Brain health and social media
During the past decade, online social networking has caused profound changes in the way people communicate and interact. More and more of us are spending time on our phones, computers and tablets; whether that is for work or communicating with our friends. But how is such a switch in how we live and communicate having on both our brain and our mental health?
Evidence is growing in this area, with researchers beginning to determine just how our daily use of technology affects our brains, particularly in adolescents. Research suggests an association between greater social media use and higher depressive and anxiety scores, poor sleep quality, low self-esteem and body image concerns. Several studies have indicated that the prolonged use of social networking sites may be related to signs and symptoms of depression and low self-esteem. A recent study found a link between use of multiple social media platforms and increased depression and anxiety symptoms in young people. The latest data shows that during the strict lockdown period here in the UK, adults spend almost double the time on their phones as they did pre-lockdown!
When it comes to shaping our brains our environment plays a big role, and as technology continues to grow, it affects us in ways that you may not have thought. Using technology affects our memory, our attention, what we focus on and our sleep cycles, which in time can have long term impacts on both the brain and our mental health.
Mental health and social media
Humans are social, and social media is easily accessible for everyone 24/7.. We need the companionship of others to thrive in life, and the strength of our connections has a huge impact on our mental health and happiness. Being socially connected to others can ease stress, anxiety, and depression, boost self-worth, and can prevent loneliness. But, on the flip side, lacking strong social connections and spending too much time on social media platforms may not be so good for long-term mental and emotional health.
As use of social media continues to rise, it is estimated that by 2021, over 3 billion people will be using it
Screen time and the brain
Take social media out of the equation, and we’ll still find screens wherever we look. Whether it be checking your travel app to find the time of the next train, watching your favourite TV program before bed or setting your alarm on your phone for the next morning. It’s hard to escape screen-time in the modern world that we live in, but how is all this screen time actually affecting our brains?
Increasing the amount of screen times results in an increased exposure to blue light. Blue light is found in many energy efficient light sources and digital devices. It has a short wavelength that stimulates sensors in the eyes to send signals to your brain’s internal clock, tricking it into thinking it's daytime. Light is the most powerful cue for shifting the phase or resetting the time of the circadian clock. In an evening, the blue light that emits from devices (including TVs) suppresses the natural production of melatonin – the hormone you need to feel sleepy – and plays havoc with your body’s circadian rhythm making, it harder to fall asleep and stay asleep.
The blue light coming from any screen has been shown to impact certain areas, most notably disrupting sleeping patterns. Blue light has been shown to penetrate all the way to the retina (the inner lining of the back of the eye) and studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina.

With this in mind, how can we stop spending so much time on our screens and safeguard our brain health for the years to come? Well, look no further! We’ve got some tried and tested tips to help give your brain a break and help to boost your mood!

See your friends face-to-face
Social media is brilliant for communicating with each other, but don’t let it stop you from getting together with your friends face-to-face. Not only will it be great to see them, you guessed it, it’ll distract you from spending time on your social media.
