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.

Reports have recently emerged that solariums, or sunbeds – largely banned in Australia because they increase the risk of skin cancer – are being rebranded as “collarium” sunbeds (“coll” being short for collagen).

Commercial tanning and beauty salons in Queensland, New South Wales and Victoria are marketing collariums, with manufacturers and operators claiming they provide a longer lasting tan and stimulate collagen production, among other purported benefits.

A collarium sunbed emits both UV radiation and a mix of visible wavelength colours to produce a pink or red light. Like an old-school sunbed, the user lies in it for ten to 20 minute sessions to quickly develop a tan.

But as several experts have argued, the providers’ claims about safety and effectiveness don’t stack up.

Why were sunbeds banned?

Commercial sunbeds have been illegal across Australia since 2016 (except for in the Northern Territory) under state-based radiation safety laws. It’s still legal to sell and own a sunbed for private use.

Their dangers were highlighted by young Australians including Clare Oliver who developed melanoma after using sunbeds. Oliver featured in the No Tan Is Worth Dying For campaign and died from her melanoma at age 26 in 2007.

Sunbeds lead to tanning by emitting UV radiation – as much as six times the amount of UV we’re exposed to from the summer sun. When the skin detects enough DNA damage, it boosts the production of melanin, the brown pigment that gives you the tanned look, to try to filter some UV out before it hits the DNA. This is only partially successful, providing the equivalent of two to four SPF.

Essentially, if your body is producing a tan, it has detected a significant amount of DNA damage in your skin.

Research shows people who have used sunbeds at least once have a 41% increased risk of developing melanoma, while ten or more sunbed sessions led to a 100% increased risk.

In 2008, Australian researchers estimated that each year, sunbeds caused 281 cases of melanoma, 2,572 cases of squamous cell carcinoma (another common type of skin cancer), and $3 million in heath-care costs, mostly to Medicare.

How are collarium sunbeds supposed to be different?

Australian sellers of collarium sunbeds imply they are safe, but their machine descriptions note the use of UV radiation, particularly UVA.

UVA is one part of the spectrum of UV radiation. It penetrates deeper into the skin than UVB. While UVB promotes cancer-causing mutations by discharging energy straight into the DNA strand, UVA sets off damage by creating reactive oxygen species, which are unstable compounds that react easily with many types of cell structures and molecules. These damage cell membranes, protein structures and DNA.

Evidence shows all types of sunbeds increase the risk of melanoma, including those that use only UVA.

Some manufacturers and clinics suggest the machine’s light spectrum increases UV compatibility, but it’s not clear what this means. Adding red or pink light to the mix won’t negate the harm from the UV. If you’re getting a tan, you have a significant amount of DNA damage.

Collagen claims

One particularly odd claim about collarium sunbeds is that they stimulate collagen.

Collagen is the main supportive tissue in our skin. It provides elasticity and strength, and a youthful appearance. Collagen is constantly synthesised and broken down, and when the balance between production and recycling is lost, the skin loses strength and develops wrinkles. The collagen bundles become thin and fragmented. This is a natural part of ageing, but is accelerated by UV exposure.

The reactive oxygen species generated by UVA light damage existing collagen structures and kick off a molecular chain of events that downgrades collagen-producing enzymes and increases collagen-destroying enzymes. Over time, a build-up of degraded collagen fragments in the skin promotes even more destruction.

While there is growing evidence red light therapy alone could be useful in wound healing and skin rejuvenation, the UV radiation in collarium sunbeds is likely to undo any benefit from the red light.

What about phototherapy?

There are medical treatments that use controlled UV radiation doses to treat chronic inflammatory skin diseases like psoriasis.

The anti-collagen effects of UVA can also be used to treat thickened scars and keloids. Side-effects of UV phototherapy include tanning, itchiness, dryness, cold sore virus reactivation and, notably, premature skin ageing.

These treatments use the minimum exposure necessary to treat the condition, and are usually restricted to the affected body part to minimise risks of future cancer. They are administered under medical supervision and are not recommended for people already at high risk of skin cancer, such as people with atypical moles.

So what happens now?

It looks like many collariums are just sunbeds rebranded with red light. Queensland Health is currently investigating whether these salons are breaching the state’s Radiation Safety Act, and operators could face large fines.

As the 2024 Australians of the Year – melanoma treatment pioneers Georgina Long and Richard Scolyer – highlighted in their acceptance speech, “there is nothing healthy about a tan”, and we need to stop glamorising tanning.

However, if you’re desperate for the tanned look, there is a safer and easy way to get one – out of a bottle or by visiting a salon for a spray tan.
