At a time when we are experiencing an extraordinary level of stress, science offers a simple and effective way to A bolster our emotional health. To help yourself, start by helping others.

Much of the scientific research on resilience -- our ability to bounce back from adversity -- has shown that having a sense of purpose, and giving support to others, has a significant impact on our well-being.

'There is a lot of evidence that one of the best anti-anxiety medications available is generosity,' said Adam Grant, an organisational psychologist at The Wharton School of the University of Pennsylvania, US. 'The great thing about showing up for other people is that it doesn't have to cost a whole lot and it ends up being beneficial to the giver. Studies show that volunteering, donating money, or even just thinking about donating money can release feel-good brain chemicals and activate the part of the brain stimulated by the pleasures of food and sex. Studies show that do-gooders had lower levels of the stress hormone cortisol on days they did volunteer work.

The challenge many of us are facing today is how to give support from a distance. The good news is that the type of support that can be helpful to both giver and receiver can be given in a variety of small and big ways. It can include giving money or time to a cause. Or it can be as simple as a phone call or giving advice.

In fact, the act of giving advice has been shown to be more beneficial than receiving it. Researchers from the University of Pennsylvania and the University of Chicago, US, found that after middle-school students mentored younger students, they ended up spending more time on their homework. Overweight people who counselled others on weight loss were more motivated to lose weight themselves.

We are better at giving advice to others than ourselves. 'One of the best things you can do is call someone else facing a similar problem and talk them through it,' said Grant, who cofounded an online networking platform, Givitas, which connects people for the purpose of asking for and giving support and advice. 'When you talk other people through their problems, you come up with wiser perspectives and solutions for yourself. Feeling responsible for other people also can help us cope with whatever challenges life brings. Emily A. Greenfield, an associate professor of social work at Rutgers University, US, studied a concept called 'felt obligation,' which is measured by asking people questions such as how obligated they would feel to give money to a friend in need. Greenfield analysed data collected from 849 participants in an ongoing study of health and well-being that asked about felt obligation as well as health-related declines they experienced over time, such as problems carrying groceries or walking a block.

As it turned out, the people who had higher levels of felt obligation -- meaning they were the type of people to sacrifice for others -- coped better with their own life challenges.

'These findings fit with the idea that an orientation to helping others is a protective factor -- something that is especially important for well-being when confronted with distressing life circumstances,' Greenfield said.

She noted that caring for others helps us to regulate our own emotions and gain a sense of control. 'When we remind a friend that social distancing measures are temporary, and this too shall pass, we are in effect reminding ourselves and serving to regulate our own emotions,' she said.

Several studies suggest that supporting others helps buffer our bodies against the detrimental effects of stress. A five-year study of 846 people in Detroit, US, found that stressful life events appeared to take a greater toll on people who were less helpful.

'Small acts are important,' said Dr Steven Southwick, professor emeritus of psychiatry at Yale University School of Medicine, US. 'Part of that might have to do with just getting outside of myself, and finding meaning and purpose in something bigger. Studies show that having a strong sense of purpose protects us from stress in the short term and predicts long-term better health, a lower risk of dying prematurely and even better financial health. Researchers say that finding meaning and purpose during social distancing may be especially important for high school seniors and college students.

'Your purpose may be to help others in need, but it doesn't have to be tackling big social structure issues,' said Patrick Hill, associate professor of psychological and brain sciences at Washington University in St. Louis, US. 'It could be helping out your neighbour or just doing shopping for somebody. If your big picture goal is to help others in need, there are ways of doing that right now that may look different than how you used to do them.
