The same ideas, all in one place, with links to the research behind them.
Sunlight
Morning light sets your body clock
Light is the strongest signal your internal clock gets. Getting bright light early in the day helps set the rhythm that decides when you feel alert and when you feel sleepy, and light exposure is closely tied to sleep and mood.
Try this: Step outside within an hour or so of waking, even for 10 minutes. Cloudy days count. Never look directly at the sun.

Nature
Two hours a week outside
In a study of nearly 20,000 people in England, those who spent at least 120 minutes a week in nature were more likely to report good health and wellbeing. It didn't matter whether it came in one long visit or a few short ones.
Try this: A 20-minute walk somewhere green, a few times a week. A park, the beach, or a tree-lined street all count.
Research: White et al. (2019), Spending at least 120 minutes a week in nature is associated with good health and wellbeing, Scientific Reports
Movement
Movement lifts mood
A 2024 review of 218 trials found that exercise, including walking, jogging, yoga and strength training, reduced symptoms of depression. More vigorous movement tended to help more, but every kind helped some.
Try this: Dance in your kitchen to one song. Take the long way to the mailbox. Small counts.
Research: Noetel et al. (2024), Effect of exercise for depression, BMJ
Gut and brain
Your gut and brain are always talking
Your gut and brain send messages back and forth through nerves, hormones and the immune system, and the trillions of microbes in your gut are part of that conversation. Scientists are actively studying how this connects to stress and mood. A lot of the research is still early, and much of it comes from animal studies.
Try this: Get curious. Notice how different foods leave you feeling a few hours later, without judging yourself.
Research: Cryan et al. (2019), The Microbiota-Gut-Brain Axis, Physiological Reviews
Food and mood
What we eat can shape how we feel
In the SMILES trial, adults with depression who had support to eat a Mediterranean-style diet for 12 weeks improved more than those who got social support alone. The study was small (67 people), so it's promising, not the final word.
Try this: Add one colorful plant to a meal today. And yes, there's still room for tiramisu.

Connection
We're wired for each other
A review of 148 studies with more than 300,000 people found that people with stronger social relationships were about 50% more likely to survive over the study periods. Connection isn't a luxury. It's part of how we stay well.
Try this: Send one text to someone you miss. It doesn't need to be long.
Research: Holt-Lunstad, Smith and Layton (2010), Social relationships and mortality risk, PLOS Medicine
Breath
Slow breathing calms the body
Breathing slowly, around six breaths a minute, is linked in many studies with feeling more relaxed, steadier heart rhythms and less anxiety. It's one of the fastest ways to tell your nervous system it's safe.
Try this: Breathe in for 4 and out for 6, five times. Or try the moon on the 2am Reset page. Breathe with the moon.
