Exercise has for long been recommended as cognitive-behavioural therapy for patients with #depression, yet new evidence suggests that the #COVID19Pandemic changed the nature of the relationship between physical activity and mental health.
The study of college students, conducted before and during the #pandemic, revealed the average steps of subjects declined from 10,000 to 4,600 steps per day and rates of #depression increased from 32 per cent to 61 per cent.
The research, published in the Proceedings of the National Academy of Sciences, also revealed short-term restoration of exercise does not meaningfully improve mental well-being.
"This raises many possible explanations, including that the impact of physical activity may require a longer-term intervention," said co-author Sally Sadoff from the University of California, San Diego.
"At the same time, our results clearly show that those who maintained physical exercise throughout the #pandemic were the most resilient and least likely to suffer from #depression," Sadoff added.
For the study, the team used a longitudinal dataset linking biometric & survey data from several cohorts of nearly 700 young adults before and during the #COVID19Pandemic. In addition to filling surveys, participants received wearable devices that track their activity levels.
Among the subjects, sleep increased by 25 to 30 minutes per night, time spent socializing declined by more than half (less than 30 minutes per day), and screen time more than doubled to five or more hours per day.
The researchers found large declines in physical activity during #COVID19 was most strongly associated with higher rates of #depression.
Those who experienced declines of one to two hours of physical activity per day were most at risk for depression during the #pandemic. While participants who were able to maintain their daily habits were at the lowest risk for #depression, the team said.

Human activities have contributed to the massive destruction of nearly two-thirds of the world’s original #TropicalRainforests in the last two decades, a new study has found.
The analysis has revealed logging and land conversion for various agricultural practices as the two primary factors behind the wipeout of these forests, which serve as the largest reservoirs of carbon and effectively mitigate #GlobalWarming.
Over the past few decades, these dietary guidelines have evolved in line with the emerging scientific evidence with an aim to make people healthier while not compromising nature’s ability to sustain future generations.
@iiscbangalore@MrigDixit Dr Rohini M Godbole, a renowned particle physicist from the Indian Institute of Science, Bengaluru (@iiscbangalore), has proved her mettle in the field of science not just in India but across the globe.
@iiscbangalore@MrigDixit Dr Rohini, who hails from Pune, Maharashtra, started her scientific career way back in 1969 when even a journey from Pune to Delhi was a challenge for a girl.
#WorldPolarBearDay: Here are some of the most interesting facts about polar bears, which make them one-of-a-kind in the diverse animal kingdom.
The big, burly white polar bears of the Arctic are among the most loved animals on the planet. However, in recent decades these magnificent animals, which are vital for the health of the Arctic environment, are facing several threats, including the omnipresent climate change.
In the form of retreating ice, we are snatching away their home inch-by-inch year-on-year. In fact, in 2020, a study has projected that polar bears could be gone by 2100 if emissions remain unchecked.
Day by day, new research paints a grimmer picture of the state of our fragile ecosystem from deep-sea corals to the animals on land.
The startling number comes from the latest assessment conducted and compiled by 16 global conservation organizations in a report titled ‘The World’s Forgotten Fishes’.
@MrigDixit Before us—the modern human beings or Homo sapiens—tens of thousands of years ago, the planet was dominated by an ancient sibling of ours called #Neanderthals or Homo neanderthalensis.
@MrigDixit While their existence dates back to at least 200,000 years ago, Neanderthals went extinct roughly 40,000 years ago. Several theories have emerged in recent years explaining the cause of their extinction—from #climatechange to a deadly disease.
