It seems that what you are experiencing could be a condition known as heat urticaria or cholinergic urticaria. In Ayurveda, such symptoms might relate to an imbalance of Pitta dosha, which can manifest through skin-related issues under exposure to heat.
When your body is exposed to heat, whether from warm water or the sun, it may overstimulate the already aggravated Pitta, leading to the sensation of burning, pins and needles, and the development of itchy bumps.
To alleviate these symptoms, consider incorporating some of the following Ayurvedic strategies:
1. Dietary Modifications: Begin by following a Pitta-pacifying diet. Avoid consuming spicy, sour, and excessively salty foods which can increase Pitta. Instead, opt for foods that are naturally sweet, bitter, and astringent. Fresh fruits like melons, cucumbers, and green leafy veggies are great for cooling down the Pitta dosha.
2. Herbal Remedies: Use herbs like neem and manjistha which are known for their detoxifying and cooling properties. Manjistha can be taken in the form of a capsule or powder with honey, post meals, helping to reduce Pitta accumulation in the skin.
3. Lifestyle Adjustments: Ensure that you wear loose, cotton clothing to let the skin breathe and reduce the risk of irritation. When stepping out in the sun, using cooling oils like coconut oil can help to create a protective barrier on your skin.
4. Hydration: Keep yourself well-hydrated with cool, room-temperature water infused with herbs such as coriander or mint. These can provide cooling from within.
5. Avoiding Triggers: Try avoiding direct sun exposure during peak hours, typically between 10 am and 4 pm. Bathe in cool or lukewarm water instead of hot water.
An Ayurvedic physician can help with a detailed assessment of your ‘Prakriti’ and suggest more precise remedies. If symptoms persist or worsen, consider consulting a dermatologist to rule out any underlying medical conditions.
It sounds like you may be experiencing a Vata-Pitta imbalance, which could be manifesting as heat sensitivity and skin irritation. In the Siddha-Ayurvedic tradition, the symptoms you describe may arise from an aggravated Pitta dosha characterized by excessive heat and inflammation, and heightened Vata that can lead to sensations like pins and needles.
Firstly, addressing your diet can help balance these doshas. Incorporate cooling foods into your diet to pacify Pitta, such as cucumber, coconut water, melons, and green leafy vegetables. Avoid spicy, oily, or excessively hot foods, which could exacerbate your symptoms. Include ghee in moderate amounts as it has a soothing effect on the body.
For external application, you can prepare a paste using sandalwood powder and rose water. Apply it on the affected areas to provide a cooling and calming effect on the skin. It’s important to apply this after you’re out of the sun when your body has cooled down a bit, to naturally soothe the irritation.
Additionally, you may consider practicing Pranayama, particularly Sheetali or Sheetkari breath, which are cooling breathing techniques that can help in calming Pitta.
Given these are recurring symptoms, avoid excessive exposure to sunlight and hot environments. When bathing, use cooler water instead of lukewarm or hot. If symptoms persist or worsen, seeking consultation with an Ayurvedic practitioner or healthcare professional is important to rule out any underlying conditions. This ensures that personal diagnosis and treatment plans are tailored to your unique body constitution and health status.
