National Pet Day is April 11, although if you’re a pet owner, you know there’s not a day that goes by that you don’t celebrate your animal companion! So hug your hedgehog, bond with your bunny, and cut your kitty some catnip! That critter makes you happy — and that’s not all. Over the past 10 years, the National Institutes of Health (NIH) has been a partner in research to determine the physical and mental benefits of having a pet. It turns out that not only can pets steal our hearts, but they also contribute to overall cardiovascular health by lowering cortisol, cholesterol, and blood pressure levels.

Earth Month takes place during April every year. It’s a time to raise environmental awareness and create consciousness around the issues that affect mother nature during this time of crisis. Every April, leaders, and environmental activists from all over the world join hands to create sustainable development and offer climate solutions, to minimize our carbon footprint and prevent further harm to our planet’s natural resources. It’s increasingly important to observe this month as Earth starts to unravel the harmful effects of climate change which not only poses a threat to our existence but is irreversibly damaging all forms of life.
