Large Study Examines How Everyday Drinks May Affect Depression and Anxiety

Alcoholic beverages have long shaped social settings, daily life, and the way people relax, but non alcoholic beverages and alcohol free drinks have gained attention in recent years. From non alcoholic beer and creative mocktails to sparkling water, ginger beer, alcohol free spirits, and functional beverages with natural ingredients such as lemon balm, L theanine, and lion’s mane, people now have more alcohol alternatives than ever. This growing sober curious lifestyle raises an important question about how non alcoholic drinks may relate to mental well being, physical health, and the choices people make around alcohol use.

What Are Nonalcoholic Beverages?

Nonalcoholic beverages are drinks that contain little to no alcohol, including water, coffee, tea, soft drinks, energy drinks, fruit juice, and sugar-sweetened beverages. Many of these everyday drinks contain caffeine, added sugar, artificial sweeteners, or other ingredients that can affect the brain and body. People may consume these beverages for hydration, energy, taste, or as part of their daily routine. Beverage choices can influence energy levels, sleep, mood, and stress, which may play a role in mental health. Researchers have studied whether frequent consumption of certain beverages is associated with depression, anxiety, and other mental health concerns. The effects can vary based on the type of drink, amount consumed, caffeine or sugar content, and individual health factors. Adaptogenic drinks may contain stress-supporting ashwagandha, while non-alcoholic beverages can contain up to 0.5% ABV and some alcohol-free products may contain more alcohol than labeled; kombucha’s acidity also pairs well with spicy foods.

How Nonalcoholic Beverages and Mental Health May Be Connected

Nonalcoholic beverages may affect mental health through caffeine, added sugar, artificial sweeteners, and other ingredients that influence the brain and body. These ingredients can affect sleep, energy levels, blood sugar, mood, and the body’s response to stress. Research has found associations between certain beverage habits and depression or anxiety, although diet, physical activity, sleep, genetics, and existing health conditions may also influence these relationships.

What the Large Study Found About Depression and Anxiety

A 2026 systematic review and meta-analysis examined 59 studies involving more than 2 million participants across 22 countries. Researchers found that consumption of certain nonalcoholic beverages was associated with depression and anxiety, while the findings related to stress were less consistent. Most of the available evidence was observational, so the results identify patterns rather than proving that specific beverages directly cause depression or anxiety.

Which Everyday Drinks Were Linked to Depression and Anxiety?

The researchers examined several common beverages, including coffee, tea, energy drinks, soft drinks, carbonated beverages, sugar-sweetened beverages, artificially sweetened drinks, and bubble tea. Sugar-sweetened beverages, bubble tea, carbonated drinks, soft drinks, artificially sweetened beverages, and energy drinks showed positive associations with depression in the analysis. Bubble tea and carbonated beverages were also associated with anxiety, while coffee showed a different pattern.

Sugar-Sweetened and Carbonated Beverages and Mental Health

Sugar-sweetened and carbonated beverages were positively associated with depression, while carbonated beverages were also associated with anxiety. Researchers proposed several possible explanations, including blood sugar changes, insulin resistance, inflammation, and changes in biological systems involved in the stress response. These mechanisms require further research because an association between beverage intake and mental health does not establish direct causation.

Energy Drinks and Mental Health

Energy drinks were positively associated with depression in the study, adding to concerns about how frequent consumption may relate to mental health. Many energy drinks contain substantial amounts of caffeine and added sugar, which can affect alertness, heart rate, sleep, mood, and physical responses to stress. High caffeine intake may also cause nervousness, restlessness, or anxiety symptoms, especially among people who are sensitive to stimulants.

Coffee and Tea and Mental Health

Coffee differed from several other beverage categories because higher consumption was associated with lower odds of depression. Researchers suggested that coffee’s antioxidant and anti-inflammatory compounds may contribute to this association, although the study did not establish why this pattern occurred. Coffee was not significantly associated with anxiety, and tea was also examined as researchers compared the mental health effects of different everyday beverages.

How Caffeine and Added Sugar May Affect the Brain and Mood

Caffeine stimulates the central nervous system and can temporarily increase alertness, focus, and energy. Higher intake can also contribute to restlessness, irritability, sleep problems, and anxiety symptoms, while added sugar may cause blood sugar fluctuations and affect inflammation and stress responses. Individual effects can vary based on intake, sensitivity, health, and sleep habits.

Prevalence of Depression and Anxiety

Depression and anxiety affect hundreds of millions of people worldwide. The study cited estimates of about 322 million people living with depressive disorders and 264 million living with anxiety disorders. The widespread prevalence of these conditions has increased interest in how everyday diet and beverage habits may relate to mental health.

Effects and Risks of Nonalcoholic Beverages on Mental Health

Short-Term:

• Increased energy and alertness
• Restlessness or nervousness
• Mood changes or irritability
• Blood sugar changes
• Increased heart rate
• Sleep problems
• Increased anxiety

Long-Term:

• Ongoing sleep problems
• Caffeine tolerance and dependence
• Caffeine withdrawal
• Blood sugar fluctuations
• Increased depressive symptoms
• Increased anxiety symptoms
• Mental health risks with frequent intake

Potential Mental Health Benefits of Certain Beverages

Some nonalcoholic beverages may support mental health when consumed in moderate amounts. Coffee showed a different pattern from many other drinks in the large study, with higher intake linked to lower odds of depression, while tea may also provide antioxidants and other plant compounds. Water and low-sugar beverages can also support hydration, energy, and daily functioning without adding large amounts of caffeine or sugar. Alcohol free alternatives may support healthier beverage choices, especially those with little added sugar or caffeine.

Nonalcoholic Beverages and Stress and Sleep

Beverage choices can affect both stress and sleep, especially when drinks contain caffeine or large amounts of added sugar. Research on drinking non alcoholic beer also points to benefits for stress, anxiety, and sleep. Drinking 330 ml of non-alcoholic beer daily for 14 days reduced stress, and anxiety levels also improved after two weeks. Caffeine consumed later in the day may make it harder to fall asleep or stay asleep, while poor sleep can increase irritability, stress, and anxiety symptoms. A 2022 study also linked non-alcoholic beer with improved sleep quality, and participants reported falling asleep faster. People who already have sleep problems may be more sensitive to the effects of coffee, energy drinks, tea, and other caffeinated beverages. Alcohol disrupts REM sleep, which can lead to drowsiness the next day, while matured hop bitter acids in non-alcoholic beer have been associated with better mood and sleep.

Why Adolescents May Face Greater Mental Health Risks

Adolescents may be more vulnerable to the effects of energy drinks, sugar-sweetened beverages, and high caffeine intake because their brains and sleep patterns are still developing. The study found stronger associations between certain beverage habits and mental health concerns in younger populations. School stress, irregular sleep, social pressure, and frequent access to energy drinks or sugary beverages may increase these risks.

Depression and Anxiety Signs and Risk Factors

Depression may cause persistent sadness, low motivation, fatigue, loss of interest, changes in appetite, sleep problems, or difficulty concentrating. Anxiety may cause excessive worry, restlessness, muscle tension, rapid heartbeat, irritability, and trouble sleeping. Risk factors can include genetics, trauma, chronic stress, poor sleep, medical conditions, substance use, social isolation, and major life changes.

Co-Occurring Mental Health Disorders

Depression and anxiety often occur alongside other mental health disorders. Common co-occurring conditions include bipolar disorder, post-traumatic stress disorder, obsessive-compulsive disorder, attention-deficit/hyperactivity disorder, eating disorders, panic disorder, and social anxiety disorder. Multiple conditions can make symptoms more severe and may require a broader treatment plan.

Caffeine Dependence and Withdrawal

Regular caffeine use can lead to tolerance, which means a person may need more caffeine to feel the same effect. Sudden reduction or stopping can cause withdrawal symptoms such as headache, fatigue, irritability, difficulty concentrating, low mood, and sleepiness. These symptoms are usually temporary but can make it harder for some people to reduce their caffeine intake.

Beverage Habits, Alcohol Use Disorder, Substance Use, and Addiction

Beverage habits can overlap with the use of alcohol, nicotine, cannabis, stimulants, opioids, benzodiazepines, and other substances. Some people may use caffeine to stay awake after drinking alcohol or using sedating drugs, while others may combine energy drinks with alcohol, which can reduce the feeling of intoxication without reducing impairment. Frequent use of substances to manage mood, energy, sleep, or stress can increase the risk of dependence and addiction.

Co-Occurring Addiction, Mental Health Disorders, and Everyday Drinks

Substance use disorders often occur with depression, anxiety, PTSD, and bipolar disorder, and some people may use alcohol, cannabis, stimulants, opioids, or sedatives to cope with symptoms. Current research does not prove that nonalcoholic beverages directly cause depression or anxiety, since diet, sleep, stress, health conditions, and substance use may also affect the findings. More research is needed to understand these relationships, while treating co-occurring mental health and substance use disorders together may improve stability and reduce relapse risk.

Study Limitations and What the Findings Mean

Many studies included in the analysis were observational or cross-sectional, which means researchers could identify patterns but could not prove cause and effect. Beverage intake was often self-reported, and factors such as diet, physical activity, smoking, income, and sleep may have influenced the findings. The results suggest that beverage habits may matter for mental health, but they should be viewed as one part of a larger picture.

Benefits of Mental Health Treatment

• Better symptom management
• Improved sleep and daily functioning
• Healthier coping skills
• Reduced anxiety and depression symptoms
• Stronger relationships
• Better stress management
• Lower risk of substance misuse
• Improved quality of life

When to Seek Help

A person should consider professional help when depression, anxiety, stress, sleep problems, or substance use begin to interfere with work, school, relationships, or daily responsibilities. Help is also important when symptoms continue for weeks, become more severe, or lead to thoughts of self-harm. Early support can reduce the impact of symptoms and help prevent problems from getting worse.

Treatment for Co-Occurring Mental Health and Substance Use Disorders

• Individual Therapy: Addresses mental health symptoms, substance use, and triggers.
• Cognitive Behavioral Therapy: Builds healthier thoughts and coping skills.
• Dialectical Behavior Therapy: Supports emotional regulation and distress tolerance.
• Medication Management: Treats certain mental health symptoms when appropriate.
• Substance Use Counseling: Addresses cravings, triggers, and relapse prevention.
• Group Therapy: Provides support and coping skills.
• Residential Treatment: Provides 24-hour structured care.
• Partial Hospitalization Programs: Provide intensive daytime treatment.
• Intensive Outpatient Programs: Provide structured treatment with greater daily flexibility.

Does Insurance Cover Treatment?

Many insurance plans cover mental health and substance use treatment, including therapy, medication management, outpatient programs, and residential care. Coverage varies by plan, provider, diagnosis, and level of care, so patients should verify benefits and in-network requirements before treatment.

Conclusion

Research shows that beverage choices may have positive effects, potential benefits, and negative health effects depending on alcohol content, caffeine, sugar, nutrition, and individual health issues. Alcohol free beverages, non alcoholic cocktails, and other non alcoholic options can offer alternatives to traditional alcoholic beverages, beer, wine, soda, and alcoholic cocktails, but trace amounts of alcohol or familiar flavors may trigger cravings for some people with alcohol use disorder or in early recovery. As health sciences and National Institute research continue to examine alcohol consumption, dopamine release, mental clarity, better sleep, decreased risk, and emotional distress, most studies support looking at each drink within the larger social context rather than assuming that every choice without alcohol has the same effects.
