Summary
Low dietary fiber intake may be linked to sleep bruxism in young adults. Further research suggests increasing dietary fiber could potentially improve sleep bruxism symptoms.
Area of Science:
- Nutrition Science
- Sleep Medicine
- Oral Health
Background:
- Sleep bruxism is an under-researched condition with potential links to dietary factors.
- Identifying nutrient associations can inform preventative strategies for sleep bruxism.
Purpose of the Study:
- To identify specific nutrients associated with sleep bruxism.
- To develop a hypothesis regarding the relationship between nutrient intake and sleep bruxism.
Main Methods:
- 143 Japanese university students were categorized into sleep bruxism (n=58) and non-sleep bruxism (n=85) groups.
- A wearable electromyography device was used for sleep bruxism assessment.
- Nutrient intake was evaluated using a food frequency questionnaire.
Main Results:
- Logistic regression indicated a tendency for sleep bruxism to be associated with dietary fiber intake (OR, 0.91; p=0.059).
- A subgroup analysis revealed significantly lower dietary fiber intake in students with sleep bruxism (10.4 g) compared to those without (13.4 g; p=0.022).
Conclusions:
- Dietary fiber intake appears to be related to sleep bruxism in young adults.
- A hypothesis is proposed that increased dietary fiber intake may alleviate sleep bruxism.

01:24Substance Use Disorders Affecting Sleep
201
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:31Essential Minerals for Bone Health
4.2K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:13Insufficient Sleep and Sleep Deprivation
188
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

01:11Understanding Sleep
441
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
