Why is My Hamster Sleeping so Much

If you’re a hamster owner, you might have noticed that your little furry friend seems to sleep a lot. While hamsters are known to be active creatures, it’s not uncommon for them to spend a significant amount of time sleeping.

So, why is your hamster sleeping so much? The most straightforward answer is that hamsters need a lot of sleep to maintain their health and well-being. However, if you’ve noticed a sudden increase in your hamster’s sleeping habits, it could be due to various reasons such as illness, aging, environmental factors, or diet. 

In this blog post, we will delve into the possible causes of excessive sleeping in hamsters and provide guidance on how to prevent and address these issues.

Possible Reasons for Excessive Sleeping

While it’s normal for hamsters to sleep for long periods, there are certain circumstances where excessive sleeping could indicate an underlying issue, including

Possible Reasons for Excessive Sleeping

Illnesses or Injuries

Just like any other animal, hamsters can become ill or get injured. When this happens, their bodies will try to heal themselves, which can result in excessive sleeping. Some common illnesses that can affect hamsters include respiratory infections, mites, and tumors. 

Look out for symptoms, including lethargy, appetite loss, and difficulty breathing. If you suspect your hamster is ill or injured, take them to a veterinarian for a proper diagnosis and treatment.


As hamsters age, their sleep patterns can change. Older hamsters tend to sleep more and become less active, which is normal. If you have an aging hamster, ensure a comfortable and safe environment.

You can ensure a soft and cozy bed, easy access to food and water, and a temperature that’s not too hot or too cold for them. Similarly, you can also give them some gentle exercises, like slow walks or wheel runs, to keep them active and healthy.

Environmental Factors

The environment in which your hamster lives can also affect its sleep patterns. Hamsters are crepuscular animals, which means they are most active during dusk and dawn. During the day and night, they tend to sleep for more extended periods. 

Possible Reasons for Excessive Sleeping

Ensure your hamster’s environment is quiet, with little to no noise or activity levels. Also, to help regulate their sleep patterns, provide a consistent light and dark cycle. Keep the temperature and humidity levels comfortable and ensure adequate ventilation.


A hamster’s diet can also affect its sleep patterns. Nutritional deficiencies can lead to lethargy and excessive sleeping. Ensure your hamster gets a balanced diet that includes fresh vegetables, fruits, and high-quality commercial food.

Overfeeding or underfeeding can also affect their sleep patterns. So ensure that you feed them the appropriate amount for their size and age.
