31 wellness tips for healthy & happy living

Here are 31 tips to live a healthier, happier lifestyle—all simple, easy things that can be seamlessly incorporated into your daily life:

1. Drink a glass of water first thing in the morning

Coffee’s great too, but it’s best to start your day by re-hydrating with a full glass of water. Hydrating first thing in the morning helps to aid digestion, enhance skin health and boost energy.

2. Take the stairs

Taking the stairs instead of the elevator is a simple way to get a little more physical activity in your daily life. It also strengthens and tones your legs and core while you’re at it!

3. Make half your plate veggies

A simple hack for healthy eating (and portion control) is to make half your plate veggies at each meal. The veggies pack in essential vitamins, minerals and other phytonutrients important for health and longevity. And, because they’re rich in fiber, they help to aid digestion (aka keep you regular!) and keep you feeling full longer.

4. Get a fitness tracker + track your steps

Using a fitness tracker (like a Fitbit or Apple Watch) to track your steps is an easy way to make sure you’re getting enough physical activity each day. We aim for 10,000 steps daily, which has significant physical and mental health benefits. A fitness tracker will also remind you to get 250 steps each hour (another important measure of health—see tip #9!). Here are our favorite fitness tracker smartwatches of 2021.

5. Switch to non-toxic household cleaning products

Conventional household cleaning products are full of harmful chemical ingredients that are not good for our health (or the health of our kids or pets!). Switching to healthier alternatives is a simple way to reduce your exposure to environmental toxins in your home. See our Healthy Cleaning Guide for a complete list of recommendations, and what to look for when choosing safer household cleaning products.

6. Use non-toxic skincare + personal care products

Similar to cleaning products, conventional skincare and personal care products are formulated with toxic ingredients we should not regularly let absorb into our body’s largest organ. Reduce the toxic burden on your body by switching to non-toxic personal care and beauty products (see our specific recommendations on deodorant, sunscreen, and green beauty products).

7. Take a probiotic daily

Maintaining a healthy gut has significant impacts on digestion, skin health, immunity, mental health and more. Taking a daily probiotic with a glass of water each morning is one of the simplest things you can do to boost your gut health (which, in turn, boosts overall health in many ways too). Learn more about the health benefits of probiotics (and all the ways to get them in your diet), and shop our favorite probiotic supplement here.

8. Eat real food

Aim to eat real food that’s made of whole food ingredients you would have in your own kitchen pantry, or that your grandmother would recognize. (Yup, this rules out most packaged food, sorry!) This is a little different than suggesting you eat only “health foods” (many of which are increasingly processed!). “Real food” includes unprocessed foods like an apple, a cucumber, soybeans or a steak, as well as foods loosely processed from one (or few) real-food ingredients, like butter, olive oil, yogurt, tofu, etc. In other words, aim for foods that could be reasonably made in your own kitchen and avoid foods that can only be made in a lab.

9. Stand up every 30 minutes while working

Reduce the harmful effects of sitting (like at your desk job) by standing up and moving around for a minute or two every half hour.

10. Get sunlight every day

Vitamin D is one of the most important nutrients for overall health, and sunlight is one of our best sources of it. Aim to get at least 30 minutes of sunlight each day—preferably in the afternoon, and without sunscreen (read more about that here). Not much sunlight in the winter where you live? It might be worth supplementing with a vitamin D supplement and/or other food sources of this essential nutrient.

11. Fill your home with houseplants

Houseplants help to cleanse your indoor air (sadly, it probably needs it!), they’re pretty, and research even shows they improve mood, creativity and problem solving!

12. Sweat every day

Aim to sweat in some way each day—whether that’s via running, biking, dancing, hot yoga, or any other physical activity you enjoy. See our Fitness Guide for more workout ideas, as well as tips and tricks for building regular physical activity into your daily life and a downloadable fitness planner you can use to outline your own custom fitness plan to stay on track.

13. Have a daily green smoothie

Green smoothies as a snack or simple, on-the-go breakfast are an easy way to get your greens in each day. Check out our curated list of healthy (veggie-packed!) smoothie recipes for our favorite starter green smoothie recipe ideas.

14. Work hard + be kind

Enough said!

15. Cultivate a positive mindset

“The only difference between a good day and a bad day is your attitude.” It’s true—mindset is everything! Cultivate a positive mindset by recognizing negative thought patterns and countering them with positive thoughts or affirmations. Here are more mindset resources for positive thinking.

16. Get enough sleep

Most adults need 7-9 hours of sleep each night. But in addition to quantity, quality of sleep matters too! Follow our tips on getting quality sleep—things like keeping your bedroom cool at night, avoiding blue light after dark, and more.

17. Start your day with a healthy morning routine

Start each day with fulfilling activities that set the tone for how you want to feel—whether that’s inspired, relaxed, productive, or something else. 😄 Check out our list of ideas for starting a healthy morning routine to start your day right!

18. Eat the rainbow

Aim to eat all the colors of the rainbow each day. (Natural colors only, no Skittles!) Download our free fillable/printable Eat the Rainbow daily & weekly tracker to help keep track.

19. Floss your teeth

Floss your teeth daily for good dental health and overall health. Not only does flossing daily protect your teeth and gums, but good dental health is also important for immunity and heart health.

20. Spend time alone

Spending regular time alone helps to get to know and stay in touch with yourself (we’re all constantly growing and changing!). Alone time is an opportunity to check in with how you’re doing and what you want, so you can live your most intentional life. Some people enjoying hiking, going for a walk or run, meditating, or even sunbathing as a healthy source of alone time. ☀️

21. Do things you enjoy

This often gets overlooked as an essential element of healthy living—doing things each day that you enjoy! Whether that’s exercise, baking, crafting, reading a book or watching TV, reserve time each day to spend doing activities you personally enjoy.

22. Choose organic foods when possible

There are a gazillion health, environmental and social reasons to choose organic foods, so we’ll let that more detailed post linked do the talking and just remind you to choose organic foods whenever possible. They better for your health, the environment, and the farmworkers growing your food.

23. A teaspoon of apple cider vinegar keeps the doctor away

Apple cider vinegar cures everything (well… almost everything!). A teaspoon of apple cider vinegar in a glass of water helps aid digestion, relieve bloat, boost immunity, regulate blood sugar levels and more. We recommend organic, raw, unfiltered apple cider vinegar.

24. Smile often

Smiling boosts your physical and mental health (it’s true!), so find ways to smile as often as you can throughout the day.

25. Work on overcoming your fears

Fears hold us back and keep us from living life as our best self. Acknowledge your fears and take steps to overcome them. (One example of this is overcoming the fear of public speaking to open new doors in your career and personal life.)

26. Use a yoga ball as a desk chair

Save your back/shoulders/neck and strengthen your core by using a yoga ball as a desk chair.

27. Manage stress with self-care activities

Chronic stress is detrimental to both your physical and mental health. Get to know your stress triggers (the things that cause stress for you, either quickly or in the long-term) as well as your stress releases (the things that can help calm you when you’re stressed) so you can proactively cope with stress and maintain healthy levels.

28. Intermittent fasting can promote weight loss

We’re not really into dieting (restrictions are no fun!), but intermittent fasting is more of an eating pattern than a diet. It has several notable health benefits for reducing inflammation and contributing to longevity, and can help speed metabolism to promote weight loss.

29. Drink a glass of water after every alcoholic beverage

Nope, we’re not going to tell you to refrain from alcohol (though you certainly can if you want!). Drinking alcohol in moderation can be part of “healthy” lifestyle if done in a responsible manner. A glass of water after every alcoholic beverage helps to detoxify the alcohol from your body, as well as slow your alcohol consumption and keep you hydrated (a key factor in hangover prevention!).

30. Practice gratitude

Practice gratitude each day—this could be when you wake up, before bed, or during your lunch break at work. Here are our favorite tips for finding more gratitude in your daily life, plus a rundown of the physical and mental health benefits of practicing gratitude regularly.

31. A walk around the block is better than no walk at all

When it comes to a healthy lifestyle, doing just a little bit is better than doing nothing at all. If you want to go on a walk but don’t have time for your usual hour-long walk, take a short walk around the block. A 5-minute walk is better than no walk at all!

Fish Oil: Health Benefits, Uses, & Safety

Many of the health benefits of fish oil can be attributed to the presence of omega-3 essential fatty acids like docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), according to the USDA National Nutrient Database. Other useful essential fatty acids in fish oil include alpha-linolenic acid or ALA and gamma-linolenic acid or GLA. [1]

Here is a brief on omega-3 fatty acids: There are three types of omega-3 fatty acids, namely alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). All three are important for the body.

A few of these health benefits include its ability to aid in weight loss and improve the skin. It has also shown positive implications in reducing the risk of heart disease, high cholesterol, mental health disorders, and inflammation, as well as others.

There are various types of fish that are good sources of oil; they include mackerel, lake trout, herring, sardines, swordfish, oysters, albacore tuna, bluefin tuna, yellowfin tuna, turbot, pilchards, anchovies, and salmon. The quality of fish oil greatly depends on the type of fish from which the oil is retrieved.

Health Benefits of Fish Oil

Fish oil has a positive impact on most healthy adults, as it helps in weight loss, skincare, vision improvement, and other health issues.

Boosts Heart Health

According to the American Heart Association (AHA), clinical trials have shown that foods containing omega-3s are effective in reducing the incidence of cardiovascular diseases (CVD). Fish oil is a great source of omega-3 and therefore, may help individuals reduce the risk of heart diseases and heart arrhythmias. It also contributes to lowering elevated levels of LDL cholesterol (bad) and increases the level of HDL cholesterol (good). Omega 3 containing fish oil helps prevent the accumulation of triglycerides and also reduces the level of excess triglycerides. Preliminary research has shown that fish oil’s healthy components can be used to reduce the risk of atherosclerosis in coronary patients. Thus, regular usage of this oil may help avoid sudden cardiac death. As per the American Heart Association, these preliminary findings still need to be confirmed by further detailed research. [3]

Weight Loss

Anti-obesity research conducted by the University of South Australia has shown that combining fish oil with exercise is more beneficial in reducing obesity than either one alone. Volunteers who were given fish oil in their diet and exercised showed greater weight loss as compared to those who did not regularly consume it and exercised. Fish oil contains omega-3 fatty acids, which help to promote weight loss, so a combination of physical workout and intake of this oil helps in reducing body fat significantly faster.

Improves Immunity

It is thought that regular consumption of fish oil may aid in boosting your immune system, thereby enabling you to resist the occurrence of common ailments, such as cold, cough, and flu. The omega-3 fatty acids present in fish oil are thought to bolster the immune system by affecting the activity and amount of cytokines and eicosanoids present in our body. Some preliminary researchers published in the journal Animal Science have also studied the effect of bovine consuming fish and fish oil on their immune systems. They found that fish oil aided in the growth of the animals. Similar research conducted on mice at Taichung Veterans General Hospital in Taiwan also showed positive results.

Reduces Inflammation

Fish oil may be an effective method in helping to reduce inflammation in the blood and tissues. Ideally, it is best to consume actual omega-3 containing fish products to reap all of the beneficial nutrient interactions. Fish oil is thought by some suffering from gastrointestinal disorders–such as Celiac disease, short bowel syndrome, and inflammatory bowel disease (IBD) including Crohn’s Disease and ulcerative colitis–to be effective in reducing inflammation.

Other inflammatory states including arthritis, rheumatism, Raynaud’s symptoms, may also benefit from this oil. It may help in reducing the need for large dosages of NSAIDs (non-steroidal anti-inflammatory drugs). The Royal Adelaide Hospital and the University of Newcastle, located in Australia, have reported that fish oil has shown positive effects in treating the symptoms of arthritis.

While some research shows that regular consumption of fish oil supplements, tablets, pills, and capsules may be helpful to those who suffer from chronic inflammatory diseases, the jury is still out and more research is needed to confirm the benefits.

May Relieve Depression & Anxiety

Due to the presence of omega-3 fatty acids, fish oil has been promoted for relieving depression, sadness, anxiety, restlessness, mental fatigue, stress, and low libido. Countries where fish is frequently eaten, have a lower incidence of depression. Multiple preliminary studies have shown Omega-3s as a promising natural solution for mood disorders; however, more research is underway to confirm these beneficial effects.

Similarly, research conducted on prisoners has shown that when prisoners were given seafood containing a higher amount of omega-3 fatty acids, there was a significant drop in the homicide rate and the frequency of violence. Findings of another research study suggest that fish consumption may be beneficial for women’s mental health and reduces the risk of developing depression in women. While a clear link can’t yet be established given the multiple compounds in fish, it is a good basis for suggesting that increasing omega-3 content may be beneficial for this population.

May Reduce Risk & Progression of Neurodegenerative Disease

Research conducted at Louisiana State University has shown that fatty acids are connected to reducing the risk and slowing the progression of Alzheimer’s disease. Since fish oil is one of the best sources of essential fatty acids, including EPA and DHA, these may be a boon to those suffering. More research conducted at the University of California in Los Angeles validates the usefulness of fish oil as a possible remedy for the disease. The Alzheimer’s Association recommends consuming fish containing a higher content of omega-3 fatty acids to patients, as it may act as a defense against Alzheimer’s disease and dementia.

Reduction in ADHD Symptoms

Fish oil may have the potential to reduce the symptoms of Attention Deficit Hyperactivity Disorder (ADHD) due to its high concentration of fatty acids. For children suffering from hyperactivity, dyslexia, short attention span, low concentration, or learning disorders, fish oil may be a part of the solution.

Preliminary research conducted at the University of South Australia and CSIRO has shown that when children suffering from ADHD were given doses of fish oil and evening primrose capsules for 15 weeks, they showed significant improvements in their behavior. More research is in the works to look more closely at these potential benefits.

Furthermore, it is believed that fish oil is useful in the normal development of the brain, along with helping your child concentrate on their studies. It has also been found that when pregnant women are given regular doses of fish oil, their toddlers display enhanced hand-eye coordination.

Skin Care

Fish oil is great for improving the condition of dry skin by making it look shiny and vibrant. It has been found by some to be useful in treating various skin problems such as eczema, psoriasis, itching, skin redness, and rashes. In terms of psoriasis, the EPA present in fish oil restricts the growth of pro-inflammatory agents by producing arachidonic acid.

Fish oil can also be applied topically to get relief from psoriasis; however, many find that it has a limited positive effect. Intravenous administration of fish oil, however, has been shown more effective. It is also claimed by some people that the oil helps in preventing sunburn but the research behind that claim is not verified.

Treats Acne

Fish oil is thought to be a topical acne treatment. EPA present in the oil is known to inhibit androgen formation, which can affect the formation of sebum in the hair follicles, leading to acne.

Prevents Ulcers

The presence of EPA and DHA in fish oil may have some benefit in the case of ulcers caused by Nonsteroidal anti-inflammatory drugs (NSAIDs).

Supports Healthy Pregnancy

Fish oil is beneficial for pregnant women as the DHA present in it helps in the development of the eyes and brain of the baby. Lack of seafood – and thus omega-3s were linked with premature births, low birth weight, and miscarriages. Research conducted in Denmark, which involved 8,729 pregnant women, concluded that a diet with low amounts of fish resulted in a higher risk of premature or preterm babies.

It is also believed that women who do not have a sufficient intake of EPA and DHA in their diet suffer from depression after childbirth. Thus, it may be beneficial to consume fish oil either by consuming fish or taking fish oil supplements, tablets, capsules, or pills during pregnancy for the overall development of the child and the well-being of the mother. However, fish oil obtained from the liver of the fish, for example – cod liver oil – should not be consumed during pregnancy as cod liver oil is high in retinol and vitamin A, which are usually known to cause birth defects. If you are pregnant or trying to become pregnant, be sure to discuss options for getting fish oil with your OBGYN or primary doctor.

Improves Fertility

Fish oils rich in omega 3 fatty acids may help improve fertility and cell division in s***m. Preliminary research conducted on animals has shown that when males are fed a diet containing fish oil, the quality of the s***m is enhanced. After ej*******on, the s***m has increased survival against lipid peroxidative attacks in the female ge***al tract, thereby increasing the chances of conception. On the other hand, similar animal studies have shown inhibition in the synthesis of prostaglandin E and prostaglandin F, which are produced in large quantities by human seminal vesicles. The research, however, found no impact on the count and mobility of s***m. More research is needed to clarify these results; however, given its slew of other positive benefits, it is still a benefit to consuming by most people.

Hair Care

Fish oil is thought to help maintain good hair shine and luster because omega-3 has growth stimulating properties and provides nourishment to the follicles. A good supply of protein is also necessary for hair growth, and since most fish varieties are rich in protein, eating fish provides both of these hair health benefits.

Many people also like to feed fish oil to their pets, especially dogs and cats, as it promotes shiny and smooth hair.

Fish Oil and Lou Gehrig’s Disease

Fish oil is rich in omega-3 fatty acids, as mentioned. Recent research suggests that intake of a diet rich in omega-3 fatty acids may reduce or delay the onset of Amyotrophic lateral sclerosis (ALS) also known as Lou Gehrig’s disease.

Fish Oil Side Effects

Even though fish oil has many benefits, excessive intake may cause allergy and side-effects. People who are allergic to seafood or fish, in particular, will experience effects like hives and swelling of face, lips, tongue, or throat. Consuming seafood or fish is not advised if you have a known allergy.

In the case of excess intake, one may also experience bad breath, stomach upset, loose stools, belching, nausea, or even more serious effects. Avoid consumption if allergic to fish. The American Heart Association recommends at least two servings of fatty fish weekly.

Let us look at some of the side-effects in detail:

Children: Excessive intake of fish oil by children may lead to allergic reactions like itchiness, sneezing, or a dry cough.
Pregnant Women: Even though fish oil has many benefits for pregnant women, the mercury content found in certain seafood can be harmful to the memory, hearing abilities, cognitive skills, and vision of the baby.

Caution on Fish Oil Amount

An excessive dosage of fish oil can have adverse allergies and side effects on the body. Furthermore, fish oil can be problematic if you have certain conditions, so it is necessary to check with your doctor before consuming fish oil supplements. While consuming fish oil directly from fish is one thing, taking it in the form of concentrated dietary supplements like liquid, tablet, capsule, pill, or soft gels may pose an issue. Dietary supplements in the United States are not regulated by the government, so choosing a safe option is important.

Should We Replace Vegetable Oils with Fish Oil?

The short answer: not necessarily. There are many websites which advise people to stop eating vegetable oils and switch to fish oil to increase their intake of omega-3 fatty acids. Fish oil is a good source of omega-3 essential fatty acids and should be consumed, but that doesn’t necessarily mean that one should completely replace vegetable oils with fish oil.

Vegetable sources, including flaxseed oil, soybean oil, h**p oil, canola oil, walnut oil, rapeseed, perilla, chia, and tofu are rich in ALA. The human body can convert ALA to DHA and EPA, though there are certain limitations to this conversion. Additionally, eating a varied, healthy diet full of many different foods is most beneficial for health, as different foods provide robust nutrition that the body needs to function optimally.

How much fish oil is safe to consume?

Fish oil can be consumed in various ways such as capsules or can be included in daily meals. Research suggests that the dosage should not exceed three fish oil capsules per day. 1000mg of fish oil contains approximately 300mg omega-3 fatty acids. A daily intake of 3000mg or less is commonly thought of as being safe for the general population. Pregnant and lactating women can consume approximately 3200 mg per day.

Fish Oil Purity

When purchasing fish oil, pay attention to quality. It is obtained from almost all fishes including – freshwater, farmed, ocean, deep sea, and shallow sea fish. All of these fish can be contaminated with toxic compounds such as mercury, arsenic, lead, forms of calcium, furans, dioxins, PCBs, and methylmercury, and can negatively affect the human body. Therefore, the fish oil used must be pure. Many companies sell ultra refined or distilled fish oil, but you should always check if the standards have been followed and research on the company or the product before adding it to your diet.

While fish oil has plenty of beneficial qualities, there is a lot of hype around its possible applications, and not all of them are accurate, so be wary when reading literature on this useful oil. Fish oil manufacturers have attempted to market it as a remedy for almost anything. We suggest that readers educate themselves fully before making an informed decision, rather than getting affected by both negative and positive propaganda about the beneficial applications of fish oil.

Fish Oil and Vitamins

Vitamin A and Vitamin D: Fish oil, especially the types obtained from fish livers like cod liver oil is a rich source of vitamin A and vitamin D. However, excessive dosage of cod liver oil can lead to vitamin toxicity, the accumulation of excessive vitamins in the body, which can cause serious side effects.

Vitamin E: Fish oil undergoes oxidation and can become rancid, leading to the formation of free radicals. The addition of antioxidants such as vitamin E to the oil can help prevent the formation of these free radicals.

An excessive dosage of fish oil is thought to lead to decreased levels of vitamin E in the human body. This is another reason why adequate intake–but not excess–should be achieved.
