Rooibos could be the antidote to SA's poor sleep hygiene
Researchers say South Africans do not sleep enough, which is a public health concern as it costs the economy billions in lost productivity and car accidents while leading to health complications such as heart disease. A Stellenbosch University study showed that Rooibos could alleviate stress and anxiety to aid in a good night's rest. This is because two compounds in Rooibos interfere with the production of the stress hormone, cortisol. The lower one's cortisol levels, the higher the likelihood of uninterrupted sleep.
