product descriptions

TikTok is a social media platform that emphasizes short-form video content. Users create, share, and discover short-form videos set to music or other audio backtracks. TikTok’s central feature is the ability to record and edit videos, typically ranging from 15 seconds to one minute in length. In concurrence, users can apply various effects, filters, and music to their videos to stimulate engagement with other users.

product use

The central screen of TikTok is the “For You Page,” where users are presented with a continuous feed of short-form videos. TikTok’s algorithm curates these videos based on the user’s interests, interactions, and trending content. Users can scroll vertically to navigate through the videos. Furthermore, there is a bottom navigation bar: Home Icon, search icon, camera icon, notifications icon, and profile icon. Each icon provides a quick shortcut to get to a designated place on the app.

who’s affected

TikTok is available to everyone 13 years and older. Thirty-three (33) percent of American adults overall use Snapchat, but it is used by 62% of those aged 18-29. Women (40%) are more likely to use Snapchat than men (25%) and Hispanic (49%) and Black Americans (39%) are more likely to use it than Asian Americans (29%) and Whites (29%).(1)

influence on health-related behaviors

EATING

neutral to slight negative influence

Social media platforms generally, and TikTok in particular, can affect users’ eating habits in at least three ways: 1) users can literally eat while they are using the site; 2) users can be influenced by the behaviors and the content that they see on the site; 3) time spent on the platform can reduce the time available to obtain and prepare healthy meals.

With regards to the first, Building H’s consumer research found that 20% of adult(2) TikTok users report snacking “always or almost always” when they’re on social media, 29% reported doing so “frequently” and 36% “sometimes.” Fifty (50) percent of heavy TikTok users (defined as those using TikTok two or more hours per day) reported their snacks as mostly or always healthy. Comparatively, 86% of ‘light’ users of social media (defined as those who don’t use any one social platform for more than thirty minutes per day) reported their snacks as mostly or always healthy.(3)

Exposure to influencers, images, information, and advertisements can significantly prompt our perception of how, what and when we eat. One study of social media users found that people who spend more time on social media each day (not specific TikTok) are 2.2 times more likely to report eating concerns. The most frequent users were 2.6 times more likely.(4)

On the other hand, social media platforms can also equip users with abundant information on wholesome recipes, nutritional tips, and meal preparation. This accessibility can aid individuals in making more sound, suitable, guided choices about their diet. Similarly, online communities and groups devoted to health and wellness provide support, encouragement, and accountability. 

Our consumer research found that 54% of TikTok users reported that their use of social media has not had a significant influence on their diet. Thirty-six (36) percent of TikTok users and 44% of heavy TikTok users reported that social media had influenced them to eat healthier, while 10% of TikTok users (and 13% of heavy TikTok users) reported a negative influence on their diet.(5)

A meta-analysis of studies on social media and diet for children and adolescents found that most studies reported that social media (not specific to TikTok) was associated with skipping breakfast, increased intake of unhealthy snacks and sugar-sweetened beverages, and lower fruit and vegetable intake.(6)

Building H’s consumer research also found that use of TikTok is associated with how and what people eat. Fifty-two (52) percent of heavy TikTok users eat three (3) or more fast food meals per week; in comparison — only 11% of 'light' and 16% of 'moderate' (defined as those who do not spend more than an hour per day on any one social media platform) social media users eat three (3) or more fast food meals per week.(7) Note that researchers have found 70% of meals served at fast food restaurants to be of poor nutritional quality.(8) 

Heavy TikTok users tend to get meals delivered more often. Forty-four (44) percent of heavy TikTok users get three (3) or more meals delivered per week. Comparatively, only 7% of 'light' and 9% of 'moderate' users of social media get food delivered three (3) or more times per week.(9) 

Finally, 31% of heavy TikTok users eat six (6) or more home cooked meals per week, compared with 51% of  ‘light’ and 47% of ‘moderate’ social media users.(10) Home-cooked meals have in general been shown to be healthier than meals eaten out or ordered from restaurants.(11-15) People who cook at home more frequently also tend to have diets that have higher compliance with dietary guidelines.(16)

PHYSICAL ACTVITY

slight negative influence

Using TikTok is a largely sedentary activity. People use TikTok by accessing it on a computer or a mobile device, such as a smartphone or a tablet. Even use of smartphones, despite their inherent mobility, tends to be sedentary – studies have found that 80-90% of smartphone use occurs while sitting.(17-19)

Time spent using TikTok and other social media platforms can potentially reduce the time available for physical activity. While a moderate amount of social media would leave time for more active pursuits, Building H’s consumer research found that 42% of TikTok (adult) users reported using the platform more than an hour per day, with 25% using it for more than two hours per day.(20) Thirty-two (32) percent of teens report using TikTok several times a day and an additional 17% report using it “almost constantly.”(21) For many TikTok users, time spent on TikTok represents a large share of the approximately five hours per day of leisure time Americans have on average.(22)

TikTok utilizes several design features that encourage users to frequent their platform more regularly and to spend more time on the platform once they’re there. These features include: infinite scroll; algorithmically curated feed; social rewards; and notifications. 

• TikTok uses an infinite scroll, which permits a never-ending stream of posts, videos, and updates. 

• The algorithmically curated feed seeks to personalize and prioritize content delivered to each user on their timeline. Their algorithms scrutinize a multitude of factors, such as the user's past interactions, interests, content engagement, and the popularity of posts, to determine what content to display.

• TikTok uses “likes” and other peer feedback systems to encourage greater engagement. In general, reward learning processes on social media platforms are prominent in user behavior. A user’s social media activity boosts after a post, suggestive of reward anticipation, and users provide more social feedback to others after receiving feedback themselves. 

• TikTok sends many notifications to keep users informed about interactions and updates on the platform. Users are notified of event invitations, group and friend activity, tags, and mentions and prompted to reopen the app. Users can customize their TikTok notifications in their settings menu and control their delivery (e.g., push notifications, email, in-app notifications). 

TikTok does offer a daily time limit control. This feature allows users to set a time limit in 20-minute intervals, starting at 40 minutes and going up to 120 minutes. For users aged 13-17, however, it is set to 60 minutes by default. Once users reach their desired time limit, the screen will prompt them to input a passcode to return to scrolling on the app. The user will receive a reminder after they’ve used TikTok for the amount of time they chose. However, our research found that only 23% of TikTok users set limits on their use of TikTok. We also found that 38% of social media users who set limits report ignoring or overriding them frequently or almost always.(23)

While time spent on TikTok reduces available time for physical activity, Building H’s research did not find significant differences in the total amount of moderate or vigorous physical activity per week among heavy TikTok users, and light or moderate social media users.(24)

moderate negative influence

Like late-night TV viewing, social media usage after dark can negatively impact how long and how well you sleep. Using social media at night can negatively affect sleep in three ways:(25) 1) by offering a competitive alternative to sleep; 2) engaging the user’s attention and 3) through the bright, blue spectrum light of phone or computer screens that has been shown to suppress the production of melatonin, a hormone that signals the onset of the sleep cycle.(26)

TikTok techniques to engage users and both draw them to and keep them on the platform can affect sleep by engaging people in social media activity when they might otherwise be sleeping or winding down in preparation to sleep. Children sleeping with a smartphone (not specific to social media use) in their room reported 20 minutes less total sleep time and higher prevalence of perceived insufficient sleep than those without phones in the room.(27)

Using screens for 30 minutes after lights have been turned out has been associated with poor sleep quality.(28) In Building H’s consumer research, 69% of TikTok users and 76% of heavy TikTok users reported “always or almost always” or “frequently” using social media before bed.(29) Nearly a third of adolescents report screen use (which can encompass uses beyond social media) until midnight or later on a typical weekday.(30)

High social media use (not specific to TikTok) among youth has been associated with increased frequency of sleep disturbance,(31) late sleep onset(32) and trouble falling back asleep after nighttime awakening(33) and other sleep problems.(34) Nighttime notifications and compulsive smartphone checking have been associated with sleep problems in college students.(35) Our research found that 37% of TikTok users and 48% of heavy TikTok users reported either frequently or always or almost always waking up in the middle of the night and checking social media or their messages.(36)

TikTok does enable users to limit their daily use of the platform through a “quiet mode” that users can employ to mute notifications and to limit overall time spent on the app. Users can specify ranges of time when they want the app to be available and when they do not want the ability to access the app.(37) In addition, TikTok offers other time management features to help users understand their usage of the platform. As noted earlier, a minority of TikTok users utilize the limits, and many who do report often ignoring or overriding those.

TikTok might also influence sleep indirectly through its influences on physical activity and time spent outdoors, as both of those behaviors are positively correlated with better sleep.

In our research, we did not see significant differences between TikTok users, heavy TikTok users, and the general population regarding amount of sleep. Between 33-37% of all groups reported six (6) or fewer hours of sleep per night.(38)

Engaging Socially

neutral to slight positive influence

The influence of social media platforms on the social engagement of their users is complex because the platforms are evolving, research is continually emerging, and there is evidence of both positive and negative influences. These influences can vary significantly across individuals and any one individual can have both positive and negative experiences. As such, the scientific consensus is evolving with ongoing discussions on how to maximize benefits while minimizing harms.

TikTok enables users to engage, connect, and re-connect with people they might not have had the chance to in years past, to deepen weak tie relationships, and to find people they have things in common with via hashtags, groups, and other features. In addition to enabling posts and updates users share with their social networks, TikTok supports ‘group chats,’ where users can send videos and content to others with similar interests worldwide or nearby, and direct private messaging between and among users.

Building H’s research found that heavy users of TikTok users had somewhat higher levels of in-person social activity than others: 66% of heavy TikTok users reported having two or more social visits with people outside of their household per week, as compared with 42% of light social media users and 47% of moderate social media users.(39) Additional research has shown that teens who are “constantly online” are as likely to socialize with friends online as teens who are online less often.(40) Note that it is unclear whether use of social media leads to more in-person interaction or the reverse.

On the quality of connections, a recent study, which measured usage of online social systems and users' positive and negative experiences with social media, revealed that 15.4% of TikTok users reported experiencing a meaningful connection in the last 28 days; only 4.3% reported having personally witnessed or experienced something that affected them negatively.(41)

Building H’s research found that higher TikTok use did correlate with higher likelihood of loneliness. Fifty-six (56) percent of heavy TikTok users (2+ hours a day) reported being lonely, as compared to 35% of light and 40% of moderate social media users.(42)

Building H’s consumer research looked at social connectedness and how social media platforms increased connection with family, friends, and neighbors. Fifty-three (53) percent of TikTok users reported that their social media use made them feel more connected to family, 65% more connected with friends, and 47% more connected with neighbors.(43) Heavy TikTok users were even more likely to report greater connectedness: 56% reported feeling more connected to family, 65% more connected with friends, and 50% more connected with neighbors as a result of their social media use.(44) Additional research has shown that 80% of teens report that they feel more connected to what's going on in their friends’ lives as a result of social media use.(45)

In the Building H’s survey of social media users, participants were asked how the social media platform they use most frequently had influenced their relationships and social interactions in 13 different ways, including, for example, “meet new people,” “give emotional support to others,” and “feel less excluded.”(46) People who used TikTok the most reported that the platform had a slightly positive influence: on a scale of +3 to -3, the average score was 0.62 across all 13 questions. TikTok scored highest on “interact with people I know” (1.16) and “interact with people different from me” (0.91) and lowest on “create less conflict, adversity, or strain in my interactions with others” (0.36) and "meet new people" (0.37).(47)

Getting Outdoors

neutral influence

Social media platforms can both limit and encourage users to spend time outdoors. By browsing photos, videos, and geolocations of popular destinations, users can be inspired by others to get out and experience these places in the physical world. There is some research to suggest that social media (not specific to TikTok) is drawing new people to outdoor recreation areas.(48) The idea that social media has ruined many outdoor places by drawing new people to them is a familiar discussion in outdoor blogs,(49) which gives credence to the idea that social media platforms are drawing more people to the outdoors. Indeed, visits to national parks have increased significantly over the years that social media platforms have become popular.(50)

Social media, when consumed indoors, can be a competitive alternative to spending time outdoors. It offers the ability to connect with others conveniently, asynchronously and without needing to be together physically (and thus not needing to leave home). One study, which focused on rural youth in the US, showed an inverse relationship between screen time (in general, not specific to social media) and time spent outdoors.(51)

Building H’s consumer research found that 31% of heavy TikTok users reported using social media outdoors frequently. Eighteen (18%) of heavy TikTok users reported using social media outdoors rarely or never.(52)

In our research, we did not find a correlation between TikTok use and less time spent outdoors. In fact, 61% of heavy TikTok users reported spending one or more hours outdoors per day, as compared to only 49% of ‘light’ social media users.(53)
