Summer, winter and fall may have their fans, but spring is clearly the most lovable of the four seasons. Here are some scientific reasons why spring is great.
Spring marks the end of a cold winter. In many places, the temperature in this season is about 15 to 21°C. People tend to be the most comfortable at temperatures around 22°C, so the arrival of spring means people can finally get off their heavy winter clothes and still be comfortable.
Warmer temperatures make people want to spend more time outdoors without freezing their feet, which is great for mental (心理) health. Across the seasons, research has found that taking walks in nature slows people’s heart rate and makes them more relaxed. Spending 30 minutes or more outside in warm, sunny spring weather will put people in a cheerful mood. People can also have better memories through a walk.
Following the spring equinox (春分), days begin lasting longer and nights get shorter. That means people have more light hours to get things done. Research has shown that those extra hours of sun can be an important mood-booster. The longer the sun is up during the day, the less blue people feel.
In addition, many animals move south during the winter. Then they move back north as temperatures rise. For northern areas, there’s no better sign of spring than birdsong outside the window. Birds can start flying north as early as mid-February and it lasts into June. It means that throughout the spring, people can expect to see lots of birds. And seeing more birds can make people happier. A UK study has found that the more birds people see in their neighborhoods, the better their mental health is.
