Spending long periods in space not only leads to muscle atrophy and reductions in bone density, it also has lasting effects on the brain, suggests a study.
The study, led by a team of neuroscientists from the University of Antwerp in Belgium and Ludwig-Maximilians-University (LMU) of Munich, showed that differential changes in the three main tissue volumes of the brain remain detectable for at least half a year after the end of their last mission.
“Our results point to prolonged changes in the pattern of cerebrospinal fluid circulation over a period of at least seven months following the return to Earth,” said professor Peter zu Eulenburg from the LMU.
“However, whether or not the extensive alterations shown in the grey and the white matter lead to any changes in cognition remains unclear at present,” he added.
The study, reported in the New England Journal of Medicine, was carried out on ten cosmonauts, each of whom had spent an average of 189 days on board the International Space Station (ISS).
The magnetic resonance tomography (MRT) scans performed in the days after the return to Earth revealed that the volume of the grey matter was reduced compared to before launch.
Seven months later, this effect was partly reversed, but nevertheless still detectable.
In contrast, the volume of the cerebrospinal fluid, which fills the inner and outer cavities of the brain, increased within the cortex during long-term exposure to microgravity.
Further, the white matter tissue volume (those parts of the brain that are primarily made up of nerve fibres) appeared to be unchanged upon investigation immediately after landing.
But, the subsequent examination six months later showed a widespread reduction in volume relative to both earlier measurements.

In this case, the team postulated that over the course of a longer stint in space, the volume of the white matter may slowly be replaced by an influx of cerebrospinal fluid.
Upon return to Earth, this process is then gradually reversed, which then results in a relative reduction of white matter volume.
According to the researchers, further studies using a wider range of diagnostic methods are deemed essential, to minimise the risks associated with long-term missions and to characterise any clinical significance of the findings. (IANS)

Most teenagers use social media accounts like Facebook and Instagram these days. It keeps a person connected to friends across the globe and gives them a window into the lives of people they are connected with.
Multiple studies have shown that teenagers who use social media excessively do so because they are either bored, need an escape from their immediate physical environment, are feeling overwhelmed and stressed, are lonely, have few real-time friends or need to feel appreciated and validated.

Using social media in moderation isn't bad. In fact, it can help boost serotonin and other feel-good chemicals in the brain and can help uplift a person's mood. Most people take a selfie of themselves and post it on social media, and feel good about themselves when people like their post and comment on it. It becomes a problem when this becomes a habit. Many people feel compelled to post photos of themselves multiple times a day and then keep checking their accounts for the number of likes they have received.

Let's now go a little deeper and see the signs a person, a parent, or a loved one can look for to differentiate between social media usage and addiction. We can safely say a person is addicted to social media when we can spot some of the following:
- If a person is thinking about and talking about social media most of the time.
- If they have formed a ritual of using social media multiple times a day
- If they are using social media instead of attending to other important things in their life.
- If they are procrastinating on other important tasks and using social media instead.
- If they get frustrated and throw anger tantrums if they are unable to use social media
- If there is a fear of missing out on "life" if they don't stay connected on social media
- If social media usage has affected their studies.
- If they keep checking their social media accounts during conversations.
- If a person avoids social events to be on social media.
- If they lie about the time they spend on social media
- If they have not been able to reduce the time they spend on social media.

A Few Tips For Parents
The following things parents have found to be effective in teenage social media addiction:
- Discuss the teenager's use of social media in a non-hostile and loving manner. Keep reminding them that you are coming from a place of concern for their well-being.
- Help them to plan their day and follow the set schedule.
- Set a "no mobile phone" policy at different times of the day/night. No cell phones during meal times, while watching TV, during family time and at bedtime.
- Set tasks that require a person to be busy offline.
- Enroll them in a new hobby.
- Use less of social media yourself to set an example for your teens'.
- Seek help early from a mental health professional.
The use of social media has also resulted in many teenagers globally being subjected to name-calling, harassment, embarrassment, humiliation, stalking, threats and becoming victims of fraud through social media. It has led to a spike in teenage mental health issues and even death.
If a teenager is subjected to any form of online bullying, it can leave a lasting negative impact that can stay with the individual for years to come. The power of social media, in my opinion, is not fully comprehended by many. In school, a person may be subjected to an incident of bullying or harassment, which is usually restricted to a small group of people. Negative or derogative comments about a person posted on social media reach a wider and global audience. It is also permanent, and can be seen by all. This can really damage an individual's self-esteem and level of confidence.
There is also a correlation between excessive social media usage and mental disorders like anxiety, depression, sleep disorders, ADHD, paranoia, delusions, suicidal thoughts, and self-harm. It is very important for users to keep a check on the amount of time they spend on social media. They need to recognise the signs of social media addiction and take the necessary steps quickly to ensure they do not become addicted to social media.

How Much Time Should Someone Spend On Social Media
Studies have found that thirty minutes of social media usage helps give a boost to a person's mood, while using social media for more than two hours a day can increase the risk of developing depressive symptoms. One needs to strike a balance and use social media tools effectively. When social media platforms are used responsibly, then they become a source of enjoyment and fulfilment. They can help a person feel good about themselves, help them stay socially connected with friends globally, connect with other like-minded people, share ideas and thoughts, and stay informed of current affairs. They are also made aware of social events and have the opportunity to demonstrate their talents and skills.
What Can You Do If You Are Addicted To Social Media?
There are many effective modalities in psychotherapy that can help young adults break free from the excessive use of social media. Here are some effective tools professionals use to help people:
Counselling: Mental health counselling allows a person to explore their inner feelings and emotions in a safe and non-judgemental environment. It promotes awareness and helps a person come up with alternative options to deal with the situation.
CBT: CBT stands for Cognitive Behavioural Therapy. CBT helps a person to recognise unhelpful thoughts and the errors they are making in their thinking. A trained CBT professional help clients recognise such thoughts and help them to correct the errors they may be making in thinking. This helps to correct the behaviour and results in better moods and feelings.
Mindfulness: Mindfulness is another very effective way to help build awareness and reduce hyperactivity and restlessness. Mindfulness helps people become more grounded and cantered and recognise their feelings and emotions. Many underlying emotions are allowed to surface and be released.
It is important to connect with a mental health professional who can help in this area and help a person live a fuller and more meaningful life. Social media use and abuse has increased during the pandemic, and many are struggling to reduce time spent on social media. Sometimes it's not something a person may be able to achieve by themselves. External professional help may be required.
