According to the World Health Organization, about 280 million people worldwide have depression and about one billion have a mental health problem of any kind.

People living in the ancient world also had mental health problems. So, how did they deal with them?

As we’ll see, some of their insights about mental health are still relevant today, even though we might question some of their methods.

1. Our mental state is important

Mental health problems such as depression were familiar to people in the ancient world. Homer, the poet famous for the Iliad and Odyssey who lived around the eighth century BC, apparently died after wasting away from depression.

Already in the late fifth century BC, ancient Greek doctors recognised that our health partly depends on the state of our thoughts.

In the Epidemics, a medical text written in around 400BC, an anonymous doctor wrote that our habits about our thinking (as well as our lifestyle, clothing and housing, physical activity and sex) are the main determinants of our health.

2. Mental health problems can make us ill

Also writing in the Epidemics, an anonymous doctor described one of his patients, Parmeniscus, whose mental state became so bad he grew delirious, and eventually could not speak. He stayed in bed for 14 days before he was cured. We’re not told how.

Later, the famous doctor Galen of Pergamum (129-216AD) observed that people often become sick because of a bad mental state:

It may be that under certain circumstances ‘thinking’ is one of the causes that bring about health or disease because people who get angry about everything and become confused, distressed and frightened for the slightest reason often fall ill for this reason and have a hard time getting over these illnesses.

Galen also described some of his patients who suffered with their mental health, including some who became seriously ill and died. One man had lost money:

He developed a fever that stayed with him for a long time. In his sleep he scolded himself for his loss, regretted it and was agitated until he woke up. While he was awake he continued to waste away from grief. He then became delirious and developed brain fever. He finally fell into a delirium that was obvious from what he said, and he remained in this state until he died.

3. Mental illness can be prevented and treated

In the ancient world, people had many different ways to prevent or treat mental illness.

The philosopher Aristippus, who lived in the fifth century BC, used to advise people to focus on the present to avoid mental disturbance:

concentrate one’s mind on the day, and indeed on that part of the day in which one is acting or thinking. Only the present belongs to us, not the past nor what is anticipated. The former has ceased to exist, and it is uncertain if the latter will exist.

The philosopher Clinias, who lived in the fourth century BC, said that whenever he realised he was becoming angry, he would go and play music on his lyre to calm himself.

Doctors had their own approaches to dealing with mental health problems. Many recommended patients change their lifestyles to adjust their mental states. They advised people to take up a new regime of exercise, adopt a different diet, go travelling by sea, listen to the lectures of philosophers, play games (such as draughts/checkers), and do mental exercises equivalent to the modern crossword or sudoku.

For instance, the physician Caelius Aurelianus (fifth century AD) thought patients suffering from insanity could benefit from a varied diet including fruit and mild wine.

Doctors also advised people to take plant-based medications. For example, the herb hellebore was given to people suffering from paranoia. However, ancient doctors recognised that hellebore could be dangerous as it sometimes induced toxic spasms, killing patients.

Other doctors, such as Galen, had a slightly different view. He believed mental problems were caused by some idea that had taken hold of the mind. He believed mental problems could be cured if this idea was removed from the mind and wrote:

a person whose illness is caused by thinking is only cured by taking care of the false idea that has taken over his mind, not by foods, drinks, [clothing, housing], baths, walking and other such (measures).

Galen thought it was best to deflect his patients’ thoughts away from these false ideas by putting new ideas and emotions in their minds:

I put fear of losing money, political intrigue, drinking poison or other such things in the hearts of others to deflect their thoughts to these things […] In others one should arouse indignation about an injustice, love of rivalry, and the desire to beat others depending on each person’s interest.

4. Addressing mental health needs effort

Generally speaking, the ancients believed keeping our mental state healthy required effort. If we were anxious or angry or despondent, then we needed to do something that brought us the opposite of those emotions.

This can be achieved, they thought, by doing some activity that directly countered the emotions we are experiencing.

For example, Caelius Aurelianus said people suffering from depression should do activities that caused them to laugh and be happy, such as going to see a comedy at the theatre.

However, the ancients did not believe any single activity was enough to make our mental state become healthy. The important thing was to make a wholesale change to one’s way of living and thinking.

When it comes to experiencing mental health problems, we clearly have a lot in common with our ancient ancestors. Much of what they said seems as relevant now as it did 2,000 years ago, even if we use different methods and medicines today.

Sea moss is the latest “superfood” wellness influencers are swearing by. They claim sea moss products – usually in gel form – have multiple health benefits. These include supporting brain and immune function, or protecting against viruses and other microbes.

But do these health claims stack up? Let’s take a look.

What is sea moss?

Sea moss is produced using a kind of seaweed – particularly red algae – that grow in various locations all around the world. Three main species are used in sea moss products:

• Chondrus crispus (known as Irish moss or carrageenan moss)
• Eucheuma cottonii (sea moss or seabird’s nest)
• Gracilaria (Irish moss or ogonori).

Some products also contain the brown algae Fucus vesiculosus (commonly known as bladderwrack, black tang, rockweed, sea grapes, bladder fucus, sea oak, cut weed, dyers fucus, red fucus or rock wrack).

Most sea moss products are sold as a gel that can be added to recipes, used in smoothies, frozen into ice cubes or eaten on its own. The products also come in capsule form or can be purchased “raw” and used to make your own gels at home.

What’s the evidence?

Sea moss products claim a host of potential health benefits, from supporting immunity, to promoting skin health and enhancing mood and focus, among many others.

But is there any evidence supporting these claims?

Recent studies have reviewed the biological properties of the main sea moss species (Chondrus crispus, Eucheuma cottonii, Gracilaria and Fucus vesiculosus).

They suggest these species may have anti-inflammatory, antioxidant, anticancer, antidiabetic and probiotic properties.

However, the vast majority of research relating to Chondrus crispus, Gracilaria and Fucus vesiculosus – and all of the research on Eucheuma cottonii – comes from studies done in test tubes or using cell and animal models. We should not assume the health effects seen would be the same in humans.

In cell and animal studies, researchers usually administer algae in a laboratory and use specific extracts rich in bioactive compounds rather than commercially available sea moss products.

They also use very different – often relatively larger – amounts compared to what someone would typically consume when they eat sea moss products.

This means the existing studies can’t tell us about the human body’s processes when eating and digesting sea moss.

Sea moss may have similar effects in humans. But so far there is very little evidence people who consume sea moss will experience any of the claimed health benefits.

Nutritional value

Eating sea moss does not replace the need for a balanced diet, including a variety of fruits and vegetables.

Chondrus crispus, Eucheuma cottonii and Gracilaria, like many seaweeds, are rich sources of nutrients such as fatty acids, amino acids, vitamin C and minerals. These nutrients are also likely to be present in sea moss, although some may be lost during the preparation of the product (for example, soaking may reduce vitamin C content), and those that remain could be present in relatively low quantities.

There are claims that sea moss may be harmful for people with thyroid problems. This relates to the relationship between thyroid function and iodine. The algae used to make sea moss are notable sources of iodine and excess iodine intake can contribute to thyroid problems, particularly for people with pre-existing conditions. That is why these products often carry disclaimers related to iodine sensitivity or thyroid health.

Is it worth it?

So you may be wondering if it’s worth trying sea moss. Here are a few things to consider before you decide whether to start scooping sea moss into your smoothies.

A 375mL jar costs around $A25–$30 and lasts about seven to ten days, if you follow the recommended serving suggestion of two tablespoons per day. This makes it a relatively expensive source of nutrients.

Sea moss is often hyped for containing 92 different minerals. While there may be 92 minerals present, the amount of minerals in the algae will vary depending on growing location and conditions.

The efficiency with which minerals from algae can be absorbed and used by the body also varies for different minerals. For example, sodium is absorbed well, while only about 50% of iodine is absorbed.

But sea moss has also been shown to contain lead, mercury and other heavy metals – as well as radioactive elements (such as radon) that can be harmful to humans. Seaweeds are known for their ability to accumulate minerals from their environment, regardless of whether these are beneficial or harmful for human nutrition. Remember, more doesn’t always mean better.

What else am I eating?

While you won’t get a full nutritional breakdown on the jar, it is always wise to check what other ingredients you may be eating. Sea moss products can contain a range of other ingredients, such as lime, monk fruit powder, spirulina and ginger, among many others.

These ingredients differ between brands and products, so be aware of your needs and always check.

Despite their health claims, most sea moss products also carry disclaimers indicating that the products are not intended to diagnose, treat, cure or prevent any disease.

If you have concerns about your health, always speak to a health professional for accurate and personalised medical advice.
