We all know that exercise promotes healthier body and better sense of well-being. It boosts confidence for people who need newer self image while it prevents the aggravation of physical illnesses for some. While nearly all of the research on exercise is focused on demonstrating positive effects on the physical body, there is a growing mass of research that seeks to prove that exercise is good for mental health as well.
A study conducted by the researchers from the Duke University along with other similar studies proved that exercise could help treat depression for 60% of all the participants. This result is similar with the total number of participants who are using medications for their treatment from depression.
However, you don’t have to be a sufferer of a mental illness before you benefit from exercise. You can boost your sense of well-being while walking on the treadmill or by combining yoga and meditation. In a way, exercise could be used as a potential medium for preventing the development of psychological and emotional conditions.
There are three dimensions at which we could look at when examining the benefits of exercise in the mental wellness of a person. Among the less well known is the biological aspect.
One theory suggests that physical workout or exercise could stimulate a part of the brain to release endorphins. Activities that are more likely to trigger the release of endorphins are swimming, cross-country skiing, running, bicycling, aerobics and sports like soccer, football and basketball.
Endorphins are comparable to opiates in a way that they resemble morphine. Endorphins could work in two ways- as a pain reliever (which is produced in response to the stresses brought about by physical work or stress) and as an enhancer of well-being. There are, however, no definite data that could support this claim.
On the other hand, exercise is also found to trigger the release of hormones norepinephrine, dopamine and serotonin. All these are known to help improve mood and is actually the main effect of Prozac, a known antidepressant.
Increase in these hormones could be best observed in a condition known as "runner's high". This feeling during after an acute exercise is directly linked to the increased number of the said hormones. However, there are still no conclusive studies proving that improvements on mood could be facilitated for a longer period of time.
Another is the physiological aspect. Nearly all of the feelings we associate with mental wellness come from our personal evaluation of the way our body feels. Say for instance, if you perceive a stomach pain as a form of stress then you will feel stressed (and sometimes even depression) every time your stomach aches. Likewise, exercise could render feelings such as muscle relaxation and easier breathing which we associate with "feeling better". While this correlation is yet to have a better scientific grounding, we still could not deny the fact that muscle tension and increased blood flow go together with physical fitness.
No one knows yet how exactly exercise affects mental health. But it is common among patients to view exercise as a good medium to elevate their moods. In fact, according to a survey conducted by the Charity Mind nearly two-thirds of all people who said that they use exercise to relieve symptoms of stress and depression believe that exercise actually works for them. The scientific community is yet to understand how this happens though and for now, it remains a truth that people benefit from exercise for mental health.

What Effects Does Nutrition Have On Mental Health
It has been an enduring belief that nutrition plays a significant role in the state of mental health of an individual. But is this true or not?
Recent as well as previous researches have proven that nutrition (or the lack of it) does have effects on how a person's brain functions, his moods and his behaviors.
Say for example, a person who has skipped a meal is observably weak, out of focus and irritable. This case worsens when extended to a certain period of time when the person becomes severely moody and indifferent to the demands of his environment thus showing decreased speed in reaction time.
These behaviors occur due to the lack of nutrition supply to the brain. The brain requires high energy and nutrient supply. It comprises, in fact, 20% to 30% of all the energy consumption of the body during rest periods. Thus, any change in diet or nutrition level of the body directly reflects in the mental functioning.
Chronic energy deprivation, such as the case of malnourished people, results to the eventual shutting down of the body by decreasing its activities and redirecting all its energy sources towards the systems that require higher energy supply. This results to altered levels of activities, changes in hormonal levels, lessened immune system efficiency and transport of nutrients and oxygen to certain body parts, all of which could directly or indirectly influence mental health. People with extremely low nutrition are more likely to become sad, depressed and emotional as compared with those who have adequate nutrition.
Newborn babies and fetuses are also susceptible to brain damage if they are subjected to lack of necessary nutrition. The type and degree of damage is dependent on the severity of malnutrition. Also, malnutrition among babies has proven to produce low level of intelligence, cognitive defects as well as functional abnormalities.
Protein, carbohydrates, lipids and vitamins all have individual effects on the brain. Lack of supply of these necessary nutrients result to alterations in the activities of the neurotransmitters, a chemical component in the brain that transmit one nerve impulse from one nerve cell to another. Malfunctioning of the transmitters could influence a person's mood, thinking and even sleep patterns. Additionally, deficient levels of nutrition may result to nerve cell damage that could disrupt cognitive and mental functions.
Neurotransmitters are partly made of amino acids, the building block of protein. Trytophan for example, makes up the neurotransmitter serotonin. If the required amino acid is lacking, the functions of the neurotransmitter could not be executed affecting the normal functioning of the brain. In case of deficient protein consumption and failure to supply the necessary amino acid to make serotonin, the body would experience low mood and perhaps, aggression. On the other hand, diseases that could cause the build up of certain amino acids could lead to brain damage thus affecting the mental health of an individual.
Mood regulation could also be associated with the sufficient intake of dietary fats. Some studies have yielded inconclusive results on the correlation between serotonin level and intake of omega-3 fatty acids, a certain type of fat found only in white fish to stress and symptoms of bipolar disorder (a mood disorder having the representations of both mania and depression).
Directly or indirectly, nutrition has an effect on mental health. Changes in the nutritional intake of a person could lead to alterations in the mental health and vice versa.
