An international analysis has shown how humour, used as a real hospital therapy, alleviates symptoms of anxiety, stress and depression in long-term chronic patients such as children who have just undergone surgery or even elderly people in nursing homes. The research was conducted internationally and published in the journal 'Brain and Behavior'. 

Basically, it was a review of the existing literature (quantitative, qualitative and mixed studies). Thus, in addition to existing papers, as many as 29 articles were included, involving 2964 participants, conducted in nine different countries, such as the United States, Australia, Italy, Turkey, South Korea, Iran, Israel, China and Germany.

The majority of patients, the study authors suggest, stated that humour therapy had positive effects in reducing anxiety and depression, compared to a small number of subjects who found this approach to be insignificant.

Abdominal diastasis is a problem that can affect some women in the postpartum phase. Often still considered just a cosmetic problem, abdominal diastasis actually involves a number of very uncomfortable symptoms.

When we speak of abdominal diastasis, we are referring to an enlargement and excessive separation of the central rectus abdominis muscles. The consequences of this vary depending on whether the two muscles are separated to a greater or lesser extent.

The reason why the problem occurs is mainly related to pregnancy, particularly if it is twins. However, it can also develop in men, both in cases of obesity and in cases of major weight loss. (Source: grupposandonato.it)

Parotitis is an infectious disease that is caused by a Paramyxovirus virus that is characterised by enlargement of the parotid glands located under the ears.

Like other diseases, parotitis can only be transmitted by contagion from person to person. The infection can affect individuals of any age, with complications affecting adults in particular.

When the intensity of blood directed to the brain decreases, a loss of consciousness and thus fainting may occur.

Fainting, mechanically, is manifested by a sudden loss of muscle tone, which causes a fall towards the ground, with loss of facial colouring. Before fainting, one may experience weakness, nausea and problems with vision and hearing. Usually the loss of consciousness lasts about two minutes.

The causes of fainting can be as varied as the symptoms preceding it. (Source: Humanitas Hospital Milan)
