleep and Increased Calorie Burn
Thermic Effect of Food (TEF): Your body uses energy to digest and break down food, known as the thermic effect of food (TEF). Foods rich in protein can boost your metabolism more than carbs or fats. High-protein snacks before bedtime, like Greek yogurt, cottage cheese, or a handful of nuts, can increase your TEF and help you burn more calories while you sleep.
Cool Room Temperature: Setting your thermostat to about 66 degrees Fahrenheit can help you burn 7% more calories during sleep. Cooler environments force your body to work harder to maintain its core temperature, increasing caloric expenditure.
Sleep Hygiene: Good sleep hygiene is crucial. This includes maintaining a consistent sleep schedule, turning off electronic devices before bed to reduce blue light exposure, and creating a dark, quiet sleeping environment. Poor sleep can slow down your metabolism and decrease your energy expenditure.
Exercise Timing: Schedule your workouts at least three hours before bedtime. Exercise boosts your metabolic rate, but doing it too close to bedtime can interfere with your sleep quality. Opt for morning or early evening workouts to maximize both your calorie burn and sleep quality.
Foods That Boost Metabolism
Greek Yogurt: This protein-packed snack not only keeps you full but also helps increase your TEF. It’s an excellent choice for a bedtime snack.
Cottage Cheese: Another high-protein option, cottage cheese can help keep your metabolism active through the night.
Nuts and Seeds: Almonds, walnuts, pistachios, pumpkin seeds, and chia seeds are great sources of protein and healthy fats. They can help sustain your metabolism and provide essential nutrients.
Roasted Chickpeas: These are a crunchy, high-protein snack that can keep your metabolism active while you sleep.
By incorporating these strategies and foods into your routine, you can improve your calorie burn even while you’re asleep.
Frequently Asked Questions about Calorie Burn
How many calories do you burn in 8 hours of sleep?
The exact number of calories burned during sleep varies based on factors like age, weight, and metabolism. On average, people burn between 40 – 80 calories per hour while sleeping. Over an 8-hour period, this translates to burning between 320 – 640 calories.
This range can be influenced by your basal metabolic rate (BMR), which is the minimum number of calories your body needs to perform basic functions like breathing and circulation. People with higher BMRs will burn more calories even at rest.
How many calories do you burn in 30 minutes of sleep?
If you take a short nap or sleep for just 30 minutes, you can expect to burn between 20 – 40 calories. This is significantly lower compared to other light activities. For instance, a 30-minute walk can burn between 100 – 200 calories, making it a more efficient way to increase your daily calorie burn.
Can you burn 2000 calories in your sleep?
Burning 2000 calories in your sleep is highly unlikely. Most people burn between 320 – 640 calories over 8 hours of sleep. To burn 2000 calories, you would need an extremely high basal metabolic rate, which is not typical for most individuals. The highest calorie burn occurs in those with increased muscle mass and metabolic rates, but even then, reaching 2000 calories solely through sleep is not feasible.
