It's no surprise that luck is associated with a multitude of benefits. It strengthens the immune system, makes you more resistant to pain, reduces stress and improves overall quality of life. Sadness on the other hand does not seem to do us any good and is a feeling we constantly refrain from.
There is nothing we can do to escape things that make us sad. However, we can tell you about all the surprising benefits. As science has discovered in recent years, we benefit in a much less obvious way when we are sad. Most of us do not know about it.
10 Better communication
When you are sad, it seems to be a job to talk to other people, unless it is a professional or a person close to you. It's just not something you want to do at this time. However, if you have enough willpower to do so, you will find that you are much better at conversations, when you are in a bad mood they are much more persuasive in their conversations than the funny ones and can better influence the opinion of their recipients. Sadness seems to change the way you work things, making you clearer and clearer about what you say. 
9 Improved Memory
Sadness affects the brain in ways that we do not fully understand, especially in relation to our various cognitive abilities. While it definitely has negative effects in many areas – such as analytical skills and abstract thinking – it also improves you in other things, such as memorizing.
Not a few experiments have shown that sad people can do better facial recognition and other things memory-related tasks than their happier counterparts. Surprisingly, previous studies have shown that the memory advantage does not extend to recognizing things such as objects and words, suggesting that sad people are better able to remember details (such as the face) than others. 
8 Higher Empathy
People with depression – even mild forms – are considered to be separated from the rest of the world. When it comes to empathy, one would think that happier people are better equipped and more willing to help others. However, studies show that this is not really the case.
Experiments on slightly depressed students suggest that sadness makes you more sensitive to other people's emotions. They outperformed non-depressed students in the test, which was about looking at photos and identifying emotions only by their expressions. Probably surprised by their results, they repeated the test on a larger scale and achieved the same results. While it may only mean that happiness makes you more selfish, the researchers believe that it is indeed due to the hypersensitivity to emotions in those diagnosed with depression. 
7 Better Thinking Skills
Most people do not feel like doing anything when they are sad or ill-tempered, except to sit comfortably in one place (and occasionally overeat). It is the body's natural response to emotional adversity, even though we do not understand how it helps.
However, if you've taken the trouble to do something, you'll find that this is actually the best time to do things that require thought. Research has shown that bad-tempered people are much better in terms of focus, time management, and task prioritization, but only if they are emotionally reactive. It was just the opposite for people who are less prone to negative emotions and saw a significant decline in their functional abilities in their bad phases. 
6 Higher Motivation
Sadness is traditionally associated with lack of motivation, and that too intuitively. When you're sad, you're more focused on the things that make you sad than how you can fix them. It makes sense to be sad if you are unable to find the root cause of the problem and continue to inject yourself into the cycle.
According to science, lack of motivation is not one of the side effects of sadness. In fact, studies have shown that sadness is a pretty effective motivational tool. Happy people tend to feel comfortable and less inclined to change something in their lives, which in turn can lead to stagnation or inadequacy. Sad people, on the other hand, are more inclined to get out of their situation and have a greater willingness to change for the better than others. 
5 Better for misadventures
Sadness is a natural reaction to things that are not in your favor, much like luck when you're in a good place. We are not talking about clinical depression now because it is a diagnosed disease that should definitely be treated outside the system. However, when it comes to general sadness, we all go through from time to time, depending on our specific circumstances.
Although we agree that it is a pity to be sad even occasionally, science says it actually brings an unintended benefit. A study of 2,400 subjects found that people who had experienced a misfortune in their past lives were emotionally better off than others. They can handle bad situations better than those who have never had similar experiences and are better equipped to deal with adversity later in life. 
4 Nice people are rather sad
It has long been suspected that nice people in general are rather sad about the state of the world in which they are located. Although we've never had much data to back it up, it's obvious that the nicer you are to other people, the more likely they are to be affected by their bad situations.
Studies on this topic confirm that this is absolutely true. Individuals who are more pro-social – or more conscious of others – as individuals are more likely to have symptoms of depression or develop later in life. It does not mean that you become sadder in life when you are kind and receptive to others, even though it means that inherent traits such as altruism and kindness are associated with their own side effects. 
3 Teams Under Sad Executives Are More Creative
The company manuals contain advice on how to better perform team-based tasks. Chefs are instructed to try everything – from breathing exercises to agonizing overtime – to maximize productivity. However, none of them call "being sad" as a way to motivate your team.
One study found that teams among group leaders who express much sadness are more creative than teams with relatively happy leaders. The researchers make it clear that the sadness should be authentic for it to work, or at least for the rest of the group to be authentic. However, teams of happier executives are better at analytical tasks.
As another study of sad executives revealed, sad executives are also better at targeted, long-term decision-making. 
2 Less Gullible
Because of the Internet and fake news, gullibility is a common feature among most sections of the population today. It is easier than ever to use misinformation to change a person's opinion. This tactic is used worldwide in elections. While we can not say that we know of any way to stop it – apart from promoting evidence-based skills through PSAs – we know a way to make you less gullible. just be sad.
Quite a few studies have shown that sad people are far less likely to fall for misinformation than happy ones. They are also generally more skeptical and better at detecting deceptions. In addition, a curiously specific study has found that sad people can better eliminate misleading details in eyewitness memories. 
1 Depression has given us better immunity during evolution. It is one of the most common causes of death in most countries in the world, and suicide rates are rising steadily. Against this background, depression is an anomaly. In no case it should have survived so long, as it offers no evolutionary benefits.
When interviewing evolutionary experts, depression has provided some distinct advantages during our evolution, such as increased immunity and heightened senses in emergencies. Studies have shown that people with depressive disorders also carry a specific gene that protects us from infection. In our early days, a depressive episode would have helped us stay indoors and shut down our bodies to save energy if there was a chance of being wounded or infected.
