Stimulate Alertness and Wakefulness -
They reported their first alertness rating at the start of breakfast and then intermittently over the subsequent 3 hours. Specifically, when a participant slept longer than usual or woke up later than their usual time, they were more likely to show higher levels of alertness the next morning.
Higher levels of physical activity during the previous day were also associated with increased morning alertness.
Only physical activity levels during the 10 most active hours of the previous day were positively correlated with morning alertness levels. The researchers then examined the impact of the macronutrient composition of breakfast on morning alertness.
They provided calorie-matched standardized breakfasts of varying nutritional compositions, including high carbohydrate , high protein, and high fiber meals to each participant, which were consumed on different days.
Among the different standardized meals provided to the participants, consumption of a high carbohydrate breakfast was associated with higher levels of morning alertness than the reference meal.
In contrast, the high protein breakfast was linked to lower alertness levels than the reference meal. The researchers also examined how the changes in blood glucose sugar levels after the consumption of breakfast influenced morning alertness levels.
Independent of breakfast composition, a lower blood glycemic load , a measure of the impact of food intake on blood glucose levels, after breakfast was associated with greater morning alertness. Jeff Kahn , CEO and co-founder of energy and sleep tracker subscription app Rise Science, who was not involved in this study, commented on the findings, telling MNT that:.
While these factors explained the day-to-day differences in morning alertness within the same individual, the authors were also interested in factors that could explain why certain participants had higher average alertness levels than others.
The present study consisted of both twins and genetically unrelated adults. This allowed the researchers to examine the extent to which genetic factors could influence daily alertness levels in twins.
The researchers acknowledged that their study had a few limitations. For instance, the morning alertness levels in the study were based on self-reports and could be susceptible to bias. The study also did not account for differences in light exposure during the morning, a factor known to significantly enhance alertness.
The researchers further noted that all standardized breakfasts consisted of carbohydrates, protein, and fat and only varied in the levels of these macronutrients. They cautioned that these results should not be taken at face value and lead to the adoption of meals composed only of carbohydrates for breakfast.

Sleep duration and physical activity. Huberman provides us with science-supported tools for enhancing daily focus, productivity, creativity, regulated mood, physical strength, and endurance for brain and body health. From his work, we can learn new skills and habits to maximize morning alertness and sustain our flow throughout the day.
A maximized morning starts the night before, as sleep is the foundation of our daily cycle. Huberman sheds light on the importance of sleep hygiene for an optimal morning routine. He recommends aiming for hours of sleep each night to keep your metabolic, immune, and endocrine systems functioning properly.
With quality sleep, you are set up for success with your morning routine, and in turn, more likely to align your circadian rhythms for sleepiness throughout the night and alertness during the day. Light is key for setting our circadian clocks.
Sunlight first thing in the morning alerts our brain and body to begin the day and triggers a morning dopamine release for a positive mood effect. Morning exposure to sunlight also modulates the timing of our cortisol pulse, which acts as a wake-up signal, helps us to stay alert and focused throughout the day, and sets the timer for a melatonin release hours later.
As for the night before, we want to avoid this cortisol pulse by limiting light exposure in the evening or using blue light blocking glasses. Huberman suggests getting outside and viewing sunlight without sunglasses as soon as you can after waking, at least within the first hour for minutes.
And for those who live in cold climates or where morning light is not possible, Huberman recommends turning on all the lights in your home and using a LED light therapy lamp to simulate sunlight.
Do you reach for your favorite caffeine as soon as you wake up? The longer we are awake, the more adenosine builds up in our brain and body so we can feel sleepy at nighttime.
And while we sleep, adenosine levels lower so we can wake up rested and ready for the day. Caffeine first thing in the morning specifically blocks the actions of adenosine, making us feel more awake.
This is helpful for morning alertness, however, around 1 or 2pm, the caffeine has worn off and the adenosine has an even more powerful effect of making us feel sleepy. This delayed consumption of caffeine will prevent the afternoon crash and reduce the urge for another cup of coffee, as well as enhance your mood during the day and quality of sleep at night.
Huberman recommends starting with minute increments per day to push out your caffeine intake until you get into that optimal zone. Outside of an alarm, our bodies are alerted to wake up for the day by an increase in core body temperature. This rise in body temperature also signals that cortisol pulse, the wake-up signal that helps us stay alert during the day and times our melatonin release in the evening with a subsequent decrease in body temperature.
While we may think that cold exposure in the morning would lower our core body temperature, Huberman explains that the opposite is true: when the surface of the body is cold, the core temperature increases.
This exposure to cold water shocks our brain into wakefulness and releases both dopamine and epinephrine for an experience of pleasure and focus. And following cold exposure, the dopamine and epinephrine release doubles, amplifying the positive effects.
Huberman recommends several forms of cold exposure, an ice bath, cold plunge tub, or cold shower, for an optimal 11 minutes per week, spread over several days. During the cold exposure, Huberman suggests deep breathing to calm your body during an agitated state and in turn, raise your level of mental toughness so you can take on the day with a resiliency mindset.
While cold exposure is initially uncomfortable, the body will adapt to the practice overtime while reaping the amazing benefits on mood, health, and performance.

Stimulate Alertness and Wakefulness -
Amphetamine-like stimulants are known to increase wakefulness by blocking dopamine reuptake, by stimulating dopamine release, or by both mechanisms. Caffeine inhibits adenosinergic receptors, which in turn can produce activation via interaction with GABAergic and dopaminergic neurotransmission.
Nicotine enhances acetylcholine neurotransmission in the basal forebrain and dopamine release. The Centers for Disease Control and Prevention CDC cannot attest to the accuracy of a non-federal website.

Modafinil promotes wakefulness and alertness and may have some value in treating stimulant withdrawal and could be effective in decreasing drug craving and dependence. However, further research is needed. There is no safe level of drug use.
Modafinil affects everyone differently, but the most common side effects include:. Research into nootropics is still limited which means there is a lot of uncertainty about the side effects the drugs may cause if used on an ongoing basis.
It is recommended that these drugs are used only with a prescription from a medical practitioner to avoid any potential harms. Brand names: Ritalin®, Ritalin la®, Concerta®, Ritalin 10®, Dexamphetamine tablets®, Vyvanse®.
Ritalin was introduced during the s to treat chronic fatigue, depression, and psychosis associated with depression. It was used extensively in the s to treat ADHD and is now the most common psychotropic medication prescribed to children in the United States and Australia to treat restlessness, impulsive behaviour and inattentiveness.
This research showed changes in brain chemistry associated with risk-taking behaviour, sleep disruption and other undesirable effects such as weight loss. Methylphenidate affects everyone differently, but the most common side effects may include:.
Certain B vitamins, fish oil and herbal supplements such as Gingko biloba and extracts of Bacopa monnieri may offer a safer option to pharmaceutical drugs to enhance cognitive performance.
The benefits may not be as immediate but the effects are reportedly much longer lasting. However, the American Medical Association has advised that a number of products being advertised as nootropic supplements have not been examined in terms of safety and efficacy.
Modafinil and is a Schedule 4 substance that can only be prescribed by a doctor or dentist in the ordinary course of their professions. Methylphenidate is a Schedule 8 drug which means doctors must follow state and territory laws when prescribing it and must notify, or receive approval from, the appropriate health authority.
Using modafinil or methylphenidate without a prescription from a doctor, or selling or giving them to someone else, is illegal. There are also laws against forging or altering a prescription or making false representation to obtain pharmaceuticals or a prescription for them.

Many people struggle with morning alertness, but a new study demonstrates that awaking refreshed each day is not just something a lucky few are born with. Scientists at the University of California, Berkeley, have discovered that you can wake up each morning without feeling sluggish by paying attention to three key factors: sleep, exercise and breakfast. The findings come from a detailed analysis of the behavior of people who, over a two-week period, were given a variety of breakfast meals; wore wristwatches to record their physical activity and sleep quantity, quality, timing and regularity; kept diaries of their food intake; and recorded their alertness levels from the moment they woke up and throughout the day.
