    A cross-sectional study utilizing self-reports from Chinese college students correlated mobile phone use with insomnia, bolstering previous research that made similar conclusions.

    A study recently published in Frontiers Public Health reinforced the known correlation between mobile phone addiction and insomnia, while additionally suggesting that increasing one’s physical activity could mitigate this negative impact.

    During the COVID-19 pandemic, the use of social media was seen as a benefit both for providing social support during large-scale isolation and disseminating information on public health. However, as the authors of the current study mentioned, the negative consequences associated with mobile phone use—such as its documented influence on insomnia—should not be ignored. The authors added that investigations into the effects of mobile phone use during the pandemic have largely focused on the mental health of adolescents while the outcomes related to insomnia have been unknown.

    To address this gap in knowledge, researchers conducted a study to investigate what underlying factors influence the relationship between insomnia and mobile phone addiction in college students, considering the mediating role of social anxiety and the moderating role of physical activity. This study was conducted in China, which endured the first outbreak of COVID-19, and surveyed Chinese college students.

    This study was conducted with an online questionnaire, which was completed by 301 college students. A student’s degree of mobile phone addiction was measured with the Chinese iteration of the Mobile Phone Addiction Tendency Scale (MPATS), where higher scores indicate more intense addiction. The Chinese iteration of the Social Phobia Inventory (SPIN) was used to measure social anxiety, and higher scores indicate higher levels of social anxiety. Physical activity levels were measured with the Physical Activity Rating Scale (PARS-3) and insomnia by the Insomnia Severity Index where, similarly in both, higher scores indicate higher levels of activity and more severe insomnia.

    Their results showed that mobile phone addiction had a positive association with social anxiety (P < .001) and that social anxiety was positively associated with insomnia (P < .01). Overall, the correlation between mobile phone addiction and insomnia was found to be significant (P < .001). These findings suggested that social anxiety could be a mediator of this relationship because the indirect effect between them was also found to be significant (indirect effect = 0.03; SE = 0.01; 95% Boot CI, 0.01–0.06).

    The self-reports indicated that more physical activity could reduce both feelings of social anxiety as well as feelings of addiction to one’s mobile phone. This moderating role of physical activity on the relationship between insomnia and mobile phone addiction was found to be significant (P < .05). The authors went on to comment that physical activity has previously demonstrated to be beneficial for the management of stress and loneliness, and can improve one’s mental health. The authors’ findings were consistent with prior reports in this area.

    “But it is worth noting that social anxiety could only partially account for the relationship between mobile phone addiction and insomnia; thus other key latent indicators, such as interpersonal distress, should also considered when examining the mediation role between them afterwards,” they added.

    The limitations of the study include the inability to establish causal relationships due to the cross-sectional design, the risk of recall bias that comes with self-reported data, and the use of convenient sampling which resulted in a moderate sample size. Additionally, the exclusive focus on college students during a specific pandemic period may limit the generalizability of the findings.

    “In summary, our research results indicate that increasing physical activity and reducing social anxiety can improve insomnia symptoms among college students,” the authors concluded. “To prevent future problematic behaviors among college students, it is necessary to adopt proactive health behaviors, such as engaging in physical activity, to counteract or avoid subsequent passive impacts.”

    Sleep deprivation: A cause of high blood pressure?

    Is it true that sleep deprivation can cause high blood pressure?

    Answer From Francisco Lopez-Jimenez, M.D.

    Restless Sleep

    Possibly. Sleep experts recommend that adults get 7 to 8 hours of sleep each night. Getting less than six hours of sleep is known to be bad for overall health. Stress, jet lag, shift work and other sleep disturbances make it more likely to develop heart disease and risk factors for heart disease, including obesity and diabetes. A regular lack of sleep may lead to high blood pressure (hypertension) in children and adults.

    The less you sleep, the higher your blood pressure may go. People who sleep six hours or less may have steeper increases in blood pressure. If you already have high blood pressure, not sleeping well may make your blood pressure worse.

    It’s thought that sleep helps the body control hormones needed to control stress and metabolism. Over time, a lack of sleep could cause swings in hormones. Hormone changes can lead to high blood pressure and other risk factors for heart disease.

    Don’t try to make up for a lack of sleep with a lot of sleep. Too much sleep — although not as bad as too little sleep — can lead to high blood sugar and weight gain, which can affect heart health. Talk to your health care provider for tips on getting better sleep, especially if you have high blood pressure.

    One possible, treatable cause of lack of sleep contributing to high blood pressure is obstructive sleep apnea. This sleep disorder causes breathing to repeatedly stop and start during sleep. Talk with your care provider if you feel tired even after a full night’s sleep, especially if you snore. Obstructive sleep apnea may be the cause. Obstructive sleep apnea can increase the risk of high blood pressure and other heart problems.

    Energy Drinks Linked to Poor Sleep Quality, Insomnia Among College Students

    Male college students were found to consume more energy drinks than female college students, and they had a greater risk for a short sleep duration due to energy drink consumption.

    College students may consume energy drinks to stay alert, but the beverage may make people sleepier—a new study found energy drinks are linked to poor sleep quality and insomnia among college students.1,2

    “Even small amounts of [energy drinks] had an impact on sleep where daily [energy drinks] consumption increased the risk of sleep problems across all parameters for both sexes,” wrote the investigators.

    A study, led by Siri Kaldenbach, from the Innlandet Hospital Trust, in Lillehammer, Norway and the department of clinical medicine at the University of Oslo in Oslo, Norway, sought to investigate the frequency of energy drink consumption and the association between energy drink consumption and sleep characteristics in Norwegian college and university students. They also evaluated whether males or females consumed more energy drinks and how energy drinks affected their quality of sleep.

    The investigators conducted a cross-sectional study and obtained data from the Students’ Health and Wellbeing Study 2022 (SHOT2022), a national survey. The survey, comprised of mental health and lifestyle questions, was distributed electronically between February 8 – April 19, 2022, to full-time Norwegian students. The study included 53,266 students enrolled in higher education in Norway, aged 18 – 35 years (mean age: 24 years) with 66.4% women.

    The survey evaluated energy drink consumption, with the option of daily, 4-6 times a week, 2-3 times a week, 1 time per week, 1-3 times per month, and seldom/never. The survey also assessed sleep-related questions, and students reported usual bedtime and bed-rise time. The investigators evaluated sleep onset latency and wake after sleep onset.

    Of the participants, 4.7% of men and 3.3% of women reported consuming energy drinks daily. Moreover, men were associated with consuming more energy drinks than women. Women (49.6%) were more likely than men (39.6%) to never or seldom consumed energy drinks.

    Additionally, 5.5% of women reported consuming energy drinks 4 -6 times a week and 3.3% consumed them daily. In contrast, 7.8% of men consumed energy drinks 4-6 times a week with 4.7% consuming the drinks daily.

    Kaldenbach and colleagues observed a larger frequency of energy drink consumption was linked to sleep pattern issues such as sleep onset latency and wake-after-sleep onset. The strongest association was observed between daily energy drink consumption and short sleep duration, with men (risk ratio [RR], 2.07; 95% CI 1.77 – 2.42) exhibiting a greater risk of short sleep duration than women (RR, 1.87; 95% CI 1.64 – 2.14).

    Investigators called attention to an association between energy drink consumption and insomnia. Among women, insomnia was present among 51% reporting energy drink consumption compared to 33% among those who never or seldom consumed energy drinks. Among men, insomnia was present among 37% reporting energy drink consumption compared to 22% among those who never or seldom consumed energy drinks.

    “Most of the associations between [energy drinks] and sleep were similar for male and female students but with a few notable exceptions,” investigators wrote. “For bedtime and risetime, we observed a significantly stronger effect for men compared with women.”

    Because of the observational design, the investigators stated they could not infer causality. Moreover, the team said did not know what time the energy drink was consumed or the specific amount of the beverage—they only had access to the frequency of energy drink consumption—so that could have affected results. Another limitation, as pointed out by the team, was the “modest response rate” of 35.1% and limited information about the participants who did not complete the survey other than their age and sex.

    “The results from the current study show that there is a robust association between the frequency of [energy drinks] consumption and the different sleep parameters,” investigators wrote. “Identifying modifiable risk factors for sleep problems among college and university students is vital and our results suggest that the frequency of [energy drinks] consumption could be a possible target for interventions.”

    Why do more women struggle with insomnia than men?

    • Comments Off on Why do more women struggle with insomnia than men?

    Sleeping is an essential part of our lives. It helps us recharge for the next day. Research in this area has helped understand various sleep disorders.

    But most research has dodged the question of how different women’s sleep patterns are compared to men.

    Why is insomnia more common in women?

    The National Sleep Foundation survey, one of the first surveys in this field, found that 46% of women reported troubles with sleep almost every night. Other studies also conclude that insomnia is 40% more prevalent among women.

    A prominent reason for this difference is biological, where hormone production during pregnancy, postpartum, menopause and menstruation changes. But social and cultural reasons, like work and family, also play a role, according to the survey.

    Gender and sleep

    Gender differences have important scientific consequences. For instance, almost a decade ago, the Food and Drug Administration reduced the recommended dose of zolpidem, a drug similar to Ambien, by half for women to treat insomnia. This came after the discovery that women metabolized the drug much slower than men — which led to gender-specific guidelines.

    “It was important to raise the issue of sex differences — which is biological differences between women and men — to point out that there are differences in sleep in both the sexes,” said Dr. Monica Mallampalli, the senior scientific adviser for Healthywomen.org and a board member for Alliance of Sleep Apnea Partners.

    For example, obstructive sleep apnea, a sleep disorder in which breathing repeatedly stops and starts, is typically found in men. But women also experience it, Mallampalli explained.Report ad

    “Usually, they’re misdiagnosed or undiagnosed, and the symptoms that they present are very different than what a typical man would present,” she said, adding, “it’s also mostly hormonal.” Fibromyalgia, a condition that causes pain all over the body, has also been linked to insomnia, peaking at puberty and menopause for women, both periods of hormonal change.

    What are the types of sleep problems women face?

    1. Depression, anxiety and stress

    Sleep is often tied to mental health and women are proven to be more likely to suffer through depression and anxiety. Studies show that women are more likely to ruminate about their concerns which can hamper their ability to fall asleep or go back to sleep.

    2. Pregnancy

    According to a study, around 30% of women say they rarely sleep and more than 50% have insomnia-like symptoms. Neck and back pain paired with difficulty finding a comfortable sleeping position can disturb the quality of sleep. These problems can persist after childbirth.

    3. Obstructive sleep apnea

    Women with sleeping problems like obstructive sleep apnea are less likely to be referred to specialized sleep clinics, according to a study on gender bias in sleep disorder diagnosis. Mallampalli explained, obstructive sleep apnea is often underdiagnosed in women.

    4. Restless leg syndrome

    This syndrome creates a strong under to move limbs, especially legs, when lying down. Restless leg syndrome is also more common in men than women. Mallampalli adds that this syndrome is commonly seen in pregnant women.

    How do you improve your quality of sleep?

    Environmental stimuli such as a bright light in the bedroom, traffic noises, music, television, room temperature, pets and bedpartners can all affect sleep. The Society for Women’s Health Research created a Women & Sleep guide which suggests darkening rooms with blackout shades and drapes, turning off electronics in the room and double-paning windows for noise cancellation.

    Earplugs, eye masks and white noise machines are also extremely helpful. Caffeine and electronic gadgets should be avoided at night time, as well as stimuli like nicotine and alcohol, according to researchers.

    Mallampalli, who was involved in creating this guide, believes that by spreading awareness, more women will be able to advocate for themselves and ask their physical care physicians about sleep health. And this is how a change can begin.

    Can Oily Fish, Cherries or Milk Help You Sleep? Here’s What the Evidence Shows

    • Comments Off on Can Oily Fish, Cherries or Milk Help You Sleep? Here’s What the Evidence Shows
    • by

    James Brown, Aston University and Duane Mellor, Aston University

    Original Article | Posted by Lisa Spear | Dec 17, 2021 | Sleep & the Body

    Almost one-in-five British people report they don’t get enough sleep each night. The problem is so bad that in total the UK public are losing around a night’s worth of shut-eye each week.

    There are a lot of popular beliefs about foods and drinks helping people get a good night’s rest, but many of them are not based on scientific evidence. Here’s what we know.

    Chemistry of food and sleep

    Our diet has an influence upon sleep patterns by affecting the sleep hormone melatonin. For example, foods rich in the essential amino acid tryptophan are commonly cited as helping sleep, as tryptophan helps produce melatonin. Additionally, some vitamins and minerals may help sleep, such as vitamin D, magnesium and zinc.

    Oily fish: Evidence suggests the more oily fish, such as salmon or herring, you eat the better you sleep. Oily fish contain healthy fats such as omega-3 oils which have been shown to improve sleep in children and are involved in serotonin release. Serotonin, a brain chemical linked to mood, also regulates the sleep-wake cycle which may also explain how eating oily fish can help.

    Tart cherries: A number of studies have looked at consumption of tart cherries, usually in the form of a drink, and sleep. Evidence suggests that tart cherries improves sleep in older adults, probably due to their ability to increase melatonin levels. And tart cherries are also rich in nutrients, including magnesium, which also may improve your sleep.

    Kiwi fruit: The evidence for kiwi fruit helping you sleep is mixed. One study suggested four weeks of kiwi fruit consumption improved multiple sleep measures, while another, admittedly in sufferers of insomnia, found no effect. Based on these findings it is not clear yet that eating kiwi fruit will benefit sleep for most people.

    Oysters: In 1888 W F Nelsom wrote “He who sups on oysters is wont on that night to sleep placidly…”. There is some evidence to back up this statement, with zinc-rich foods, including oysters, being reported to benefit sleep. However, on balance eating oysters before bedtime is unlikely to be beneficial to your night’s sleep.

    Alcohol and other drinks

    Alcohol causes brain activity to slow down and has sedative effects that can induce feelings of relaxation and sleepiness> But consuming alcohol is actually linked to poor sleep quality and duration. Although drinking alcohol may cause more rapid sleep onset, this can affect the different stages of sleep, decreasing overall sleep quality. If you want a good night’s sleep, avoiding alcohol is sound advice. But are there any non-alcoholic drinks that might help?

    Warm milk: Research conducted in the 1970s suggested that a glass of warm milk before bed could improve sleep quality. This research was performed in a very small group however, and little research has been done since. Drinking milk does increase melatonin levels which could help. But there isn’t enough evidence to support the claim that a glass of warm milk definitely makes you nod off.

    Bone broth: Bone broth commonly crops up in online articles as a food that can aid sleep. This may be due its high content of the amino acid glycine. Glycine has been shown to improve sleep in rodents and humans, possibly by lowering body temperature. There are however no studies specifically looking at bone broth consumption and sleep.

    Herbal teas: The range of herbal teas aimed at the sleep market has grown and grown. Evidence for valerian, a common ingredient, to aid sleep is inconclusive. Decaffeinated green tea has been reported to improve sleep quality, which might be linked to the relaxing qualities of L-theanine, an amino acid it contains, but in general, avoiding caffeinated teas is a wise choice. If you like herbal teas, then they can be part of a relaxing pre-bedtime routine – but they are unlikely to improve your sleep quality.

    A bedtime routine

    Having a bedroom environment and daily routines that promote consistent, uninterrupted sleep are important. These include keeping to the same time to head off to bed, making your bedroom free of disruptions and having a relaxing pre-sleep routine. But many of the foods that have claimed benefits for sleep have little or no evidence behind them, to the point there are no legally recognized health claims for food assisting sleep approved in the UK or Europe.

    If any one of these things helps you to sleep well, there’s no reason to stop. But just remember the other basics of a good nights sleep too, including relaxing before bed and avoiding too much blue light from electronic devices.
