Carol Heffernan, a 43-year-old woman from Oshkosh, Wisconsin, regularly felt worn out from working, driving her two kids to school, and taking care of housework. But when COVID-19 hit in March, 2020 and the kids were suddenly home all day and learning remotely, her usual weariness quickly turned into full-on exhaustion. "All the extra responsibility and the mental load—it just added up," she says. "I felt tired, and it wasn't due to lack of sleep."

If there's one thing many of us have in common, it's that we're tired. Doctors even have a name for it: "tired all the time," or TATT for short. The solution isn't always as simple as getting more sleep; nearly a quarter of people who get seven or more hours of rest a night report that they still wake up feeling tired most days.

A few weeks after feeling tired, Heffernan decided to drop everything and go for a walk, which she hadn't done since the pandemic(大流行病)began. "I just wanted to be by myself," she says. "I needed a break." When she returned, she felt recharged and decided to make a habit of it.

Doing something active when you're feeling sluggish(懒洋洋的)will actually increase your energy, but it will not consume the little that you have. In fact, researchers at the University of Georgia found that just ten minutes of low or moderate intensity exercise gave study participants a noticeable energy boost.

In another recent study, people who committed to working out for 20 minutes three times a week increased their energy levels by 20 percent in six weeks." When we don't work out regularly, our muscles can become weakened, so when we do use them in everyday activities, we're more tired," explains Dr Yufang Lin, a physician at the Cleveland Clinic's Center.

Now, Heffernan goes for a daily 45-minute stroll. "It feeds me spiritually, emotionally, and physically," she says. "I have something to look forward to every afternoon. I'm in a better mood. And after putting the kids to bed, I have the energy to stay up and talk to my husband."
