Drinking water is good for you to begin with, but it can help raise your blood pressure if it is too low. Keep a cup of water next to you at all times and sip on it slowly throughout the day. This may not have as pronounced of an effect if you’re younger than 40, but it’s still a healthy, risk-free way to raise your blood pressure a little.  Aim to drink about 8–10 cups (1.9–2.4 L) of water daily. If you're active or feel thirsty, increase your water intake to stay hydrated. Excessive thirst is a common symptom of low blood pressure, so this should help alleviate the symptom as well. If you get sick of boring old water, go ahead and squirt some lime or lemon juice into the water to give it some flavor. Pick up some compression stockings that fit tight, but don’t hurt to wear. These special socks can help increase blood pressure by keeping the blood in your legs from pooling up in your feet. Eat a variety of foods, including fruits, vegetables, whole grains, lean chicken, or fish. This is a good habit to begin with, but it’s especially helpful if you have low blood pressure. Eating a healthy, low-fat diet is an effective way to ensure that your arteries stay healthy and efficient, which is often a problem for people with low blood pressure.  Carbohydrates, sugar, and saturated fats may make your low blood pressure worse. Avoid junk food and sugary drinks as often as possible. Limit the amount of red meat you eat and use lean white meat and fish instead. A turkey or salmon burger can be just as good as beef burger! Other great options include cereal, eggs, and anything with dairy in it. Cheese is a great snack if you have low blood pressure, Oatmeal with some bananas is a phenomenal breakfast or lunch if you’re looking for a filling option. When you eat a large meal, your blood pressure may go up and down rapidly as your body digests the food. Eating smaller meals more frequently is a great way to keep your blood pressure stable over the course of the day. Keep snacks nearby and eat smaller portions to fit in more meals. Simply put, the medical consensus is that too much salt is bad for you. However, for people with low blood pressure, a little extra salt is an efficient way to raise your blood pressure. Talk to your doctor to assess how much salt you should add to your diet, since the amount you can safely consume depends on other health factors.  Do not skip talking to your doctor about this before significantly raising your sodium intake since there are a variety of other health issues that can be triggered by excess salt. Eating too much salt for a longer period of time can lead to kidney disease, strokes, or spikes in your blood pressure.  If you do start increasing your sodium intake to raise your blood pressure, make sure you continue monitoring your blood pressure regularly. Your blood may clot in certain parts of your body when you’re sitting, lying down, or standing in a position for too long. To keep your symptoms from getting worse, change your position every 15-30 minutes. Even small shifts will radically help you from getting dizzy or feeling out of it. When you stand up, do it slowly. You’re more likely to faint or get dizzy when you stand if you have low blood pressure. Aside from the fact that it’s generally not good for your health, drinking a lot of alcohol can drastically lower your blood pressure. Alcohol is a depressant, which causes your blood flow to slow down a little. Consume no more than 1 alcoholic beverage a night to keep your blood pressure safe. It’s particularly important to avoid shots and drinks with a lot of hard liquor. Drinking a lot of alcohol quickly can trigger a sudden drop in blood pressure.

Article: This row is referred to as the “home row” on your concertina. Keep your thumb outside of the straps and use your index finger through your pinky to control the keys on the concertina. If all your fingers cannot reach the keys, practice moving your fingers around to increase their dexterity. Each concertina will have a different layout for their keys depending on how many keys it has and the type you purchased. Refer to the owner’s manual or fingering chart to learn which keys produce the notes you want. Middle C is a good starting note, and on an English concertina, it is typically the key your second finger, or middle finger, rests on in the home row of your left hand. Start with middle C in one of the middle rows of the concertina. Depress the key and either open or close the bellows, depending on what position they’re currently in. The note you selected will play as long as the bellows are moving.  Name the note as you play it to familiarize yourself with the sound. This way, you’ll learn to play the concertina by ear. Find C1 on the opposite side of the concertina as middle C. Play C1 followed by C to hear the difference between the octaves. Look up introductory concertina videos to watch how someone else plays the concertina. These lessons will go over how to properly use and hold the instrument, basic notes, and how to play simple songs. Look for various videos online from different instructors.  Some lessons are usually free on sites like YouTube but will offer further lessons for a small fee on their website. Having a visual reference can be really helpful for beginners.
