Hot or not? When to use a heat treatment
Hot water bottles are fabulous to enjoy as an everyday source of warmth and cosiness. If you're thinking of using one if you are feeling pain or discomfort, do consider the following:
• Applying heat to an area of your body basically loosens muscles and can stimulate blood flow to that area.
• If you have circulation issues, blood flow stimulation is crucial to get your veins pumping blood to all the right places.
• Warmth can also help with muscle flexibility meaning you're less likely to experience strains and sprains.
• If you are using a hot water bottle for pain relief reasons, experts advise only doing so for 20-minute periods at a time.
What is the lifespan of a hot water bottle?
This really depends on how much you use your bottle. The rule of thumb is to replace it every two years, but this might not be necessary if you only use yours occasionally. The best advice is to check your bottle for leaks as you're filling it, and ensure the top is still watertight at every use.
Should you put boiling water in a hot water bottle?
Not according to manufacturers. The common guidance given is don't fill your bottle with water over 80 degrees Celsius, and add some cold water if you're not sure of the temperature. The other safety aspect to consider is to ensure you gently squeeze out any air before you seal the bottle to avoid bottle bursts.
Can I use a hot water bottle every day?
If you follow the safety guidelines, there's no reason you can't use a hot water bottle every day. Just be aware that if you have your bottle close to your skin on a regular basis you could develop "erythema ab igne," a skin reaction rash which is caused by prolonged exposure to heat. If you are concerned you're using your hot water bottle close to your skin too often consider an alternative, such as a heated gilet.
