Positive Thinking and Gratitude are concepts that have been handed down to us from community elders, over centuries. They form the backbone of teachings in almost every religion of the world, or any form of spiritual practise. Unfortunately, they have been wrongly relegated to the confines of religion, philosophy and literature. Woke-liberal, pseudo-intellectual, western-educated and atheistic-agnostic groups of people have often dismissed them as abstract concepts that are rooted in emotion and not having any scientific basis.

However, in the last couple of decades, more and more research scientists and doctors are acknowledging the direct health benefits of these concepts or approach to life. Several researchers from leading institutes and universities across the world (especially in the US) have published papers in leading journals, outlining studies that show health benefits of positive and/or thinking gratitude. This includes Glenn Fox, Emmons, McCullough, Martin Seligman, Bartlett, DeSteno, etc. The list is very long, and for want of space, we cannot list all of them here.

While positive thinking encourages looking at the bright side of whatever happens to us, gratitude encourages a thankful feeling for the life we have. They are two different concepts altogether, but for the purpose of this article, they have been combined. For the simple reason that, the physical, mental, emotional and social health benefits of these two concepts are very similar.

We will also not dwell on how to practise gratitude or positive thinking, as that would be the subject of an entire article altogether. In this article, we will stay focused on how they impact our lives.

Physical Health Benefits

• Sleep: Gratitude helps improve the quality of sleep, and this was the subject of research by the University of Manchester. The study found that when practised before bedtime, gratitude drives negative thoughts away. This makes way for positive thoughts or reflections which pave the way for a long, peaceful and uninterrupted slumber.
• Blood-pressure: There are various risk-factors for hypertension, and some of them are lifestyle related. Hypertensive people are known to indulge in smoking or alcohol more than those who do not suffer from the condition. They are known to be less health-conscious too, which constantly increases the risk for, and sustains – hypertension. When such people were encouraged to practise gratitude, they became more health or fitness oriented over time and reduced substance abuse. These factors helped neutralize hypertension and stabilize BP.
• Healthy eating: Dr. Susan Peirce Thompson is a cognitive scientist who specializes in the psychology of eating. Her study showed that when people who indulge in binge-eating or have unhealthy eating habits started practising gratitude, their will-power improved and their craving for food reduced. They could regularize their eating thereafter.
• Exercise: Studies by Emmons and McCullough looked at various benefits of practicing gratitude. They found that those who practised gratitude (by keeping a journal) were found to exercise or participate in sports more. This in turn helped sustain a positive outlook on life, thereby creating a virtuous cycle of exercise and positivity.
• Immunity: Many of the direct health benefits of practising gratitude and positive thinking stem from the fact that they help boost or strengthen the immune system. In a study conducted by Sood and Emmons, people who regularly practise these concepts showed reduced risk of contracting diseases along with an improvement in their sleep quality.
• Pain Management: According to The Sports & Spinal Group and Bruce F. Singer, Founder-Director of the Chronic Pain and Recovery Centre, people who practise Gratitude and positive thinking had better pain tolerance or reduced sensitivity to pain. These practises shift the person’s focus away from pain, on to more positive things in life.
• Diabetes Management: The practise of gratitude and positive thinking have been shown to reduce the levels of Hemoglobin A1c by 9-13%. Hemoglobin A1c is an indicator of glucose control, and lower its level is, the better is the control over blood-sugar levels and hence the ease of managing diabetes.
• Lifespan: Better immunity, increased exercise, reduced risk of disease and healthy lifestyle have a cascade effect of improving overall well-being, and thereby improving lifespan. In 2009, Boyles conducted a study involving 2 groups of women, one with a optimistic outlook to life and the other with a pessimistic one. The optimists showed only 9% risk of developing heart ailments, and a 14% reduced risk of dying, compared to cynical, hostile and pessimistic women.
• Heart ailments: A UC Davis Health study conducted in 2015 showed that patients diagnosed with congestive heart failure, who actively practise gratitude and positive thinking, showed reduced biomarkers of inflammation by 7%.

• More forgiving: Studies by Rey & Extremera in 2014 have shown that people who practise gratitude and positive thinking showed more forgiveness, tolerance to error, were less prone to judging others, less vengeful and less spiteful.
• Relieves depression: Depression is a clinical ailment that requires medication to stay under control. Studies have shown that patients who practised gratitude and positive thinking showed less of stress-inducing hormones and more of feel-good hormones. This helps in the battle against depression. Another direct benefit is that, gratitude strengthens interpersonal relationships for the patients, and this improves his/her support system.
• Overcoming addiction: Rehabilitation for drug addicts can be a long and painful process, given that such individuals are more to be self-focused in their thoughts. Training them into the practise of gratitude helps them overcome withdrawal symptoms and ease the process of de-addiction.
• More vitality: A study by McCullough and others in 2002 showed that individuals who practised gratitude had more energy and vitality in their day-to-day lives. They were also more intimate with their partners and had a better sex-life.

• Retrospective positivity: American novelist Tom Robbins said – “It’s never too late to have a happy childhood”. One may be positive in the present but unpleasant memories of the past can spoil one’s happiness. A study by Watkins and other in 2008 showed that people who practised positive thinking and gratitude were less sad about an unpleasant past and tried to see the positives in it, thereby achieving closure on many bitter memories.
• More happiness: Studies by Emmons, McCullough and Seligman in 2003 and 2005 showed that people who practised positive thinking were more able to appreciate the kindness and respect shown to them by others, and were happier individuals in the long run.
