A sedentary lifestyle, smoking, and frequent drinking of alcohol contribute to degradation and reduce life expectancy. But we already know that. We also know that even malnutrition makes us stupid. However, there are non-obvious reasons that every day negatively affect the brain, including those who lead a healthy lifestyle.
Happy Worthy Life has studied the results of recent research and tells you about sudden things that badly affect our quick wits and memory.
1. Reluctance to dream
Dreams are the work of our imagination. It turned out that the brain is actively working in moments of fantasy, although it seems to a person that he is relaxed. For example, at school, teachers often scold children for thinking in the middle of a lesson about something, while continuing to listen to the teacher in half. In fact, such a “wandering consciousness” trains memory very well, including in adults.
Scientists are sure that abstract thoughts and fantasies help us remember the necessary information, even when there are many distracting factors around. How it works?
Imagine that after a friend’s get-togethers, you promise to call him when you get home. On the way, you stop to refuel and buy groceries, and then you see a car accident and get out of the car to help the injured. When after 2 hours you finally get home, you will not forget to call a friend. The ability to keep such things in the head depends precisely on the “working memory”. And she just improves from frequent fantasies.
2. Continuous operation in the brainstorm mode
One or a couple, we work as efficiently as possible, but in the group, the brain begins to degrade before our eyes. Each of us felt that after the next planning meeting there were no forces at all, thoughts were scattering, and the decision was never made. Why is this happening?
Scientists from a research institute in Virginia conducted an experiment: a group of people with an equal IQ had to work in small groups on different tasks. After working in groups, the majority of participants significantly decreased IQ, and the result of the work left much to be desired. This proves that success in work is easier to achieve alone, and it is better to refuse daily exhausting meetings.
3. Bad light
Do not linger in poorly lit rooms, and even more so – work in such conditions. The results of a new study show that dim light can weaken a person’s ability to learn and remember. Particularly bad lighting affects the elderly, as well as people with cognitive impairment.
Scientists conducted an experiment on rats and kept the animals indoors with dim light for 4 weeks. During this time, the activity of the brain department, which is responsible for learning and memory, decreased by 30% in rats. But there is good news: the same rats were then placed in a bright room, and in another 4 weeks the brain functions were completely restored.
4. GPS usage
Self-construction of a route keeps us in good shape and even helps to maintain a clear mind in old age. Using the navigator every day deprives us of this opportunity. Scientists have found that people who orient themselves in space are more active and smart than those who are used to relying on GPS.
For the same reason, it is very useful to periodically change daily routes and walk through unfamiliar neighborhoods. Such actions will not only help develop the brain, but will also become a prevention of Alzheimer’s disease.
5. Small circle of friends
Usually we are friends with people whose tastes and habits are similar to ours. Simply put, in our circle of contacts we mainly include people who are similar to ourselves. Such communication does not require complex brain activity: we feel good and comfortable, we relax and begin to think automatically.
But communication with people directly opposite us works as a way out of the comfort zone. Such contacts in the literal sense make us constantly learn new things and develop. With other people, we try to look beyond the obvious things, and this, in turn, helps us to think creatively.
6. Constant high noise
Most of us, especially residents of megalopolises, are forced to deal with loud noise every day: automobile horn, flying planes nearby, thunder in offices and cafes. We either tolerate it, or block the noise with loud music in the headphones. It turned out that a high level of noise affects not only our hearing.
A recent study showed that people with hearing loss are more likely to suffer from memory impairment and are less likely to perceive information. Therefore, you need to protect your hearing in all possible ways. For example, purchase special antinoise earbuds.
7. Internet addiction
Scientists regret that IQ levels around the world are gradually declining. Why does this happen if the level of education and new technologies in the world continues to grow? The answer is simple: we ourselves create an environment in which we stop developing.
We see no reason in remembering the facts, because there is always a phone with a search engine at hand. Therefore, even learning something new, we are unconsciously not going to keep these facts in mind: at the right time, the Internet will remind. This means that we are starting to give up real knowledge in favor of a virtual assistant who knows everything for us.
On average, a person during a conversation complains about something once a minute. The brain gets used to constant complaints and builds a kind of bridge, which leads to the fact that we begin to complain simply out of habit, without even noticing it.
It turned out that due to constant complaints, it is much more difficult for our brain to solve problems and develop intellectually. It turns out that with complaints we provoke ourselves to a single algorithm: it’s easier to suffer in public than to really change something.
9. Work in multitasking mode
But it seemed that the opposite was true: the more tasks we have, the more intensively the brain works. In fact, a person cannot qualitatively process more than one stream of information, which means that he performs all tasks superficially, without delving into them. Moreover, working in multitasking mode reduces the IQ level by as much as 15 points. This is equivalent to as if a person was forced to think after a sleepless night. By the way, constant work in this mode can lead to irreversible memory impairment and the ability to learn new things.
10. Evening workouts
Movement is necessary for our body for overall health, including for an active and keen mind. Exercise in the morning sets up for productive work and helps to start the metabolism.
But with training in the evenings, the opposite is true. Active movements increase the level of adrenaline, and our body tunes in to work, rather than to rest, so sleep after such workouts is usually shallow and intermittent. In addition, our body needs time to recover, and the body is simply forced to do this at night. As a result, we get enough sleep, lose strength, and then we think much worse during the day.
If you don’t have time to train in the morning at all, watch out for your well-being after exercise in the evening: drink more water and eat protein foods. So you protect yourself from dehydration.
Fortunately, most of these changes in the brain are reversible and just changing your habits and lifestyle a bit is enough. Moreover, some of the rules are quite pleasant, for example, chatting with interesting new people or a moment of silence over a cup of coffee.
Have you noticed how complaints affect the acumen of your friends? Do you think you can abandon such a habit?
