Full Transcript Introduction to Energy Drinks 0:00 This one drink has caused psychosis, hypomania, mania and or depression in my patients. 0:14 Hey, I'm Dr. 0:15 Uma Naidu. 0:16 I am a Harvard nutritional psychiatrist and I wanted to tell you today about energy drinks, a question I get all the time. 0:27 Now energy drinks are popular beverages that claim to boost energy, alertness and physical or mental performance. 0:35 They usually contain caffeine, refined sugars, B vitamins and other ingredients like taurine or guarana. 0:43 But even though those may be healthy ingredients, the earlier ones like caffeine and sugar are less healthy. 0:51 How do energy drink affect the nervous system and mood? 0:55 The main active ingredient in most energy drinks is caffeine.
Caffeine and Sugar Effects 1:00 Caffeine is a stimulant, which means it speeds up the brain and body. 1:05 After drinking an energy drink, people often feel more awake, alert and energetic for a short time. 1:12 However, these effects can be followed by side effects such as feeling jittery, anxious, restless or having trouble sleeping. 1:20 They also experience headaches, stomach upset or fast heartbeat. 1:25 Well, what about the sugar content? 1:29 Many energy drinks contain a lot of sugar, sometimes more than the recommended daily amount in just one can. 1:38 Sugar can give a quick burst of energy, but this is often followed by a crash, which can make people feel irritable, tired or very moody. 1:48 Regularly drinking these sugary energy drink can also lead to weight gain, dental problems and the increased risk of type 2 diabetes. 1:57 Now you may ask, do energy drinks offer any nutritional benefit? 2:03 Energy drinks may contain B vitamins and other nutrients but usually these are not needed if a person eats a balanced diet and they are often used more 2:12 for marketing than for anything else. 2:15 Does this mean they're bad? 2:17 No. 2:17 Those added vitamins may be good for your body but guess what? 2:21 They are masked by the high caffeine and high sugar in these drinks. 2:26 The main effects of energy drinks come from caffeine or sugar, not from the vitamins or other ingredients. 2:33 There is no evidence that energy drinks provide any real health or nutritional benefit, and they are not recommended as a way to improve nutrition. 2:42 Now, are there risks for people with mood disorders like bipolar disorder? 2:48 People with Mood Disorders like Bipolar Disorder may be more sensitive to the effects of caffeine in energy drink.
Limited Nutritional Value 2:55 There are reports that Energy drinks can trigger manic or depressive episodes in some people especially if consumed in large amounts or over several days. 3:08 Energy drinks can also worsen anxiety and sleep problems and mood swings in people with or without a history of mental health issues. 3:17 Now what about teens and young adults? 3:20 Energy Drinks are especially popular among teenagers and adults. 3:24 However, these groups are also at higher risk for the negative effects, including poor sleep increased stress, depression and even thoughts of self-harm 3:35 or suicide if energy drinks are consumed too often, and there's research behind this. 3:41 The American College of Sports Medicine and other experts recommend that children and teenagers avoid energy drink.
Mood Disorder Risks 3:49 What are some key points to remember? 3:52 Energy drinks can make people feel more alert for a short time, but they may also cause anxiety and sleep problems, as well as mood swings. 4:02 The sugar in energy drinks can lead to a quick energy boost but followed by a crash and regular use can cause health problems. 4:12 There's no meaningful nutritional benefit to drinking energy drink if a person eats a healthy, balanced, whole foods diet. 4:20 People with mood disorders such as bipolar disorder or depression may be at higher risk for negative effects, including triggering a manic or depressive episode. 4:31 Children and teens and people with certain health conditions should avoid energy drinks. 4:37 Now the stimulant effect of energy drink affects one's nervous system and mood. 4:41 Caffeine, which antagonizes adenosine receptors leading to increased alertness, reduced fatigue and improved reaction time. 4:50 These effects are dose dependent with benefits most pronounced at caffeine doses of greater than and equal to 3 mg per kilogram of body weight. 5:00 However, adverse neurological and psychiatric effects, including anxiety, agitation, poor sleep and psychomotor disturbances are frequently reported, 5:11 especially in children, adolescents and caffeine-naive individuals. 5:18 The American College of Sports Medicine highlights that neurological and psychiatric adverse events are among the most common with energy drink use. 5:28 So chronic or frequent consumption of sugar-sweetened energy drinks is associated with increased risk of stress, depression,
Risks for Teens and Young Adults 5:36 anxiety, and suicidal ideation. 5:38 particularly in adolescents and young adults. 5:42 Animal studies suggest that the combination of caffeine and sugar may exacerbate anxiety-like behaviors and promote emotional and cognitive alterations 5:52 compared to sugar alone. 5:55 Both caffeine and sugar contribute to the rewarding properties and potential for repeated use of these energy drinks. 6:02 But regular intake of high sugary drinks with a lot of caffeine is consistently linked to poor metabolic and psychiatric outcomes. 6:12 So please look at energy drink for the caffeine & sugar content when assessing the risk. 6:20 Energy drinks acutely enhance alertness and mood via central nervous system stimulation, but they also elevate blood sugar. 6:29 When frequently used, the excessive intake is associated with increased risk of anxiety, depression and neuropsychiatric disturbances,
Key Takeaways on Health Effects 6:38 especially in youth. 6:40 Individuals with mood disorders, including bipolar disorder, may be more susceptible to adverse psychiatric effects from energy drinks and caffeine. 6:49 Things that can happen include triggering manic and depressive episodes, a relapse of psychosis or exacerbation of mood symptoms. 6:57 Clinical observations and case reports document manic or depressive relapses in bipolar patients following periods of excessive energy drink consumption, 7:08 with some cases involving daily intake of multiple cans over a week. 7:13 Acute or excessive caffeine intake from energy drinks can induce or worsen mania, hypomania anxiety and sleep disruption, 7:23 all of which may destabilize mood in vulnerable individuals. 7:27 High episodic consumption, especially above 200 mg of caffeine per occasion, is associated with increased risk of psychiatric symptoms,
Caffeine, Sleep, and Psychiatric Symptoms 7:38 including agitation and insomnia. 7:41 Sleep disruption is a key mediator of negative mood effects. 7:46 Caffeine intake is associate with shorter sleep duration, which in turn predicts next day increases in depressive and hypomanic symptoms. 7:55 Recent longitudinal data suggests that these effects are not necessarily more pronounced in those with bipolar spectrum disorders compared to controls, 8:05 although case reports and clinical observations indicate a potential risk for mood destabilization in this population. 8:15 In summary, the stimulant effects of energy drinks can potentially trigger dangerous mood elevations or exacerbate symptoms in people with mood disorders, 8:24 particularly with high acute intake, but the magnitude or risk compared to the general population remains uncertain due to limited prospective data. 8:34 So in summary, while energy drinks on occasion once in a while may be somewhat okay, I would not recommend drinking these on any regular basis. 8:45 and especially not if you have been diagnosed with a mental health condition such as bipolar disorder, hypomania, psychosis or even depression.
