Movement

Regular activity gives a small, reliable lift in good moods, and a single walk helps within minutes. For training plans, go to liftgood.now.

• Evidence: Strong
• Takes: 10 minutes or more, most days

Why it matters

Movement works on two time scales.

Right away. A meta-analysis of 103 studies with over 4,600 people measured mood before and within 30 minutes after one bout of exercise. Mood improved, and anxiety went down [2]. The size of the lift varied a lot between studies, and no one has yet worked out exactly why.

Over weeks and months. A meta-analysis of studies in healthy people found a small positive link between physical activity and wellbeing. It showed up in experiments, not just surveys, and it didn’t depend on how fit people were to begin with [1]. The effect was mainly more good moods, not fewer bad ones.

You don’t need to do a lot. In four experiments, walks of only 10 to 15 minutes left people feeling more energetic and more pleasant, in the lab and outdoors [3]. In a survey of 1.2 million Americans, people who exercised reported fewer days of poor mental health in the past month than similar people who didn’t. The best results went with sessions of about 45 minutes, three to five times a week, and more wasn’t always better [4]. That’s a survey, so it can’t prove the exercise caused the difference.

How to do it

1. Start with walking. It needs no kit and no plan. A brisk 10 to 15 minutes is enough to notice a change in mood [3].
2. Tie it to something you already do. Walk after lunch, get off the bus a stop early, take calls on foot.
3. Pick activities you like. You’ll keep doing things you enjoy. Team sports, cycling and gym sessions all did well in the large survey [4], but the best one is the one you’ll repeat.
4. Build up to most days. Over time, aim for a mix of moving most days and something harder a few times a week. liftgood.now has plans for strength and fitness.
5. Go outside when you can. A walk outdoors also counts towards daylight and time outdoors.

Common mistakes

• All or nothing. Skipping a walk because you can’t do a full workout throws away the easiest win.
• Starting too hard. If every session feels awful, you’ll stop. Moderate effort you can talk through is fine.
• More is always better. In the large survey, very long or very frequent sessions didn’t go with better mental health than moderate amounts [4].
• Waiting until you feel like it. Mood usually improves after you start moving, not before.

Evidence

Rated Strong. Two large meta-analyses agree that activity improves mood, both straight after a session [2] and over time [1]. The effects are small to moderate and vary a lot from study to study. The 1.2 million-person survey adds useful detail on amounts, but it shows a link, not cause and effect [4].
