Reading is regarded as a passive, quiet process, but the question that many people ask themselves is: does reading burn calories? You may be surprised at the answer. Although reading will not substitute a gym session, your brain is still working overtime. That is, you are consuming energy- even when you are sitting still reading a book.
In this article, we’ll break down how reading affects calorie burn, how many calories you actually use, and whether reading can support your health goals.
What Happens to Your Body When You Read
You might be reading and your body might appear to be very relaxed but your brain is very active. Reading is a multitask process that is carried out simultaneously- decoding words, meaning, visualizing ideas and retaining information in the memory.
All this activity needs energy. Even when you are at rest, your brain burns glucose (a form of sugar). Actually, the brain is one of the most energy consuming organs in the body and it consumes approximately 20 percent of your daily energy intake.
Thus, although reading does not get your muscles moving, it does burn calories in your mind, so your body is still working, albeit in an imperceptible but actual sense. Small increments in energy usage are related to eye movement, attention focus, and comprehension.
How Many Calories Does Reading Burn?
Next the big question, how many calories does reading burn?
Most adults burn an average of 30 to 50 calories per hour reading. This figure may change a little with your body weight, reading speed and concentration.
In perspective, this is comparable to other sitting activities that require low effort such as writing or typing. While it’s not a high-calorie-burning activity, it still contributes to your overall daily energy expenditure.
For example:
- 1 hour of reading = ~40 calories
- 1 hour TV viewing = approx. 35-45 calories.
- 1 hour of light desk work = -50 calories.
As you may notice, reading is in the same category as other sedentary activities. Yes, reading does burn calories, but very few.
Factors That Affect Calories Burned While Reading
Not all reading experiences burn the same number of calories. The amount of energy that your body consumes can be affected by several factors.
First, the level of concentration is significant. In-depth, intensive reading, like reading and analyzing difficult material, involves more brain activity than reading a magazine or comic book.
Second, the posture of the body is important. Sitting up, holding a book or even sometimes moving your eyes and hands a little can use a little more energy than lying down.
Third, the reading environment can also have an impact. Silence enhances concentration, which can boost mental activity and expenditure of energy. Conversely, distractions may decrease mental effort.
Lastly, personal factors like age, weight and metabolism also influence calorie burn. The bigger body or the more active metabolism can consume a little more energy even when performing passive tasks such as reading.
Reading vs Other Low-Intensity Activities
Comparing reading with other activities that one does in everyday life, it is evident that reading is not the lowest in terms of calorie burning, though it is not the lowest.
For instance, activities like sleeping burn about 40–60 calories per hour, which is similar to reading. Light cleaning, slow walking around the house, or cooking typically burn more calories than reading.
Nevertheless, reading is one of the activities that has a distinct benefit: it engages the brain more than other activities that do not involve physical activity, such as watching TV or scrolling through a phone. The difference in calories is not much, but the psychological gains are huge.
So, while reading may not help you burn fat quickly, it keeps your brain active and engaged without putting stress on your body. It’s a healthy alternative to more passive screen time.
Can Reading Help With Weight Loss Goals?
Reading will not result in much weight loss but it can help in maintaining a healthy lifestyle indirectly.
To begin with, reading may substitute such bad habits as snacking in front of the TV or scrolling your phone without thinking. By replacing 1-2 hours of screen time with reading, you can potentially decrease the number of calories you consume due to unneeded eating.
Second, stress can be alleviated through reading. Reduced stress levels are associated with the improvement of eating habits and decreased emotional eating, which can help in weight management.
Third, pre-sleep reading can enhance the quality of sleep. Healthier metabolism and appetite control are related to better sleep.
Therefore, the amount of calories burned during reading is insignificant, but the lifestyle gains can be added to long-term wellness and improved weight management habits.
How to Make Reading a Healthy Habit
When you like reading, you can make it a more balanced aspect of your day. Although it will not substitute exercise, it can be used in addition to a healthy lifestyle.
Attempt to devote at least 20-60 minutes a day to reading. This will aid in minimizing screen time and will provide your brain with a healthy break in the digital overload.
Light movement can be combined with reading too. As an illustration, you can have short standing breaks after every 30 minutes or stretch as you consider what you have read. This keeps your body a little bit more active.
It is also important to select interesting books. The more you are interested in the content, the more mentally active you are, which can slightly raise the amount of cognitive energy used.
Above all, reading should be viewed as a good mental health practice, rather than a calorie-burning one. It enhances concentration, develops vocabulary, and maintains your brain.
