Can going to the sauna help your BP?

I will start with a confession.  While I know the benefits of hydotherapy – basically you take a hot shower for 30 seconds then switch to freezing cold for 30 seconds, then go back to hot and repeat for 2 or 3 minutes – it has never appealed to me.  It may be fantastic for blood flow and good for your liver, but to me it seems brutal!  So in the past, I have only spent a few short minutes in a sauna and I have never been tempted to jump into the ice cold plunge pool afterwards – despite my finnish friends telling me how fantastic it is.

So I was interested in the Kuopio Ischaemic Heart Disease Risk Factor Study which looked at if frequent use of a sauna has reduces the risk of high BP.  The study looked at 1,621 middle-aged men living in eastern Finland.  The study found that

  • Going to the sauna 4 to 7 times per week reduces your risk of develping High BP by 46%.
  • Going to the sauna 2 to 3 times per week reduces your risk of develpoing High BP by 24%.

So my Finnish friends who rave about going to the sauna are wise, going regularly helps to keep your BP  in check.

  • How to protect your eyesight as you get older

    I have been wearing glasses since I was a teenager, so I am always interested in how to protect my eyesight.  One of the most common cuases of failing eyesight as we get older is age related macular degeneration (AMD). Scientists tracked the diets and eye health of over 2,000 people who were at least 49 years old at the start of the study.  The people's eye sight and diet were then tracked over the next 15 years.  The researchers discovered that those eating between 100 - 142mg of vegatable nitrates were less likely to have the early signs of AMD.  Currently once AMD starts medicine has no answers and it can in some cases cause blindness. This means prevention of AMD is very important. Vegatable nitrates found in leafy green vegatables and beets reduces the risk of developing AMD by 35%.  100g of spinach contains 20mg of nitrate.  One serving of spinach is 30g, so you would need ot eat 3 servings.

  • The Impact of Sitting All Day – Part 6

    Studies have shown that an alert body and active lifestyle boosts not just productivity, but also happiness and satisfaction levels. There is now an explosion of research studies that demonstrate the harmful effects of sitting all day, which I have covered in past blog posts.

    In my last blog post, "Taking a Break", I explored the reasons for taking a break and looked at the latest research on the length of break you need to take and the frequency. So now I want to focus on strategies to get you moving… Use an Exercise Ball for a Chair Unlike sitting in a chair, sitting on a exercise ball engages your core muscles and helps improve your balance & flexibility. Occasionally bouncing can also help your body interact with gravity to a greater degree than sitting on a stationary chair. Use the Stairs Walk up and down stairs, rather than take the lifts.  Even if you only walk up or down one flight of stairs and then take the lift the rest of the way it will have a positive impact on your health. Walk & Talk Meeting If you have an informal meeting with a colleague why not suggest a walk & talk meeting, weather permitting you could always go outside and get some fresh air too! Pedometer Using a pedometer will help you asses how many steps you take throughout the day. Taking a roundabout way to your desk, taking the stairs or walking to the next tube station as part of your commute will help you increase the number of steps you take daily. Exercise while you Sit at your desk An Amercian start up company, FitnessCubed, has come up with Cubii, an under-desk elliptical trainer that allows you to do basic exercise while you sit at a standard office desk. (It requires no changes to your existing desk set up.) They have also produced a mobile app that allows you to track your workout and you can also share your work out results – so you could even hold an inter-office competition.

  • Natural treatment for cold sores

    A common treatment for cold sores is antiviral cream called aciclovir.  A new randomised controlled trial of nearly 1,000 adults with cold sores where they either applied aciclovir cream or medical grade New Zealand manuka honey to the cold sore. There was no significant difference in the time taken for the cold sore to heal:

    • 8 days for aciclovir cream
    • 9 days with New Zealand medical grade manuka honey
    It should be noted that cold sores can get better within 1 to 2 weeks without treatment and the trail didn't include a no-treatment group.  In addition the trail didn't show that there were any special properties of "medical grade" manuka honey as the trail didn't look at the impact of using  ordinary honey. Basically the trail results show the medical grade mauka honey worked just as well as anitvital cream. Reference https://bmjopen.bmj.com/content/9/5/e026201
