Without proper warmth for more than 72 hours, the Iguana’s vital bodily processes are likely to be disrupted. Because of too much frigidity, an iguana could not be able to move or eat, causing death very quickly. These processes can last between 72 hours and one month, based on your age and the general conditions in the enclosure.

If there’s no vegetation, Iguana may die because of extreme cold that lasts for too long. This is why it’s vital to have plants and the necessary equipment to embellish their enclosures for their daily needs. If you place your enclosure at a higher altitude, that is where the wind can strike gusts with precipitation; it could level off within two days.

Please don’t allow your Iguana in your house for too long without a sustainable heating source for them. Iguana typically depends on heat sources outside for their body functions and to stay active.

3 Reasons Why Do Iguanas Need Heat?

Warmth is a must for lizsrds such as iguanas since they’re cold-blooded; below are a few reasons why iguanas require external sources of heat to maintain their health and remain active.

In addition to aiding in their bodily functions, it also helps regulate the body’s temperature, and it can also help with digestion. This article will discuss the various aspects in detail to discover how we can improve each one and ensure that your iguanas are at ease.

Temperature Gradient & Basking

It is vital to have heat source for maintaining their basking place temperature. The enclosure must have a comfortable temperature and air for their comfort and well-being. The place where Iguana bask in is between 85 and 90 degrees Fahrenheit. It is vital to put in a thermometer that can monitor the temperature of your iguana’s enclosure to ensure that they’re healthy.

For Proper Calcium Absorption

If the heating is not adequate or there is no source if proper heating, an Iguana could have a difficult time when it comes to absorbing calcium. In the absence of calcium, they may be afflicted by metal Bond diseases.

If the Iguana isn’t absorbing sufficient calcium in its diet, it is not receiving the calcium they require through its daily diet. The proper absorption of calcium by Iguana is partly dependent on temperature. Suppose there isn’t enough hearing in the enclosure.

In that case, Iguanas will not only have issues digesting food but also will not be able to allow proper calcium absorption and have a higher chance of developing heart diseases because of constant cold temperatures. The signs of calcium deficiency in Iguana are usually characterized by swelling joints, slugs and them.

Metallic Bond disorders and bone deformities may occur because of the absence of heat.

For Proper Digestion

The warmth is required to stimulate good bacteria within your Iguana stomach. These beneficial bacteria aid in digestion. The iguanas need heat digestion to help digest foods. Are you aware that you should leave your Iguana in its favourite spot to bask after eating? Is it a great way to stop constipation and digestion issues? It’s common to see Iguana sitting on a rough heat pad after eating lunch or dinner to warm their stomachs.

Many digestive problems such as constipation and bloating can be experienced without heating. It is essential to monitor the temperature in an iguana’s enclosure throughout the day, especially in the winter months, to help it to be able to take in food properly and maintain regular, healthy bowel movements.

If an iguana suffers from Indigestion, it will experience a decrease in appetite, sedentary behaviour, slowness, inactivity eating, and regurgitation of food. They may also be circuling around the source of heat. These are symptoms of Indigestion in iguanas, which indicates that there isn’t enough heat to sustain normal bodily function.

To Regulate Body Temperature

Being reptiles with cold blood, Iguanas cannot regulate and warm their body temperature by themselves. They require warm places within their enclosures to avoid getting sick or too rigid. Without a good basking place that regulates the body temperature of your Iguana will eventually cease.

Regulating a guana’s body temperature lets them lead an active, healthy, and comfortable life. With the proper temperature, they’ll have fewer food needs. If you find your Iguan having issues regulating their body temperature on their own, the heating pad must be replaced.

Always ensure that ceramic pads are in place and the heaters are set for nighttime heating. Check that the heat lamps can supply warmth as you would expect. The winter months are the most sensitive season for your pet iguanas. If they are not heated during the cold winter days, the body’s temperature will rise significantly, making them feel tired or even dying.

It is recommended to install heating pads inside the enclosure and rocks to hold the heat for a more extended amount of time. They are inexpensive and highly efficient in providing warmth to Iguanas. Suppose you want to avoid problems with body temperature regulation because of the absence of adequate heating in Iguanas. In that case, you should check the heating devices and determine whether they’re operating as expected. Always ensure that you have a backup power source in case of power outages frequently occur in your local area.

Iguanas always need more helpers to regulate heat rather than a thermostat. It is crucial to ensure that your pet receives adequate warmth in the area he’s in his place. They must have a place to take a bath whenever they want while also ensuring that their diet is sufficient in dietary calcium. Here are some commonly asked questions regarding Iguanas and the need for warmth.



So an Iguana can survive up to one month without a heating source. But, the body’s temperature should be at a healthy level. Otherwise, health problems or death may be a possibility. I have tried to give you the complete details on how long Iguanas live without heat.
