Are you the kind of a person who is always motivated and stays positive? You have an exhausting list of awesome things to do and goals to achieve.You are always busy seeking happiness in every nook and corner of life. Then here is a good news. You have a good amount of Dopamine secretion in your brain.
Dopamine is a neurotransmitter or a chemical messenger that helps in the transmission of signals in the brain and other vital areas. This chemical allows us to have feelings of bliss, pleasure, euphoria,motivation, focus and concentration.
Inside the brain, dopamine plays important roles in motor control, motivation, arousal, cognitive control, reinforcement, and reward, as well as a number of basic lower-level functions including lactation, sexual gratification, and nausea.
Dopamine motivates you to take action toward your goals, needs, and boosts the desire to achieve your goals and reinforcing pleasure when achieving them. Dopamine is produced in several areas of the brain, including the substantia nigra and the ventral tegmental area.
If the dopamine secretion is not adequate one may encounter following problems
- Poor memory, inability to focus/impaired concentration
- Mood swings
- Weight gain
- Lack of interest in life
- Decreased motivation
- Inability to feel pleasure
- Altered sleep patterns
- Restless leg syndrome
- Excessive feelings of hopelessness or guilt
- Impulsive or self-destructive behaviors
- Addictions to caffeine or other stimulants
Considerably less secretion of dopamine leads to unregulated emotional behaviour such as feeling of extreme sadness, apathy etc. Extreme deficiency can lead to neurodegenerative disorders such as as Parkinson’s disease (diminishing of motor skills, including muscle rigidity and tremors).
It is important to celebrate small achievements be it meeting a deadline or learning something new successfully. The sense of achievement leads to secretion of dopamine in the brain making you feel happy.
So what achievement are you celebrating today?
