Dopamine what is it

Dopamine helps nerve cells to send messages to each other. Dopamine is responsible for allowing you to feel pleasure, satisfaction and motivation. Alcohol and many illegal drugs cause a surge of dopamine too, which is partly why people get addicted to them. Dopamine also has a role to play in controlling memory, mood, sleep , learning, concentration and body movements.

Having low levels of dopamine can make you less motivated and excited about things. Having too much dopamine — or too much dopamine concentrated in some parts of the brain and not enough in other parts — is linked to being more competitive, aggressive and having poor impulse control.

It can lead to conditions that include ADHD , binge eating , addiction and gambling. Because dopamine helps control the muscles, this leads to problems with muscle stiffness and movements. You can boost a low level of dopamine by addressing the cause of the problem. This could be a mental illness , stress , not getting enough sleep, drug abuse, being obese , or eating too much sugar and saturated fat.

Low dopamine can also be caused by a problem with the adrenal glands. You can increase your dopamine levels naturally by eating a healthy diet, including foods rich in L-Tyrosine the protein needed to make dopamine. These include almonds, avocados, bananas, beef, chicken and eggs. Turmeric, vitamin D, magnesium and omega-3 supplements are also claimed to increase dopamine levels. Activities that make you feel good will also raise dopamine. These include exercising , meditating , having a massage and getting enough sleep.

Thinking about your achievements and all the good things in your life can also help. If low dopamine is causing depression or schizophrenia, your doctor may give you medicines such as antidepressants or mood stabilisers, as well as other treatments for mental illness.
