Hamsters are indeed classic nocturnal animals, and their behavioral habits are closely tied to their circadian rhythms. Here’s a detailed breakdown of their characteristics:
I. Nocturnal Traits
Active Periods
Hamsters are typically active from 7:00 PM to 4:00 AM, curling up in their nests to sleep during the day.
Their peak activity occurs from midnight to early morning, when behaviors like running on wheels and climbing are most frequent.
Evolutionary Reasons
Their wild ancestors evolved to be active at night and rest during the day to avoid the scorching desert heat and predators.
Domesticated hamsters still retain this genetic instinct, and their biological clocks are difficult to adjust artificially.
II. Impact on Humans
Schedule Conflicts
Nocturnal noises—such as running on wheels or gnawing at cage bars—may disrupt their owners’ sleep.
During daytime interactions, hamsters are often drowsy, making the experience less engaging.
Health Risks
Forcibly altering their circadian rhythm can cause stress or shorten their lifespan.
III. Care Recommendations
Provide toys like running wheels and tunnels at night to help them burn off energy.
Avoid disturbing them during the day, and keep their environment dim to mimic their natural sleep-wake cycle.
