Everything You Need to Know About Feeling Sad – And What You Can Do to Feel Better

Feeling sad is something that happens to all of us. Your football team loses, you fall out with a friend, or something much worse happens, and it can feel like a smile is a distant memory. But what is sadness, and what actually happens to us when we feel sad? 

What does serotonin do? 

So this tricky little neurotransmitter in our brains is what is responsible for us feeling sad, called serotonin. A neurotransmitter essentially carries signals around our brain that controls how we feel. So, serotonin’s job is to deliver emotions and carry messages about our mood, and it’s often labelled as the ‘feel good’ neurotransmitter. It also transmits signals which help wounds to heal, and which help our digestive system to function normally.

We all have an evolutionary response to stuff that happens with us, to fight, flight or freeze. Serotonin is responsible for the freeze response in humans.

So, this is why we get depression? 

There is a definite link between low serotonin levels and sadness and depression. But having less serotonin doesn’t always mean you get depression. The brains of teenagers typically have a little less serotonin than adults, which means it’s harder to process emotions, and which is probably why we all feel a bit crap when we’re teenagers. 

Why do we want to increase it? 

Even though it might seem like we don’t have a huge amount of control over what goes in our brains at times, increasing serotonin levels is important if we have a deficiency given its link to depression, anxiety and other mental health conditions. Doing things to naturally boost serotonin will boost our general mood and having good levels of serotonin also means we literally heal from wounds faster, so it’s basically a super power. 

It’s important to know though that being sad, or feeling the effects of depression, is not a sign of weakness. If you need to talk to someone, reach out to our community here for free confidential support and advice. 

How do we do it then? 

  • Exercise every day – it boosts serotonin in your brain and some studies have demonstrated that exercise is at least equally effective at increasing available serotonin as serotonin-enhancing medications
  • Get your gut healthy – Much of the serotonin in your body is produced in your gut 
  • Watch what you eat – Foods high in simple carbohydrates, such as pasta, potatoes, bread, pastries, pretzels, and popcorn, typically increase insulin levels and allow more tryptophan (the natural amino acid building block for serotonin) to enter the brain, where the brain cells can convert it to serotonin. 
  • Light – some research suggests that serotonin tends to be lower after winter and higher in summer and fall. Serotonin’s known impact on mood helps support a link between this finding and the occurrence of seasonal affective disorder and mental health concerns linked to the seasons.
