Can you imagine your life without emotional peaks and valleys? Sounds impossible, right? What’s possible is to increase your emotional control through enduring changes in lifestyle.
When you wake up relaxed and energized from a good night’s sleep, ready to take on the day – that’s serotonin kicking in.
When you feel depressed, overwhelmed by your daily responsibilities and challenges, you may have a deficit of serotonin.
What is serotonin?
Serotonin is a neurotransmitter that carries messages between neurons. It plays an important role in regulating your mood, controlling your appetite, helping your blood clot, helping you concentrate, regulating your body temperature, and ensuring a good night’s sleep. As a result, when we have normal levels of serotonin, we feel emotionally balanced and alert.
On the other hand, if we have low levels of serotonin, we may have trouble remembering things, feel depressed, crave sweet or starchy foods, feel anxious or irritable, have trouble sleeping or have feelings of low self-worth.
What is the link between serotonin and depression?
Researchers have linked low levels of serotonin in the brain with depression. Back in the 1960s, researchers hypothesized that low levels of serotonin in the brain led to depression. However, this hypothesis has now been debunked.
Instead, it appears that several other factors are also involved in depression. These include:
- Having a family history of depression
- Having a hectic lifestyle and having a high level of stress in your life
- Your relationships at home and in the workplace
Nevertheless, if you have low levels of serotonin, you may be at increased risk of depression. This is where SSRIs (selective serotonin reuptake inhibitors) may be helpful. SSRIs are medications which increase the uptake of serotonin in your brain.
Too much of a good thing is bad for us though. Serotonin syndrome is a potentially life-threatening condition that can occur if you take too much of an SSRI or if you take many SSRIs at the same time.
If you are looking to recharge your batteries, and need a little extra boost, here are 4 simple ways to naturally boost your serotonin levels:
Bask in bright light
When you go outside for a stretch or even just to gaze at nature, you may have noticed that you tend to come back recharged and better able to concentrate. This is because our brains produce more serotonin when we spend time in bright sunlight.
Is it cloudy outside? Still head outdoors! Even on a cloudy day, the light intensity is still typically brighter than your typical indoor lighting. Alternatively, invest in a high-intensity luxe lamp that simulates bright sunlight.
Eat a healthy diet
Adding more fruits, vegetables and legumes can contribute to a healthy gut. But did you know that having a healthy gut can also boost your serotonin levels?
More than 90% of our serotonin is produced in our digestive tract. Thus, by eating fiber-rich foods which promote gut health such as fruits, vegetables, and legumes we are naturally boosting our serotonin levels.
Foods that are high in tryptophan can also boost your serotonin levels. This is because tryptophan is converted to serotonin in your brain. What foods tend to be high in tryptophan? Protein containing foods such as nuts, lentils, tofu, chicken, fish and eggs.
However, boosting your serotonin levels is not as simple as incorporating protein-rich foods. This is because tryptophan has to compete with other amino acids, in particular the branched chain amino acids for access to our blood-brain barrier, before it can be converted to serotonin in our brain.
How can one overcome this obstacle? Eat more plant-based proteins such as seeds and nuts. Plant-based proteins contain less branched chain amino acids, hence they are better absorbed through the blood brain barrier.
Engage in regular exercise
It can be hard to get into exercise mode, particularly if you are down in the dumps. Everything seems like a struggle, particularly working up the motivation to break a sweat. When we exercise, both aerobic and strength, the activity of serotonin in the brain is revved up and the levels of tryptophan in our brain rise.
If fitting exercise into your daily routine seems too difficult, begin with baby steps. Commit to just 5 minutes of a vibrant walk a day for one week. Then the next week, increase it to 10 minutes. Before you know it, you will have built up to 30 minutes of aerobic exercise a day, and reap not only increased serotonin levels but numerous health benefits as well.
Be mindful of your thoughts
Just like the saying goes “You are what you eat”, you also become what you think! In a study conducted on healthy participants, those who were told to recall happy memories showed increased serotonin production in their brains. On the other hand, those who were told to recall sad memories showed decreased serotonin production in their brains.
It can be very tempting to ruminate on sad events when we are suffering from depression. But by finding happy things to focus on, we may be able to achieve a happier state of mind.
To think happy thoughts, begin a gratitude journal, practice mindfulness, focus on your strengths rather than your perceived weaknesses, and reminisce about the good times in your life.
Life has its ups and downs. By naturally boosting your serotonin levels, you will be able to experience more “highs” than “lows”. Start right now on the path to feeling happier, more alert, and refreshed every day.
