A longevity week for over-50s: heat, cold, light and movement

Over the past month we have gone through the research on heat, cold, light and fitness one study at a time. Here is what it adds up to, as a week you can actually follow.

The principles

• Fitness first. Cardiorespiratory fitness is one of the strongest predictors of long life. Read more.
• Heat after training. Fifteen minutes of sauna after exercise lowered blood pressure more than exercise alone. Read more.
• Regular heat. Frequent bathing tracks with lower cardiovascular risk in Finnish research. Read more.
• Cold away from strength days. Read more.
• A gentle cold ramp. Read more.
• Warm water 90 minutes before bed. Read more.
• Safety always. Read more.

A sample week

• Monday: Strength training, then 15 minutes of sauna.
• Tuesday: Brisk walk or ride. Short cold session.
• Wednesday: Strength training, then sauna. Warm water in the evening.
• Thursday: Aerobic intervals. Short cold session.
• Friday: Strength training, then sauna.
• Saturday: Long walk, swim or ride with friends. Shared sauna.
• Sunday: Rest. Warm water 90 minutes before bed.

Get outside in morning daylight every day.

Adjust to you

Start with less. Two sauna sessions and two short cold sessions is a good first month. Build from there.

If you have a heart condition, high or low blood pressure, or are pregnant, speak with your GP before starting.

What is next

We are building Norge-01, our app, to bring this together with your wearable data. And we are happy to help you plan a setup for your home.
