What is an Institutional Review Board (IRB)?

3 minutes

An IRB is a review board designed to protect the rights and well-being of research participants. It acts as a system of checks and balances for any research involving people. 

Welcome to the next article in our Research 101 series! We're excited to share with you some important information about Institutional Review Boards (IRBs), which are essential to the research process. 

If you’ve ever thought about participating in research, you may have had some questions about how the research could affect you. You may have wondered:

  • What are the risks and benefits?
  • How will my data be used?
  • How do I know I am safe?

Researchers care a lot about providing a safe and ethical study experience. One way we do this is by submitting our research protocols to an Institutional Review Board (IRB). 

What is an IRB?

An IRB is a review board designed to protect the rights and well-being of research participants. It acts as a system of checks and balances for any research involving people. 

IRBs work to ensure the following: 

  • Research studies have scientific merit and purpose 
  • The activities involved in the research are ethical 
  • All regulatory requirements are followed 

Every IRB has at least five members with different backgrounds. The members may have training in scientific areas, have expertise and training in non-scientific areas, or be members of the community who may represent the people who would participate in the research study.

IRBs are the gatekeepers when it comes to being able to conduct research involving human beings. Without IRB approval, researchers are unable to conduct their research.  

History of the Institutional Review Board (IRB)

The idea of an Institutional Review Board (IRB) began in 1974 when President Richard Nixon signed into law the National Research Act. The act led to the creation of the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. Events such as the Tuskegee Trials and the Willowbrook Experiments, where research was conducted in an improper manner, proved there was a need for unbiased oversight. 

This commission was in charge of identifying the principles that should underlie the conduct of research. They also created guidelines to make sure research is carried out following those principles. In 1979, the commission published "Ethical Principles and Guidelines for the Protection of Human Subjects of Research," also known as the Belmont Report

The Belmont Report is made up of three core principles:

  1. Respect for Persons - Giving people the right and capacity to make their own decisions.
  2. Beneficence - Minimizing potential harms and maximizing benefits 
  3. Justice - Distributing benefits and risks fairly 

IRBs were founded on these three basic principles which are still referenced when reviewing research proposals. 

What does the IRB review? 

The people who make up the committee carefully consider the following:

  • Are procedures in place to reduce any harm or risks to the participants? 
  • Do the benefits outweigh the associated risks?
  • Is the selection of participants equitable and fair?
  • Are potential participants able and willing to give informed consent?
  • Will a participant's consent (or permission) be properly documented? 
  • Do the researchers have a plan for monitoring the quality of the study data to ensure participant safety?
  • Are there adequate procedures in place to protect the privacy of participants? 
  • Will the researchers be able to maintain the privacy of study participants?
  • Are there protections in place for vulnerable populations? 
  • Does the research meet all regulatory requirements? 

Evidation Studies & IRB Oversight 

Research conducted by the Evidation Studies (formerly Achievement Studies) team often requires approval from an IRB. The decision to have a study approved by an IRB is based on the design of the study and what the researchers will use the results for.

At Evidation Studies, we have a dedicated team of researchers who help oversee the protection of our study participants every step of the way. Even when IRB approval is not required. 

Our study participants can be confident that we’re committed to their safety and that our studies are conducted according to the highest standards.

5 Summer Self-Care Tips to Boost Your Mood

5 minutes

Self-care is important all year long, and the warm days of summer provide great opportunities. Check out our tips on improving wellbeing during the summer months.

Nearly 1 in 5 US adults live with some form of mental illness. And the numbers are rising.

Mental illness is a common issue among Americans, but it’s something we can work on by practicing self-care all year round. And during the months of summer, there are a variety of self-care methods we can take part in to boost our mood while enjoying the warm weather.

In today’s article, we’ll be sharing 5 summer self-care tips to boost your mood and mind, all while embracing the sun. Keep reading to learn more. 

Get some sun

Many people struggle with what's known as seasonal depressive disorder (SAD). SAD relates to the change in seasons, many people experience symptoms in the fall and later in the winter months.

And most people affected by SAD live at latitudes far south and far north of the equator where there’s much less sunlight during the fall and winter months.

But why?

The reason for this could be that in the darker months of winter and fall people are exposed to less sunlight. The skin produces Vitamin D when it’s exposed to the sun, and Vitamin D can help increase serotonin activity.

What’s serotonin?

And what does serotonin have to do with our mood?

Serotonin is a neurotransmitter (a chemical messenger) that carries messages between your brain and throughout the body. It has several roles, including influencing our memory, learning, and happiness. 

Low levels of serotonin may cause depression.

Getting out in the sun may be a great way to not only get more Vitamin D, but it may also help increase the level of serotonin activity within us. Potentially improving our overall mood. 

While getting sun is important, it’s vital to protect yourself from getting a sunburn or heat stroke.

It’s best to protect your skin with sunscreen and reapply every so often throughout the day. Reflective clothing is another great way to keep your skin safe in the sun.

Keeping cool is also important, as spending long amounts of time exposed to the sun could result in heat stroke. Try taking breaks from the sun in the shade and do your best to not over-exert yourself. 

Exercise outdoors

In many places, one of the great things that summer has to offer is the ability to exercise outdoors.

Physical activity can:

  • Help improve brain health - regular exercise may help improve cognitive function and sleep, and it may reduce depression and anxiety risk and overall improve our quality of life.
  • Help manage weight - physical activity can help burn calories, build muscle, and decrease total body fat. This could result in better self-esteem and overall a more positive mood.
  • Help improve our ability to do day-to-day tasks - when we improve our overall health, day-to-day tasks become easier. This can lead to a better quality of life and can greatly improve mood and well-being.

When compared to indoor activity, outdoor activity seems to have a greater impact on improving mental health. Studies suggest spending time in natural environments may have a positive impact on well-being.

The combination of mental health benefits from spending time outdoors as well as exercise is something worth taking advantage of.

So instead of going for a run at the gym, take a jog around your neighborhood. Or, try getting involved with some outdoor sports.

Relax outdoors

In one review of research, there’s evidence that spending time outdoors with nature can increase happiness and positive social interactions. It may even help bring a sense of purpose and meaning to our lives.

Combining your favorite way of relaxing with spending time outdoors might be an effective way to maximize your self-care this summer.

Different forms of relaxation may have different effects, but relaxation can help us:

  • Reduce stress
  • Improve sleep quality
  • Improve mood and focus
  • Reduce anger and frustration
  • Reduce muscle tension and chronic pain 

So, what are some of the different ways we can relax outdoors?

It depends on what you like to do, but a few ideas might include:

  • Yoga
  • Reading
  • Meditating
  • Breathing techniques 

We encourage you to get outside and take some time to relax and unwind during the summer months!

Take some time off

The summer months are some of the best times to take a break from work.

Whether you decide to go on a vacation outside the country or enjoy the weather in your local area. It’s important to take time off to destress, and physically and mentally recharge.

Some benefits of taking a vacation from work might include:

  • Lower stress
  • Improved mental health
  • Improvement in productivity

Overall, taking time off is important. And summer presents an opportunity for all of us to enjoy a break from work while embracing the warm weather.

Explore nature

As discussed earlier, spending time outdoors may help improve our well-being and happiness.

And exposure to sunlight could help increase the levels of serotonin in the body.

But how does exploring nature help?

Just as completing a workout can help us develop confidence, exploring nature may have the same effect. 

You can try taking on a difficult hiking trail, or exploring a new area while paddling. Spending time outdoors and conquering a challenging task can increase your confidence and overall self-belief. 

Closing thoughts - 5 Summer Self-Care Tips to Boost Your Mood 

With such a variety of options, summertime may be one of the best times to practice self-care and boost your mood. 

From getting your summer self-care essentials like sunscreen to relaxing outdoors by meditating or reading, there are many options when it comes to self-care in the summer.

And as more research comes to the forefront, we'll have a better understanding of how the sun and nature affect our moods.

Make sure to share this with a friend or family member who could use some self-care tips to boost their mood during the summer!

There are a variety of different activities you can take part in while out in the water.

Whether you enjoy kayaking, canoeing with a friend, or water sports. All activities are a great way to get some aerobic exercise and enjoy the water and weather.

Kayaking and canoeing work many muscles in the body. They engage upper body muscles, legs, and even core muscles. This may result in an increase in muscle mass and strength and an improved ability to balance.

There’s an endless amount of water sports to try. From wakeboarding to water polo, participating in these activities can help improve mental and physical strength and increase confidence.


During summer, the weather is warm enough to enjoy the water and embrace nature. Although, we recommend protecting yourself with sunscreen and keeping cool by staying in the shade when you can, and drinking lots of water.

So, whether you decide to take up a new hobby like wakeboarding, or try out a new trail in your local area, it’s up to you to decide what outdoor summer activity you want to take part in.
