We’re sure at some stage you ran about in the ocean scaring younger family members with those weird plants you found in the sea
Turns out they a different use than just causing nightmares for the kids. They’re not only edible, but pretty healthy too. Seaweed is low in kilojoules, high in nutrients, and surprisingly delicious, says Rousell. Your thyroid gland, the master regulator of how many kilojoules you burn throughout the day, uses the iodine in seaweed to produce two hormones, T3 and T4. Men’s iodine consumption has been declining since the 1970s, so your body might actually need those seaweed snacks. Reach for them instead of potato chips.
Life in the office can get hard crunching all those numbers while staring at a screen
If you’re stuck staring at a computer screen all day, you need to regularly rest your eyes. The American Opto-metric Association recommends the 20-20-20 rule: first set your phone to buzz every 20 minutes. When the alarm rings, focus on something that’s about 20 feet away for 20 seconds; this will help your eye muscles relax. And you’ll have an excuse for staring mindlessly into the distance. That’s not daydreaming! It’s preventative medicine.
So we’ve all heard or read different pieces of the benefits and risks of marijuana. But how safe is it really?
Thankfully, marijuana smoke doesn’t appear to significantly increase your risk of lung cancer. But a vapourizer is a smart move. In one study, habitual marijuana smokers who were prone to coughing saw heir respiratory symptoms improve 73 percent after they switched to a vapourizer. They could also puff more air out of their lungs than they’d been able to back when they were still lighting up. Now here’s some bad news: The real marijuana risk has less to do with your lungs than your brain. Of 5,115 adults in a 25-year JAMA Internal Medicine study, those who smoked regularly into middle age had worse verbal fluency than those who cut the habit while they were younger. Also, the more years people smoked marijuana, the less adept they were at recalling words from a list of 15.
Ever gotten a headache after a series of heavy lifts? This is why.
As you load your muscles, your blood vessels (including the ones in your brain) swell to carry more oxygen. If the pressure is too great, you get an exertion headache, says strength coach Mike Donavanik. You can drink water to relieve pressure – blood plasma is mainly H20, so if you’re dehydrated, your blood runs thick. Check your pee; if it’s not clear or a light straw colour, drink up. Or breathe deeply with each rep. Pushing against a closed airway on a heavy lift makes your blood work harder to carry limited oxygen. The resulting blood pressure spike can cause pain.
