Serotonin — The happy chemical

Serotonin is a chemical that is produced in the brain (called a neurotransmitter). It has a stabilising effect on mood, appetite, sleep, sexual function and desire, memory, and learning - to name a few.

An imbalance in Serotonin levels (in addition to other neurotransmitters) is thought to be linked to mental health conditions such as depression, anxiety and obsessive compulsive disorder (OCD). This is the theory supporting the use of SSRI’s (Selective Serotonin Reuptake Inhibitors) as the first line therapy for depression & anxiety disorders.

However, although brain serotonin production & the consequent mental illness that could result from its deficiency are largely out of our control, there are several ways that have been theorized to increase serotonin levels. These include:

1. Regular exercise: The anxiolytic (anti-anxiety) & antidepressant effects of exercise have been scientifically linked.

2. Light: Exposure to sunlight or bright light

3. Diet: A diet high in Tryptophan (responsible for the manufacture and maintenance of proteins and muscles in the body) relative to other amino acids. Tryptophan is found in high concentrations in milk.

4. Positive thoughts: Either in psychotherapy or self-induced.

During lockdown especially, depression & other mental health conditions are rife. It’s therefore important to optimize the factors that are in our control to improve our functioning. So, go for your daily lockdown walks/runs, sit outside for a bit, eat well & try to see the silver linings in each experience you are faced with. 🌞⭐️

Lastly, be kind to everyone - you never know which challenges they are facing.

Until next time 😘
