The presence of a pet can make us feel happier and calmer, especially when we’re stressed out. The reason behind this phenomenon is that pets provide unconditional love, which makes people feel loved and cared for. This feeling of security helps them relax and fall asleep faster.
A study conducted at the University of California San Diego showed that dogs help their owners get to sleep faster. In addition, they found that having a pet around reduces stress levels and improves overall moods.
In another study, researchers from the University of Pennsylvania discovered that dogs can even improve our health. They found that sleeping next to a dog can reduce blood pressure and heart rate, while increasing oxygen saturation.
