How Long Do Dragons Live?


If someone asks about the most popular reptile as a pet, the answer without any doubt will be Bearded Dragon. For anyone who wants to have a lizard as a pet, a Bearded dragon is the best option for him. Bearded dragons are easy to handle and get very touchy with their owners. Unlike other lizards that are active at night, bearded dragons stay awake the whole day, climb branches and sit on the logs to bask themselves in the sunlight.

Bearded dragons have distinguishing traits and characteristics that make them the best pets. These dragons have pouch-like skin folding under their necks covered with spiny projections, giving a similar look to a man’s beard. That is why they are named “Bearded Dragons.”

There is one of the main reasons behind Bearded prominent being the most favorite reptile pet and is their long life span. The average life span of the bearded dragon is 8 to 15 years in captivity. This range can vary depending upon how the owner is taking care of them, and also a variety of genetic factors is also involved in determining their life span.

What Factors Affect The Lifespan Of Bearded Dragons?

How long bearded dragons live depends upon many factors, including their diet, how they are cared for, where they live, gender, genetics, their diet, medical care, and environmental factors. 

It would be the best if you always remember that there is no guarantee to the lifespan of bearded dragons (or any other pet). Your pet can fall victim to a nasty luck illness even after cared for very well by you.

If speaking statistically, you can improve the lifespan of your bearded dragon by doing the right things.


The quality of food you feed to your pet can help them stay healthy and combat diseases, thus increase their lifespan. If you want your bearded dragon to live a long life, a well-balanced and nutritious diet will help you. As bearded dragons are omnivores means they need both plant-based and animal-based diets. 

The diet of dragons varies according to their age. As young dragons need a high protein diet; thus, they should be given 80% insects and 20% greens and vegetables. They reach their maturity when they turn ten months old. When your dragon is done growing, you will give them less protein in their diet, so 80% of greens and vegetables and 20% of insects should be fed.

Insects to feed them include moths, crickets, dubia roaches, slugs, cockroaches, earthworms, silkworms, grasshoppers, and spiders.

It isn’t easy to make your bearded dragon feed vegetables. Still, it would be the best if you try giving them various plant-based foods, including kale, mustard greens, collard greens, broccoli, parsnips, parsley, cucumbers, mushrooms, green beans, zucchini, asparagus, pumpkin, corn, peas, and celery.

Your pet will love to eat fruits, but fruits should not be over 10% of their diet, no matter how old they are. Fruits you can give include peaches, apricots, mangoes, apples, grapes, tomatoes, watermelon, and pineapples. 

Enclosure And Habitat

To stay healthy, your bearded dragon needs a proper habitat setup. The setup you provide them should mimic their natural environment. Properly maintained temperature, lighting, and humidity level is needed for their increased lifespan. 

Their enclosure’s size matters a lot. For baby dragons 80 liters tank, a 160 liters tank for juvenile dragon (10-16 inches long), a 200-300 liters tank for an adult (16-20 inches long), and a 300-500 liters tank for adult bearded dragons (more than 20 inches long).

The substrate you use for your pet makes a difference in their health. Particle and non-particle substrates can be used for your lizard’s enclosure. But you should be careful as particle substrate will produce dust and debris that, if your lizard ingests, will lead them to impaction. Impaction will cause serious health issues and may cause death if it’s not taken care of. If the particle substrate gets into the nose and eyes of your pet will lead to infection.

So, non-particle substrates like reptile carpet, newspaper, ceramic tile, and non-adhesive linoleum are considered safe for bearded dragons. 

That will be the best if you put a hide in their tank, as they love crawling into them to sleep, and it will help them during brumation.

Humidity And Temperature Conditions

If you want a lengthy lifespan for your lizard, you must keep their enclosure at the right temperature. Both, a more relaxing spot and a basking spot are essential. Temperature also varies according to their age and also on what time of day it is.

For babies basking temperature should be 100-110oF, for juveniles and adults 96-100oF, for cooler spot temperature should be 80-90oF and 75-80oF for juvenile and adult bearded dragons. At night temperature of their tank should be 70-75oF for all ages. 

With basking light, UVA/UVB light source is also essential to be in their tank. Light will help your lizard to digest their food. Your pet will become if the light source is not provided to them. 

A humidity level below 40 degrees is needed. Failing to give this humidity level can cause respiratory problems in them, so you can measure their tank’s humidity level using a hygrometer. 


Male bearded dragons live longer than female ones. Here are some reasons why males tend to live longer. The first reason is that male bearded dragons are longer than females, and size impacts their lifespan length.

And another reason is breeding. As female bearded dragons expand their energy while breeding, that brings a difference in their life expectancy.


In general, the more extensive the bearded dragon in size, long they have a lifespan. So you should make sure to provide a well-balanced and nutritious diet to them to grow them as large as they can. You should also provide an enclosure with enough space for them to grow. Larger bearded dragons seem to be more resilient than the shorter ones.
