Another week, another reason to prioritize your sleep. Seriously, it’s important.

Sunscreen and water safety are the obvious beach health priorities, but there’s something else to think about before you dive in: rashes and infections. The one getting the most attention lately is Vibrio vulnificus, a bacterium found in warm coastal saltwater that's been expanding north as ocean temperatures rise and can make its way into your body via open wounds or cuts. You can get staph infections in the same way, but the bacterium is actually more common at the beach—found in over half of seawater and sand samples in one study. For both, the prevention is the same: Wear shoes on rocky sand, clean any cuts immediately, and shower right after swimming. If you’re immunocompromised, diabetic, or have liver disease, you should be especially careful about ocean exposure with open skin.
Another skin issue is seabather's eruption, which is a bumpy rash caused by microscopic jellyfish larvae trapped under your swimsuit (ew). You can minimize this one by changing out of your suit promptly and drying it on high heat.
And in terms of infections, we’ve got two more to watch out for. Norovirus, which spreads through sewage-contaminated ocean water, is mostly a risk if you're swallowing water while swimming (so it’s worth keeping an eye on kids especially). The second is Cutaneous larva migrans, a parasitic skin infection, which is easy enough to sidestep by wearing sandals or a towel on the sand rather than walking barefoot.

Unlike most supplements, fish oil seems to have a (positive) consensus. Most of us get plenty of omega-6 fatty acids and not enough omega-3s, which can drive inflammation throughout the body. Fish oil supplements can help correct that ratio—and because omega-3s touch so many systems at once, the benefits tend to be broad. It's considered especially worthwhile for women who are pregnant or postpartum, over 45, navigating perimenopause, have cardiovascular risk factors, or are dealing with chronic inflammation and/or mood instability. Here’s what you should know (and remember to check in with your doc to make sure you’d benefit).
-
Fish oil provides cardiometabolic and anti-inflammatory benefits that make it one of the most commonly consumed supplements in the country (for legitimate, science-backed reasons.
- EPA and DHA (here’s a vegan option) play a real role in cognitive function, focus, and mood regulation.
- The anti-inflammatory properties of omega-3s can support the gut lining, and there's emerging research around a potential connection between omega-3s and the microbiome.
- EPA and DHA's anti-inflammatory effects can support skin-barrier function over time. Just don't expect immediately glowing skin.
- Some formulations, particularly those high in DHA, may raise LDL cholesterol. If that’s a concern, make sure to chat with your doctor before starting.
- Both capsules and liquid are equivalent in efficacy when they deliver comparable amounts of EPA and DHA. But capsules usually win on taste.
