I’m a big believer in practical, real-world tools for living well with Type 1 diabetes – the tools you actually reach for when life (or lunch) throws a curveball. High blood sugars happen to all of us, and sometimes they stick around longer than we want. Over the years, I’ve developed a short list of fast, reliable tricks I use to get things back into range depending on the situation.
A quick safety note before we dive in: all of these tactics lower blood sugar. Start with one, give it a little time, and monitor closely so you don’t overcorrect and go low. If you’re on a closed‑loop system, follow its guidance for boluses to avoid insulin stacking. If you’re using multiple strategies (exercise + insulin + Afrezza, for instance), be extra careful about overlap. When in doubt, check with your diabetes care team about how these fit into your personal diabetes strategy.

Blood Sugar Lowering Tools
Get Moving
Exercise is probably my favorite strategy for bringing down a high blood sugar. It’s a good excuse to get some extra steps in and doesn’t require taking extra insulin. Even 5–10 minutes helps.
Movement is one of my go‑to immediate responses. Walking briskly for 5–15 minutes often drops me a decent amount, and it’s portable, low‑risk, and socially acceptable. If I’m home, I might hop on the elliptical or do a few sets of jumping jacks, air squats, or lunges – anything that increases muscle glucose uptake. If I’m stuck at my desk, in the car, or on a plane and can’t really get up, I do “soleus push‑ups” (seated calf raises). They sound weird, but they activate a powerful muscle group and can quickly lower blood sugars..
Why it works: Exercise uses glucose independent of insulin, so short bursts of activity pull sugar into working muscle and lower circulating glucose.
Practical tip: don’t exercise aggressively right after a large bolus as that can create a fast drop. If you’ve recently given insulin, be extra cautious, keep an eye on your blood sugar, and keep a glucose source handy just in case.
Hydrate
Hydration matters more than most people realize. Drinking water helps the kidneys clear excess glucose, and if you’re mildly dehydrated, your blood sugar can read artificially higher. When I have a stubborn high, I reach for water immediately and often some electrolytes (I like LMNT) to help absorb and retain fluid.
Why it works: water dilutes blood and helps flush excess glucose from the body.
Practical tip: avoid sugary sports drinks unless you actually need carbs. Plain water or zero‑sugar electrolyte mixes are the right call for lowering glucose. If you’re vomiting or significantly ill, contact your healthcare provider.
Hot Shower
This one was an idea I learned from Matt Vande Vegte (check out his book The Blood Sugar Freedom Formula), and it surprises a lot of people, but a hot shower is a legit trick. Heat dilates blood vessels and can increase blood flow to the skin and subcutaneous spaces. That improved circulation helps insulin distribute more rapidly and can speed glucose uptake.
Why it works: better blood flow = faster insulin action and more efficient glucose delivery to tissues.
Practical tip: don’t use this as a substitute for insulin when you actually need it. Use a hot shower as an adjunct to get insulin moving more quickly.
Micro-Bolus
When a high won’t budge, I often rely on micro‑boluses which are small correction doses given every 20–40 minutes, guided by my pump or algorithm to avoid stacking. The idea is to give modest amounts that nudge glucose down while the body and insulin do their work, lowering the risk of a rapid overshoot into hypoglycemia.
Why it works: smaller, spaced corrections allow you to respond to ongoing trends rather than guessing a single large dose that could drop you too far.
Practical tip: set a timer or let your pump do the math. If you’re on injections, this approach is trickier. Talk with your diabetes care team about safe split-dosing strategies. Always account for active insulin on board (IOB) so you don’t stack insulin.
Inhaled Insulin
For me, Afrezza is my secret weapon. Because inhaled insulin starts working within minutes, it’s extremely effective at quickly lowering a high, especially when you want speed without additional subcutaneous absorption variability. In many situations this is my sure‑fire way to get a stubborn high moving in the right direction.
Why it works: rapid pulmonary absorption → quick onset of action.
Practical tip: Afrezza has a short duration, so it’s great for correcting highs without a long tail that could cause late lows. It’s not right for everyone (lung health and other contraindications apply), so use it under medical guidance and follow the dosing instructions carefully, since they differ from standard insulin doses.
Rule Out Absorption Issues
Sometimes the problem isn’t insulin amount but where it’s being delivered. If I have an unexplained high, sometimes insulin absorption can be the issue. If I’ve given insulin and am not coming down, or if my blood sugars have been trending high for a few hours for no reason, I’ll change the pod or site. Nine times out of ten that fixes stubborn resistance to corrections.
Why it works: poor absorption from scar tissue, lipohypertrophy, or a kinked cannula means insulin isn’t getting into tissue efficiently. Fresh site = better absorption.
Practical tip: rotate sites regularly and inspect infusion sites for redness, swelling, or leakage. I regularly use a myofascial release roller on my skin where I put my pods to help reduce scar tissue.
Putting it all Together
Because these strategies each lower blood sugars, I strongly recommend starting with one and giving it 15–30 minutes (or the timeframe appropriate for the method) before layering additional interventions until you know the impact they have on your blood sugar. I often combine approaches, for example, a micro‑bolus plus a short walk or water plus Afrezza when I need a fast correction.
Quick decision guide:
- Mild high or trending up after eating: try water + 5–10 minute walk.
- Moderate high: micro‑bolus, check infusion site, consider a short walk or hot shower.
- High that’s urgent or rising quickly: Afrezza for fast correction, then monitor.
- Suspected absorption problem: change the pod/site, bolus, and reassess.
Final Thoughts
Stubborn highs are annoying, but you don’t need to panic. With the right strategy, you can usually bring things back in range fairly quickly. Be patient, start with one tactic, monitor closely, and pick the next step only if you need it.
If highs persist despite your best efforts, reach out to your diabetes care team. Sometimes it’s a settings issue, infection, medication change, or other problem that needs medical attention. Make sure to keep fast-acting low treatments handy. I keep a stash next to my bed, in my purse, and in my car so I am never without some type of fast-acting sugar. If you’re sick, vomiting, or can’t keep fluids down, seek medical care. DKA is a serious risk with persistent high blood sugars.
