We are providing this as a source for current and relevant psychological research and will only share research from reliable sources. However, be a good consumer of research! We encourage you to think about findings as tentative when they are from new research or a single study. Until there is replication of findings and ultimately an analysis that combines many different studies, consider the findings from individual studies to be possibilities rather than certainties.

Exercising Outside May Make Exercise More Pleasant.
"Fresh Air" Lengthy bouts of exercise feel easier and more pleasant when done outside, suggests a study in PLOS One. Each of 42 healthy participants engaged in three types of activities on different days: a three-hour mountain hike, a three-hour session on an indoor treadmill, and three hours relaxing in a room with computers and magazines. Participants took part in all activities in groups of between three and eight members, and the order of the activities was varied across participants. They wore heart monitors during the activities and answered survey questions about their moods and anxiety levels at the beginning and end of each session. The researchers found that although the mountain hike was more strenuous than the treadmill walk—participants' heart rates rose higher on the hike—the participants reported that the treadmill walk felt more strenuous. Also, participants reported better moods after the hike than after the treadmill session, and better moods after either bout of exercise than after relaxing with computers and magazines.
"Bright daylight, better sleep" Spending time in bright light during the day could mitigate the sleep disturbances caused by blue-light exposure from device screens at night, suggests research published in Sleep Medicine. In a sleep lab, 14 participants were exposed to very bright light—similar to daytime light—for 6.5 hours. Then, half were instructed to read a hard-copy novel and half an e-reader novel for two hours before bed. The researchers then monitored participants' sleep overnight and found no differences—in melatonin levels, sleep duration or sleepiness—between the hard-copy and e-reader participants. They say this suggests that bright daytime light exposure could help mitigate the effects of nighttime blue-screen exposure, though caution that larger studies are needed.
