People's emotional functioning suffers when their sleep is disrupted, study finds
Peer-reviewed – Meta-analysis - People
Losing sleep does more than just make us tired - it can undermine our emotional functioning, making us less positive and increasing our risk for anxiety symptoms, according to a new study.
"Our society is frequently sleep deprived, so understanding the effects of this on our emotions is critical to promoting good psychological health," said lead author Dr Jo Bower of the University of East Anglia.
"This study represents the most comprehensive analysis of experimental sleep and emotion research to date, and provides strong evidence that sleeping less, being awake for longer, and waking during the night can adversely influence human emotional functioning."
The study was published in the journal Psychological Bulletin by the American Psychological Association and synthesised more than 50 years of research on sleep deprivation and mood.
Dr Bower and her colleagues, including the other lead author, Dr Cara Palmer, of Montana State University, analysed data from 154 studies spanning five decades, with 5,715 total participants.
In all those studies, researchers disrupted participants' sleep for one or more nights. In some experiments, participants were kept awake for an extended period. In others, they were allowed a shorter-than-typical amount of sleep, and in others they were periodically awakened throughout the night.
Each study also measured at least one emotion-related variable after the sleep manipulation, such as participants' self-reported mood, their response to emotional stimuli, and measures of depression and anxiety symptoms.
Overall, the researchers found that all three types of sleep loss resulted in fewer positive emotions such as joy, happiness and contentment among participants, as well as increased anxiety symptoms such as a rapid heart rate and increased worrying.
"Even small amounts of sleep loss, like staying up for an extra hour or two had an impact on our emotional functioning," Dr Bower said. "We also found that sleep loss increased anxiety symptoms, and reduced arousal in response to emotional stimuli."
Findings for symptoms of depression were smaller and less consistent. The findings were also more mixed for negative emotions such as sadness, worry and stress.
One limitation to the study is the majority of participants were young adults – the average age was 23.
Future research should include a more diverse age sample to better understand how sleep deprivation affects people at different ages, according to the researchers.
Dr Bower suggests "it would also be interesting to examine how emotional functioning recovers after sleep is restored".
Other directions for future research could include examining the effects of multiple nights of sleep loss, looking at individual differences to find out why some people may be more vulnerable than others to the effects of sleep loss, and examining the effects of sleep loss across different cultures, as most of the research in the current study was conducted in the United States and Europe.
Dr Bower said: "Recent, worldwide research has shown that only 15 per cent of adults get the recommended amount of sleep for at least five nights per week. This has considerable implications for individual and public health research, including in sectors prone to sleep loss."

Former First Lady Mama Ngina Kenyatta addresses a congregation at the St. Teresa's Catholic Church in Mpeketoni, Lamu County, on Saturday, February 4, 2023.
Former First Lady Mama Ngina Kenyatta has moved to court to compel the Land Registrar to issue her with a title deed for 1,000 hectares of land based in Taita Taveta County.
In court documents filed at the Milimani High Court, obtained by Kenyans.co.ke, Mama Ngina together with former Taveta MP Basil Criticos contend that they are both co-owners of the land.
The duo, who have listed Attorney General Justin Muturi as a respondent, added that they are yet to be issued the title deed despite being the actual owners of the land.
"In breach of his said statutory obligation or duty, the 1st Respondent has to date failed to issue to the applicants (former First Lady and the MP) the said Certificate of Title in relation to the said parcel of land L.R No. 10287/7 Taveta.
"The said breach or failure by the 1st respondent (the Chief Land Registrar) denies the applicants the statutory right to have or hold the said Certificate of Title as evidence of proprietorship of their said parcel of land," read the court documents in part.
The duo wanted the matter certified as urgent.
Consequently, in orders issued by Justice John Chigiti, the matter was certified as urgent with Mama Ngina and the former MP expected to file a substantive motion within 14 days.
Muturi and the Land Registrar were also directed to file and serve their responses within 14 days after being served by the applicants.
"The Applicants shall thereafter file and serve their submissions within 14 days. The Respondents shall thereafter file and serve their submissions within 14 days of service.
"The matter shall be mentioned on March 5, 2024, to report compliance," read the orders in part. By Washington Mito, Kenyans.co.ke
Health workers at Kotido General hospital have laid down their tools over salary unpaid salaries.
The hospital remained unattended on Wednesday as the medical staff decided to stop work, citing the prolonged delay in payment of their wages.
Speaking anonymously, the medics highlighted their financial strain, emphasizing that the lack of payment for the past three months has made it impossible to sustain their families and cover essential expenses. They attribute the situation to the failure of the district to fulfill its payment obligations.
Kotido district speaker Emmanuel Lodio explained that salary delays stemmed from poor data capture by negligent officers. The strike significantly impacted health service delivery, leaving numerous patients unattended. Lodio disclosed that they formally requested the ministry of Local Government's assistance to use the funds designated for hiring secondary school teachers to clear the salary arrears.
Kotido resident district commissioner Ambrose Onoria said after discussions they agreed to operate with a reduced staff to ensure essential services continue while the district actively works to resolve the problem. - URN/The Observer
Ministers have rowed back on plans to hike the earning threshold Britons need to bring foreign family members to live in the UK to £38,700.
Instead, the Government has confirmed plans to increase the threshold to £29,000 in the spring.
Home Secretary James Cleverly had announced the increase from £18,600 to £38,700 as part of a package of measures to curb legal migration.
But the move attracted criticism as it threatened to tear families apart, with many having their future thrown into doubt as the Government considered the details of the policy.
Home Office minister Lord Sharpe of Epsom confirmed the change of plans in answer to a written parliamentary question on Thursday.
The minister said that the current threshold of £18,600 allows 75% of the UK working population to bring their foreign family members into the country to live.
He added that increasing the threshold to £38,700 would limit the same right to 30% of the working population.
Lord Sharpe said: “In spring 2024, we will raise the threshold to £29,000, that is the 25th percentile of earnings for jobs which are eligible for Skilled Worker visas, moving to the 40th percentile (currently £34,500) and finally the 50th percentile (currently £38,700 and the level at which the general skilled worker threshold is set) in the final stage of implementation.”
The minister said the threshold would be “increased in incremental stages to give predictability”.
However, no date for when the threshold would rise beyond £29,000 was given in Lord Sharpe’s answer, nor did one appear in a Home Office paper published on Thursday detailing the plans.
The Prime Minister previously told MPs the Government was looking at “transitional arrangements” for changes to the thresholds to make sure they are “fair”.
The Liberal Democrats suggested the planned £38,700 threshold was “unworkable”.
The party’s home affairs spokesman Alistair Carmichael added: “This was yet another half-thought through idea to placate the hardliners on their own back benches.
“James Cleverly needs to put down the spade and stop digging. Decisions like this should be made by experts and politicians working together.
“He should also publish the advice from the Treasury and OBR (Office for Budget Responsibility) about the impact that his package of changes will have on the economy.” By David Lynch, Evening Standard
Zanzibar's role as a trading hub emerged due to its strategic position along the maritime routes that connected the African Great Lakes, the Somali Peninsula, the Middle-East, and the Indian subcontinent. This positioning made it a natural base for traders, including those from India, seeking to engage in commerce across this vast region. Zanzibar's geographical location bridged diverse cultures and economies, including the flourishing civilizations of the Indian subcontinent.
The intricate connection between Zanzibar and India is a fabric woven, worn, and darned through centuries of historical, cultural, economic, and political interplay. The relationship between Zanzibar and India dates back to ancient times, rooted in the maritime activities of the Indian Ocean. The documented history of Zanzibar begins with its role as a base for traders voyaging between various regions, including the Indian subcontinent. Indian traders, known for their seafaring skills, were among the first to navigate these waters, reaching the East African coast, including Zanzibar, as early as the 1st century AD.
Merchants and agents from the western coast of India are noted to have visited Zanzibar in the course of prospecting trade with towns on the Swahili coast after sailing with the robust Monsoon winds, crossing the Arabian Sea and the Indian ocean. These early interactions established Zanzibar as a significant trading post in the maritime trade routes connecting it with the Indian subcontinent and laying the foundation for a robust trade network that would continue to proliferate and flourish for centuries.
By the medieval period, Zanzibar had become a pivotal point in the Indian Ocean trade network. Goods such as ivory, gold, and slaves from the African interior were traded for Indian textiles, spices, and other commodities. This trade fostered not only economic ties but also a cultural exchange, as Indian influences began to permeate Zanzibarian society. Zanzibar's commerce eventually came to be dominated by traders from the Indian subcontinent.
Under Omani rule, starting in 1698, Zanzibar's commerce increasingly fell into the hands of traders from the Indian subcontinent. Sultan Sayyid Said of Oman, who controlled Zanzibar in the first half of the 19th century, moved his capital from Muscat, Oman, to Stone Town in Zanzibar. Under his rule, the Omani Empire reached the zenith of its power and wealth, its influences spanning across the Strait of Hormuz to Iran, touching parts of modern-day Afghanistan and Pakistan. He encouraged settlers from the Indian subcontinent to reside on the island. This influx of Indian traders and settlers played a crucial role in shaping the economic and cultural landscape of Zanzibar.
Zanzibar served as an important hub in the Indian Ocean slave trade network, an equivalent to the Atlantic Triangular Trade, connecting to various regions including India. The Bantu-origin Siddi community of India whose population estimates vary from 20000 to 200000, is said to have largely been populated by immigrant slave-labourers, many of them arriving via Zanzibar. The unfortunate and deplorable practice scattered slave-labourers across West, South, and Southeast Asia in varied roles and capacities. Arab and Persian traders were prominent in the early phases of the trade, later joined by Indian and European (particularly Portuguese and Dutch) traders. With the advent of colonial powers, the oriental slave trade began to resemble its western counterpart by taking on morea attributes of the plantation or labor-camp model.
The Omani Sultan of Zanzibar's trade routes extended to what's now the states of Rajasthan, Gujarat, Maharashtra, Karnataka, and Kerala in India, bringing commodities like iron, cloth, sugar, and dates from the subcontinent and exporting slaves and goods like ivory and spices from Zanzibar.
A significant portion of such trade was secondary – items were brought in from and further sold in markets well beyond Western coastal India and Eastern coastal Africa, often flowing to and fro Arab, European, and Chinese origins and destinations. Many goods made their way to and fro Indian and African inland markets and industries to their respective coasts and subsequently into the trade channels intersecting at Zanzibar. This turned the island into a rich, dynamic, vibrant, and bustling cosmopolitan hub – a tapestry woven and rewoven by coruscating threads of myriad crossing cultures.
This period saw a rise in plantation economies and the slave trade, with Indian traders becoming integral to these sectors. Thousands of Indians were a part of this trade as slave-traders, slave-shippers, and slave-buyers. The long, narrow-hulled sailing vessel 'dhow' that was the common choice of shipping slaves and goods across the Indian ocean, was generally made in Kerala in Southwestern India owing to the abundance of high-quality timbre, coir, and skilled shipwrights.
Dhows, even in modern times, continue to voyage commercially between the Persian Gulf and East Africa, propelled solely by sails. These traditional boats predominantly carry dates and fish to East Africa, while transporting mangrove timber to the Persian Gulf regions. Typically, they journey southward, riding the monsoon winds in winter or early spring, and then return to Arabia in the late spring or early summer.
The influence of Indian merchants during this era left a lasting imprint on Zanzibar's economic landscape. The cultural landscape of Zanzibar bears significant imprints of Indian influence, primarily due to the substantial Indian diaspora that settled in the region over the centuries. These settlers, mainly comprising of traders, entrepreneurs, and later, laborers, brought with them their customs, traditions, and religions, enriching Zanzibar's patchwork sociocultural milieu.
Zanzibar once had a notable Zoroastrian presence, evidenced prominently by a fire temple, now in ruins, that served as a spiritual center for worship and community events like weddings. The relics of Zanzibar's Zoroastrian heritage include movie reels and prayer books in the temple, indicating a time when the community was actively involved in local culture and commerce, such as running a cinema. The Mwaka Kogwa festival, the island's version of the traditional Zoroastrian New Year celebration Shirazi, is one of the few remaining traces of this ancient religion in Zanzibar.
The eponymous community celebrating this are a Bantu ethnic group also known as the Mbwera. Their oral traditions narrate the story of how they originated from the Shiraz region in Southwest Iran and migrated to East Africa around the 10th century. Most historians refute any historical substance to such myths but agree that it is likely that the group came into frequent contact with Persian traders and travellers at the time.
The legend goes that Sayyid Shah, a prince from Shiraz in Persia, sailed to the East African coast in the 7th century AD at a time when Zanzibar was uninhabited. He encountered and married the daughter of the sultan ruling Mombasa at the time. Shah then went on to establish the first permanent settlements in Zanzibar, becoming its first Sultan. Furthermore, it is said he began construction on Zanzibar's iconic Stone Town modeled on the architecture of his Persian homeland. Thus, Persian and Islamic influences became long intertwined with Zanzibar's identity from that mythic journey onward.
Shah's own dynasty, the Sayyids who claimed direct descent from him all the way to the 20th century Sultans, reinforced the island's supposedly historic Persian-origin lineage.
Most historians characterize the narrative of Sayyid Shah sailing from Persia as an origin myth of the Sayyid dynasty — an artifice to link their rule to Persian royal descent and legitimise their rule, further affirming it by affecting superficial connections through the use of cultural motifs. The legendary connection serves more as rich oral tradition to explain Persian cultural influences through imaginative mythology, rather than literal migratory history. Most experts conclude it is unlikely such a founding figure actually existed in the form depicted in the legends. More likely, Zanzibar developed slowly over centuries through the migrations, trade, and intermixing of various peoples - including Persians.
Notwithstanding the veracity of the legends, elements of Persian culture nonetheless endured over the centuries in customs, language, art and architecture. Stone Town's winding alleys and ornate carved doors in particular signify the legendary early heritage tying Zanzibar to Persia across continents through exploratory travel and trade.Parsis, a Zoroastrian community from India, had a prominent presence in Zanzibar since the early 19th century. The earliest records include a Parsi man involved in the slave trade in the 1830s and two Parsi trading agents noted by Richard Francis Burton in 1859. Maneckji Mistry, a trader from Surat, is recognized as the first Parsi settler in Zanzibar, arriving in 1845.
Barghash bin Said, an Omani prince and later Sultan of Zanzibar, played a crucial role in strengthening the Parsi presence in Zanzibar. During his exile in Bombay, Barghash interacted with Parsi intellectuals and was impressed by their skills and expertise. Upon becoming Sultan in 1870, he invited Parsi specialists to Zanzibar, significantly enhancing the community's role in the archipelago. In the 1870s, Barghash expanded trade with India, employing Parsis in important administrative roles. The Zoroastrian Anjuman was founded in 1875, and by 1882, the first Zanzibari priest arrived from India. Parsis occupied significant positions, including in public works and as the Sultan's personal physician.
Under British rule, Zanzibar adopted many Indian laws, and Parsis were key figures in the legal and administrative system on the island just as they were in the subcontinent. The community, although small, was influential and integrated well into the social fabric of Zanzibar, forming relationships with other Indian communities and participating prominently in sports and cultural activities.
The Parsi community in Zanzibar was known for its generosity and involvement in social causes, both locally and in India. They contributed to the National Indian Defence Fund during the 1962 India-China War, reflecting their strong ties with India.
The illustrious musical artist Freddie Mercury was born in 1946 in Stone Town. His parents, Bomi and Jer Bulsara, were Parsis with origins in the city of Bulsar (now Valsad) in Gujarat, India. Mercury, whose birth name was Farrokh Bulsara, spent much of his early childhood in India. In February 1963, he moved back to Zanzibar to join his parents. However, just over a year later, they were forced to flee from Zanzibar to England as violence erupted during the revolution against the Sultan and his Arab-dominated government. Hundreds of Indians lost their lives while thousands more lost their livelihoods and homes as they fled the unrest. The revolution led to the exodus of most Parsis from Zanzibar, marking a sad end to their significant presence on the island.
Parsis played a crucial role in shaping the cultural and commercial landscape of Zanzibar, with their influence extending from religious practices to significant contributions in administration, trade, and social welfare. The connection between Parsis and the India-Zanzibar relationship is marked by a rich history of cultural exchange, trade, and mutual influence, underscoring the intertwined destinies of these communities and regions
Zanzibar's Stone Town, a UNESCO World Heritage site, is a testament to the Indian influence on the island's architecture, characterized by intricate balconies, wooden doors, and ornate decorations. Similarly, Indian cuisine has become an integral part of Zanzibari food culture, with dishes like biryani and samosas being local favorites.
The economic relationship between Zanzibar and India has been driven primarily by trade. In the pre-colonial era, this trade was largely in the hands of private merchants. However, in the colonial and post-colonial periods, the governments of Tanzania and India have played a significant role in fostering economic ties.
In recent years, the economic relationship has diversified, encompassing areas such as technology transfer, investment, and development aid. Indian companies have invested in various sectors in Zanzibar, including tourism, agriculture, and information technology, contributing to the island's economic development.
The political relationship between Zanzibar and India has been shaped significantly by their respective colonial histories. Both regions experienced British colonial rule, which impacted their political trajectories. In the post-colonial era, India was one of the first countries to recognize Zanzibar after its revolution in 1964 and has since maintained a strong diplomatic relationship. As India looks to consolidate its position as a strategic developmental leader in the Indian Ocean, India and Zanzibar are set for renewed cooperation, wider ties, and closer engagement.
