Today’s Health Upgrade |
The new DHA study had mixed findings Covering your financial and identity blindside You achieved your goal. Why don’t you feel better? Sit and be healthier (the research that shows it’s possible)
|
On Our Radar Supplemental DHA Reaches Your Brain. But Then Memory Didn’t Change |
Fish oil’s brain-health promise rests on a simple idea: DHA is an important part of the brain, so getting more of it into the brain should help protect memory. |
Researchers had limited evidence about how much DHA reached the brain and what impact it had. A new two-year trial offered some new data. |
After two years, people taking DHA had far more of it in their blood and the fluid surrounding the brain. However, their memory, thinking scores, and brain scans were no better than those taking a placebo. |
Researchers examined participants between 55 and 80 who ate very little omega-3 and had at least one risk factor for dementia. Nearly half carried APOE4, the gene variant associated with a higher risk of Alzheimer’s. Participants took either 2 grams of DHA per day or a placebo. |
The DHA marker rose in the supplement group and dipped in the placebo group. Blood omega-3 levels increased from about 5 percent to 11 percent, so absorption wasn’t the problem. |
But the groups showed no difference in memory or other measures of thinking. Brain volume didn’t differ either. |
One explanation for disappointing omega-3 trials has been that too little DHA reaches the brain. In this study, researchers still found no cognitive benefit over two years. At the same time, it’s just one study, and more research is needed to better understand the relationships between supplemental DHA and cognition. |
This does not make fish oil useless. Omega-3s can lower triglycerides, with a couple of grams per day reducing levels by around 15 percent. They may also ease joint stiffness in people with rheumatoid arthritis and offer a modest benefit for mood. |
Eating fish a couple of times per week is associated with fewer cardiac deaths, although the clearest benefit from supplements appears in people who already have high triglycerides. |
So keep eating healthy fats and fatty fish. But if you’re taking a high-dose capsule as memory insurance, this study suggests there’s more for us to learn before we can feel confident that it helps. |
Together With Coveron The Blind Spot Most People Never Check |
Most threats to your health don't send a warning. Cholesterol creeps up without a symptom. Blood pressure climbs while you feel completely fine. |
That's why the smartest health habits aren't always about fixing things. They're about seeing things clearly. |
A blood panel shows you what's happening inside your body. A nutrition tracker turns "I eat pretty well" into food clarity. A blood pressure reading catches the stress you stopped noticing months ago. None of them fix anything on their own. They just remove the blind spot. |
If you can see your blind spots and prepare for them, you're far less likely to get blindsided. |
Most of us apply that logic to our bodies. But far too few apply it to threats beyond their control. |
In a classic 1980 study, psychologist Neil Weinstein asked college students to compare their odds of dozens of future life events with those of their classmates. |
For the bad events, people consistently rated themselves less likely than average. But everyone can't be below average. |
Scientists call it unrealistic optimism, and they've replicated it for decades. |
It's the same reason identity theft feels like something that happens to other people. It isn't. |
In a 2026 AARP survey, nearly 4 in 10 U.S. adults said they'd had money stolen or their personal information used fraudulently |
You don't need to panic. Not every data breach turns into theft. But a leak you don't know about is one you can't respond to. |
To protect yourself, freeze your credit at Equifax, Experian, and TransUnion (it's free and takes about 15 minutes). |
That is a foundational step. But a freeze is a lock, not a camera. It won't tell you when your Social Security number shows up on a dark web marketplace, when someone opens a line of credit, or when someone pulls money from your bank account. |
That's why we love Coveron. Like blood pressure for your money and identity, it offers a monitoring layer for everything you can't see: |
Dark web monitoring, 24/7, for your social security number, email addresses, and phone number |
Credit monitoring across all three bureaus, flagging new accounts, credit inquiries, and added signers |
Bank and credit card alerts for unexpected withdrawals, loan applications, and suspicious charges |
A dedicated case manager if something happens. |
Real financial protection: If a scammer does slip through, Coveron's insurance benefits cover eligible losses up to $2 million for identity theft recovery and up to $10,000 for online fraud. |
You set it up once, and it keeps watching. We think removing and protecting against unnecessary stressors is one of the healthier things you can do. |

Better Questions, Better Solutions You Hit the Number. Why Didn't It Feel Like Enough? |
You got the promotion, bought the house, or finally achieved the number on the scale you spent two years chasing. |
Then, you waited for the feeling everyone promised would follow. But it wasn’t anything like what you expected. |
Old question: Why don’t my accomplishments feel better? Better question: What did I want this goal to do for me, or how does it reflect the person I want to become? |
The first question almost always ends with you chasing a bigger target after you hit your goal, whether it’s more money, a higher title, or another ten pounds. The chase can seem insatiable, as if the feeling you want needs a larger dose. |
The second question sends you looking beyond the goal at what you’re trying to add to your life. |
Research suggests hitting a goal tends to lift how you feel when the goal feeds a deeper need. Money, status, and looks mostly don't. |
Scientists tracked people through their first years out of college, as they started building the lives they'd planned. Participants were measured on how much they valued seven goals: four intrinsic (close relationships, personal growth, community, health) and three extrinsic (money, fame, image). A year later, the scientists followed up to see who'd made progress and how they were doing. |
The people chasing money and image moved toward their targets about as reliably as the people chasing growth and connection. But the payoff was different. |
Progress on the intrinsic goals tracked with more life satisfaction, higher self-esteem, and better mood. |
Progress on money, fame, and image didn't track with any bump in well-being. If anything, it came with slightly more anxiety and physical stress. |
The researchers believe the results reflect three needs we all have: |
To feel our choices are our own To feel capable To feel connected to people who matter.
|
Growth, relationships, and health feed those needs directly. |
The results can't explain everyone or every outcome, and financial gain or fame can still make you happy. That’s not to say you shouldn’t chase those goals or that you won’t find joy when you get there. |
But goals with meaning are more likely to give you the feeling you desire when you reach the finish line. |
A separate analysis of more than 70,000 people across ages and cultures found the same pattern at scale, with one added insight: letting status goals become your purpose is associated with lower well-being. |
So look at the next goal on your list and ask the better question: What is it really for? |
If it’s not an intrinsic goal, you don't need to abandon it. But your best bet is to pair it with a goal built around growth or relationships, like reconnecting with an old friend or volunteering a few hours a month. That's the one that brings the emotional payoff and more joy, regardless of what happens with the others. |
Health The Heart Habit That Feels Like Sitting Still |
Most people treat the sauna as a post-training reward. But a long-running study suggests that using one regularly could do more than help sore muscles. |
Men who used a sauna four to seven times per week were 63% less likely to die suddenly from a heart problem than men who went once a week. Those who went two or three times still saw additional health benefits, though not as extreme. |
The study followed participants for nearly 21 years. They used traditional dry saunas heated to about 170°F. |
The most frequent sauna users also had roughly half the risk of dying from cardiovascular disease and a 40% lower risk of dying from any cause. |
And it’s not the first study to suggest that sauna can reduce certain health risks. Regular sauna use was linked to fewer strokes in a group that included men and women. And going four to seven times per week was associated with a 66% lower risk of dementia. |
Those numbers are impressive, but they don’t prove the sauna caused the difference. The frequent users may have had other healthy habits that helped protect them. And the study was small; we can see a connection, but that’s not enough to make definitive claims about what it can do for your health. |
We’re sharing it because many studies support the benefits of heat, and the idea isn’t far-fetched. |
Heat raises your heart rate, increases blood flow, and can temporarily lower blood pressure. Over time, regular sauna use may help blood vessels respond and relax more effectively. |
A sauna isn’t a substitute for exercise. But it does simulate similar responses to exercise. So if you enjoy it, there's a good reason to make it a regular part of your week. |
If you’re going to use a sauna, start with shorter sessions (think 10-15 minutes), drink water, avoid mixing it with alcohol, and stand up slowly when you’re done. If you’re pregnant or have a heart condition, check with your doctor first. The research can’t promise a longer life, but the sauna may be doing more than helping you unwind. |
If you have a sauna you like, tell us about it. We’re testing different options so we can recommend the best one for you. |

| | | | Take any of these tips from today’s email and put them into action: | 1. Fish Oil and Memory: 2-Year DHA Trial Finds No Benefit | High-dose DHA does not appear to protect memory. In a 2026 randomized trial, 2 g/day of DHA for 24 months reached the brain. However, it produced no difference from placebo in cognition or brain volume. Omega-3s still have health benefits, such as lower triglycerides, supporting heart health, and potentially helping with healthy joints and ligaments. | 2. Why Achieving Your Goals Doesn’t Feel Like You Expected | Achieving a goal tends to lift well-being only when the goal meets a core need for autonomy, competence, or connection. In a one-year post-college study, attaining intrinsic aspirations was linked to better psychological health, while attaining extrinsic ones was not and was linked to more ill-being. Goals that meet a need directly (think growth, close relationships, community, and health) are more likely to leave you feeling satisfied because they are more meaningful. | 3. Spending Time In a Sauna 4 to 7 Times a Week Linked to 63% Lower Cardiac Death | Frequent sauna use is strongly associated with better heart outcomes. Over a follow-up of nearly 21 years, those using a sauna 4to 7 times a week significantly reduced their risk of sudden cardiac death. The study was observational, so it cannot prove causation. This is likely because sauna mimics some of exercise's effects, like a higher heart rate and more blood flow, but it isn't a substitute for your workouts. |
